对值 t 进行循环,使它不会大于长度,并且不会小于 0。
这类似于取模运算符,但是它适用于浮点数。例如,将 3.0 用于 t
并将 2.5 用于 t
,结果是 0.5。而当 t
= 5 并且 length
= 2.5 时,结果是 0.0。但是请注意,与取模运算符一样,没有为负数定义行为。
在下面的示例中,时间值限制为介于 0.0 与恰好低于 3.0 之间。然后它用于将 x 位置保持在
此范围内。
using UnityEngine;
public class Example : MonoBehaviour { void Update() { // Set the x position to loop between 0 and 3 transform.position = new Vector3(Mathf.Repeat(Time.time, 3), transform.position.y, transform.position.z); } }
