GuiManager2的用法,想让GUI旋转缩放是很简单的.doc

如要转载必须注明转帖自CocoaChina论坛。GUIManager 2是besuser发表于unity官方论坛的一个Unity插件，主要用在iPhone上。插件地址：/viewtopic.php?t=43084本站下载地址：/bbs/job.php?action-download-pid-92520-tid-15677-aid-8094.html优点：（这个东西真的很强大，直接拿它做一个游戏也不是不可能的） 支持3D旋转缩放 将描绘GUI元素缩减为1个drawcall，极大地提高效率 支持材质地图，多个GUI元素可以放到一张图片上，节省内存 GUI元素的所有属性都可以设置动画 支持逐帧角色动画 支持Touch事件 所有GUI元素都支持淡入淡出。 可以对GUI元素调色 动态缩放 GUIText和GUITexture均可集成进场景内 支持10个GUI层 支持iPhone上5个点同时触摸 同时支持Unity iPhone和Unity 可以调节GUI上的哪部分响应触摸事件 与屏幕分辨率无关，并非仅仅支持iPhone 比上一版更容易设置 完美像素元素碰撞支持，也可以支持非规则物体的触摸事件。设置方法：1 建立一个空的项目。2 把下载来的包导入到这个项目里。3 建一个空的GameObject，取名为GUI。找到PlugIns目录里面的GUIManager脚本，拽上去。然后设置屏幕的分辨率（比如480x320），如果需要iTouch支持，也同样把PlugIns目录的iTouch脚本也拽进去。4 再建立一个空的GameObject，随便取名。比如我取名叫quadmgr，拽到刚才建立的GUI下面。然后在PlugIns目录找到GuiQuadMgr这个脚本（不要看原文，他写错了），拽到刚创建的quadmgr上。拽完后，把Position和Rotation改成0 0 0，scale改成1 1 1。5 重复上面，建个空的GameObject，拽到quadmgr下面，随便取名，比如button。然后把PlugIns目录里的GUIQuadObj这个脚本拽上去。6 然后需要调整属性了：先点选回quadmgr，里面有个Material属性。如果你导入了这个插件包，里面有个默认的material，你可以用，叫TestMaterial。先用着吧。你可以看看这个TestMaterial，用的Shader是GUIManager With Backface。另外还有一个Shader叫GUIManager。这两个区别就是一个翻过来也会显示材质，另一个不会。Alloc Block Size设置为1或者以上即可。7 这里有一堆属性设置，很简单的英文，不翻译了。* MColor Set the tint and alpha for the gui object.* MWidth - The width of the gui object* MHeight - The height of the gui object* MLocation - The initial location on the screen this gui object should be at. The anchor is in the middle of the gui.* MRotation - The initial rotation of the gui object.* MScale - The initial scale of the gui object.* MUV - The lower left UV coords of the texture map to skin this gui object.* MDepth - The layer order. Larger value objects gets placed further back.* MAnimUV This is the UV coords for the first frame in a sprite animation filmstrip.* MAnimCols The number of columns for the sprite animation filmstrip.* MAnimMaxFrames The total number of frames in the sprite animation.* MCollider - You can select None, Square or Circular hit areas used for touch inputs.* MCollider Size Size of the touch area associated with this gui object.* MVisible - Is this gui object visible* MEnabled Determine if the gui object will response to inputs like the mouse or touches.8 在quadmgr选好层之后，下面所有子GUI元素都会显示在这个层上。9 在主摄像机的Culling mask里关掉创建的层（这里没搞明白，目前没影响使用）。10 创建GUI处理程序。（自带例子里用的是C#，我传的附件用的是Javascript。）把处理程序拽到子对象上（比如刚才那个button）就可以了。然后我再简单说一下处理GUI的脚本程序怎么写：下面这段代码是让图片里的那个字母“G”不停顺时针旋转。请注意看代码的注释。private var thisObj:GUIQuadObj;function Awake()thisObj=gameObject.GetComponent(typeof(GUIQuadObj); /先获取要旋转的对象，那个Gfunction ResetAnimation()thisObj.Rotation=new Vector3(0,0,0); /转完一圈之后归位接着转function Start()/类似的函数还有：AnimateTo, AnimateFrom, AnimateBythisObj.AnimateTo(3, /持续事件gameObject, /回调对象，写gameObject就可以ResetAnimation, /回调函数名null, /回调参数Rotation, /这个参数，可以是Rotation，Location，Scale等，参看上面第7条的属性名，把前面的M去掉，都可以调整new Vector3(0,0,-360),easing,Ani.AnimationEasingType.LinearEasing);/其他的easing方式还有：LinearEasing QuadraticEasing CubicEasing QuarticEasing QuinticEasing SinusoidalEasing ExponentialEasing CircularEasing BackEasing BounceEasing ElasticEasingthisObj.StartAnimation (Ani.Animate.Loop, null, null, null); /循环方式有两种：Ani.Animate.OneShot, Ani.Animate.Loop 再有就是关于Texture地图的问题。例子里面带了个图SampleMenu，刚开始使用的时候，可以直接就改它那个图，试验一下按钮或者动画怎么放。这样一来，使用GUIManager2，你所有的GUI旋转，缩放，动画之类的问题，就都解决了。GUI再也不会看起来很无聊了。附：GuiManager2类的参考：引用GUIQuadObj Class:This class handles the quad for all the GUI elements. It communicates with the GUIQuadMgr to merge all the elements into a single mesh.Parameters:- GUIQuadObj.QuadManager: Gets a pointer to the GUIQuadMgr this object is attached to.- GUIQuadObj.QuadSprite: Gets a pointer to the GUISprite class used internally.- GUIQuadObj.Tint : Set/Get the objects color.- GUIQuadObj.Width: Set/Get the objects pixel width.- GUIQuadObj.Height: Set/Get the objects pixel height.- GUIQuadObj.Location: Set/Get the objects location on the screen in pixel coordinates.- GUIQuadObj.Rotation: Set/Get the objects rotation in degrees. You can do rotation on all three axis. To get rotation with perspective, set the camera under the master GUI object to perspective. Otherwise, youll get orthographic rotations.- GUIQuadObj.Scale: Set/Get the objects scale. One unit represent on width/height value of the object.- GUIQuadObj.UV: Set/Get the UV coordinates for the lower left corner of the quad.- GUIQuadObj.Depth: Set/Get the layer depth of the object.

You must call after changing any of its parents transforms to re-sync the object with the new world coordinates. If you dont do this, the hit areas and the paint area will be in the wrong place.Callbacks/Events:- onGUIUp (iPhoneTouch pTouch)- onGUIDown (iPhoneTouch pTouch)- onGUIMoved (iPhoneTouch pTouch)GUITextObj Class:This class handles the use of the GUIText component.
