Unity3D NGUI动态创建按钮

本例仅以熟悉NGUI组件功能为目的，想快捷简便的创建按钮或其它游戏物体请参考 “Unity3D 动态实例化Prefab”

以动态创建服务器列表为例。

 

 public UIAtlas mAtlas;
     public UIFont mFont;
     public string mSriteName;
     public GameObject Playerlist;
     /// <summary>
     /// 动态加载一个NGUI按钮
     /// </summary>
     /// <param name="name"></param>
     private void CreateServerButton(string key,string name, int index)
     {
         //获得深度（要创建button的Panle的深度）
         int depth = NGUITools.CalculateNextDepth(PanleMe);
         //创建button物体,命名、设tag、摆所在panle的相对位置。
         GameObject go = NGUITools.AddChild(PanleMe);
         go.name = name;
         go.tag = "trendsButton";
         go.transform.localPosition = new Vector3(-180 + (index % 3) * 180, 140, 0);

         //添加button的背景图片UISprite
         UISprite bg = NGUITools.AddWidget<UISprite>(go);
         bg.type = UISprite.Type.Sliced;
         bg.name = "Background";
         bg.depth = depth;
         //背景图片使用的图集
         bg.atlas = mAtlas;
         //图集中使用的精灵名字
         bg.spriteName = mSriteName;
         bg.transform.localScale = new Vector3(150f, 40f, 1f);
         //跳转位置（必要）
         bg.MakePixelPerfect();

         //如果有字体，添加UILabel
         if (mFont != null)
         {
             UILabel lbl = NGUITools.AddWidget<UILabel>(go);
             lbl.font = mFont;
             lbl.text = name;
             lbl.transform.localScale = new Vector3(22f, 22f, 1f);
             lbl.transform.localPosition = new Vector3(0, 0, -1f);
             lbl.color = Color.black;
             lbl.MakePixelPerfect();
         }

         //添加碰撞（有碰撞才能接收鼠标/触摸），大小与Button背景一致
         BoxCollider box = NGUITools.AddWidgetCollider(go);
         box.center = new Vector3(0,0,-1);
         box.size = new Vector3(bg.transform.localScale.x, bg.transform.localScale.y, 0);

         //添加UIButton触发事件的必要组件，并关联之前生成的UISprite
         go.AddComponent<UIButton>().tweenTarget = bg.gameObject;
         //添加动态效果组件（大小、位移、音效）。（可选）
         go.AddComponent<UIButtonScale>();
         go.AddComponent<UIButtonOffset>();
         go.AddComponent<UIButtonSound>();

         /*------ 一下是自己要用到的UIButton功能，可以绑自己需要的组件 ------*/
         //添加一个开启Player list Panel 的按钮事件
         UIButtonTween serverListPanel = go.AddComponent<UIButtonTween>();
         serverListPanel.tweenTarget = PanleNext;
         serverListPanel.playDirection = AnimationOrTween.Direction.Forward;
         serverListPanel.ifDisabledOnPlay = AnimationOrTween.EnableCondition.EnableThenPlay;

         //隐藏自己panel
         UIButtonTween hidemePanel = go.AddComponent<UIButtonTween>();
         hidemePanel.tweenTarget = PanleMe;
         hidemePanel.playDirection = AnimationOrTween.Direction.Reverse;
         hidemePanel.disableWhenFinished = AnimationOrTween.DisableCondition.DisableAfterReverse;

         //添加点击事件，参数是服务器ID（点击获取本服务器ID的下所有角色）
         UIButtonMessage ubm = go.AddComponent<UIButtonMessage>();
         ubm.target = Playerlist;
         //给UIButtonMessage子增加传递‘参数’功能。
         ubm.functionName = "Playerlist";
         ubm.parameterStr = key;
     }

     /// <summary>
     /// 清空动态生成的按钮
     /// </summary>
     void cleantrendsButton()
     {
         GameObject[] tbs = GameObject.FindGameObjectsWithTag("trendsButton");
         for (int i = 0; i < tbs.Length; i++)
         {
             Destroy(tbs[i].gameObject);
         }
     }
