魔改Minecraft Classic网页重制版的地形生成器 II

最近又想起了Mojang的2020愚人节更新20w14infinite，就翻了翻反混淆后的彩蛋维度代码，发现原理很简单，效果却很有趣，所以又把之前玩过的Minecraft Classic重制版又拿出来，用JavaScript实现一下我比较喜欢的几个维度的生成。为了方便各位读者自行尝试，我将修改后的版本放在了Gitee Pages上托管(https://devbobcorn.gitee.io/minecraft-classic)，修改版本添加了一个启动器，便于玩家修改材质和世界生成代码。

下面是我写的两个例子，在启动器设置里把自定义世界生成代码（Custom World Generator Code）选成自定义（Custom）,然后在代码框中插入下列片段即可在线体验（仅限电脑）。

// This is an example of custom world generation.
// Note that the names of variables differ from those in preset code.
function checkPos(x,y,z){
	return (x >= 0 && x < xSize && y > 0 && y < ySize && z >= 0 && z < zSize);
}

for (var i = 1;i <= 20;i++){
	var ballx = Math.ceil(Math.random() * 200);
	var ballz = Math.ceil(Math.random() * 200);
	var bally = Math.ceil(Math.random() * 15) + 32;
	var radius = 3 + Math.ceil(Math.random() * 12);
	for (var x1 = ballx - radius - 1;x1 <= ballx + radius + 1;x1++)
		for (var z1 = ballz - radius - 1;z1 <= ballz + radius + 1;z1++)
			for (var y1 = bally - radius - 1;y1 <= bally + radius + 1;y1++)
				if (checkPos(x1,y1,z1) && ((x1-ballx)**2+(z1-ballz)**2+(y1-bally)**2 <= radius**2)){
					tiles[parseInt((y1 * zSize + z1) * xSize + x1)] = (y1 + z1 + x1) % 13 + 24;
				}
}
tiles; // This will serve as the return value of eval function.
