A RotateP object joins two parts together and allows rotation about a set axis. The joint will attempt to rotate the two parts until a desired rotational position is reached. This object is most commonly created by the SteppingMotor SurfaceType. If created through a script, a RotateP's behavoir is still governed by the SurfaceInput of JointInstance.Part0.
The three inputs of note are as follows:
- NoInput: The joint will not rotate under its own power. It can still be rotated by external forces (such as from a character pushing one of the parts).
- Constant: The joint will rotate based on the ParamB property of JointInstance.Part0. This rotation is measured in radians per physics frame (which is approximately 1/60th of a second).
- Sin: The joint will rotate based on the ParamA and ParamB properties of JointInstance.Part0. The rotation measured in radians per physics frame is calculated by the function: RotationRate = ParamA _ sin(distributedGameTime _ ParamB). distributedGameTime is the current time of the game measured in seconds.
