标牌

Coddy Roblox 游戏：工厂大亨课程的第 7 课，共 22 课。

工厂上方的标牌会显示工厂属于谁。零件表面上的文字是零件内的 SurfaceGui，其中包含一个 TextLabel。给标签命名后，就能轻松再次找到它。用一个小函数统一管理标牌的所有更改：

local gui = Instance.new("SurfaceGui")
gui.Parent = tycoon.Sign

local signLabel = Instance.new("TextLabel")
signLabel.Name = "Status"
signLabel.Size = UDim2.fromScale(1, 1)
signLabel.TextScaled = true
signLabel.Text = "Opening soon"
signLabel.Parent = gui

UDim2.fromScale(1, 1) 会让标签填满整个表面，而 TextScaled 会让文字适应标签。

挑战

中等

在工厂上方放一个牌子，显示工厂属于谁。

在 tycoon.Sign 中添加一个 SurfaceGui，其中包含一个名为 Status 的 TextLabel，让它填满 SurfaceGui，并显示缩放后的文字 Step on the green pad to claim this factory。
编写 setSign(text)，让它设置该标签的 Text。
工厂被认领时，调用 setSign(player.Name .. "'s Factory")。

按“开始”，然后踩上绿色垫子：牌子会显示你的名字。接着按“检查”。
