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

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);

    }
