unity vr 数据手套接入

引言:最近搞一个vr项目,同时又需要接入数据手套.这个手套的牌子是诺依藤的.经过一段时间的折腾.终于将项目遇到的问题一一解决了.后面有其他小伙伴搞类似的工程的时候.可以对你有所帮助.

vr项目接入手套,将手柄的功能用手套取而代之,需要解决以下问题:1:手套代替手柄触发事件2:手柄触发的事件和UI交互3:手柄触发的事件和场景物体交互4:手柄触发事件是自身能在场景移动.

解决思路

1:手套代替手柄触发事件,我是通过手势来判断.将中指,拇指,掌心出建立一个小球.通过中指,拇指本别与掌心的碰撞来触发事件.

        1.1左手拇指与掌心触发自身位移移动事件.

        1.2右手拇指与掌心触发UI事件

        1.3 右手中指与掌心触发与场景交互事件

2:右手拇指与掌心贴合,发出射线,松开时触发UI事件

	private void OnTriggerStay(Collider col)
	{
		if (col.gameObject.layer != LayerMask.NameToLayer("Ignore Raycast"))
		{
            //拇指与中指贴合
			if(muzhi_controllui &&col.gameObject == muzhi_controllui.gameObject && interactionSys)
            {
				interactionSys.M_UIClick_onState();
			}
		}
	}
	private void OnTriggerExit(Collider col)
	{
		if (col.gameObject.layer != LayerMask.NameToLayer("Ignore Raycast"))
		{
            //拇指与掌心分开
			if (muzhi_controllui && col.gameObject == muzhi_controllui.gameObject && interactionSys)
			{
				interactionSys.M_UIClick_onStateUp();
			}
		}
	}

 射线和UI交互的部分当时我参考的是这位大神的文章https://blog.youkuaiyun.com/int_lin/article/details/111591340

3:右手中指与掌心贴合时,触发事件,此时检测手是否触发场景的物体.如果检测到中指与掌心分离时则触发相应的事件.

        trans = transform;
    }
    private void Update()
    {
        trans.localPosition = Vector3.zero;
    }
    //public bool IsZhuaWo { get; private set; }
    private void OnTriggerEnter(Collider col)
    {
        if (col.gameObject == xiao_zhi)
        {
            //开始抓握
            Debug.LogError("---------------------  抓握::");
        }

        if (rightController)

        {
            FollowMouse.instance.LeftPressDown();
        }
    }
    private void OnTriggerStay(Collider col)
    {
        //if (col.gameObject == xiao_zhi)
        //{
        //    IsZhuaWo = true;
        //    Debug.LogError("-------------------------  抓握::" + IsZhuaWo);
        //}
    }
    private void OnTriggerExit(Collider col)
    {
        //if (col.gameObject == xiao_zhi)
        //{
        //    IsZhuaWo = false;
        //    Debug.LogError("-------------------------  抓握::" + IsZhuaWo);
        //}
        if (rightController)
        {
            rightController.ZhuaWo(false);
        }
        if(leftController)
        {
            leftController.ZhuaWo(false);
        }
        if (FollowMouse.instance)
        {
            FollowMouse.instance.LeftPressUp();
        }
    }
}

4:左手拇指与掌心贴合时,向地面发出射线,松开时,射线与地面交互的点就是要瞬移的地方.
