思路:设置一个条件(rotatectrl)，满足条件(rotatectrl==true)时，运动开始，否则运动终止。用一个按钮控制条件为true和false即可。其实可以不用按钮，用按键替代也是可以的。 var rotatectrl:boolean=true; function onGUI() { if(GUI.Button(Rect(Screen.width-84,Screen.height-32,40,30),"按钮名称")) rotatectrl=!rotatectrl; } function Update() { if (rotatectrl) transform.Rotate(0,Time.deltaTime*5, 0); }
