• Rainmeter customization issues, pretty basic

  - by user62865

  I'll admit it; I'm new to using Rainmeter. What I want to do is create two panels (one left, the other on the right) that mirror one another. One side I want to work for the Eastern US while the other for the UK. I want to keep digital clocks, the same style etc., on both sides with their respective time zone. On top of this I want to have weather reports for the whole day (Current weather and temp, morning, afternoon, and night) for each location. However, I have not been able to find any skins which allow this. For whatever reason every time I try to load a skin for a clock I can only load it for one clock of that type and I'm having the same issue with the weather skins. Could anyone please tell me what skins I should look at and how to get a mirrored look?

• Interesting sessions/tips from RMOUG

  - by jean-pierre.dijcks

  One of the sessions I was at at last week's RMOUG was a session on Temp Tablespace Groups. I had a look because I had no experience with this and it seemed to help with parallel processing and the allocation/usage of temp. You can read the excellent write-up at Kellyn Pedersen's blog - who did the session and all the work - here. So for all of those who may be seeing lot's of waits like enq: TS - Contention when you are doing hash joins and sorts, do have a look at the above blog post. I also had the chance to listen in at Stewart Bryson's session on Restartability (he had 3 R-s) where he gave very useful tips about how to deal with your data warehouse loads. Questions like archive log mode - should I or should I not were well covered. Flashback archives, also nice to hear about. Very nice talk, very interesting. Unfortunately he hasn't blogged about it yes, so no pointers to that one. Got to see a couple of other interesting sessions, and as conferences go got to meet some interesting Oracle folks from the region. As usual RMOUG was useful and fun. Off to the drawing boards to design next year's session!

• Magento 1.6.2 Catalog Price Rule Problem

  - by robgt

  My Magento system seems to have a slight issue with Catalog Price Rule application. As far as the customer is concerned, all is working perfectly. The problem is that some orders are not being displayed properly in the admin system when I look at the details. The Catalog Price rule appears to not be applied - so when we reconcile our card processor details with those in our backend Sage system, numbers are not tallying up. Magento and out Sage system say the customer paid X, but the card issuer has taken payment of Y. The payment amount is correct due to the Catalog Price Rule. The customer is always paying the correct amount, but because of some issue with Magento, I think the data is possibly not being stored correctly (stored without the catalog price rule discount amount applied). This means that when I look at an order in the admin system, the line item prices that should be affected by the catalog price rule are not - but also the prices in our backend Sage system are incorrect too. We use another piece of software to bring the data into Sage from Magento, so the data must be stored in Magento's database incorrectly somewhere as this software reads out the order information from Magento. Does anyone have any idea what is wrong here, and how it might be fixed? Cheers!

• checking for collision detection

  - by bill

  I am trying to create a game where you have a player and you can move right,left, and jump. kind of like mario but its not a side scroller. also i want to use 2d array to make a tile map. my big problem is that i dont understand how to check for collision. i spend about 2 week thinking about this and i came up with 2 solution but they both have problems. let say my map is: 0 = sky 1 = player 2 = ground 00000 10002 22022 Solution 1: move the '1'(player) and update the map less say player wants to move right, then x+=grid[x+1][y] this make the collision easy bc you can just check if if(grid[x][y+1] == 2){ //player is standing on top of ground } problem with this when u hit right key player will move (x*Titlewidth) to right. and as you can see the animation wont look smooth. Solution 2: move player and dont update map player_x += 2 this will make the animation more smoother bc i am just moving 2 pixels. problem1: i cant update map bc if player some times will be middle of int(2d array). but thats ok sinces its not a side scroller so updating the map is not a big deal. problem2: only way to check for collision is to use java intersection method. but then player have to be atleast 1 or 2 pixel in ground in order to check for collision. and as you can see that wont look good too. plz note this is my first collision game in java. so plz try to explain alot otherwise i wont understand it.

• Modify .htm files on wireless router

  - by mdeitrick

  What am I trying to do? I am attempting to access the .htm files on my wireless router to modify the look and feel of the Netgear GENIE webpage(s). What have I done? I've read several articles on eHow and Instructables that detail how to setup your router as an FTP server, since I figured the best way to access the files would be through FileZilla. Setting up an FTP server through my router doesn't sound like what I should do to accomplish my task... or perhaps it is? I've also read the documents provided by Netgear for getting started and setting up functionality on the router. Maybe I overlooked something? My specifications Netgear router WNR2000v3 FileZilla v3.8.1 UPDATE: Since someone voted to close this question I'll clarify what I'm asking for... At the present I am dissatisfied with the current UI/webpage look when logging into routerlogin.net. Furthermore I would like to make changes to the admin dashboard.

• Determining Performance Limits

  - by JeffV

  I have a number of windows processes that pass messages between them hat a high rate using tcp to local host. Aside from testing on actual hardware how can I assess what my hardware limit will be. These applications are not doing CPU intensive work, mostly decomposing and combining messages, scanning over them for special flag in the data etc.. The message size is typically 3k and the rate is typically ~10k messages per second. ~30MB per second between processing stages. There may be 10 or more stages depending. For this type of application, what should I look to for assessing performance? What do I look for in a server performance wise? I am currently running an XEON L5408 with 32 GB ram. But I am assuming cache is more important than actual ram size as I am barely touching the ram.

• Excel; exporting/importing different columns to different csv files

  - by Sisyphus

  Is there a way to batch export different columns to different csv files in excel on an OSX, I'm thinking something along the lines of possibly automator, applescript or bash. I've had a look play around with automator and so far no look. The best I have accomplished export the whole sheet, then use sed to strip out what I don't need, however this is terribly inefficient. Also, is there a method, to batch import multiple csv files into columns. Thanks in advance && sorry I didn't tag excel correctly it wouldn't allow me to create the excel:mac tag

• Migrating Forms to Java or ADF, the truth and no FUD

  - by Grant Ronald

  The question about migrating Forms to Java (or ADF or APEX) comes up time and time again.  I wanted to pull some core information together in a single blog post to address this question. The first question I always ask is "WHY" - Forms may still be a viable option for you so "if it ain't broke don't fix it".  Bottom line is whatever anyone tells you, its going to be a considerable effort and cost to migrate from Forms to something else so the business is going to want to know WHY you spend all those hard earned dollars switching from something that might have been serving you quite adequately. Second point, if you are going to switch, I would encourage you NOT to look at building a Forms clone.  So many times I see people trying to build an ADF application and EXACTLY mimic the Forms model - ADF is NOT a Forms clone.  You should be building to the sweet spot of your target technology, not your 20 year old client/server technology.  This is also the chance for the business to embrace change, so maybe look at new processes, channels and technology options that weren't available when you first developed your Forms applications. To help you understand what is involved, I've put together a number of resources. Thinking about migration of Forms to Java, ADF or APEX, read this to prepare yourself Oracle Forms to ADF: When, Why and How - this gives you an overview of our vision, directly from Oracle Product Management Redeveloping a Forms Application with Oracle JDeveloper and Oracle ADF.  This is a conference session from myself and Lynn Munsinger on how ADF can be used in a Forms migration/rewrite As someone who manages both Forms and ADF Product Management teams, I've a foot in either camp and am happy to see you use either tool.  However, I want you to be able to make an informed decision.  My hope is that there information sources will help you do that.

• Where&rsquo;s my start button?

  - by Dennis Vroegop

  I have to be honest here for a moment. The one thing people most complain about when they talk about Windows 8 is that they miss the Start Button. You know, that dreaded thing that everybody hated when it was introduced… I usually don’t go into these kinds of discussions unless I am personally involved but this one I cannot let go. Why are people doing this? Windows 8 is a great OS. They have changed, updated and perfected so many things so there is enough to talk or write about. Yet, all articles or discussions come down to “Where’s my start button?” In order to save myself from having to explain this every single time I wrote this post and from now on I will simply refer to this blog when I get asked that question. Here it is. Your start menu is there. It’s right in front of your nose. It’s two dimensional, it’s got huge buttons (although they are more than just buttons, they’re alive and therefore called Live Tiles). Just go through those tiles and click what ever you want to start up. Don’t want to look for an item? Just start typing. Really it is that simple. When you are on the start screen just start typing (part of) the name of the program you want and you’ll find it.  As you see in the attached example I started typing “word” and it found Word, Wordfeud, Wordament etc. If you want to find something else besides a program (say you want to change the region you’re in) just click on Settings (it will already show you how many hits there are in that section). People, my request is: dive into something before you complain about it. Look around. This feature is so much easier to use than the old stuff. But you have to know about it. So. I won’t get into this discussion anymore.

• How can I perform 2D side-scroller collision checks in a tile-based map?

  - by bill

  I am trying to create a game where you have a player that can move horizontally and jump. It's kind of like Mario but it isn't a side scroller. I'm using a 2D array to implement a tile map. My problem is that I don't understand how to check for collisions using this implementation. After spending about two weeks thinking about it, I've got two possible solutions, but both of them have some problems. Let's say that my map is defined by the following tiles: 0 = sky 1 = player 2 = ground The data for the map itself might look like: 00000 10002 22022 For solution 1, I'd move the player (the 1) a complete tile and update the map directly. This make the collision easy because you can check if the player is touching the ground simply by looking at the tile directly below the player: // x and y are the tile coordinates of the player. The tile origin is the upper-left. if (grid[x][y+1] == 2){ // The player is standing on top of a ground tile. } The problem with this approach is that the player moves in discrete tile steps, so the animation isn't smooth. For solution 2, I thought about moving the player via pixel coordinates and not updating the tile map. This will make the animation much smoother because I have a smaller movement unit per frame. However, this means I can't really accurately store the player in the tile map because sometimes he would logically be between two tiles. But the bigger problem here is that I think the only way to check for collision is to use Java's intersection method, which means the player would need to be at least a single pixel "into" the ground to register collision, and that won't look good. How can I solve this problem?

• Which approach would lead to an API that is easier to use?

  - by Clem

  I'm writing a JavaScript API and for a particular case, I'm wondering which approach is the sexiest. Let's take an example: writing a VideoPlayer, I add a getCurrentTime method which gives the elapsed time since the start. The first approach simply declares getCurrentTime as follows: getCurrentTime():number where number is the native number type. This approach includes a CURRENT_TIME_CHANGED event so that API users can add callbacks to be aware of time changes. Listening to this event would look like the following: myVideoPlayer.addEventListener(CURRENT_TIME_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().getCurrentTime()); }); The second approach declares getCurrentTime differently: getCurrentTime():CustomNumber where CustomNumber is a custom number object, not the native one. This custom object dispatches a VALUE_CHANGED event when its value changes, so there is no need for the CURRENT_TIME_CHANGED event! Just listen to the returned object for value changes! Listening to this event would look like the following: myVideoPlayer.getCurrentTime().addEventListener(VALUE_CHANGED, function(evt){ console.log ("current time = "+evt.getDispatcher().valueOf()); }); Note that CustomNumber has a valueOf method which returns a native number that lets the returned CustomNumber object being used as a number, so: var result = myVideoPlayer.getCurrentTime()+5; will work! So in the first approach, we listen to an object for a change in its property's value. In the second one we directly listen to the property for a change on its value. There are multiple pros and cons for each approach, I just want to know which one the developers would prefer to use!

• Software for formatting / web-publishing tutorial-type, technical articles

  - by gojira

  I want to put some of my own technical writing on the web: tutorials, how-to's, conceptual articles about programming etc. I write mostly for myself yet, but think others can benefit from it so I want to put it online, and I also have plans of making everything more coherent and turning it into a book. My articles are not meant as a blog, they're just meant as a collection of tutorials and how-to's, but I think a blog-type software would probably be the most appropriate mode of formatting that kind of stuff. Right now I am using the blog feature of cite u like, which is very low tech and I really need something better. On my wish list is, among other things: code snippets in scrollable boxes syntax highlighting for source code snippets tagging articles with graphical icons according to topic, like in slashdot of course users (i.e. readers) should be able to comment on articles Also, just more options than a super-simple blog should look slick! should not look wikipedia-like Is there any software you can recommend for this purpose?

• Is there a search engine that indexes source code of a web-page?

  - by Dexter

  I need to search the web for sites that are in our industry that use the same Adwords management company, to ensure that the said company is not violating our contract, as they have been accused of doing. They use a tracking code in the template of every page which has a certain domain in the URL, and I'm wondering if it's possible "Google" the source code using some bot that crawls the code rather than the content? For example, I bought an unlimited license for an image gallery, and I was asked to type the license number in a comment just before the script. I thought it was just so a human could look at the source and find out if someone paid, but it turned out that it was actually that they had a crawler looking for their source code and that comment. If it ran across the code on your site, it would look for the comment, and if it found one, it would check to see if it was an existing one. If not, it would first notify you of your noncompliance, and then notify the owner of the script. Edit: I'm looking to index HTML and JavaScript only, not the server-side languages or Java.

• PASS Location fixed for the next 2 years - Are they listening?

  - by simonsabin

  I've just received the PASS connector newsletter with details of the decision of where to locate the next summits. To me it shows you how you can spin statistics they way you want to. I am very suprised by the numbers 81% said that they would like an east coast event. The spin is that "When we look at responses from only 2008 and 2009 Summit attendees (our most successful ones by far), the number who want a future Summit outside of Seattle drops to 69%." Wow the number drops thats bad. We must stay in Seattle then. My take however is that 69% of those willing to travel to Seattle want an event NOT in Seattle. Doesn't that suggest that people would like an event not in Seattle. I appreciate the comment about the launch years however 2012 isn't going to be a launch year because they need to get SQL out of the door before then to meet the 3 year software assurance cycle. So sticking 2012 in Seattle is IMHO a bad decision. It might keep the cost down for the PASS org, Microsoft and the attendees that live near Seattle but does it keep the cost down for the rest of the SQL Community? They do mention a possibility of an event on the East Coast and I do hope that its not just lip service. Flights for me to the East coast look ~30% cheaper than to Seattle and I've never been to the East Coast. Come on PASS show you are listening to the community.

• FTP Issue when connecting to a debian machine from windows

  - by erin c

  I have a .net application which copies bunch of files to a specific FTP folder on a debian machine on periodical basis, ftp folder has 755 mod, owner of the directory is the ftp username that I authenticate in .net application. So far I tested this application with bunch of debian boxes, my initial attempts generally fail with following message if I try it with a debian machine that I haven't tried it before: "remote server returned an error 550 File unavailable" When I see this error, I log onto another debian machine on my network, and I try FTP'ing the debian box that returns the error message from command line. I generally "put" a very small file to the folder in question, right after that windows application starts copying files successfully via FTP. It is as if my command line ftp operation fixes the problem and makes debian compatible with my .net application. I checked permissions before and after the problem, it doesn't look like what I did changed anything, I am at loss understanding why this problem occurs and why it is fixed with my silly hack. Can anybody tell me where to look at next to fix this extremely annoying issue?

• Windows 7+ desktop apps - what's the best UI toolkit for a new project?

  - by Chris Adams

  I'm trying to make a decision for a new Windows desktop app: what to use for the UI. (This is a desktop app that needs to have compatibility with Windows 7. It won't be distributed on the Windows Store.) This application is going to be cross-platform. I intend on writing the core in C++, and using each platform's native UI toolkit. I feel this is preferable to using a cross-platform toolkit like Qt, as it allows me to keep the native look and feel of each platform. On the Windows side, the UI situation isn't exactly clear. I'm getting the feeling that Microsoft is slowly abandoning .NET, particularly as their preferred toolkit for desktop apps. Indeed, the Getting Started chapter for Windows 7, as well as the rest of Microsoft's documentation, seems to be more suited for C++. I have a few options here: C# with WPF - This sesms like this might be the best Microsoft has to offer for Windows 7 desktop apps, even if it isn't their "preferred" toolkit. I'd need to use P/Invoke to call my C++ code. C++ with Direct2D - This is what Microsoft used in one of their examples. This feels like it's too low-level. Part of the appeal of a higher-level UI toolkit is the consistency with the native look and feel of the platform, so doing this would just feel strange. C++ with a third-party UI toolkit, like Qt There might be some other options I'm missing, which I'd love to hear about. So, if you were starting a new Windows 7+ desktop app today, what would you use?

• How do I mashup Google Maps with geolocated photos from one or more social networks?

  - by PureCognition

  I'm working on a proof of concept for a project, and I need to pin random photos to a Google Map. These photos can come from another social network, but need to be non-porn. I've done some research so far, Google's Image Search API is deprecated. So, one has to use the Custom Search API. A lot of the images aren't photos, and I'm not sure how well it handles geolocation yet. Twitter seems a little more well suited, except for the fact that people can post pictures of pretty much anything. I was also going to look into the API's for other networks such as Flickr, Picasa, Pinterest and Instagram. I know there are some aggregate services out there that might have done some of this mash-up work for me as well. If there is anyone out there that has a handle on social APIs and where I should look for this type of solution, I would really appreciate the help. Also, in cases where server-side implementation matters, I'm a .NET developer by experience.

• At what point would you drop some of your principles of software development for the sake of more money?

  - by MeshMan

  I'd like to throw this question out there to interestingly see where the medium is. I'm going to admit that in my last 12 months, I picked up TDD and a lot of the Agile values in software development. I was so overwhelmed with how much better my development of software became that I would never drop them out of principle. Until...I was offered a contracting role that doubled my take home pay for the year. The company I joined didn't follow any specific methodology, the team hadn't heard of anything like code smells, SOLID, etc., and I certainly wasn't going to get away with spending time doing TDD if the team had never even seen unit testing in practice. Am I a sell out? No, not completely... Code will always been written "cleanly" (as per Uncle Bob's teachings) and the principles of SOLID will always be applied to the code that I write as they are needed. Testing was dropped for me though, the company couldn't afford to have such a unknown handed to the team who quite frankly, even I did create test frameworks, they would never use/maintain the test framework correctly. Using that as an example, what point would you say a developer should never drop his craftsmanship principles for the sake of money/other benefits to them personally? I understand that this can be a very personal opinion on how concerned one is to their own needs, business needs, and the sake of craftsmanship etc. But one can consider that for example testing can be dropped if the company decided they would rather have a test team, than rather understand unit testing in programming, would that be something you could forgive yourself for like I did? So given that there is something you would drop, there usually should be an equal cost in the business that makes up for what you drop - hopefully, unless of course you are pretty much out for lining your own pockets and not community/social collaborating ;). Double your money, go back to RAD? Or walk on, and look for someone doing Agile, and never look back...

• Doubling the DPI with a shader?

  - by Mathias Lykkegaard Lorenzen

  I'm developing a game where the map is generated with Perlin Noise, but on the CPU. I am generating some perlin noise onto a texture with a small size, and then I stretch it out to the whole screen to simulate a map. The reason for the CPU generating the noise is that I want it to look the same on all devices. Now, here's the end-result. Please ignore the bullets and the explosion on the picture. What matters is the background (the black/gray pixels) and the ground (the brown-ish pixels). They are rendered to the same texture through perlin noise. However, this doesn't look very pretty. So I was wondering if it would be possible to double the amount of pixels using a shader, and rounding edges at the same time? In other words, improve the DPI. I'm using SharpDX with DirectX 11, through its toolkit feature. But any help that'll lead me in the right direction (for instance through HLSL) would be a great help. Thanks in advance.

• Web.NET event coming in October

  - by Chris Massey

  If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

• Help me select a "Simpler" target to create a new language: .NET, LLVM, Go, Own VM

  - by mamcx

  Lets define "Simple". This is my first language. I have no previous experience I will not dedicate +4 years to learn it properly. I'm a professional software [developer], but as an amateur in this area, I want instant gratification. If the idea shows a future, I could rewrite it. I don't want to do everything from scratch. In fact, if there exists a way to get GO (for example), change its syntax, add some sugar, give some extra functions and leave intact everything else, that would be perfect! From the example of coffescript/scala I think is better to build on top of some rich runtime like .NET/GO so I don't need to rewrite everything. HOWEVER, if is better other way, no problem for the first try! I want it in a week. I need it in a week so it will really take a month. Then it truly takes 3 months. But I don't want to put more that 3 months on this. I could reduce the scope of my language, but I hope the tools will help me a lot... I want to build a new language. Similar to python, but typed. I wonder what to build it on top of. I like the idea of building on top of GO. To get their sane (IMHO) OO paradigm (I plan to do the same, using interfaces, not inheritance), get goroutines and some other stuff. In my naive thinking I imagine that spit another language could help me to debug it more easily. However, look like everyone is building on top of something like .NET (don't like Java), LLVM or make it own VM. I read http://createyourproglang.com/ (great!) and the part of the VM look "easy" to me. So, what I need is the proper criteria and question I need to know in advance to have a fair shot at make this.

• Extending an ABCS

  - by jamie.phelps

  All AIA Application Business Connector Services (ABCS) are extension enabled out of the box. The number and location of extension points in each ABCS is dependent upon whether the ABCS is a request-response or fire-and-forget service. Below is an example of a request-reply ABCS with 4 extension call-out points: Pre-transformationPost-transformation, Pre-invokePost-invoke, Pre-transformationPost-transformation, Pre-reply You can also see in the diagram that each XSL Transformation has it's own extension call-out. However for now we are only discussing the ABCS extension call-outs. To extend an ABCS, you'll first need to identify the specific extension points that are available in your ABCS and choose the one or more that you want to implement. You can an get an idea of the extension points available in your ABCS by looking into the AIAConfigurationProperties.xml file found under the AIA_HOME/config directory. Find the for your ABCS and look for properties similar to the following: false false false false Each extension point in the ABCS will have a corresponding configuration property to control whether or not the extension call-out is active at runtime. So these properties can give you some idea of what extension points are available in your ABCS. However, you'll probably also want to look into the ABCS BPEL code itself to confirm the exact location of the call-out.

• Reflection and the params Keyword

  - by Robert May

  I’ve had to look this up a couple of times, and there’s not much out there, so I end up guessing the same answer over and over. When using MethodBase.GetParameters() to get an array of ParameterInfo object, I often want to get a count of the number of parameters that are out, optional, params, etc.  For out and optional, you can simply check ParameterInfo.IsOut or ParameterInfo.IsOptional or any number of other “Attributes”. However, for params, there isn’t a property on ParameterInfo.  Instead, you have to do this: info.GetCustomAttributes(typeof(ParamArrayAttribute), true) This will get you a set of all of the attributes that are the ParamArrayAttribute, which you can then turn into a linq statement that looks like this: methodParameters.Count(info => info.GetCustomAttributes(typeof(ParamArrayAttribute), true).Count() > 0); Which, assuming that methodParameters is the result of MethodBase.GetParameters, will give you a count of the number of parameters that have the params keyword.  Of course, there can be only one, but who’s counting! Now, hopefully, the next time I try to look this up, my own blog will get the values. Technorati Tags: Reflection

• Diablo 3 "freezes" periodically

  - by Shauna

  I'm running Diablo 3 (start edition, digital download) on the following: Ubuntu 12.04 64-bit (stock Unity, Gnome, etc; kernel version 3.2.0-29-generic) Wine version 1.5.11 (base, from Wine's PPA, game started with setarch i386 -3) Intel i7 920 CPU nVidia GTX260 with driver version 295.49 ("post-release updates" entry within the proprietary drivers tool), dual monitors 6GB RAM Every so often (and what appears to be at random), the game video will freeze up. I can still move the mouse, and it reacts to ctrl+alt+f2 to drop into text mode, but I can't get back to the desktop (which means I can check terminal to see what's going on after launching from terminal, especially since even in windowed mode, the secondary screen gets shut off by the game), and I can't continue to play the game. In order to get it running again, I have to restart lightdm, then relaunch the game (or, in a couple of rare cases, I had to restart the computer entirely, because running sudo service lightdmn [stop/start] doesn't appear to react). Turning down the video settings seems to have helped in some cases, but not all of them. Times it's frozen on me: The beginning of The Fallen Start quest part 6 - kill the Wretched Mother, right as you walk out of New Tristram and engage in the monsters on the northern path (repeatedly froze here until I adjusted the graphics down) Within the cinematic/event upon finding Deckard Cain While fighting the skeletons to protect Deckard Cain When about to enter Leoric's passage after Cain sends you back to where you found him That's as far as I've gotten through the game so far. Additionally, this doesn't happen on other games I play and seems to only occur with Diablo 3. Has anyone else run into this issue and know a possible cause or fix, or at least know where I can look (and what to look for) to figure out why this is happening?

• Problem with Ogre::Camera lookAt function when target is directly below.

  - by PigBen

  I am trying to make a class which controls a camera. It's pretty basic right now, it looks like this: class HoveringCameraController { public: void init(Ogre::Camera & camera, AnimatedBody & target, Ogre::Real height); void update(Ogre::Real time_delta); private: Ogre::Camera * camera_; AnimatedBody * target_; Ogre::Real height_; }; HoveringCameraController.cpp void HoveringCameraController::init(Ogre::Camera & camera, AnimatedBody & target, Ogre::Real height) { camera_ = &camera; target_ = &target; height_ = height; update(0.0); } void HoveringCameraController::update(Ogre::Real time_delta) { auto position = target_->getPosition(); position.y += height_; camera_->setPosition(position); camera_->lookAt(target_->getPosition()); } AnimatedBody is just a class that encapsulates an entity, it's animations and a scene node. The getPosition function is simply forwarded to it's scene node. What I want(for now) is for the camera to simply follow the AnimatedBody overhead at the distance given(the height parameter), and look down at it. It follows the object around, but it doesn't look straight down, it's tilted quite a bit in the positive Z direction. Does anybody have any idea why it would do that? If I change this line: position.y += height_; to this: position.x += height_; or this: position.z += height_; it does exactly what I would expect. It follows the object from the side or front, and looks directly at it.
