Type | Description |
|---|---|
| float |
Remarks
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.
using UnityEngine;public class PingPongExample : MonoBehaviour{ Light myLight; void Start() { myLight = GetComponent<Light>(); } void Update() { myLight.intensity = Mathf.PingPong(Time.time, 8); }}
The example below shows some outputs as example.
using UnityEngine;public class OutputExample : MonoBehaviour{ void Start() { // Prints 2 Debug.Log(Mathf.PingPong(2, 5)); // Prints 3 Debug.Log(Mathf.PingPong(7, 5)); // Prints 1 Debug.Log(Mathf.PingPong(11, 5)); }}
