WaitForChild Hierarchy

function WaitForChildHierarchy(start,...)
        if not start:IsA("Instance") then return end
        local currentObj = start
        for _,v in pairs{...} do
                if type(v) == "string" then
                        currentObj = currentObj:WaitForChild(v)
                end
        end
        return currentObj

-- In case you have to do something stupid like for example:
local hat = workspace:WaitForChild("GameModel"):WaitForChild("Storage"):WaitForChid("Hats"):WaitForChild("Hat1")

-- You can just do this
local hat = WaitForChildHierarchy(workspace,"GameModel","Storage","Hats","Hat1")
