So when I walk away to the egg and press T, which is auto open, it says Attempt to index nil with EggParts."

Sorry for the laggy video

It can be difficult to look through a script with so many lines, like this one. So, if you can add comments to the line(s) that the error is occurring at, that may be helpful.

I see this line in your code twice. Is this the line that errors?

local CloneEgg = workspace.Eggs:FindFirstChild(Egg).EggParts:Clone()

Is Egg an Instance or a string? Because if Egg is an Instance, the script thinks you’re searching for an Instance in workspace.Eggs that’s named Egg’s ClassName, not Egg’s Name. And workspace.Eggs:FindFirstChild(Egg) will return nil if there’s nothing in workspace.Eggs named Egg’s ClassName – if Egg was a Model, the script would be searching for a child in workspace.Eggs named “Model”.

well the Egg is a string to get the egg model in the workspace.

4

OK. Is the line I provided the one that the error occurs at? And have you printed Egg to make sure that the string is a name of an “egg”?

5

Yeah it does print when you are near the egg and hatch but when I walk away too fast it causes the egg system to break.
