NullReferenceException: Object reference not set to an instance of an object 에러 

OnButtonPressed, OnButtonReleased의 매개변수 VirtualButtonBehaviour가 VirualButtonAbstractBehaviour로 바뀌어야한다

변경전 코드

public void OnButtonPressed(VirtualButtonBehaviour vb) {
	}
	public void OnButtonReleased (VirtualButtonBehaviour vb){
	}


변경후 코드


public void OnButtonPressed(VirtualButtonAbstractBehaviour vb) {
	}
	public void OnButtonReleased (VirtualButtonAbstractBehaviour vb){
