Collision issue in Carrom

Hi guys...

I am creating a Carrom game. Every thing is fine except 1 thing. When i add force to the striker it moves into a trajectory. So it moves from over the other coins in air and goes out of the board. I want it to move straight in x and z axis, but not Y axis.

Plz help!

Just add Rigidbody component to the striker and coin, and tick the y position constraints

I have a question that which collider did you use in tokens/Slam/Coins MeshCollider or something else?
