ngui处理不规则按钮点击

吐个槽  棋牌类游戏做什么中国地图！！！  然后就要用到不规则按钮点击了 你懂的 

213的unity虽然已经加入了polygoncollider 2d的支持 但是 但是 但是 是2d的 也就是说如果不把摄像机的event修改为 2d_ui 是不支持的  然后213的ngui点击事件都要依赖3d_ui

这就造成如果想同时支持规则按钮跟不规则按钮 只能使用一个2d摄像机 一个3d摄像机   还有一种办法就是增加事件类型同时处理两种情况  。。。。  就有了下面这段代码   纯抄袭 谢谢原作者 

UICameraEditor 修改

//string[] options = new string[] { "3D World", "3D UI", "2D World", "2D UI" };
string[] options = new string[] { "3D World", "3D UI", "2D World", "2D UI", "UI_2D3D" };

uicamera 增加枚举类型定义 UI_2D3D,
