is there any way to add or delete physics behavior to an object at run time.
I have like maybe 50-100 physics object . and must of them are inactive all the time. they get activated when another object overlaps them.
And if there is no way to do so, What is the maximum number of physic objects on the layer that don't affect the performance in mobile devices.
And Can I have like 100 physic object which are immovable, I just use them with another movable object like a ball.
