Declaration
public static float PingPong(float t, float length);
Description
PingPong returns a value that increments and decrements between zero and the length. It follows the triangle wave formula where the bottom is set to zero and the peak is set to length.
PingPong requires the value t to be a self-incrementing value. For example, Time.time and Time.unscaledTime.
The example below shows a simple use case with the light intensity going from 0 to 8 to 0 continuously.
The example below shows some outputs as example.
