我知道我做错了什么,但我找不到到底是什么(漫长的一天编码)。

我需要实现粒子模拟器。我有一些课程,我需要在右键单击时创建几个发射器。

一些代码:

public final class Viewport extends JComponent implements ActionListener {

  private AffineTransform transform = new AffineTransform();
  private ArrayList particleList = new ArrayList();
  ParticleEmitter emitter1;
  private Timer timer;
  double x;
  double y;

  public Viewport() {
    particalEmitterImport();
  }


  public void particalEmitterImport() {

    initComponents();
    timer = new Timer(30, this);
    emitter1 = new ParticleEmitter(3);
    timer.start();
    timer.setInitialDelay(0);
    //repaint();
    x = 0;
    y = 0;
    transform.setToIdentity();
  }

  public void particalEmitterImport(int mouseX, int mouseY) {

    initComponents();
    timer = new Timer(30, this);
    emitter1 = new ParticleEmitter(3);
    timer.start();
    timer.setInitialDelay(0);

    x = mouseX;
    y = mouseY;
    transform.setToIdentity();
  }

主类:

private void viewportMouseClicked(java.awt.event.MouseEvent evt) {                                      
    Viewport vw = new Viewport();
    if (SwingUtilities.isRightMouseButton(evt)) {
        xMouse = evt.getX();
        yMouse = evt.getY();
        vw.particalEmitterImport(xMouse, xMouse);
        vw.setLocation(xMouse,yMouse);
        System.out.println("CLICK");
        System.out.println(xMouse);
        System.out.println(yMouse);
        vw.setVisible(true);
    }

问题是我看不到我的发射器,但在输出中我看到了我从事件中获得的所有值。

w.particalEmitterImport(xMouse, xMouse);
                                ^^^^^^

我想你说:

w.particalEmitterImport(xMouse, yMouse);
                                ^^^^^^
