Question by THEpancakes · Oct 28, 2013 at 06:37 PM · collisionrigidbodymesh collider

Mesh collider not colliding with ball properly

Ok, so I'm making a game in which the player has to tilt a maze to guide a ball through it. I've made several different models of mazes in Sketchup, and have got a functional script to control the tilt of the maze, but the ball isn't rolling along the board correctly...

The ball is basically just a sphere with a rigidbody, the board's movement is controlled by a script, and it also has a rigidbody (kinematic) attached to it.

Whenever I tilt the maze, the ball starts rolling for a moment and then just stops, mid-board, without actually hitting anything...

Why is it doing this? Do I need to add something extra to my colliders?

I had the same problem and found the answer here on forums. What happens here is that rigid body is entering to sleeping state when not moving. To solve this add a simple script to your ball to wake it up:

 void Update () {
     
         if (rigidbody.IsSleeping())
         {
          print("Wake up");
          rigidbody.WakeUp();
           }

I am finishing similar game now if you have any general problems with physics let me know I might be able to help
