UGUI交互E.gif

发射激光：

在StemVR中自带有SteamVR_LaserPointer的脚本，是用来控制激光。

SteamVR_LaserPointer.png

开启激光：

SteamVrLaserPointer.GetComponent().enabled = true;

在开启激光时，会创建一个cube，用来模拟激光

关闭激光:

SteamVrLaserPointer.GetComponent().enabled = false; //射线关闭

SteamVrLaserPointer.GetComponent().pointer.transform.localScale = new Vector3(0, 0, 0);

UI互交：

使用UnityEvent的目的是，绑定事件可视化

private PointerEventArgs pointerEventArgs;

public SteamVR_LaserPointer SteamVrLaserPointer;

public UnityEvent mOnEnter = null;

public UnityEvent mOnClick = null;

public UnityEvent mOnUp = null;

void OnEnable()

{

SteamVrLaserPointer.PointerClick += SteamVrLaserPointer_PointerClick;

SteamVrLaserPointer.PointerIn += SteamVrLaserPointer_PointerIn;

SteamVrLaserPointer.PointerOut += SteamVrLaserPointer_PointerOut;

}

void OnDestroy()

{

SteamVrLaserPointer.PointerClick -= SteamVrLaserPointer_PointerClick;

SteamVrLaserPointer.PointerIn -= SteamVrLaserPointer_PointerIn;

SteamVrLaserPointer.PointerOut -= SteamVrLaserPointer_PointerOut;

}

private void SteamVrLaserPointer_PointerOut(object sender, PointerEventArgs e)

{

if (e.target.gameObject == this.gameObject)

{

if (mOnUp != null) mOnUp.Invoke();

}

}

private void SteamVrLaserPointer_PointerIn(object sender, PointerEventArgs e)

{

if (e.target.gameObject == this.gameObject)

{

if (mOnEnter != null) mOnEnter.Invoke();

}

}

private void SteamVrLaserPointer_PointerClick(object sender, PointerEventArgs e)

{

if (e.target.gameObject == this.gameObject)

{

Debug.Log(e);

if (mOnClick != null)

{

mOnClick.Invoke();

}

}

}

当获取手柄的GrabGrip键，按下就执行互交
