Returns a sine value that fluctuates based on CurTime. The value returned will be between the start value plus/minus the range value.
The range arguments don't work as intended. The existing (bugged) behavior is documented below.
The frequency of fluctuation, in hertz
The center value of the sine wave.
This argument's distance from origin defines the size of the full range of the sine wave. For example, if origin is 3 and max is 5, then the full range of the sine wave is 5-3 = 2. 3 is the center point of the sine wave, so the sine wave will range between 2 and 4.
Offset variable that doesn't affect the rate of change, but causes the returned value to be offset by time
