2d向量数学（速度和加速度）箭头汽车运动

Question

我似乎无法使用箭头功能。
我的问题是，当我使用箭头函数时，我无法计算矢量数学。
你能帮我解决共享代码的#move函数中的矢量数学问题吗？
我已经正确地实现了箭头功能，我需要帮助的代码在#move 中。

class Vehicle {
  constructor(x, y, width, height, color) {
    this.x = x;
    this.y = y;
    this.width = width;
    this.height = height;
    (this.location = new Vector2d(this.x, this.y)),
    (this.acceleration = new Vector2d(0.2, 0.2)),
    (this.velocity = new Vector2d(0, 1)),
    (this.maxSpeed = 5);
    this.minSpeed = 1;
    this.angle = 0;
    this.color = color;
    this.controls = new Controls();
  }
  update() {
    this.#move;
  }

  #move() {
    if (this.controls.forward) {
      this.velocity.set(0, 1);
      this.velocity.add(this.acceleration);
      this.velocity.limit(this.maxSpeed);
      this.location.add(this.velocity);
    }
    if (this.controls.reverse) {
      this.velocity.set(0, -1);
      this.velocity.sub(this.acceleration);
      this.velocity.limit(this.minSpeed);
      this.location.add(this.velocity);
    }

    while (this.velocity > 0) {
      if (this.controls.left) this.angle += 0.03;
      if (this.controls.right) this.angle -= 0.03;
    }
    this.x -= Math.sin(this.angle) * this.velocity.x;
    this.y -= Math.cos(this.angle) * this.velocity.y;
  }

  draw(ctx) {
    ctx.save();
    ctx.translate(this.x, this.y);
    ctx.rotate(-this.angle);

    ctx.beginPath();
    ctx.fillStyle = this.color;
    ctx.rect(-this.width / 2, -this.height / 2, this.width, this.height);
    ctx.fill();
    ctx.restore();
  }
}
