The LeftSurfaceInput property determines the kind of input provided to a part’s
/BasePart/LeftSurface. This is only relevant for Motor or SteppingMotor SurfaceTypes. This property determines how
/BasePart/LeftParamB are used. For brevity, these properties will be referred to as ParamA and ParamB, respectively.
- By default, this is set to NoInput. This stops the motor altogether,
- For Constant, the motor rotates at a constant velocity equal to
- For Sin, the motor rotates at a velocity equal to
ParamA * math.sin(workspace.DistributedGameTime * ParamB). See
This code sample demonstrates how surface properties can be set using only a NormalId (Top, Front, etc). It switches a motor’s -SurfaceInput from NoInput, Constant and Sin to show how each work using -ParamA and -ParamB properties.
