자바에서 타일 찾기 (타일 된지도)

Question

여기지도 주위를 움직이는 그림이있는 코드가 있습니다.

지도 타일과 상호 작용할 때이 그림을 숨기는 방법은 무엇입니까? 나는 아무 아이디어도 없다 그래서 나는 자바에 초심자이다. 어떤 도움이나 조언도 환영합니다.

도움을 주셔서 감사합니다!

Answer 1

좋은 접근 방식은 시각적 모델과 현실 모델을 분리하는 것입니다. 그것은 프로그램의 깊숙한 곳을 의미합니다. 당신은 당신의 "물리학 법칙"과 모든 물체를 가지고 있으며, 그 모델에 기초하여 그것을 그립니다.

당신은 그럼이 세상을 실행하는 "게임 컨트롤러"의 일종을 가지고 좋은이

public class ObjectInMyGame{ 
    private int posx; 
    private int posy; 
    private int width; 
    private int height; 
    private Image image; 
    private int movingX; 
    private int movingY; 
    //Note that it is good to use Point or something like that, instead of posx, posy. 
} 

같은 클래스를 만드는 시작할 수 있습니다. 그는 충돌 여부를 다음 무엇을 결정하는 경우

public class GameController{ 
    List<ObjectInMyGame> objects; 

    public updateGame(){ 
    for (ObjectInMyGame object : objects){ 
     object.doSomething(); //sometimes it is good idea to let objects itself do something 
    } 
    } 
} 

그래서 예를 들어, 당신은 객체를 이동할 때, 당신은 확인할 수 있습니다.
