What is the best way to have objects that treat other objects as if they were kinematic?.

I have a platform with some blocks, and we would like the player to be able to push blocks, but not the enemies, although both use the charactercontroller. Or another example is a platform that must be unpushable until certain point.

I considered using a raycast to stop the player if it collides with it, but is there a better way?

For objects which must appear kinematic to one set of objects and dynamic to another set of objects at the same time, create a kinematic proxy for the dynamic object. Set the position, orientation, linear velocity, and angular velocity of a similarly shaped kinematic entity to that of a target dynamic entity each frame. Set up the CollisionRules such that certain objects hit the kinematic version, while other objects hit the dynamic version.

Or another example is a platform that must be unpushable until certain point.

For objects which need to behave dynamic and one time and kinematic at a different time, the entity state can be changed using the BecomeDynamic and BecomeKinematic functions.
