On a physical controller, it is common for a portion of the physical control’s moment to be ignored near its neutral position. This part of the control is known as its deadzone. The
GCController element handles the deadzone and other physical constraints of the hardware control and computes a normalized value. The value is in a range from
1. If the value is
0, then the movement is in the deadzone. A non-zero value indicates the moment is outside of the deadzone. The value is normalized so that no values are lost because of the deadzone.
