I have an enemy object set as a physics object that's going up and down, and below it there is a platfrom, I don't want the enemy physics object to collide with the platform, if I change the platform to no collide then the character won't be able to walk on it, if I change the enemy object to no collide then its physics will change, how do I do this?
Add another object that's invisible with physics without any 3D worlds on top of the existing platform.
