Hi,

how do i stop an animation from looping?.

what i mean is ... i have a .act which is an animated safe
i set up a staticentityproxy and set the szactorfile to safe.act
then set szimpactaction to open.... which is the animation name

when i collide with the safe the door opens o.k .. but the animation
keeps on looping.
do i need a script to stop this?.

thanks ..
dodger.
