如果我說某個詞，激活一件事停用另一件事

我有一個激活影像并使其保持激活狀態的代碼，但如果滿足引數，我想更改為其他影像。如果我說某個詞，我想激活一件事并停用另一件事

uj5u.com熱心網友回復：

如果我對您的理解正確，您可能想要這樣的東西；shownImageSet如果沒有姿勢和標簽，則全域變數“保持”到最后一個值。

不需要flag/flag2變數。

// ... initialization code elided ...
let shownImageSet = 0;

function drawImages() {
  // Select image set based on pose   label
  if (pose) {
    if (label == "HowMuchCanYouSee") {
      shownImageSet = 1;
    }
    if (label == "Orochimaru") {
      shownImageSet = 2;
    }
  }

  if (shownImageSet) {
    // Need to show something?
    const eyeR = pose.rightEye;
    const eyeL = pose.leftEye;
    const d = dist(eyeR.x, eyeR.y, eyeL.x, eyeL.y);
    if (shownImageSet == 1) {
      image(img1, eyeL.x - d / 2, eyeL.y - d / 2, d, d);
      image(img1, eyeR.x - d / 2, eyeR.y - d / 2, d, d);
    } else if (shownImageSet == 2) {
      image(img4, eyeL.x - d / 1.53, eyeL.y - d / 1.5, (d * 3) / 2, (d * 3) / 2);
      image(img3, eyeR.x - d / 1.2, eyeR.y - d / 1.5, (d * 3) / 2, (d * 3) / 2);
    }
  }
}

function draw() {
  image(video, 0, 0);
  drawImages();
  fill(255, 0, 0);
  textSize(24);
  textAlign(CENTER, CENTER);
  text(label, 118, 15);
}
