如何创建一个"网状"物品掉落器?

有人可以帮我将这个脚本改成"网状"物品掉落器吗？

wait(2)
workspace:WaitForChild("PartStorage")

while true do
    wait(1.5) -- 每次掉落的间隔时间
    local part = Instance.new("Part",workspace.PartStorage)
    part.BrickColor=script.Parent.Parent.Parent.DropColor.Value
    part.Material=script.Parent.Parent.Parent.MaterialValue.Value
    local cash = Instance.new("IntValue",part)
    cash.Name = "Cash"
    cash.Value = 5 -- 掉落物品的价值
    part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.4,0)
    part.FormFactor = "Custom"
    part.Size=Vector3.new(1.2, 1.2, 1.2) -- 掉落物品的大小
    part.TopSurface = "Smooth"
    part.BottomSurface = "Smooth"
    game.Debris:AddItem(part,20) -- 掉落物品消失的时间
end
