static function PingPong (t : float, length : float) : float

Description描述

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

	// Set the x position to loop between 0 and 3
	//设置x位置循环在0和3之间
	transform.position = Vector3(
	Mathf.PingPong(Time.time, 3), transform.position.y, transform.position.z);
