Is it even possible to convert Sketchup files to a .dts?
EDIT: If someone manages to do this for you, I suggest a Rocket Launcher that takes at least a second to wind up before firing a Rocket.
One second= 35 damage, Projectile moves at normal speed.
Three seconds= 70 damage, Fast projectile.
An animation where parts of it spin for the wind-up would be cool.
