manual picture p.18 question

Post by STTrife »

Hi There,

In the manual there is this diagram about which collision shape to choose (p.18). Now I want to place a collision box in my world, which will only be used for a raycast (it's an UI thing for 3d building) I will use masks to make sure it doesn't collide with others. Now according to this diagram btBoxShape is only for moving object... is that really so? why? Why wouldn't I choose this shape for stationary objects like a wall or in my case a box that is used for raycasting?

And regarding my situation: can I just create a btCollisionShape for the ray-cast only box? or would ghost object be better, and why?

thanks a lot!

Bram
