JavaScript => static function PingPong(t: float, length: float): float;
C# => static float PingPong(float t, float length);

Description 描述

PingPongs the value t, so that it is never larger than length and never smaller than 0.

让数值t在 0到length之间往返。t值永远不会大于length的值，也永远不会小于0。

The returned value will move back and forth between 0 and length.

返回值将在0和length之间来回移动。

JavaScript:

function Update () {
	// Set the x position to loop between 0 and 3
	transform.position = Vector3(
		Mathf.PingPong(Time.time, 3), transform.position.y, transform.position.z);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Update() {
        transform.position = new Vector3(Mathf.PingPong(Time.time, 3), transform.position.y, transform.position.z);
    }
}
