I like to put a rigidbody cup on a rigidbody tray (like a moving platform). The tray is moved by mouse. If I put the cup on the tray and try to move the tray the cup always slide and not connected to the tray. The cup must slope and fall if the trays force is too high.
I tried to figure out 2D platform tutorial where the character stays on the moving platform perfectly but I have still no idea.
Do you have any idea how to solve this problem?
