🥐 키보드 입력 이벤트 리스너

- 키패드 버튼을 눌렀을 때 키보드 이벤트 리스너가 작동하여 해당 키보드 이벤트 처리

- 키보드 눌렀을 때 애니매이션 처리 및 음악 재생

- 완전한 키보드 이벤트 처리 방법

분명 코드를 잘 작성했는데 키보드가 인식이 안됐다...그래서 뭐가 문제인지 봤더니...

이미지를 제대로 인식하지 못했다...

 

이럴 때 이미지를 제대로 인식했나 못했나 확인을 해야한다.

확인 하는 방법은.......

 

🍔 해결 방법

public void pressS() {
		// 매우 중요 
        System.out.println(Main.class.getResource("../images/noteRoutePressed.png"));
		noteRouteSImage = new ImageIcon(Main.class.getResource("../images/noteRoutePressed.png")).getImage();

		new Music("drumSmall1.mp3", false).start();
	}

System.out.println(Main.class.getResource("../images/noteRoutePressed.png"));
으로 파일을 잘 인식했는지 확인한다....

 

분명 폴더 안에 파일이 있는데도 파일을 인식하지 못해서...몇시간 동안 헤맸다...

 

이 글을 읽는 사람에게는 그런 시간이 낭비 되지 않기를 바라며...
