目標是當按下 P 鍵時，在下一個航路點和最后一個航路點之間進行不間斷的乒乓球運動。包括當變換開始從他的原始位置移動時按下 P 鍵，所以在第一個航路點和變換原始位置之間做一個乒乓球。
現在的情況是，當我按下 P 鍵時，整個游戲都凍結了，編輯器凍結了，我需要將其關閉。

編輯 ：
這幾乎像我想要的那樣作業：
當它打乒乓球時，它在最后一個變換位置和下一個航路點位置之間進行，我希望它在最后一個航路點和下一個航路點之間。但是乒乓球現在正在作業。

uj5u.com熱心網友回復：
您的編輯器凍結，因為在pingPongEnabled設定為true您的情況下
if (pingPongEnabled)
{
transform.position = Vector3.MoveTowards(pingPongStart, WayPoints[CurrentWayPoint].transform.position, Mathf.PingPong(Time.time * 1, 1) * Time.deltaTime);
continue;
}
在回圈中沒有yielding -> 因為continue它立即進入下一次迭代，而退出條件從未滿足。
你要確保總是做
if (pingPongEnabled)
{
transform.position = Vector3.MoveTowards(pingPongStart, WayPoints[CurrentWayPoint].transform.position, Mathf.PingPong(Time.time * 1, 1) * Time.deltaTime);
yield return null;
continue;
}
為了至少等到下一次迭代的下一幀
總之這個
transform.position = Vector3.MoveTowards(pingPongStart, WayPoints[CurrentWayPoint].transform.position, Mathf.PingPong(Time.time * 1, 1) * Time.deltaTime);
并不像您可能期望的那樣真正“乒乓”。它總是從原點開始pingPongStart并朝著航路點移動一步，并且只會走得更遠或更少。
你可能寧愿
transform.position = Vector3.Lerp(pingPongStart, WayPoints[CurrentWayPoint].transform.position, Mathf.PingPong(Time.time, 1));
