[游戏开发]UnitySteamVR按键监听函数

如何配置一个自定义的按钮

点击+号创建 然后点击Save and generate保存 在点击 Open binding UI 打开编辑面板绑定按键

最后点击替换默认按键设置保存自己的修改

方法一

//--在update中监听按键---不推荐
private void Update()
    {
        //模范参数写按键的类型，函数参数写按键的名称，最后参数为按键的输入来源：左右手柄或任意手柄
        if (SteamVR_Input.GetAction<SteamVR_Action_Boolean>("Fire").GetState(SteamVR_Input_Sources.Any))
        {
            Debug.Log("Firing");
        }
        if (SteamVR_Input.GetAction<SteamVR_Action_Boolean>("Fire").GetStateUp(SteamVR_Input_Sources.Any))
        {
            Debug.Log("Fire Up");
        }
        if (SteamVR_Input.GetAction<SteamVR_Action_Boolean>("Fire").GetStateDown(SteamVR_Input_Sources.Any))
        {
            Debug.Log("Firing Down");
        }
    }

方法二

 void Start()
    {
        //---这种写法比较简单，但是无法指定输入手，并且需要在不用的时候一个个删除
        SteamVR_Actions.default_Fire.onStateUp += FireUp;
        SteamVR_Actions.default_Fire.onState += Firing;
        SteamVR_Actions.default_Fire.onStateDown += FireDown;
    }
 void End()
 {
	 	SteamVR_Actions.default_Fire.onStateUp -= FireUp;
        SteamVR_Actions.default_Fire.onState -= Firing;
        SteamVR_Actions.default_Fire.onStateDown -= FireDown;
 }
private void FireDown(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource)
{
    Debug.Log("Fire Down");
}
private void Firing(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource)
{
    Debug.Log("Firing");
}
private void FireUp(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource)
{
  	Debug.Log("Fire up");       
}

方法三

//--需要注意的是这种方式 按键持续状态下的监听事件要分别在按下和弹起监听函数中  添加/移除
 void Start()
 {
   	SteamVR_Actions.default_Fire.AddOnStateUpListener(FireUp,SteamVR_Input_Sources.Any);
    SteamVR_Actions.default_Fire.AddOnStateDownListener(FireDown,SteamVR_Input_Sources.Any);
 }
 void End()
 {
 	SteamVR_Actions.default_Fire.RemoveAllListeners(SteamVR_Input_Sources.Any);
 }

 private void FireDown(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource)
 {
     Debug.Log("Fire Down");
     SteamVR_Actions.default_Fire.AddOnUpdateListener(Firing, SteamVR_Input_Sources.Any);
 }
     private void Firing(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource, bool newState)
 {
     Debug.Log("Firing");
 }
 private void FireUp(SteamVR_Action_Boolean fromAction, SteamVR_Input_Sources fromSource)
 {
     Debug.Log("Fire up");
     SteamVR_Actions.default_Fire.RemoveOnUpdateListener(Firing, SteamVR_Input_Sources.Any);
 }
