I'm trying to create a game that simulate a weighing balance. First I tried using the Physics behavior, but I gave up because I did not know how to adjust parts of the weighing balance (bar, plates, base, etc.). I am now using the Rotate behavior to simulate this and I need to compare the angle to stop the rotation (speed = 0). This action does not exist for the object, so I decided to use the system action: "compare two values". However, it did not work. Any help? Thanks.
