在我们的Unity游戏项目中，GUI的表现采用NGUI。记录一下我们的处理方式：

需要解决的问题

1、需要处理大量按钮的点击事件

2、需要处理界面跳转事件

3、需要处理界面元素更新事件

解决方案

GUIClickEventReceiver

解决按钮点击事件

GUIManager

管理GUI的跳转与更新

具体实现

Inspector选择事件

在编辑器中为按钮选择点击事件

 

事件代码结构

主要逻辑

public void OnClick ()    {        bool playSoundEffect = true;        switch (clickType) {        case ClickType.StartGame:            GameManager.instance.startGame ();            break;        case ClickType.Store:            GUIManager.instance.showGUI (GUIState.Store);            break;        case ClickType.Stats:            GUIManager.instance.showGUI (GUIState.Stats);            break;        case ClickType.DoubleCoinUpgrade:            GameManager.instance.upgradePowerUp (PowerUpTypes.DoubleCoin);            break;        case ClickType.CoinMagnetUpgrade:            GameManager.instance.upgradePowerUp (PowerUpTypes.CoinMagnet);            break;        case ClickType.InvincibilityUpgrade:            GameManager.instance.upgradePowerUp (PowerUpTypes.Invincibility);            break;        case ClickType.AddSpeedUpgrade:            GameManager.instance.upgradePowerUp (PowerUpTypes.AddSpeed);            break;        case ClickType.ProtectionCoverUpgrade:            GameManager.instance.upgradePowerUp(PowerUpTypes.ProtectionCover);            break;        case ClickType.AttackGunUpgrade:            GameManager.instance.upgradePowerUp(PowerUpTypes.AttackGun);            break;        case ClickType.EndGame:            GUIManager.instance.showGUI (GUIState.EndGame);            break;        case ClickType.Restart:            GameManager.instance.restartGame (true);            break;        case ClickType.MainMenu:            GameManager.instance.backToMainMenu (false);            break;        case ClickType.MainMenuRestart:            GameManager.instance.backToMainMenu (true);            break;        case ClickType.Pause:            GameManager.instance.pauseGame (true);            playSoundEffect = false;            break;        case ClickType.Resume:            GameManager.instance.pauseGame (false);            break;        case ClickType.ToggleTutorial:            GameManager.instance.toggleTutorial ();            break;        case ClickType.Missions:            GUIManager.instance.showGUI (GUIState.Missions);            break;        }        if (playSoundEffect)            AudioManager.instance.playSoundEffect (SoundEffects.GUITapSoundEffect);    }
