how do I change the pysics in game

How do i change the pysics of an objekt in game?
for example: I need the pysics of an cube to swift from “static” to “No collision”

i not think which you can (should be a good things)

you can change only the “state” of dynamic object , but not sure if this make advantage as performances


there also the actuators ->edit object ->Dynamics

maybe with python, but i am not sure.
but you could try to replace the mesh with a “mesh” that has no vertex.

cool , never tried but this sound as a good idea (using a mesh without vertex)
