NGUI中如何获取当前点击的物体

NGUI的UICamera中定义了一个内部类MouseOrTouch表示当前的输入设备：鼠标，Touch，或是游戏杆。

//begin源代码//

public class MouseOrTouch

{

public Vector2 pos; // Current position of the mouse or touch event

public Vector2 delta; // Delta since last update

public Vector2 totalDelta; // Delta since the event started being tracked

public Camera pressedCam; // Camera that the OnPress(true) was fired with

public GameObject current; // The current game object under the touch or mouse

public GameObject pressed; // The last game object to receive OnPress

public float clickTime = 0f; // The last time a click event was sent out

public ClickNotification clickNotification = ClickNotification.Always;

public bool touchBegan = true;

public bool pressStarted = false;

public bool dragStarted = false;

}

//end源代码//

在MouseOrTouch中定义了当前点击的物体：current

当我们点击某个物体时，只需要调用UICamera.currentTouch.current即可获取具体点击的是哪个物体。

这个方法是为了在不同的按钮使用同一点击事件时非常有效。

例如：在滚动列表子项中的所有按钮的响应事件都为OnUpgradeBtnClick。在OnUpgradeBtnClick中调用 UICamera.currentTouch.current即可获取我点击的具体按钮。从而知道他的数据：UIData uiData = curObject.transform.parent.GetComponent<UIData>();

for (int i = 0; i < list.Count; i++) {

SerEquip equip = list [i];

GameObject upgradeItem = NGUITools.AddChild (upGradeTable.gameObject, PrefabMgr.Instance ().GetPrefab ("GUI/Main/Equipment/Item/UpgradeItem"));

UIData uiData = upgradeItem.AddComponent<UIData> ();

uiData.Data = equip;

//UpgradePanel下的upgrade按钮的响应函数//

GameTools.EventClick (upgradeItem, "upGradeBtn", wndObject, "OnUpgradeBtnClick");

}

//升级面板 下upgrade按钮响应函数//

public void OnUpgradeBtnClick()

{

GameObject curObject = UICamera.currentTouch.current;

UIData uiData = curObject.transform.parent.GetComponent<UIData>();

WndMgr.Instance().ToggleWnd((int)UIType.Equip);

UpgradeWnd upgradeWnd = (UpgradeWnd)WndMgr.Instance().ShowWnd((int)UIType.Upgrade);

upgradeWnd.SetEquip((SerEquip)uiData.Data);

}
