Hello
I know that a RaycastHit function works on primitive or mesh colliders but is it possible to use it on a wheelcollider ?
Thanks
No, it doesn’t work.
A WheelCollider uses a ray cast on each frame for detecting the contact point. This is the vertical line of the gizmo at the Editor. The circle is just a representation of the WheelCollider’s radius and doesn’t have any effect on the physics.
As the WheelCollider isn’t really a “collider” as the others (it just performs a ray cast on each physical frame) then the RaycastHit function cannot hit it.
