mouseActionListener 및 mouseClick (MouseEvent e)

Question

명백한 이유 때문에 MouseListener를 내 게임에 구현했습니다. 사용자는 보드를 클릭 할 수 있어야합니다.

보드 자체를 클릭해도 문제가 발생하지 않습니다. 리셋 버튼 resetBoard을 사용하면이 문제가 생길 수 있습니다. 버튼을 클릭하면 보드가 변경되지만 클릭이 해제되면 보드가 다시 변경됩니다. 나는 내 행동이 모두 public void mouseClicked(MouseEvent e) 블록 아래에 있다는 것을 고려하여 다운 클릭과 릴리스 모두에서 왜 변경되는지를 설명하는 곳을 찾을 수 없습니다. 나는 비어있다 mouseReleased, mouseEntered, mouseExited, mousePressed.

기본적으로 mouseClicked이 비어 있지 않은 이유는 보드가 마우스 아래쪽과 위로 (동일한 동작에서) 모두 재설정된다는 것을 이해할 수 있습니까?

오, 나는 그 수입품 전부를 필요로하지 않는다는 것을 알고있다, 나는 그것들을 한순간에 사용했다. 나는이 현안에서 너무 소비 되었기 때문에 그들을 꺼내는 것을 잊었다.

반복해서 죄송합니다. 내가 현재하는 방법을 알고있는 유일한 방법.

감사합니다.

JButton에서 MouseListener를 사용하지 말고 대신 ActionListeners를 사용하십시오. 이 내용은 모두 button tutorial에 나와 있으며, 최대한 빨리 읽으시기 바랍니다. 난 당신의 코드를 참조

하나의 큰 문제는 여기에서 찾을 수있다 : 당신은 randomizer() 메소드가 호출 될 때마다 파일에서 모든 색상 블록 이미지를 다시 읽어

public ImageIcon randomizer() { 

    try { 
     purpleBlock.setImage(ImageIO.read(new File("purpleBlock.png"))); 
     redBlock.setImage(ImageIO.read(new File("redBlock.png"))); 
     blueBlock.setImage(ImageIO.read(new File("blueBlock.png"))); 
     greenBlock.setImage(ImageIO.read(new File("greenBlock.png"))); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    Random r = new Random(); 
    int rNum = r.nextInt(4); 

    if(rNum==0) { 
     return purpleBlock; 
    } else if(rNum==1) { 
     return redBlock; 
    } else if(rNum==2) { 
     return greenBlock; 
    } else { 
     return blueBlock; 
    } 
} 

. ImageIcon이 이미 적절한 이미지로 생성 되었기 때문에이 작업을 수행 할 필요는 없습니다.하지만이 작업만으로는 프로그램이 고통스럽게 다운 될 수 있습니다.

Answer 2

MouseListener 대신 단추에 ActionListener을 사용하십시오. 또한 숫자 접미사 만 다른 변수 이름을 사용하는 경우 배열을 대신 사용해야합니다. 코드 줄 수를 크게 줄일 수 있습니다. 49 대신 1 개의 선언 만 필요하며 버튼 변수에 액세스하는 대부분의 코드 섹션은 각각 1 줄로 줄여서 for 루프 (1 줄 + 닫는 중괄호)를 줄일 수 있습니다.
