Simple Path Enemy

Hello, this script isn’t working and the only error I get is

ServerStorage.SimplePath:25: SimplePath Error: Pathfinding target must be a valid Vector3 or BasePart


	--Import the module so you can start using it
	local ServerStorage = game:GetService("ServerStorage")
	local SimplePath = require(ServerStorage.SimplePath)

	--Define npc
	local Dummy = script.Parent

	-- Define a part called "Goal"
	local Goal = workspace.Part

	--Create a new Path using the Dummy
	local Path = SimplePath.new(Dummy)

	--Helps to visualize the path
	Path.Visualize = true



local npc = script.Parent
closestPlayer = nil
closestDistance = 200
function getClosestPlayer()
	
	for i, player in pairs(workspace:GetChildren()) do
		if player.Humanoid.Health ~= 0 and player.Name ~= Dummy then
			local distance = (npc.PrimaryPart.Position - player.PrimaryPart.Position).Magnitude
			if distance < closestDistance then
				closestPlayer = player
				closestDistance = distance
			end
		end
	end
end	

while true do

		Path:Run(closestPlayer)
	end

Doing closestPlayer.HumanoidRootPart.Position or anything like that doesn’t work as well please help thx

Consider verifying whether or not the player is nil.

Additionally, there is already a built-in function in simplepath that finds the player who is closest to the NPC. Try using it

#3

In this code below:

while true do
	Path:Run(closestPlayer)
end

It’s possible that closestPlayer is equal to nil, since it starts as nil. Instead of simply running it, add a condition.
Also, unless Path:Run() has a yield inside it, this will be an infinite unyielding loop, which will simply crash any server that it runs in. Consider adding a delay too:

while true do
	if closestPlayer then
		Path:Run(closestPlayer)
	end
	task.wait(0.75)
end

I no longer gives an error but the dummy doesn’t move?

You probably need to give the Path:Run() function an actual part, since right now I think it’s passing the character model. Also, instead of iterating over all of the workspace, try iterating over just players.

function getClosestPlayer()
	
	for i, player in pairs(game:GetService("Players"):GetPlayers()) do
		local Character = player.Character
		local PrimaryPart = Character and Character.PrimaryPart
		local hum = Character and Character:FindFirstChildOfClass("Humanoid")

		if PrimaryPart and hum and (hum.Health > 0) then
			local distance = (npc.PrimaryPart.Position - PrimaryPart.Position).Magnitude
			if distance < closestDistance then
				closestPlayer = Character
				closestDistance = distance
			end
		end
	end
end	

while true do
	if closestPlayer and closestPlayer.PrimaryPart then
		Path:Run(closestPlayer.PrimaryPart)
	end
	task.wait(0.75)
end

I was still having problems when I put in the code but turns out I just had a dumb mistake in the code, I forgot to actually call the function in the while loop but your code was correct anyways thx so much
