ive tried looking on the dev forum however nothing rlly helped so…

heres the script i currently have in both the module script and the script script

local policemodule = {}

function wander(hum, root)
	
	local area = Vector3.new(root.Position.X + math.random(-30, 30), 0, root.Position.Z + math.random(-30, 30))
	local pathfinding = game:GetService("PathfindingService")
	local path = pathfinding:CreatePath({
		AgentCanJump = true,
		AgentCanClimb = true
	})

	path:ComputeAsync(root.Position, area)

	for i, waypoint in pairs(path:GetWaypoints()) do
		local waypoints = path:GetWaypoints()

		if waypoint.Action == Enum.PathWaypointAction.Jump then
			hum.Jump = true
		end

		hum:MoveTo(waypoint.Position)
		local timeout = hum.MoveToFinished:Wait(1)
		local nearest = findnearest()

		if raycastsight(nearest) then
			policemodule.walktotarget(nearest)
			break
		end

		if not timeout then
			hum.Jump = true
			wander(area)
			break
		end
	end
end

function findnearest(root)

	local maxdist = 300
	local nearest = nil

	for i, v in pairs(workspace:GetChildren()) do
		local vhum = v:FindFirstChild("Humanoid")
		local vroot = v:FindFirstChild("HumanoidRootPart")
		local status = v:FindFirstChild("Type")
		
		
		if vhum and vroot and status.Value ~= "Cop" and vhum.Health > 0 then
			if nearest == nil then
				nearest = vroot
			end
			
			if (root.Position - vroot.Position).magnitude <= maxdist then
				maxdist = (root.Position - vroot.Position).magnitude
				nearest = vroot
			end
		end
	end
	return nearest
end

function policemodule.walktotarget(root, hum, character)

	local nearesttarget = findnearest(root)

end

function raycastsight(nearest, character)

	if nearest then

end

function shoot(root, placetoshoot)

	if placetoshoot then

end

function bullet(startingpos, direction)

	local bullet = game.ReplicatedStorage.Bullet:Clone()
	bullet.CFrame = CFrame.new(startingpos, direction)
	bullet.Parent = workspace

	game:GetService("Debris"):AddItem(bullet, 5)
end

return policemodule


local module = game.ReplicatedStorage.ModuleScript
local req = require(module)

while true do
	task.wait(1)
	req.walktotarget()
end

sorry if this is topic is kinda unclear, also my coding is horrible and im trying to get better. pls criticize me, but also help me find out the coding error :+1: :+1:

You have it set up so walktotarget expects 3 inputs, but are providing it with 0.
Please adjust where you call the function so that the expected parameters are provided
