Hello. I would like to learn OpenGL 4 but I am pretty sure that my laptop does not support it. When I was learning DirectX 11 (which my laptop also does not support) before, there was a way to run it using software emulation. I am wondering if same also goes to OpenGL 4. If there is, how? and can you also point me to some great tutorials? Thanks!
Edit: I just checked. My laptop supports OpenGL 3.3. Do you guys think that it's better to just learn OpenGL 3.3, instead OpenGL 4?

[Javascript] Catching Keyboard Input in GameLoop
28 January 2012 - 10:04 AM
Hello guys. I'm having a problem catching a keyboard input in Javascript. I've tried this before in a different language but I can't make it work in Javascript. I am trying to catch this type of keyboard input (I don't know what it's called)
Help me find what is wrong with my implementation (Please, I've been frustrated trying to debug this for hours). TIA! Here is my code:
if(prevKeyState.isDown(Key.X) && !currentKeyState.isDown(Key.X))
