• JUNJIE.HONG Interfaces

  Could anyone point me in the right direction regarding programming c# with interfaces. I've googled up the subject and whilst there are some good tutorials on how to do it, non of them really explain in simple terms why we should or shouldn't. I just can't seem to get my head around how they work properly. You often use interfaces when a group of classes have a similar behaviour but are otherwise unrelated. Sometimes this is because they can all do a second 'trick', like generate log data, but you don't want them to all have the same base class (so it is like a cheap multiple inheritance). Another example might be when you load plugins - you could force all user created plugins to inherit from your plugin class, but that can get ugl ...Show All

• Nawar G. What are the recommended books and sites for learning C# so I can then make a game using XNA?

  XNA has made game development easy, but to use the XNA framework you still have to be able to develop with C#. You don't have to be an expert, but you do need to understand the basics of Object Oriented development and the general syntax for the C# language. That's great for those of us who are already developers, but there are a lot of people interested in XNA, that are not already developers (and some of them are developers who just haven't given C# a try yet). Every time a new game developer hopeful comes into the forums frustrated because they don't understand the code or where to start, we give them a generic answer about taking some development classes, find some books on C#, check out some C# tutorial sites or point them towards To ...Show All

• THE RAZI Any regional restriction about Creators Club membership and XNA Game Launcher

  I am an indie developer in Hong Kong. It is so exciting that XNA will be released in 11th Dec, and I decide to join the Creators Club immediately so that I can test my homebrew game on XB360 asap. But I would like to confirm that is it any problem to subscribe and execute the XNA Game Launcher on HK / JP or US XB360 You can easily move the disc of the one copy you buy between the consoles, although it can only run on one console at a time. Something similar should be the case with any digital purchase (but often is not -- hence the reluctance of consumers to move away from physical media). Also: what if my console breaks, and I get a replacement on eBay There is nothing stopping you having multip ...Show All

• XNA Rockstar Contour offset of a polygon

  Dear All, I am using DirectX to write application and I cannot figure out how to do this: I have a polygon and I want to create inward contours offset of that polygon by giving number of contours that I want and the distance from one contour to another as well. I would highly appreciate if anyone can advise me the algorithm of doing this Regards, LG Cel shading algorithms are all doing the technic you're decribing : extracting contours and rendering them with tunable parameters (thickness, ...). I won't be able to explain you how to do, but you can easily find tutorials and samples around the net. You can try Nvidia and ATI developper pages, Nehe (but it's opengl), and of course google ...Show All

• PhaedoHD Probably an easy one: I'd like a class to have its own textures.

  I'm converting over an old project I did in GSE Beta 1 where a class (specifically, my 'background image' class) had its own Texture2D. Here's exactly how I went about loading the texture in my old Beta1 version: Vector2 location, offscreen; Texture2D bg; public Background(GraphicsDevice Device) { location = new Vector2(0,0); offscreen = new Vector2(0,480); bg = Texture2D.FromFile(Device,"resources\\background.png"); } Now obviously this doesn't work any longer. As such, I've been trying to convert this over to 1.0 compliant code. I can get my code to compile without any problems, but I can't get the silly thing to run. The error I keep getting is as follows: Error loading "backg ...Show All

• meho Camera concepts

  I was reading a little bit about camera handling and was wondering what the typical concept is. Assume you are programming a 3D world where a player can move. Would you: a) move the camera and leave the world objects fixed if the player moves or b) move all world objects to make it appear as if the player moves I write something that plays in a fixed sized world and I have several elements moving independently from the player, so I used a) there. But would you use a) for e.g. a space fighter simulation, too Or a race game Or something that plays in a virtual city Hi Mr. Doe, I remember wondering about this myself, some time ago. :-) Don't sweat it. Just move your objects and camera(s) directly ( ...Show All

• Christoph_S Terrain Options

  Hi Whats better for implement terrain -Use the content pipeline for load then .x file with the terrain or -implement de class for convert the pixels of .raw file in vertex with the height (y axi) dependent of de gray color I have problem whit the first option becose a can't extract the vertexs of vertexbuffer becose the vertexbuffer is WriteOnly What I can do thank's Man. That's about five more ways than I had thought to do it. Reasonably, you could have a split that tests for Shader 3, and if not, fail back to the heightmap processing in the build. I'm pretty sure there's a tutorial on the net somewhere that covers how to do this, and I h ...Show All

• Jyothi G Video/Animation Playback

  Hi, I'm currently writing a library (for XNA/DirectX) for animation/soundless video playback, and I have a few design questions for the pros out there if you don't mind answering them : I'm having my animation class inherit from game component, and update the frame depending on game time in the overriden Update method, and render it in the overidden Draw method, but even when I preload my textures to render, playback is choppy. Not sure exactly why, but I notice this only when I have significant number of frames (I noticed it with 100 frames, but *not* with 10/15). This problem may be linked and solved by the 2nd point, so please read on. When I preload all the textures for the frames in the animation (and the no. of frames ...Show All
