自定义，改变鼠标样式，光标样式

把这个脚本附在摄像机上，只要在my cursor付上鼠标的图片，my click cursor附上鼠标点击的图片就行了

#pragma strict

var myCursor : Texture2D;

var myClickCursor : Texture2D;

var cursorWidth : float;

var cursorHeight : float;

private var isClicked : boolean = false;

function Start () {

Screen.showCursor = false;

}

function Update () {

if (Input.GetMouseButton(0)) 

isClicked = true;

else

isClicked = false;

}

function OnGUI () {

var mousePos = Input.mousePosition;

GUI.depth = 0.2f;

if (isClicked)

GUI.DrawTexture(Rect(mousePos.x - cursorWidth / 2, Screen.height - mousePos.y - cursorHeight / 2,

cursorWidth, cursorHeight), myClickCursor);

else

GUI.DrawTexture(Rect(mousePos.x - cursorWidth / 2, Screen.height - mousePos.y - cursorHeight / 2,

cursorWidth, cursorHeight), myCursor);

}
