Declaration

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

Description

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.

using UnityEngine;

public class PingPongExample : MonoBehaviour
{
    Light myLight;

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

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