wrong collide result

Post by 3100889812 »

I an new to bullet and do basic test
I use a box and a sphere ,the box is moving from left to right,sphere is not moving
I change the box rigidbody world postion every frame,getWorldTransform().setOrigin()
and call contactTest everyframe,but the callback comes earlier,in fact the box and sphere not collide,just a little gap。

You're probably experiencing the collision margin of some convex-convex shape collisions. There is an old video on YouTube that illustrates margin.
