Question

我最近在p5js网络编辑器上编写了一个代码，当我尝试复制代码并将其粘贴到应用程序中时，它显示错误

我试图整理代码仍然不起作用。

应用可能太旧了

我只会粘贴整个代码，因为idk错误所在

unction draw() {
  background(220);
  seconds = time / 100;
  time = time + popo;
  fill(112, 166, 255);
  text(start, po, pi);
  fill(178, 178, 178);
  rect(x, y, 20, 20);
  fill(255, 99, 99);
  triangle(x1, y1, x2, y2, x3, y3);
  console.log(seconds);
  x1 = x1 + trianglespeed;
  x2 = x2 + trianglespeed;
  x3 = x3 + trianglespeed;
  input.attribute('placeholder', "Enter speed");
  input.position(0, 410);
  if (!(input.value() >= 0)) {
    input.value("");
  }
  if (playing == true) {
    if (x1 <= 70) {
      trianglespeed = 0;
      fill(112, 166, 255);
      text("You lost.", 200, 200);
      x1 = x1;
      x2 = x1 + 10;
      x3 = x1 + 20;
      lost = true;
      fill(255, 76, 76);
      text("Press R to restart", 85, 330);
    }
  }
  if (aa == true) {
    fill(112, 166, 255);
    text("You Won.", 200, 200);
    fill(255, 76, 76);
    text("Press R to restart", 85, 330);
  }

  if (ab == true) {
    fill(112, 166, 255);
    text("You Clicked to early.", 120, 200);
    fill(255, 76, 76);
    text("Press R to restart", 85, 330);
  }

^^抽奖功能^^ vv设置功能vv

function setup() {
  createCanvas(400, 400);
  r = random(900, 4000);
  x = 100 - 20;
  y = 200 - 20;
  x1 = r
  y1 = 150;
  x2 = x1 + 10;
  y2 = 180;
  x3 = x2 + 10;
  y3 = 150;
  textSize(30);
  noStroke();
  start = "Click screen to play";
  trianglespeed = 0;
  lost = false;
  playing = false;
  win = false;
  po = 60;
  pi = 100;
  input = createInput();
  aa = false;
  ab = false;
  pressed = false;
  time = 0;
  popo = 0;
}

当我启动它/单击运行它显示错误

: Uncaught SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
"%cDid you just try to use p5.js's str() function? If so, you may want to move it into your sketch's setup() function.\n\nFor more details, see: github.com/processing/p5.js/wiki/Frequently-Asked-Questions#why-cant-i-assign-variables-using-p5-functions-and-variables-before-setup"

Answer 1

我认为您需要在代码的第一行中的“联合”之前添加“ f”。

由于setup函数中的所有变量都是局部变量，因此它们不会在draw函数中注册，从而导致错误。

要解决该错误，请将“ let”放在变量前面，然后在任何函数之外声明变量。

我无法在p5js应用中打开代码，我在p5js网络编辑器中创建了代码
