function setup() {
  createCanvas(800, 600);
  video = createVideo('video.mp4');
  video.position(0, 0);
  video.size(width, height);

}

function mousePressed() {
  video.play();
}

function setup() {
  createCanvas(800, 600);
  video = createVideo('video.mp4', videoLoaded);
  // ...

function videoLoaded() {
  let button = createButton('点击按钮');
  button.position(10, 10);
  button.mousePressed(doSomething); // 点击按钮后执行doSomething函数
}

function doSomething() {
  // 在这里编写按钮点击后的逻辑
}
