Pretty much what the title says, Is there a way to turn on and off collisions for an object via script? For an actor there is setGhost() but I don't see anything similar for an object.

SetMotionType(Motion_Keyframed)

no collision, no havok physics

Hmmm, that was exactly what I was using, however the object still collides with the player. It probably doesn't collide with other objects though, haven't tested that.

I have used Motion_Keyframed to disable Havok, but my objects still have collision.

really?

it might be because i always use translatetoref after motion keyframed

translateto and translatetoref will 100% guaranteed turn off collision (at least while it is in motion, i dont remember if it stays that way)

Yeah, I am using translateTo and translateToRef and it turns off collisions when going through stuff like walls or other objects, however when the items hits the player it pushes him back. And once translation is done the object becomes a barrier to the player unless havoc is turned back on.
