Question

我正在做一个打鼹鼠的游戏，这是我到目前为止所做的，我知道这很草率，可能不是最简单/最聪明的方法。我需要知道的是如何让我的动画在不同的时间动画。这个当前的代码用于动画9个不同的鼹鼠来自洞，但我需要它们在不同的时间动画（所以它们不会同时出现，或者在彼此的几毫秒内出现）我当前的代码是

Answer 1

在0和您的开始时间变化之间生成9个随机数。确定动画之间所需的最大距离，并将随机数缩放到该时间范围。然后，将9个计时器设置为从现在开始的那些时间，以便每个计时器启动动画。

如果您希望动画启动超过500毫秒，您可以执行以下操作：

var randomTimes = [9];

for (var i = 0; i < 9; i++) {
    randomTimes[i] = Math.floor(Math.random() * 501);
}

现在你有超过500毫秒的9个随机时间，你可以使用这些值和setTimeout随机启动每个动画。

Answer 2

以这种方式复制/粘贴功能确实很草率！

您需要设置一个标志：

var isMole  = false;//at first there is no mole
if(!isMole){    
   //there is no mole, you can show one here    
   isMole = true;//there is a mole now!
}else{
   //there is a mole, we wait.
}

现在，当鼹鼠超时或用锤子敲击时，将该标志设为假！

我如何在不同时间制作这些动画？
