unity3d简单的图片代替鼠标

var Mid:Texture2D;

var Mouse:Texture2D;//鼠标图片

var mousePos = Vector2.zero;//鼠标的位置

private var angle:float;

function Update()
{

　　mousePos = Input.mousePosition;//获取鼠标位置

　　angle = 180 – Mathf.Atan2(mousePs.x – 250, Screen.height -mousePs.y – 250) * Mathf.Rad2Deg;//计算选择角度

}

 

 

function OnGUI () {
　　 Screen.showCursor = false;
　　 GUIUtility.RotateAroundPivot (angle, Vector2(250, 250));
　　 GUI.DrawTexture(Rect(200,200,100,100),Mid);
　　 GUIUtility.RotateAroundPivot (-angle, Vector2(250, 250));
　　 GUI.DrawTexture(Rect(mousePs.x,Screen.height -mousePs.y,25,25),mouse);
