public static method PingPong(t: float, length: float): float;
public static float PingPong(float t, float length);


PingPong returns a value that will increment and decrement between the value 0 and length.

PingPong requires the value t to be a self-incrementing value, for example Time.time, and Time.unscaledTime.

#pragma strict
public class PingPongExample extends MonoBehaviour {
	var myLight: Light;
	function Start() {
		myLight = GetComponent.<Light>();
	function Update() {
		myLight.intensity = Mathf.PingPong(Time.time, 8);
using UnityEngine;

public class PingPongExample : MonoBehaviour { Light myLight;

void Start() { myLight = GetComponent<Light>(); }

void Update() { myLight.intensity = Mathf.PingPong(Time.time, 8); } }
