Re: Component based entity system implementation?

I don't personally use an entity based system but here's the first approach that comes to mind. - Store a string containing the name of the component in each component class (or virtual method you can overload to return a string) - Instead of using a vector in your Entity class to hold components, u...

Re: Memory Usage Optimization

It's hard to suggest much without knowing the specifics of your game. I don't have experience with Dreamcast but I'm assuming you're currently using 32-bit textures? Try reducing to 16-bit or 8-bit palleted textures if possible. Also make sure you're freeing your local copy of image/pixel data after...

Re: Orthographic Projection Issue

What are the results if you omit using any model or camera transforms and multiply the vertices of an on-screen quad by just the ortho matrix?

Re: Fixing Bugs After Release

Have you considered using the NSError class?

Fixing Bugs After Release

I've been working on a game for the past year that I plan to release on iOS/Android. Up until this point I've neglected to do any sort of meaningful error handling. Typically, I'll simply have my functions return false on error and basically close down the app. I know if I don't take steps now to in...

Re: Orthographic Projection Issue

Try these 2 changes: void Matrix4f::InitOrthoProjTransform(float left, float right, float top, float bottom, float zNear, float zFar) { m[0][0] = 2 / (right - left); m[0][1] = 0; m[0][2] = 0; m[0][3] = 0; m[1][0] = 0; m[1][1] = 2 / (top - bottom); m[1][2] = 0; m[1][3] = 0; m[2][0] = 0; m[2][1] = 0; ...

Re: Mondo (PC, free) released: My fast-paced action-arcade g

Good work :) One thing I would suggest is to always make sure you add some design elements to your game that allow for replayability. In this case, I think you could use some simple rules to procedurally generate unique levels instead of having just a single level. Perhaps even add support for level...

Re: Reading Chess Position

Well apparently the "scanf" function just doesn't work very well with getting inputs in a loop. Ended up using "sscanf" with an input string instead. Now it works. I think the problem you're having is because scanf will just read the newline character the second time you call it...

Re: Reading Chess Position

Haven't personally used these functions but what happens if you switch it to:

sscanf_s(input.c_str(),"%c %d", &inputX, sizeof(inputX), &inputY);

Re: [Q] Getting the point of contact between 2 OBB rectangle

I actually wrote somewhat of a tutorial on the subject of building a 2D rigid body physics engine (it's not finalized). I've attached the section I wrote on finding contact points for polygon-polygon collisions, it should be of help. If you have any questions, I'll try to answer them. If it's not t...

Re: Java gaming discussion

Java is perfectly fine for game development. In my experience the main thing you need to worry about is being careful with your allocation/deallocation strategy so the garbage collector doesn't come into play and cause large delays during gameplay. Not quite sure what you were getting at with the fa...

Re: What Does This Code Do?

I looked at it again today, same issue. I'm using XCode 4.2 which uses LLVM 3.0 btw. I realize it's a C++ 0x feature, I'm just surprised at the fact that it compiles without an issue but simply does not initialize the damn strings. I'm guessing it's just a bug in this version?
