Describe the problem: When I hit D key on my keyboard, the player moved to the right side. I hit the spacebar to jump then held the D key so my player stick to the right side of the platform. How can I stop this? (make the player fall off).

CodePudding user response：

It seems to me like the player collider is getting stuck with the tilemap collider, you can create a new physics material 2D (Assets > Create > 2D > Physics Material 2D) and set the friction to 0

Then you need to assign the material to the Rigid Body of the player, how many colliders do you have on the player?
