javascript - 有没有办法可以在两个 : this.Bullets.push(this.ship.shoot()); 之间设置延迟

Question

有没有办法在两者之间添加延迟；this.bullets.push(this.ship.shoot());

if (this.mscore >= 1000) {
  if (input.isPressed("spacebar")) {

    this.bullets.push(this.ship.shoot());
    this.bullets.push(this.ship.shoot());

  }
}

Answer 1

一种可能的解决方案是使用 setTimeout()，在下一个示例中，第二个代码将在大约 1000ms 后执行:

let delay = 1000;

if (this.mscore >= 1000)
{
    if (input.isPressed("spacebar"))
    {
        this.bullets.push(this.ship.shoot());
        let that = this;

        setTimeout(
            () => that.bullets.push(that.ship.shoot()),
            delay
        );
    }
}
