So I’m making a roller coaster for my park and here and there it gets stuck on the camelback hill so i decided to add a respawn button in case. I tested it and it respawned good but the second time i tried to respawn it, it said, "cart is not a valid member of Model “Workspace.Roller Coasters.mEGALODON.carmain” and I need it to where when the new cart spawns in it goes in the “carmain” model. So, I tried that, and it says nothing’s wrong with the script so what’s happening???

local cartM = script.Parent.Parent.Parent
local delaytime = .2
script.Parent.cd.MouseClick:Connect(function()
	script.Parent.Parent.Parent.cart:Destroy()
	wait(delaytime)
	local newcart = game.ServerStorage.Regenvehicles["MEG cart"]:Clone()
	newcart.Parent = workspace["Roller Coasters"].mEGALODON.carmain


end)
	
	```

you could try checking if the cart isn’t nil

script.Parent.cd.MouseClick:Connect(function()
    if cart == nil then return end
	script.Parent.Parent.Parent.cart:Destroy()
	wait(delaytime)
	local newcart = game.ServerStorage.Regenvehicles["MEG cart"]:Clone()
	newcart.Parent = workspace["Roller Coasters"].mEGALODON.carmain


end)

when i try to respawn it it says cart is not a valid member of Model “Workspace.Roller Coasters.mEGALODON.carmain… And what does nil mean and how do i check it

4

nil just means nothing. You could check by doing this

  if cart == nil then return end

this will check if cart is nothing and if it is it would just not run the code under

all it did was say cart is not a valid member of Model “Workspace.Roller Coasters.mEGALODON.carmain

Ok then, you could try using FindFirstChild to look for it in workspace

if workspace:FindFirstChild(cart, true)then
workspace:FindFirstChild(cart, true):Destroy()
end

where do I add this in the script

8 
script.Parent.cd.MouseClick:Connect(function()
    if workspace:FindFirstChild(cart, true)then
workspace:FindFirstChild(cart, true):Destroy()
	wait(delaytime)
	local newcart = game.ServerStorage.Regenvehicles["MEG cart"]:Clone()
	newcart.Parent = workspace["Roller Coasters"].mEGALODON.carmain

end
end)
