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

Ray cameraRay;	RaycastHit hit;	Vector3 touchPos,pressOffSet;	public static GameObject touchObj = null;	public static VKCamera shareVkCamera;

void Update () {	#if UNITY_EDITOR		if(Input.GetMouseButtonDown(0)){			onPressDown(Input.mousePosition);			}else if(Input.GetMouseButtonUp(0)){			onPressUp(Input.mousePosition);		}else if(Input.GetMouseButton(0)){			onDrag(Input.mousePosition);		}	#endif	#if UNITY_IPHONE || UNITY_ANDROID		Touch touch;		if(Input.touchCount==1){			touch = Input.GetTouch (0);			switch(touch.phase){			case TouchPhase.Began:				onPressDown(touch.position);				break;			case TouchPhase.Moved:				onPressUp(touch.position);				break;			case TouchPhase.Ended:			case TouchPhase.Canceled:				onDrag(touch.position);				break;			}		}	#else		if(Input.GetMouseButtonDown(0)){			onPressDown(Input.mousePosition);			}else if(Input.GetMouseButtonUp(0)){			onPressUp(Input.mousePosition);		}else if(Input.GetMouseButton(0)){			onDrag(Input.mousePosition);		}	#endif	}

public void onPressDown(Vector2 vec){		touchPos = vec;		for(int i=0 ; i
     
      ()){					touchPos = Camera.allCameras[i].ScreenToWorldPoint(touchPos);					pressOffSet =touchObj.transform.position-touchPos;					VKButton button = touchObj.GetComponent
      
       ();					if(!iSNull(button.pressEventName) && button.eventObj!=null)						button.eventObj.SendMessage(button.pressEventName,button);					if(button.pressButtonTex!=null){						button.renderer.sharedMaterial.mainTexture = button.pressButtonTex;					}					if(button.isDrag && !iSNull(button.dragStartEventName)){						button.eventObj.SendMessage(button.dragStartEventName,vec);					}					if(button.isAni){						button.SendMessage("onPressAni");					}				}			}		}	}
      
     

public void onPressUp(Vector2 vec){		if(touchObj!=null){			VKButton button = touchObj.GetComponent
     
      ();			if(button!=null){				if(button.buttonTex!=null){					touchObj.renderer.sharedMaterial.mainTexture = 	touchObj.GetComponent
      
       ().buttonTex;				}				if(!iSNull(button.clickEventName) && button.eventObj!=null){					button.eventObj.SendMessage(button.clickEventName,button);				}				if(button.isDrag && !iSNull(button.dragEndEventName)){					button.SendMessage(button.dragEndEventName,vec);				}				if(button.isAni){					button.SendMessage("onClickAni");				}			}			touchObj = null;		}	}
      
     

public void onDrag(Vector2 vec){		if(touchObj!=null){			VKButton button = touchObj.GetComponent
     
      ();			if(button!=null && button.isDrag){				for(int i= 0;i
     

bool iSNull(string eventName){		bool buttonIsNull = false;		if(eventName== null || eventName.Equals("null")){			buttonIsNull  =true;		}		return buttonIsNull;	}

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
     
      ()){			//DestroyImmediate(GetComponent
      
       ());		}	}	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

using UnityEngine;using System.Collections;using Holoville.HOTween;//[RequireComponent(typeof(BoxCollider))]public class VKButton : VKView {	[HideInInspector] public Material buttonDefultMat;	[HideInInspector] public Mesh buttonDefultMesh;	[HideInInspector] public Texture buttonTex,pressButtonTex;	[HideInInspector] public string pressEventName = null;	[HideInInspector] public string clickEventName = null;	[HideInInspector] public string dragStartEventName = null;	[HideInInspector] public string dragEventName = null;	[HideInInspector] public string dragEndEventName = null;	[HideInInspector] public GameObject eventObj = null;	[HideInInspector] public string eventScript = null;	[HideInInspector] public bool isDrag = false;	[HideInInspector] public float scale = 1;	[HideInInspector] public string info= null;	[HideInInspector] public string[] animatorType = new string[]{"null","bigger","smaller","moveLeft","moveRight"};	[HideInInspector] public int currentAnimator = 0;	[HideInInspector] public bool isAni = false;	void Start () {		buttonDefultMat = new Material(Shader.Find("VK/VKButtonShader"));		gameObject.GetComponent
     
       ().material = buttonDefultMat;		buttonDefultMesh = new Mesh ();		gameObject.GetComponent
      
        ().mesh = buttonDefultMesh;		if(GetComponent
       
        ()== null)			gameObject.AddComponent
        
         ();		updateButton();	}	public float setScale{		set{			scale = value;			}get{			return scale;		}	}	public void updateButton(){		if(buttonTex!=null){			if(buttonDefultMat!=null)				buttonDefultMat.mainTexture = buttonTex;			if(buttonDefultMesh!=null)				buttonDefultMesh.vertices = InitBase.initVertice(buttonTex.width *scale,buttonTex.height*scale,ancPointx,ancPointy);			if(this!=null&&gameObject.GetComponent
         
          ()!=null){				gameObject.GetComponent
          
           ().size = new Vector3(buttonTex.width*scale,buttonTex.height*scale,0); } }else{ if(buttonDefultMat!=null) buttonDefultMat.mainTexture = null; if(buttonDefultMesh!=null) buttonDefultMesh.vertices = InitBase.initVertice(width*scale,height*scale,ancPointx,ancPointy); gameObject.GetComponent
           
            ().size = new Vector3(width,height,0); } if(buttonDefultMesh!= null){ buttonDefultMesh.triangles = InitBase.initTri (); buttonDefultMesh.normals = InitBase.initNormal(); buttonDefultMesh.uv = InitBase.initUV(); } } Vector3 pressScale= Vector3.zero; Vector3 pressPos = Vector3.zero; Tweener tw = null; void onPressAni(){ if(tw!=null && !tw.isComplete){ return; } pressScale = transform.localScale; pressPos = transform.position; switch(currentAnimator){ case 1: tw = VKAnimator.scaleBy(gameObject,0.3f,Vector3.one*0.2f,VkAniDuration.AnimationCurve,null); break; case 2: tw = VKAnimator.scaleBy(gameObject,0.3f,Vector3.one*-0.2f,VkAniDuration.AnimationCurve,null); break; case 3: tw = VKAnimator.moveBy(gameObject,0.3f,new Vector3(-10f,0,0),false,VkAniDuration.AnimationCurve,null); break; case 4: tw = VKAnimator.moveBy(gameObject,0.3f,new Vector3(10f,0,0),false,VkAniDuration.AnimationCurve,null); break; } } void onClickAni(){ if(currentAnimator == 1 || currentAnimator==2){ VKAnimator.scaleTo(gameObject,0.3f,pressScale,VkAniDuration.AnimationCurve,null); } else if(currentAnimator == 3 || currentAnimator==4){ VKAnimator.moveTo(gameObject,0.3f,pressPos,false,VkAniDuration.AnimationCurve,null); } } public void switchImageView(){ VKImageView imgView = gameObject.AddComponent
            
              (); imgView.imgViewTex = buttonTex; imgView.highLightedTex = pressButtonTex; imgView.ancPointx = ancPointx; imgView.ancPointy = ancPointy; imgView.scale = scale; imgView.updateImageView (); if(GetComponent
             
              ()){ DestroyImmediate(GetComponent
              
               ()); } DestroyImmediate (GetComponent
               
                ()); }}
               
              
             
            
           
          
         
        
       
      
     

这里有个 动画效果 我是自己使用的hotween整合的一些东西，假设你想用自己的能够自己去做。hotween插件 我就不用发布了，能够去官网进行下载，各大论坛也有下载资源。

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。

using UnityEngine;using System.Collections;using UnityEditor;using System.Reflection;[CustomEditor(typeof(VKButton))]public class VKButtonEditor : Editor {	public override void OnInspectorGUI ()	{		int pressEventNum= 0;		int selectScriptNum = 0;		int clickEventNum = 0;		int dragStartEveNum = 0;		int dragEveNum = 0;		int dragEndEveNum = 0;		VKButton button = (VKButton)target;		button.buttonTex = EditorGUILayout.ObjectField ("Texture",button.buttonTex,typeof(Texture),true)as Texture;		button.pressButtonTex = EditorGUILayout.ObjectField ("PressButtonTex",button.pressButtonTex,typeof(Texture),true)as Texture;		button.eventObj = EditorGUILayout.ObjectField("eventObj",button.eventObj,typeof(GameObject),true) as GameObject;				button.info = EditorGUILayout.TextField("info",button.info);		button.ancPointx = EditorGUILayout.Slider("AnchorX",button.ancPointx,0.0f,1.0f);		button.ancPointy = EditorGUILayout.Slider("AnchorY",button.ancPointy,0.0f,1.0f);		if(button.buttonTex == null){			button.width=EditorGUILayout.IntField("Width",button.width);			button.height=EditorGUILayout.IntField("Height",button.height);		}		GUILayout.BeginHorizontal();		if(GUILayout.Button("2X")){			button.setScale = 0.5f;		}		if(GUILayout.Button("1X")){			button.setScale = 1f;		}		if(GUILayout.Button("1.5X")){			button.setScale = 0.75f;		}		GUILayout.EndHorizontal();		GUILayout.BeginHorizontal();		if(GUILayout.Button("ChangeName")){			if(button.buttonTex!=null){				button.name = button.buttonTex.name;			}		}		if(GUILayout.Button("Switch ImageView")){			button.switchImageView();		}		GUILayout.EndHorizontal();		if(button.eventObj!=null){			MonoBehaviour[]	monoScriptArry =new MonoBehaviour[button.eventObj.GetComponents
     
      ().Length+1];// button.eventObj.GetComponents
      
       ();			for(int i=0;i
       
        ()[i];				if(i == monoScriptArry.Length-1){					monoScriptArry [i] = null;				}			}			if(monoScriptArry !=null&& monoScriptArry.Length>0){				string [] scriptName = new string[monoScriptArry.Length];				for(int i=0;i
        
         0){					string[] methodArry = new string[publicMethodArry.Length];					for(int i=0;i
        
       
      
     

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。
