Wierd issue with P3D and camera clipping?

[3 Replies]

I'm developing a small sort of FPS thingy that I hope to evolve into an actual sort of game thing, and so far i have a cube rendered on screen which the player can collide with when moving around with WASD and looking with mouse, but when the player looks at the box while colliding with it; the camera clips strangely with the geometry. What could i do to fix it?

My code:
2. import java.awt.AWTException;
3. import java.awt.Robot;
4. import java.awt.Point;
5. import java.awt.PointerInfo;
6. import java.awt.MouseInfo;
8. Robot bot;
9. PointerInfo pointer;
10. Block blocks;
11. Player player;
12. Boolean keys[] = new Boolean[526];
14. void setup(){
15. size(640,480,P3D);
16. noCursor();
17. try {
18. bot = new Robot();
19. }
20. catch (AWTException e) {
21. e.printStackTrace();
22. }
23. blocks = new Block(32,32,-16,64,64,16);
24. player = new Player(0,0,0);
25. for(int i = 0; i< keys.length; i++){
26. keys[i] = false;
27. }
28. noStroke();
29. }
31. void draw(){

EDIT: I am using Processing 1.5; the latest version seems to be missing a function concerning keyboard keys so I'm using this for now
