두 가지 컨트롤이있는 starling 게임을 개발 중입니다. 하나는 화면의 왼쪽에있는 아무 곳이나 손을 대고있는 왼쪽 사용자 들이며, 문자는 y 축을 위아래로 드래그합니다. 구현에 어려움을 겪고있는 다른 컨트롤은 화면의 오른쪽 하단에있는 하나의 버튼으로 캐릭터의 총알이 총알이됩니다.starling에서 터치 컨트롤을 어떻게 설정해야합니까?
제 질문은 버튼을 누를 때마다 문자가 화면 맨 아래로 뛰어 오르지 않고 어떻게 설정해야합니까?
이 기능을 사용하려면 멀티 터치를해야합니까?
더 구체적인 질문은 starling에 스프라이트에 대한 사각형을 정의하는 방법입니다. 찌르레기는 더 드로잉 API가 없기 때문에, 그냥
touchLayer.graphics.beginFill(0x000000, 0);
touchLayer.graphics.drawRect(0, 0, stage.stageWidth, stage.stageHeight);
touchLayer.graphics.endFill();
아무쪼록 잘 부탁드립니다. 감사합니다.
다음은 InGame 클래스의 전체 코드입니다.
