Script to round all animation keys into integers.

Hello, I am new to max script. I want to round object position and rotation keys to "integer". I am modding Tomb Raider, and animations can not use floats....

As for now, I got this little snippet from internet which sets key at every frame.

 
sTime = animationRange.start
eTime = animationRange.end
for obj in selection do (
	for t = sTime to eTime do
		addNewKey obj[3] t
)
