使用 mousepressed 和 class

Question

我制作了这个音板，这是我的第一个项目，我很高兴能走到这一步:)

但是，我正在尝试将 mousePressed 与 class 一起使用，但它似乎无法正常工作，我希望它能够在单击一次时播放，在单击两次时停止。目前，当你将鼠标悬停在我的音板上的一个按钮上时，它会自动播放声音，直到你将它移到另一个按钮上。

谁能给我解释一下这个问题？

class sound{


  float x;
  float y;

  public sound(float x, float y) {
    this.x = x;
    this.y = y;
  } 
  void run()
  {
    draw();
    mousePressed();
  }

  void draw() {
    rect(x, y, 99, 99);
    fill(100, 10, 10);
  }
  void mousePressed(){
    if (mouseX > 1 && mouseX <  99  
    && mouseY > 1 && mouseY <  99) {
    s2.play();
    image(p7, 1, 1);
  } else {
    s2.pause();
    s2.rewind();
  }

  if (mouseX > 100 && mouseX < 199 
    && mouseY > 1 && mouseY < 99) {
    player.play();
    image(p9, 100, 1);
  } else {
    player.pause();
    player.rewind();
  }
  if (mouseX > 200 && mouseX <300
    && mouseY > 1 && mouseY < 99) {
    s7.play();
    image(p6, 200, 1);
  } else {
    s7.pause();
    s7.rewind();
  }

  if (mouseX > 1 && mouseX < 99
    && mouseY > 100 && mouseY < 199) {
    s8.play();
    image(p8, 1, 100);
  } else {
    s8.pause();
    s8.rewind();
  }

  if (mouseX > 100 && mouseX < 199
    && mouseY > 100 && mouseY < 199) {
    s3.play();
    image(p2, 100, 100);
  } else
  {
    s3.pause();
    s3.rewind();
  }

  if (mouseX > 200 && mouseX < 300
    && mouseY > 100 && mouseY < 199) {
    s6.play();
    image(p5, 200, 100);
  } else
  {
    s6.pause();
    s6.rewind();
  }

  if (mouseX > 1 && mouseX < 99
    && mouseY > 200 && mouseY < 299) {
    s1.play();
    image(p1, 1, 200);
  } else
  {
    s1.pause();
    s1.rewind();
  }
  if (mouseX > 100 && mouseX < 199 
    && mouseY > 200 & mouseY < 299) {
    s4.play();
    image(p3, 100, 200);
  } else
  {
    s4.pause();
    s4.rewind();
  }
  if (mouseX> 200 && mouseX < 299
    && mouseY > 200 && mouseY < 299) {
    s5.play();
    image(p4, 200, 200);
  } else
  {
    s5.pause();
    s5.rewind();
  }

  }

}

  size(300, 300);
  minim = new Minim(this);
  player = minim.loadFile("deadmau5.mp3");

  sound1.mousePressed();
    sound2.mousePressed();
  sound3.mousePressed();
  sound4.mousePressed();
  sound5.mousePressed();
  sound6.mousePressed();
  sound7.mousePressed();
  sound8.mousePressed();
  sound9.mousePressed();

}

void mousePressed() {
}

Answer 1

您正在从草图的 draw() 函数调用 Sound class 的 mousePressed() 函数。您实际上并没有检查用户是否按下了鼠标。

您可能只想将这些调用移动到草图的 mousePressed() 函数中。

Answer 2

void mousePressed(){
    if (mouseX > 1 && mouseX <  99  && mouseY > 1 && mouseY <  99) {
         s2.play();
         image(p7, 1, 1);
     }else {
         s2.pause();
         s2.rewind();
       }

我认为这里有问题，你检查你的鼠标位置在哪里，如果不在那个位置声音会暂停。
