Transform all moment applied to a body to torque

[vervatovskis]

Hi gentlemen,

I have a cpBody in a chipmunk space, I am trying since three days the to detect when moment is applied on a body and apply a force against this one, in other words I want to transform all moment applied on this body to torque I want the body to turn around it self without changing its position, For more precision thr space have a gravity. Any ideas please?
Thanks in advance.

I don't understand what you are trying to do.

It sounds like you just want to use the cpBodySetTorque() property maybe? Otherwise applying a force will always cause the body to move unless it's canceled out by another force.

Hi, Thank you for your answer, I am trying to develop a tower game, the game consist on superimposing sprites, when enough mass is above a sprite, it turn, what I want is that the sprite turn only without changing position. I hope this is better clear. Thanks

You want to use the cpBodySetTorque() function then.
