"Attempt to index function with CreatePath" bug

Help and Feedback Scripting Support

#1

I am making a pathfinding script for a game, but I have the NPC move to a certain point first

This is the section of the script

while true do
	for i, plr in pairs(game.Players:GetChildren()) do
		game.ReplicatedStorage.NewObjective:FireClient(plr, '<font color = "#ff0000">- GO TO CLASS!!!</font>')
	end

	local path = pathfind:CreatePath()
	path:ComputeAsync(hrp.Position, Vector3.new(-35.943, -210.411, 1595.615))
	local waypoints = path:GetWaypoints()

	for i,v in waypoints do
		if v.Action == Enum.PathWaypointAction.Jump then
			humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
		end
		humanoid:MoveTo(v.Position)
		script.Parent.Humanoid.MoveToFinished:Wait()
	end
	task.wait(10)
	local startTime = os.clock()
	repeat
		local found = everything()
	until found == nil or os.clock() - startTime > 30
	
	local path = pathfind:CreatePath()
	path:ComputeAsync(hrp.Position, Vector3.new(136.655, -209.552, 1451.934))
	local waypoints = path:GetWaypoints()
	
	for i,v in waypoints do
		if v.Action == Enum.PathWaypointAction.Jump then
			humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
		end
		player = task.spawn(fnp)
		if player then continue end
		humanoid:MoveTo(v.Position)
		script.Parent.Humanoid.MoveToFinished:Wait()
	end
	local distance = (hrp.Position - waypoints[#waypoints]).Magnitude
	if distance > 6 then continue end
	
	task.wait(math.random(60, 95))
	for i, plr in pairs(game.Players:GetChildren()) do
		game.ReplicatedStorage.NewObjective:FireClient(plr, '- Survive')
	end
end

The bugged line is the first

local path = pathfind:CreatePath()

This is the error that shows.

I haven’t been able to find any solutions on the DevForum and dont know what to do to fix it. I’ve tried changing the variable name and removing the variable altogether. I copied the code from a different portion of the script, so I don’t understand why it would bug here. There is a lot of pathfinding in the script so it could be that, but I just don’t get how it could be here. If anyone can help, thanks!

#2

shouldn’t it first be ComputeAsync and then CreatePath?

#3

No, like I said, the code works everywhere except for the spot I put it in.

#4

i’m going to ask a stupid question

but i assume pathfind is pathfinding service?

i cant’ see any errors besides the unknown-to-me pathfind variable

#5

Yep, very first line.

local pathfind = game:GetService("PathfindingService")

I will say, I did a little more experimenting and it might have to do with the while true do loop??? That caused every single pathfind to break exactly this way.

#6

i don’t see why that is, but i guess you can try not doing a while true loop

#7

You’re setting the variable pathfind to be equal to a function at some point, which is why the error is saying “attempt to index function with CreatePath”. Could you send the entire script?

#8

You’re right.

local function pathfind(player)
	for i, plr in pairs(game.Players:GetChildren()) do
		game.ReplicatedStorage.NewObjective:FireClient(plr, '<font color = "#ff0000">- GO TO CLASS!!!</font>')
	end

	local path = pathfind:CreatePath()
	path:ComputeAsync(hrp.Position, Vector3.new(-35.943, -210.411, 1595.615))
	local waypoints = path:GetWaypoints()

	for i,v in waypoints do
		if v.Action == Enum.PathWaypointAction.Jump then
			humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
		end
		humanoid:MoveTo(v.Position)
		script.Parent.Humanoid.MoveToFinished:Wait()
	end
	task.wait(10)
	local startTime = os.clock()
	
	local path = pathfind:CreatePath()
	path:ComputeAsync(hrp.Position, player.Character:FindFirstChild("HumanoidRootPart").Position)
	local waypoints = path:GetWaypoints()

	for i,v in waypoints do
		if v.Action == Enum.PathWaypointAction.Jump then
			humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
		end
		humanoid:MoveTo(v.Position)
		script.Parent.Humanoid.MoveToFinished:Wait()
	end
end

Haha. I do very similar stuff all the time and spend hours tracking down a very simple fix.
