UpdateWorld:Void elapsed_time:Float32=1

Parameter	Mode	Type	Default	Description
elapsed_time	In	Float32	1	Animation speed of the whole world: 1 plays animations at their own speed, 2 at double speed, 0.5 at half. Defaults to 1.

Description

Advances the world by one step: moves animated entities on and applies the collision rules, so entities with a collision type are pushed out of the things they hit. Call it once per main loop, before RenderWorld. Without it, animations stand still and collisions never happen.
