流星雨

Coddy Roblox 游戏：灾难生存课程的第 12 课，共 20 课。

第二场灾难会在整轮游戏期间每隔半秒落下一颗燃烧的流星。等待的循环会拖慢本轮的倒计时，所以它会通过 task.spawn 同时运行：

task.spawn(function()
	while map.Parent do
		-- 落下一颗陨石
		task.wait(0.5)
	end
end)

while map.Parent do 会自动停止：本轮游戏销毁地图时，地图的 Parent 会变成 nil。每颗流星都会落在随机位置，距离岛屿中心 math.random(-15, 15) 个 studs；Debris:AddItem(meteor, 4) 会在 4 秒后将其移除，避免流星堆积。

目前，这一轮会用流星代替洪水。第 13 课会让它做出选择。

挑战

中等

添加一场流星雨。

在顶部获取 Debris 服务。
编写 Disasters.Meteors(map)：在 task.spawn 中循环执行 while map.Parent do，每次循环都调用 task.wait(0.5)。
每次循环都在地图中创建一个未锚定的 3 × 3 × 3 球体，命名为 Meteor，位置在 map.Base 上方 40 studs、半径 15 studs 范围内；触碰时会击败玩家；调用 Debris:AddItem(meteor, 4)。
调用它来代替 Disasters.Flood(map)。

按“开始”：流星会在整轮游戏中落向岛屿。然后按“检查”。
