  • Path Modifier in Tower Of Defense Game

    - by Siddharth
    I implemented PathModifier for path of each enemy in my tower of defense game. So I applied fixed time to path modifier in that enemy complete their path. Like following code describe. new PathModifier(speed, path); Here speed define the time to complete the path. But in tower of defense game my problem is, there is a tower which slow down the movement of the enemy. In that particular situation I was stuck. please someone provide me some guidance what to do in this situation. EDIT : Path path = new Path(wayPointList.size()); for (int j = 0; j < wayPointList.size(); j++) { Point point = grid.getCellPoint(wayPointList.get(j).getRow(), wayPointList.get(j).getCol()); path.to(point.x, point.y); }

  • Where does a "Technical Programmer" fit in, and what does the title mean? [closed]

    - by Mike E
    Was: "What is a 'Technical Programmer'"? I've noticed in job posting boards a few postings, all from European companies in the games industry, for a "Technical Programmer". The job description was similar, having to do with tools development, 3d graphics programming, etc. It seems to be somewhere between a Technical Artist who's more technical than artist or who can code, and a Technical Director but perhaps without the seniority/experience. Information elsewhere on the position is sparse. The title seems redundant and I haven't seen any American companies post jobs by that name, exactly. One example is this job posting on gamedev.net which isn't exactly thorough. In case the link dies: Subject: Technical Programmer Frictional Games, the creators of Amnesia: The Dark Descent and the Penumbra series, are looking for a talented programmer to join the company! You will be working for a small team with a big focus on finding new and innovating solutions. We want you who are not afraid to explore uncharted territory and constantly learn new things. Self-discipline and independence are also important traits as all work will be done from home. Some the things you will work with include: 3D math, rendering, shaders and everything else related. Console development (most likely Xbox 360). Hardware implementations (support for motion controls, etc). All coding is in C++, so great skills in that is imperative. Revised Summarised Question: So, where does a programmer of this nature fit in to software development team? If I had these on my team, what tasks am I expecting them to complete? Can I ask one to build a new level editor, or optimize the rendering engine? It doesn't seem to be a "tools programmer" which focuses on producing artist tools, often in high-level languages like C#, Python, or Java. Nor does it seem to be working directly on the engine, nor a graphics programmer, as such. Yet, a strong C++ requirement, which was mirrored in other postings besides this one I quoted. Edited To Add As far as it being a low-level programmer, I had considered that but lacking from the posting was a requirement of Assembly. Instead, they tend to require familiarity with higher-level hardware APIs such as DirectX, or DirectInput. I wasn't fully clear in my original post. I think, however, that Mathew Foscarini has it right in his answer, so barring someone who definitely works with or as a "Technical Programmer" stepping in to provide a clearer explanation, I'll go with that. A generalist, which also fits the description of a more-technical-than-artist TA.

  • assistance recovering/reinstalling/installing ubuntu and win7

    - by razzrat
    New computer with Windows 7 installed, I defrag, shrink, re-boot from Ubuntu LiveUSB, go to gparted and look at partitions before installing Ubuntu....for some reason Win7 is still taking up 400G of my HD! I resized partition down with gparted, exit and yes of course I can't boot into Windows. When I go to install Ubuntu in new large unallocated space I get a blank screen at the point you are asked what kind of installation you want. I have Ubuntu 12.04 LiveUSB, Windows 7 re-installation disk and driver disks also. The HDD currently has 3 allocated partitions: 'diag' fat16, 'recovery' ntfs and 'OS' ntfs which has a red '!' next to it.

  • Writing a dynamic achievement system without hardcoding rules into the application

    - by imaginative
    I really enjoyed the solution provided here for groundwork on writing an achievement framework. The problem I have is I have game designers that would like to be able to insert achievements into a CMS at runtime. In a way, it sounds insane and complex to do this, but is it really? I think the concept of having to do a hard push of the application for every new achievement is cumbersome. I would love to be able to give our designers the capability to put together new achievements by entering them into a database. It shouldn't matter what tool I'm using, but for those interested, my backend is being written in JRuby (Ruby on top of the JVM). What are some possible ways of going about abstracting the logic in the aforementioned link even further so that rules can be interpreted at runtime?

  • ManagementObjectSearcher error [migrated]

    - by Piotrek
    Some of our customers inform us that in some cases following error appears: System.Management.ManagementException: Blad dostawcy. at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() The error is generated while trying to loop through a colection returned by Get() method of the System.Mamangment.ManagementObjectSearcher object. This is the code of my method: private bool PrinterExists(string printerName) { bool retVal = false; SelectQuery q = new SelectQuery("select caption from win32_printer"); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(q)) { foreach (ManagementObject printer in searcher.Get()) { if(printer["Caption"].ToString() == printerName) { retVal = true; break; } } } return retVal; } It seems that the problem appears only on Windows XP. The only workaround I know is reconstruction of WMI database. It sometimes helps, but unfortunatelly not always. Can anyone tell me what is the reason of this error and how can I fix it?

  • Classifieds web app / eBay clone

    - by Steve
    I'm reluctant to ask this, as it may not pass the question requirements (not allowed to ask for suggestions?). Our company operates in a niche which hires and sells equipment. Often there is a requirement to source new goods, which would then be hired or on-sold. The industry (niche) as a whole does not really have anywhere specific online to go to find new goods. We thought about building a niche equivalent of eBay. To build a clone of eBay, would a simple classifieds script be too simple? We would need the majority of features that eBay has. Any suggestions for a web app to act as an equivalent of eBay?

  • Ubuntu One not syncing fully

    - by wurlyfan
    I have uploaded several folders of data to Ubuntu One from my desktop computer, over the last few weeks, and I can see that all the contents are there when I look at my account on the web. When I look at my laptop (connected to the same account), one of the first folders I uploaded hasn't downloaded completely. New folders added from either device seem to sync correctly, but this one older folder remains almost empty, even though the control panel says file syncing is up-to-date. I have plenty of space available. Stopping and restarting the sync daemon and rebooting the laptop are both ineffective. What can I do to make this folder sync fully? I don't want to risk losing the data (which now exists only in Ubuntu One), and I don't have a lot of broadband data to play with. I've seen several bugs relating to this sort of issue but they're all quite old and apparently fixed, while this is happening on new 13.04 installations on both desktop and laptop.

  • Make Sprite Jump Upon a Platform

    - by Geore Shg
    I have been struggling to make a game like Doodle Jump where the sprite jumps on a platform. So how do you make a sprite jump upon platforms in XNA? Th platforms are represented by a list of positions like Public platformList As List(Of Vector2) This is the collision detection under update() Dim mainSpriteRect As Rectangle = New Rectangle(CInt(mainSprite.Position.X), CInt(mainSprite.Position.Y), mainSprite.texture.Width, mainSprite.texture.Height) 'a node is simply a class with the texture and position' For Each _node As Node In _gameMap.nodeList Dim blockRect As Rectangle = New Rectangle(CInt(_node.Position.X), CInt(_node.Position.Y), _BlocksTexture.Width, _BlocksTexture.Height) If mainSpriteRect.Intersects(blockRect) Then 'what should I do here? For example velocity and position?' End If If (_node.Position.Y > 800) Then nodeList.Remove(_node) End If Next

  • Cloud Computing in words of one syllable

    - by harry.foxwell(at)oracle.com
    A colleague of mine challenged me to describe Cloud Computing in words of one syllable so that even his 80-year-old mother-in-law could understand the concept.  Hmmmm...The Cloud lets you do all your work on the Web or on your own net. It lets you set up your own work; no one has to set it up for you.  When you need more disk space, the cloud makes it for you.  When you need more speed, the cloud adds more gear to make your jobs go fast.  You share the cloud with more than just your own work, and you just pay for what you use.  The cloud is not new; this type of work has been done for years; just the word is new.  Now you know what the cloud is.  Or not.

  • WPF Release History : Q2 2010 Beta (version 2010.1.0609)

    Q2 2010 Beta New Controls: RadTreeListView As you have probably already noticed we started a major new initiative for completely re-writing the TreeListView control. Our first attempt (back in 2009) proved that our users are mostly interested in a TreeListView control that is based on the GridView control rather then the TreeView. Therefore, we decided to completely rebuild the control and the result is that the TreeListView now combines the powerful data-driven features from RadGridView with...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Which folders need to be backedup for migration in Joomla?

    - by Devdatta Tengshe
    I have never used Joomla before, so this might be a noobish question. I have tried searching, but haven't found anything relevant. I'm helping someone update & migrate their old website, built on the Joomla framework. Currently it is running on Joomla 1.5.8 which is an ancient version. I've convinced them to upgrade Joomla to atleast 2.5 I have already taken the database backup. Most links I have seen talk of backing up the entire public_html folder (The website runs on a shared host). But in my fresh Joomla installation there are several folders that are in the public_html folder. So which of the folders in the public_html folder are from the content of the website, and which are of the old Joomla framework? I'm afraid that I might overwrite files of the new Joomla framework with the old framework, if copy all the files and folders into the new installation.

  • Ubuntu 11.10 to 12.04 results in loss of N network capability - how to restore?

    - by user74273
    On Ubuntu 11.10, I had zero issues with N network detection and speed. I cannot remember whether the old driver was iwlagn or iwlwifi. This was with Ubuntu repository Linux kernel 3.0.0-22. Upon upgrading to Ubuntu 12.04, iwlwifi is the available driver and while it detects N networks, upon connection, the speed is cripplingly low and DNS look-ups do not occur (impossible to browse). This is with Ubuntu repository Linux kernel 3.2.0-26. Please note that the 11n_disable flag for the iwlwifi module cannot work for me as I require N network access. Is there another solution? Perhaps, is there a way to easily patch the new kernel with the old wireless module (just copy-and-paste the iwlagn module into the new kernel source and re-compile)? Relevant hardware specs: Dell Inspiron N5110 Network Adapter: Intel® Centrino® Wireless-N 1030

  • Passing class names or objects?

    - by nischayn22
    I have a switch statement switch ( $id ) { case 'abc': return 'Animal'; case 'xyz': return 'Human'; //many more } I am returning class names,and use them to call some of their static functions using call_user_func(). Instead I can also create a object of that class, return that and then call the static function from that object as $object::method($param) switch ( $id ) { case 'abc': return new Animal; case 'xyz': return new Human; //many more } Which way is efficient? To make this question broader : I have classes that have mostly all static methods right now, putting them into classes is kind of a grouping idea here (for example the DB table structure of Animal is given by class Animal and so for Human class). I need to access many functions from these classes so the switch needs to give me access to the class
