The engine framework is clearn and nice,
but the currenty object transform system(based on matrix) is diffcult for fast using,hope there will be some game class which use for Entity moving,just like blitz3d command:when you want to move a object,just
use:
Entity.setPosition(vec,local/World Space),
Entity.Move..
Entity.Rotate...

also you can check out unity3d 's transform class for really nice moving functions.

for those people who don't know much about matrix,this helps a lot!!
