EasyTouch Rotating lens from the official example of Easytouch, its left rocker is not the control of the overall rotation of the lens, and left joystick control up and down rotation, right joystick control around rotation, very inconvenient. If you only use a rocker to achieve the left and right rotation of the lens, its own coordinate system will be crooked, that is, the lens will appear crooked situationAfter many tests, I found that as long asin theCameraCreate a parent object in the upper l
