上次 我们告诉编辑器制作，如何将图像加载到现场，如今 我们要告诉下。怎么样 制造UIButton以及UIimage交换。
阿土。
进入专题。
首先，我们要明白 unity机制。button属性等。
首先 我们先说下 unity的机制：
unity中检測点击事件，使用NGUI的可能知道，NGUI使用的就是SendMessage的方式来进行事件的传递。
没错，这也是 unity最为简便的方式。
（要注意一个问题哦，这个方式 假设 你要使用 大于 万次循环的话 会有延迟的哦,一般也不会同一时候发送万条事件的）。
我们知道了 事件的传送的方式，那么我们就開始制作这个规则。首先 要使用SendMessage的话我们要拿到gameobject的对象才干使用。
所以我们要想办法拿到点击的那个物体。怎么坐那，原理事实上非常easy，就是射线。
我们都知道，unity的射线是用来探測使用的 正好。我们全部能够看到的物体都是存在camera以下，那么我们就能够使用，从camera上发射射线，来达到检測物体的作用，物体要有碰撞体哦。
先贴部分代码等这个章节完了我会贴完整的代码

这些是camera的部分，另一点这个 我们没有贴我的适配方案 摄像机的适配方案。这里统配是1420*800的设计方案。由于这里我预计还要改下，发现这个摄像机适配方案，超出了unity的物理引擎的范围。不建议。只是能够參考。
public void initVKCamere(){
gameObject.name = "VKCamere";
this.camera.orthographic = true;
this.camera.backgroundColor = Color.black;
this.camera.nearClipPlane = 0;
this.camera.farClipPlane = 9999;
this.camera.orthographic =true;
this.camera.orthographicSize = getCameraSize ();
this.transform.position = new Vector3(0,0,-1000);
this.transform.rotation = Quaternion.Euler(Vector3.zero);
this.transform.localScale = Vector3.one;
Application.targetFrameRate=60;
if(GetComponent<AudioListener>()){
//DestroyImmediate(GetComponent<AudioListener>());
}
}
int getCameraSize(){
int size = 384;
bool isLandscape=(Camera.main.pixelWidth>Camera.main.pixelHeight);
float rad = Camera.main.pixelWidth/Camera.main.pixelHeight;
bool isIPad= (Mathf.Abs(rad-1.3333f)<0.001f) || (Mathf.Abs(rad-0.75f)<0.001f);
if(isIPad){
if(isLandscape){
size=400;
}else{
size=533;
}
}else{
if(isLandscape){
size=400;
}else{
//iPhone 5
if(Camera.main.pixelHeight/Camera.main.pixelWidth>1.6){
size=710;
}else{
size=600;
}
}
}
return size;
}
camera的编辑器类
using UnityEditor;
using UnityEngine;
using System.Collections; [CustomEditor(typeof(VKCamera))]
public class VKCameraEditor : Editor { public override void OnInspectorGUI (){ base.OnInspectorGUI();
VKCamera vkCamere = (VKCamera)target; if(GUILayout.Button("ReSetCamera")){
vkCamere.initVKCamere();
}
EditorUtility.SetDirty(vkCamere);
EditorUtility.UnloadUnusedAssets();
} }
好以下我们来讲述下，button的一些东西，事实上就非常easy了。
仅仅是在编辑器方面可能会有些麻烦。
说白了 就是button就来处理 摄像机发来的东西。
尽管非常easy的一句话。但我们写得东西还是有非常多的。
依旧，button还是继承前面的view

以下就是button的编辑器方面了。
ok，这里可能有点麻烦。
只是还是能够解决的。
首先我们要获取脚本里面的方法怎么获取那。依据c#的MSDN的描写叙述我们能够看到。就是下面方法。这就是 为什么 NGUI 仅仅能找到public属性的方法。
using UnityEngine;
using System.Collections;
using System.Reflection; public class GetPublic : MonoBehaviour { static public MethodInfo[] GetObjectMethods(string selectedObjClass){
if(selectedObjClass==null)return null;
MethodInfo[] methodInfos=null;
if(System.Type.GetType(selectedObjClass)==null){
return methodInfos;
}
methodInfos = System.Type.GetType(selectedObjClass).GetMethods(BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly);
return methodInfos;
} }
这里就是button编辑器的一些属性的传递，和界面的改动哈。

我在这里扩展一些功能。像移动啊。什么。
。其实还可以添加一些功能 。这里只是学习。
有兴趣的东西可以添加你自己。
