A little question:

when I set the kinematic flag of a rigid body physics entity,
it goes straight trough walls, and the ground.
the manual says it should have collision detection, but it hasn't.
The manual example doesn't work either for me.

I have already posted posted this question, but I don't expect it to be answered there, so I posted it here

Kinematic entities are not affected by any force. So what happens when an unstoppable force hits an immovable object? They go through each other. The collision detection mentioned is collision detection with other non-kinematic physics objects -- they'll get pushed out of the way, no matter how heavy, but can't push back at all.

I hope that makes sense.

from the manual I understand that they do perform collision detection, just like ph_char and c_move

this is what I read from the manual

Kinematic entities (NX_BF_KINEMATIC) and character controllers (PH_CHAR) are moved with collision detection. Depending on friction, relative position changes must exceed a certain threshold for moving the entity. While moving, forces have no effect on them.

I could be wrong, still...
but the kinematic entities seem to even pass through level geometry

I think you're right, actually. I was thinking about the wrong thing, and then applied it to this to become even more wrong.

This might be a silly question, but did you set the level entity to a physics entity?

I don't actually know anything about using PhysX.

In the first place I tried it with static physic entities,
but the kinematic entities also fall through them.

To clarify: JulzMighty is correct. Kinematic entities do collision detection. They can push other entities out of the way. But they seem unaffected by collisions themselves. At least, that's my observation when I put an obstacle in their way.

they also aren't affected by level blocks and static entities?
then I must have read something wrong in the manual.

thanks for the answers
