GE PHYSICS FAQ

1. How can you detect collision in a game?
2. How can I change the gravity in a game?

• At the moment, the GE doesn't provide build in support fot Level of Detail. Some have coded their own LOD systems with python.

• You can optimize the peformance of you game by reducing the amount of polygons in your levels, using less logic bricks, avoiding animated models with high polygon count and avoiding python scripts that perform tens of thousands of calculations every time they run.

• There is no restriction on the poly count per scene. But keep in mind that it depends on your hardware how fast the polygons are rendered. The more polygons you have, the lower fps you will get.

• Currently there is no built in particle system in the GE, but you can fake particles by using the Edit Object actuator to spawn sprites.
