So, I've been playing around with physX for a while in a test project of mine, creating char entities with kinematic physics, rigid sphere entities, and static WMB entities.

And I've discovered, to my own dismay, that Gamestudio's implementation of PhysX sucks.

I'm sorry, it really does. Here's my biggest problems with it:

- pXent_movechar() is super inaccurate and uncontrollable. Many times an entity will stop moving before it even collides with an object, although I can get close to it anyway by sliding up against it. In addition, pXent_movechar() will cause entities to bump over and around objects, even if there's no way they can or should!

- WMB entities don't set the size of their BBoxes properly! As a test, I created a rigid, dynamic sphere body and started rolling it around on a bunch of WMB entities. To my annoyance, I found that the sphere will fall partly into a WMB entity! I know it's a problem with the WMB entity, because all other physics objects collide with the sphere normally. What's the deal?

- There's no way to control the size of an entity's BBox! seriously, pXent_setskinwidth() just doesn't work at all. In fact, it does the exact opposite of what it's supposed to do. I know, because I've tried passing it multiple different positive and negative values, fractional and non-fractional. But it doesn't work worth beans.

- With PH_CHAR and kinematic entities, boxes are treated like ellipsoids. This is exactly what I was trying to escape in the first place!

I faced all this problems a long time ago... But I though I was doing something wrong.
PhysX is implemented really badly... too many bugs, and too many little things.
But, hey, is there any sense in saying this? jcl doesn't give a s**t about our problems.
As I got banned at once for saying truth, he told me:
"Read manual and all of your bugs will flawlessly disappear."
But why even if I read manual, I can't just make another shape for BBOX (simply cause I want another shape)!
Why do I still get bugs with PhysX (jcl said that it's about year since it's implemented, year is good enough to make it stable)?

I didn't know Physix had so many bugs ???

Perhaps the best way would be a stable free physic engine by calling it's DLL and make our own implementation, behaviour ?

Strange i used Unity game engine physics character controller
and it's really fine, and works well ??

We not saying that PhysX has so many bugs! We saying that it's implementation in GS is sucks.

So why not changing the implementation in your own way
for character controller ? Or for all the physic stuff collision you need ?

C_move uses the shape of the mesh for collision detection. So your answer is to change the shape. In each of the eight corners of your mesh put a vertex there with med. Now as far as the engine is concerned you have a box.

That isn't actually how c_move works.

I haven't got to test it but I'm not sure why it would not work.

Because c_move treats each moving entity as an ellipsoid.

Yeah, c_move uses OBB collisions, which uses an ellipsoid. There was and AABB in A7, it had BOX hull, but A8 doesn't support it
