UnityXR Pico和HTCVive判断手柄连没连接上

标签:HTCVive UnityXR false 手柄 int button transform Pico ControllerDevice

       方法一:用InputDevices.GetDevices(),PICO中使用的此方法
            此方法获取当前连接的设备:
            1.在Pico中连上哪个手柄就有哪个手柄,正常使用。
            2.PC端HTCVive上不正常:
              InputDevices.GetDevices()方法会获取到所有连接过的设备,即使设备已断开:
              运行程序的时候两个手柄都连上,此方法获取的设备列表就会一直有这两个手柄,
              即使手柄断开,只有重启电脑或者STEAMVR,从方法获取到的就是当前连接的设备,
              总之,在重启电脑或者STEAMVR的情况下,程序运行时连接过的设备都会被获取到,
              即使再断开设备;

            方法二:判断手柄模型LeftBaseController和RightBaseController的本地位置是不是(0,0,0)
            1.在Pico中连上哪个手柄就有哪个手柄,正常使用。
            2.PC端HTCVive上不正常:
            当手柄连接时这两个物体的位置肯定不是(0,0,0),即使用户特意拿着手柄往(0,0,0)去对,也对不准确,
            但是这样也有问题。
              在HTCVive中左手柄会变为右手柄:
              两个手柄都连接时,断开右手柄,右手柄模型正常隐藏,左手柄正常使用,先断开左手柄,左手柄模型正常隐藏,右手柄也能正常使用,
              两个手柄都没连接时,先连接上右手柄再连接上左手柄,也能正常使用,对应的模型也对,
              两个手柄都没连接时,先连接上左手柄,左手柄就会先是左手柄(有左手柄模型),
              然后突然变为变为右手柄(同时在左手柄模型位置出现一个右手柄模型,左手柄模型就会一直在那个位置),
              此时如果不连接右手柄,刚才的连接的手柄就可以当右手柄正常使用,但是左手柄模型会一直在那,如果再连接上右手柄,
              右手柄就会是左手柄(右手柄会对应上左手柄的模型),此时就是左右手柄互换了,也能正常使用了;

            方法三:0.5秒获取一次模型位置,如果和上一次位置一样,就隐藏
              能正常使用
              本来想的是如果用方法三,那么手柄连接上,但是放在桌子上不去动,0.5秒后它就会被隐藏,但没办法,前两个方法都不行,只能用这个。
              但是实际上只有手柄没连接的时候模型不动,0.5秒后隐藏,手柄连接时放桌子上不动,0.5秒后并不会消失,不知道具体是什么原因,
              猜测是定位器不可能完全百分百准确定位,假如把手柄放到(1f,2f,3f)的位置不动,可能定位器定位手柄的位置的值每次都不一样,
              比如(1.001f,1.998,3.002f)等会有微小偏差。
