如何与好友分享我的 javascript 游戏

Question

我正在练习用 HTML canvas 和 JavaScript 制作游戏。我正在制作一个飞扬的鸟克隆，它几乎完成了。我的一个朋友想看它，但我不知道他们怎么玩。我向他们发送了包含所有文件的文件夹，但看起来唯一的问题是当他尝试播放它时，他无法加载图像。我将如何让人们玩我制作的游戏。我是不是走对了，只是把文件夹发给他们了？

const canvas = document.getElementById("canvas");
const c = canvas.getContext("2d");
const backgroundImage = document.getElementById("image")
const flappyBirdImage = document.getElementById("flappy-bird-image");
const topPipe1Image = document.getElementById("top-pipe-image");
const bottomPipe1Image = document.getElementById("bottom-pipe-image");
const gainAPointSound = document.getElementById("gain-a-point-sound");
const startButtonImage = document.getElementById("start-button-image")
let pause = true;
let scoreSet = 0;
let controlsKeyDown = {up: false, right: false, down: false, left: false};
let dx = 2;
let dy = 2;
let score = 0;
let seconds = 0;
if(pause === false) {
let secondsInterval = setInterval(() => {
    seconds ++;
    console.log(seconds)
}, 1000)
}
canvas.width = innerWidth;
canvas.height = innerHeight;

Answer 1

嗯，最简单的解决办法就是把游戏放到网上:)。 Netlify 等服务可让您立即免费完成此操作。首先，您可以直接将文件拖放到 Netlify 中。 Netlify 为您创建了 public link* 形式的 somename.netlify.app，然后您可以与朋友分享。

上传文件时请确保没有绝对路径，因为这在其他机器上不起作用，更不用说互联网了。在您的源代码中，“D:/Coding/2d Games/Flappy Bird/Audio”是绝对路径的示例。您需要改用相对路径。至于你的图片，你需要确保你的项目文件夹有一个目录“/Flappy Bird Pictures and Animations”，并且它也被上传到 Netlify（或其他服务）。

*您还可以编辑 link 以防尚未使用。
