I am trying to fix this error but I can not figure how to debug it.
Workspace.Zombie.Script:7: attempt to index nil with 'Humanoid’

name="Humanoid"

robo=script.Parent:clone()

while true do
	wait(10)
	if script.Parent.Humanoid.Health<1 then
		robot=robo:clone()
		robot.Parent=script.Parent.Parent
		robot:makeJoints()
		script.Parent:remove()
	end
end

script.Parent seems to not exist at all, where is it parented to?

This code has some things you could improve on, aside from the bug;

Turn the while do loop into a function with a Died:Connect() event.
Replace the “remove()” with Destroy()
Clarify values a bit more, remove unneeded variables, make them local if required.

Now as far as the bug goes, it could be an issue with the script’s parent. Make sure it’s in a (with a humanoid) model and not a part inside the model.

The Model of the zombie. script = script, Parent = Model

In that case, change your if statement to this:

“if script.Parent:FindFirstChildOfClass(“Humanoid”) then”

If there’s still an error, there’s probably a parenting issue.

script.Parent.Humanoid.Died:Connect(function()
	local robo=script.Parent:clone()
	wait(10)
	if script.Parent.Humanoid.Health<1 then
		robo:clone()
		robo.Parent=script.Parent.Parent
		robo:makeJoints()
		script.Parent:Destroy()
	end
end)

That’s really odd. Even if there was a 10 seconds cycle, the script.Parent VANISHES into thin air. The mere possibility could even be that the zombie model flung or fell into the void.

You have 2 clones, one defined at line 2 and another defined at line 5.

I’d say keep the one at line 5 and turn it into a variable like you did with the one at line 2.

Also, even better, create a duplicate of your model, put it into ServerStorage, then when your model’s Humanoid dies, copy that model into the workspace.

I got the turn line 5 into a variable part. The only thing is how would i copy and paste the model from server storage into workspace?

Use Ctrl-D on the model you want to duplicate, put the duplicate (or the original, both work) into ServerStorage, then have a script that’ll fire when the one in workspace dies, optionally wait a bit, then spawn a new one by cloning the one that’s in ServerStorage

Code Sample:
function X()
game:GetService(“ServerStorage”):FindFirstChild(“ModelName”):Clone().Parent = workspace
end

do I need to have both or just 1 model?

You’ll probably need both, one in workspace to start things off, and one in ServerStorage for the respawn.

You removed the script’s Parent the first time the loop is run, so script.Parent = nil when the loop runs for a second time. Thus, it errors since Humanoid is not a member of nil.

What is the name of the object of the “Humanoid” class?

I don’t think this is related to the issue but you are detecting the script.Parent (zombie)'s Humanoid Health. Why not robo’s humanoid health? Also I don’t see any code deleting the script.Parent so this is odd.

The model could have fallen into the void or destroyed by some external script.

True, if the zombie have a script that respawns itself after 5 second, then it might be the issue, since the new script is using Humanoid.Died function

local zHumanoid=game.Workspace.Zombie:FindFirstChild("Humanoid")
zHumanoid.Died:Connect(function()
	game:GetService(“ServerStorage”):FindFirstChild(“Zombie”):Clone().Parent = workspace
end)

would that work? I put the script into ServerScriptService

Test it out. Tell us if there are any errors in the output.

The model does not have any external respawn script
