[unity3d]自定义鼠标指针

思路：使用Screen.showCursor = false; 将鼠标光标隐藏。然后用其它图片根随鼠标移动，模拟鼠标指针。

参考代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

var myCursor: Texture2D ; var cursorSizeX: int = 32 ;    // set to width of your cursor texture var cursorSizeY: int = 32 ;    // set to height of your cursor texture var condition = true ;   function OnMouseEnter ( ) {      condition = false ;      Screen . showCursor = false ; }   function OnMouseExit ( ) {      condition = true ;      Screen . showCursor = true ; }   function OnGUI ( ) {      if ( ! condition ) {        GUI . DrawTexture ( Rect ( Input . mousePosition . x - cursorSizeX / 2 + cursorSizeX / 2 , ( Screen . height - Input . mousePosition . y ) - cursorSizeY / 2 + cursorSizeY / 2 , cursorSizeX , cursorSizeY ) , myCursor ) ;      } }
