unity3D台球游戏之球杆控制程序

会飞的鱼

看看代码效果：当点击鼠标时，球杆围绕着球旋转。
var mouseOverColor = Color.blue;//声明变量为蓝色


private var originalColor : Color;//声明变量存储本来颜色


var other:Transform;


var system:Transform;


var gan:GameObject;


function Start () {


    originalColor = renderer.sharedMaterial.color;//开始时得到物体本来着色


}


function OnMouseExit () {


    renderer.material.color = originalColor;//当鼠标滑出时恢复物体本来颜色


}


function OnMouseEnter(){


    renderer.material.color = mouseOverColor;//当鼠标滑过时改变物体颜色为蓝色


}


function FixedUpdate() {   


    if(Input.GetMouseButton(0)){


    var screenSpace = Camera.main.WorldToScreenPoint(transform.position);//三维物体坐标转屏幕坐标


    var screenother = Camera.main.WorldToScreenPoint(other.transform.position);


    var A:Vector3= screenSpace-screenother;


    var B:Vector3=Input.mousePosition-screenSpace;


    var A1:Vector3=Camera.main.ScreenToWorldPoint(A); //将屏幕坐标转为三维坐标


    var B1:Vector3=Camera.main.ScreenToWorldPoint(B);


    var angle:float=Vector3.Angle(A1,B1);


    system.transform.RotateAround(transform.position,Vector3(0,1,0),angle*0.2);


    }


   }
