Roblox 中无错误但爆炸不起作用？

在 Roblox Studio 中，我想制作一个按钮，可以在某个塔上制造爆炸，为电视节目中的小游戏提供服务。所以我编写了这段代码，但由于某种原因，它没有起作用。如果我能得到一个确定的答案，我将不胜感激！

脚本：

local ClickDetector = script.Parent
ClickDetector.MaxActivationDistance = 10

ClickDetector.MouseClick:Connect(function()
    local Towers = workspace.Towers
    local BT = math.random(1,8)
    local BT2 = BT
    wait(0.2)
    if BT2 == "1" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Black.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "2" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.White.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "3" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Blue.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "4" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Brown.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "5" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Green.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "6" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Red.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "7" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Pink.boompart.Position
        boom.Parent = workspace

    elseif

        BT2 == "8" then
        local boom = Instance.new("Explosion")
        boom.Position = Towers.Yellow.boompart.Position
        boom.Parent = workspace

    end
    print(BT2)
end)
