How to optimize my applet?

Question

There is the code of my applet in the bottom. To run it you will need bob2.tga file. You can download it from http://maximusheroes.narod.ru/bob2.tga. FPS on my computer is 60. Strange thing when I comment (remove) code between "///1" and "///2" FPS is about 30. Can you please advice how to optimize the applet?

Answer 1

Please do not understand me wrong, but oh man this code is ugly!
Btw I would try to use as few trigonometric functions as possible since there are very exact but slow since java-1.4. Maybe you find more dirty trigonometry-packages on the net.
