• 2.5D action RPG game

  - by Phorden

  I want to make a 2.5D action RPG game in the next say five years. I need to learn a language first and I have started with C#. I haven't gotten too far into learning it and I would like advice on the best way to approach making a game like this in the long run. Work with XNA studios or stop and learn C++ and UDK? Or maybe there is another good way to approach this. I want to learn programming, so just using a visual editor without learning to code is not the way I want to go. I also don't want to write my game engine from scratch. I'm all ears for advice.

• 2D XNA Tile Based Lighting. Ideas and Methods

  - by Twitchy

  I am currently working on developing a 2D tile based game, similar to the game 'Terraria'. We have the base tile and chunk engine working and are now looking to implement lighting. Instead of the tile based lighting that terraria uses, I want to implement point lights for torches, etc. I have seen Catalin Zima’s shader based shadows, and this would be perfect for the torches (point lights). My problem here is that the tiles on the surface of the world need to be illuminated, doing this by a big point light is firstly extremely expensive, but also doesn't look right. What I need help with (overall) is... To have a surface that is illuminated regardless of torches, etc. To also have point lights, or smooth tile lighting similar to Catalin Zima’s shader based shadows. Looking forward to your replies. Any ideas are appreciated.

• Does the keyword blog in url impove seo?

  - by slow diver

  I have seen a couple of site which has high number of hits. They are mostly tutorial sites and blogs that address software issue/errors. I wonder if the kewybord "blog" has a very positive effect in SEO? In my own site, I have install word press in root folder to avoid any blog keyword. I also did this to keep urls shallow (deeper url are not good for SEO). But I may want to think on it again. The sites I am referring too are http://blog.sqlauthority.com http://veerasundar.com/blog/2011/11/making-xampp-to-serve-any-directory-outside-htdocs/ I know there are standard (sort of) class names or ID that identify different contents and makes it easier for the search engine to identify contents like, "container", "menu". The use of word "blog" would mean this is about dicussing/tutoring something and have a very positive effect on SEO?

• URL length and content optimised for SEO [closed]

  - by Brendan Vogt

  Possible Duplicate: What is the best stucture of SEO friendly URL? I have done some reading on what URLS should look like for search engine optimisation, but I am curious to know how mine would like, I need some advice. I have a tutorial website, and my categories is something like: Web Development -> Client Side -> JavaScript So if I have a tutorial called "What is JavaScript?", is it good to have a URL that looks something like: www.MyWebsite.com/web-development/client-side/javascript/what-is-javascipt Or would something like this be more appropriate: www.MyWebsite.com/tutorials/what-is-javascipt Just curious because I also read that it is wise to have keywords in your URLs. Do I need to add the identifiers of each categories in the link as well, something like: www.MyWebsite.com/1/web-development/5/client-side/15/javascript/100/what-is-javascipt 1 is the unique identifier (primary key) of category web development 5 is the unique identifier (primary key) of category client side 15 is the unique identifier (primary key) of category javascript 100 is the unique identifier (primary key) of tutorial what is javascript

• Meta description of my blog post changes

  - by Aadarsh sojitra

  I have some problems in Meta description tags in my Blogger blog. When I update my pages in search engine with the help of the Fetch as Google feature in GWT, all my blog's results comes with a correct meta description like Today I am back with a reason that "WHY IS ORIGINAL MEMORY IN HARD-DISK IS LESS THAN PRINTED" on a box. If we buy any hard-disk or a pen drive... But after approx 5-6 days, it changes to my blog's default meta description. This is also happening after changing the default meta description of my blog. I want only one answer that why its happening? After deleting my blog and creating a new blog with the same name this problem was solved. Why this problem was solved? - I am asking this question because to solve problems in the future.

• Coolbits not working

• Is there any reason to allow Yahoo! Slurp to crawl my site?

  - by James Skemp

  I thought a year or more ago Yahoo! would be using another search engine for results, and no longer using their own Slurp bot. However, a couple of the sites I manage Yahoo! Slurp continues to crawl pages, and seems to ignore the Gone status code when returned (as it keeps coming back). Is there any reason why I wouldn't want to block Yahoo! Slurp via robots.txt or by IP (since it tends to ignore robots.txt in some cases anyways)? I've confirmed that when the bot does hit it is from Yahoo! IPs, so I believe this is a legit instance of the bot. Is Yahoo Search the same as Bing Search now? is a related question, but I don't think it completely answers whether one should add a new block of the bot.

• How many SQL Server DBAs does an organization need?

  - by RickHeiges

  "How many SQL Server DBAs do we need?" - This is a question that often comes up in conversations with customers. Essentially, customers want to know if they have enough DBAs or too many. This is not a trivial question. If you do some research online via your favorite search engine, you will most likely come across numbers such as 40-65 DBs per DBA (for SQL Server). I remember finding another number relating to storage space instead of the number of DBs; the range was 3-5TB per DBA. I have had custoemrs...(read more)

• Implementing 2D CSG (for collision shapes)?

  - by bluescrn

  Are there any simple (or well documented) algorithms for basic CSG operations on 2D polygons? I'm looking for a way to 'add' a number of overlapping 2D collision shapes. These may be convex or concave, but will be closed shapes, defined as a set of line segments, with no self-intersections. The use of this would be to construct a clean set of collision edges, for use with a 2D physics engine, from a scene consisting of many arbitrarily placed (and frequently overlapping) objects, each with their own collision shape. To begin with, I only need to 'add' shapes, but the ability to 'subtract', to create holes, may also be useful.

• I prefer C/C++ over Unity and other tools: is it such a big downer for a game developper ?

  - by jokoon

  We have a big game project on Unity at school on which we are 12 to work on. My teacher seems to be convinced it's an important tool to teach students, since it makes students look from the high level to the lower level. I can understand his view, and I'm wondering: Is unity such an important engine in game developping companies ? Are there a lot of companies using it because they can't afford to use something else ? He is talking like Unity is a big player in game making, but I only see it fit small indie game companies who want to do a game as fast as possible. Do you think Unity is that much important in the industry ? Does it endangers the value of C++ skills ? It's not that I don't like Unity, it's just that I don't learn nothing with it, I prefer to achieve little steps with Ogre or SFML instead. Also, we also have C++ practice exercises, but those are just practice with theory, nothing much.

• First time android game development [on hold]

  - by Dave

  My friend and i are developing a android game. This is my first time develop android game, so we don't know how to code The game is 2d game and we develop it without 3rd party engine / framework. Now we got a few questions, hope you can help us. In game play, using 'Surfaceview' only to achieve it. Is it best practice? On 'Surfaceview', a lot of difference button(Menu, pause, game object..etc) is on it, but I don't know how to code it? (actually, i have already done, but...so stupid way. Detect the user touch position (x, y) to identify where they touch[rect(x1,y1,x2,y2).contain(x,y)] Is it right? Teach me how to do if wrong. View / Surfaceview / OpenGL, which is suitable for us? (if like Tetris) Thank you for your help. Ps: My english is not good, hope you can understand what i mean.

• Sequence for authentication on a decoupled client?

  - by A T

  Using a sequence diagram and example code could you explain to me how authentication works when the client is completely separated from the server? I.e.: you haven't generated any of the client using a server-side template engine, rather you are communicating using REST (SOAP xor HTTP) xor RPC (XML xor JSON) with javascript on the client-side. Specifically I would like to know the sequence of: Authenticating using basic auth (user+pass) with "my" server Authenticating using OAuth2, e.g.: with Facebook, with facebook's server then whatever extra steps are needed for "my" server And how it could be implemented. (feel free to use psuedo-code [like below] or [preferably] prototyped simply using BackboneJS, AngularJS, EmberJS, BatmanJS, AgilityJS, SammyJS xor ActiveJS. if cookie.status in [Expired, Tampered, Wrong IP, Invalid, Not Found]: try auth(user,pass): if user is in my db: try authenticate(user,pass) if successful: login user # give session-cookie here? else: present user with "auth failed" msg else if user not in db: redirect to "edit-profile" page PS: I have written an example (editable) auth sequence diagram; based on facebooks' documentation.

• XAudio2 - Multiple instances of the same sound

  - by Boreal

  Right now, I'm adding a rudimentary sound engine to my game. So far, I am able to load in a WAV file and play it once, then free up the memory when I close the game. However, the game crashes with a nice ArgumentOutOfBoundsException when I try to play another sound instance. Specified argument was out of the range of valid values. Parameter name: readLength I'm following this tutorial pretty much exactly, but I still keep getting the aforementioned error. Here's my sound-related code. http://pastebin.com/FgaqfXTs The exception occurs on line 156 when I am playing the sound: source.SubmitSourceBuffer(buffer);

• car crash android game

  - by Axarydax

  I'd like to make a simple 2d car crashing game, where the player would drive his car into moving traffic and try to cause as much damage as possible in each level (some Burnout games had a mode like this). The physics part of the game is the most important, I can worry about graphics later. Would engine like emini or box2d work for this kind of game? Would Android devices have enough power to handle this? For example if there were about 20 cars colliding, along with some buildings, it would be nice if I could get 20 fps.

• Convert rotation from Right handed System to left handed

  - by Hector Llanos

  I have Euler angles from a right handed system that I am trying to convert to a left handed system. All the information that I have read online says that to convert it simply multiply the axis and the angle in the correct order and it should work. In other words, Z * Y * X. When I do this what I see in Maya, and in engine still do not match up. This is what I have so far: static Quaternion ConvertToRightHand(Vector3 Euler) { Quaternion x = Quaternion.AngleAxis(-Euler.x, Vector3.right); Quaternion y = Quaternion.AngleAxis(Euler.y, Vector3.up); Quaternion z = Quaternion.AngleAxis(Euler.z, Vector3.forward); return (z * y * x); } Keeping the -Euler.x helps keep the object pointing up correctly, but when I pass ( 0,0,0) to face in the -z, it faces in the +z. Help :/

• Determine percentage of screen covered by an object without using frustum culling

  - by Meltac

  On the CPU-side of an 3D first-person / ego perspective game I need to check whether what the players currently sees on screen is the inside of a box object defined by world space coordinates (the player might be outside of that box but on screen sees only/mostly the inside of the box, or vice-versa, looks from within the box to the outside). The "casual" way of performing such a check would incorporate frustum culling but such an approach would be hard to achieve with my given set of engine parameters which I'd like to avoid if there is a simpler way. What I actually have at the point where I would like to do the check (high-level script on CPU, not GPU side): Camera world position Camera direction Camera FOV Two Box corner world coordinates (left-bottom-front, right-top-back) What I do not have right away: View frustrum definition (near/far plane or say 6 planes defining frustum) Any specific pixel information (uv, view space position, depth or the like) What I would like to calculate: Percentage of screen "covered" by box. Any hints on how to perform such calculation?

• Migration from XNA to SharpDX

  - by Wouter

  My fear is that XNA has reached the end of the road. To keep up with the latest technology a shift to another game framework might be needed. We have many games in a large codebase, all based on XNA. My question is, how much work would it be to migrate to SharpDX and are there other possibilities? Our code base mainly uses basic 3D rendering and the SpriteBatch, no fancy shader stuff. Update: I should have mentioned we only use 2.5D, we have a simple engine that builds textured quads to render text and animated sprites. Also for sound we use XACT (what else..) with some effects.

• How to remove duplicate content, which is still indexed, but not linked to anymore?

  - by David

  A bug in the tool, which we use to create search-engine-friendly URLs changed our whole URL-structure overnight, and we only noticed after Google already indexed the page. Now, we have a massive duplicate content issue, causing a harsh drop in rankings. Webmaster Tools shows over 1,000 duplicate title tags, so I don't think, Google understands what is going on. Right URL: abc.com/price/sharp-ah-l13-12000-btu.html Wrong URL: abc.com/item/sharp-l-series-ahl13-12000-btu.html (created by mistake) After that, we ... Changed back all URLs to the "Right URLs" Set up a 301-redirect for all "Wrong URLs" a few days later Now, still a massive amount of pages is in the index twice. As we do not link internally to the "Wrong URLs" anymore, I am not sure, if Google will re-crawl them very soon. What can we do to solve this issue and tell Google, that all the "Wrong URLs" now redirect to the "Right URLs"? Best, David

• Handbrake-powered VidCoder gets a native 64-bit version

  A while back, VidCoder -- the Windows video disc ripping program -- added support for Blu-ray discs. With Handbrake's engine under the hood, VidCoder offers an easy-to-use interface and simple batch processing of your video files. With the release of version 0.8, there's also now a native 64-bit version for those of you running Windows x64. A number of stability tweaks have also been introduced. As Baz pointed out in our comments last time, VidCoder is particular useful on netbooks. If you've got a 1024x600 screen, Handbrake may not even launch for you -- but VidCoder will fire up just fine. Take the new 64-bit version for a spin, and share your thoughts in the comments.

• How do I export physique animations without breaking them?

  - by Paul Ferris

  I've been trying to export a simple footstep animation that I made in 3ds Max, but its either failed to export or broken (imported into unity sans a few frames, or appearing to have imported but not playing) every single time. I've tried .fbx and .3ds, but neither works. I'd rather not use the Skin modifier, because it would require starting from scratch and learning a new system. Any ideas? EDIT: I found a workaround, here it is if you're curious: Create your biped, and make sure it lines up with your mesh. Animate it Export the mesh without Physique (or with Physique turned off), then delete it (the mesh) Export the biped Recombine in Unity (or whatever your game engine of choice is)
