Hi, I’m trying to make lockpicking in my game. I want to make it in UI because I don’t want the lock and the pick to collide with other objects in the scene. The pick needs to collide with the pins to move them but colliders don’t collide with each other. Help me please 
You shouldn’t be using UI for physics based things. Instead, use Sprites in the world with proper rigibody/colliders and use the Layer Based Collision matrix to ensure they only can collide with each other.
