Problem with coroutine

[gunipotys (no_detonator)]

1. What do you want to achieve?
   I’m trying to make a npc to chase the player

2. What is the issue?
   I don’t know how to manage the while loop

3. What solutions have you tried so far?
   I tried lots of things but couldn’t fix my problem

The script I use :

local Rig = workspace.Hunter
local PathFinding = game:GetService("PathfindingService")
local RunService = game:GetService("RunService")
local Players = game.Players:GetPlayers()
local Start = Rig.HumanoidRootPart.Position
local End = workspace.End



local Range = 80
local Mode
local ActualTarget
local ActualTarget = 1

local ActualMode





--Rig.Humanoid.JumpPower = 100
local Path = PathFinding:CreatePath({
	AgentRadius = 3,
	AgentHeight = 6,
	AgentCanJump = true,
	--Costs = {
	--	--Plastic = math.huge,
	--	--Ice = 0
	--}
}
)



local function Trace(waypoint)
	local Part = Instance.new("Part", workspace)
	Part.Position = waypoint.Position + Vector3.new(0,1,0)
	Part.Size = Vector3.new(3,3,3)
	Part.Anchored = true
	Part.CanCollide = false
	Part.Color = Color3.new(0.447059, 1, 0.0235294)
end


local function SearchForTarget()
	--print("searching..")
	for i, plr in ipairs(game.Players:GetPlayers()) do
		plr = workspace:WaitForChild(plr.Name)
		if (plr:WaitForChild("HumanoidRootPart").Position - Rig.HumanoidRootPart.Position).Magnitude <= Range then
			--print("found !")
			return plr
		end
		--print("not found ! : ", (plr.HumanoidRootPart.Position - Rig.HumanoidRootPart.Position).Magnitude)
	end
end


local function CheckDistance(arg1)
	local Treshold = 10
	--print(arg1)
	local Magnitude = (Rig.HumanoidRootPart.Position - arg1.Position).Magnitude
	
	if Magnitude <= Treshold then
		return true
	end
end

local function CheckRange(target)
	if (target.Position - Rig.HumanoidRootPart.Position).Magnitude <= Range then
		return true
	else
		return false
	end
end

local reset = false

local function Recalculate (Target)

	Path:ComputeAsync(Rig.HumanoidRootPart.Position, Target.Position)

end

local function FindMode(target)
	
	--if not CheckRange() then return "no range" end
	
	if CheckDistance(target) then
		return "Move"
	else
		return "PathFinding"
	end
end

local function StopNavigation(actualTarget)
	local ActualMode = ActualMode
	local ShouldMode = FindMode(actualTarget)
	--print(ActualMode," = ", ShouldMode)
	
	if ActualMode ~= ShouldMode then
		return true
	else
		return false
	end
	
end
local STOP = false
local function stop()
	STOP = true
end






	



local function Target(target, mode)
	--print("choosen mode : ",mode)
	print("w")
	if mode == "PathFinding" then
		
		
		Recalculate(target)
		--print("path")

		local Waypoints = Path:GetWaypoints()

		if Path.Status ~= Enum.PathStatus.Success then return end



		--Verify if the closest target changed or it needs to stop pathfinding and move



		--PathFinding system
		for i, waypoint in pairs(Waypoints) do

			print("moving to : ",i)


			if waypoint.Action == Enum.PathWaypointAction.Jump then
				Rig.Humanoid.Jump = true
			end


			Rig.Humanoid:MoveTo(waypoint.Position)

			Rig.Humanoid.MoveToFinished:Wait()
		end
		
		
	elseif mode == "Move" then
		
		Rig.Humanoid:MoveTo(target.Position)
		
	end
	
end

local new

local IsRunning = false
while task.wait(0.1) do
	if IsRunning == true then
		coroutine.yield(new)
	end

	local PotentialTarget = SearchForTarget()

	if not PotentialTarget then continue end

	PotentialTarget = PotentialTarget:WaitForChild("HumanoidRootPart")

	ActualMode = FindMode(PotentialTarget)


	--Target(PotentialTarget,ActualMode)
	--Apply others to the target found : good

	--Check the mode : good

	--Give the mode to the target

	--Apply the mode
	--idk ?
	--
	--





	new = coroutine.create(function()
		Target(PotentialTarget, ActualMode)
	end)
	
	IsRunning = true
	
end

How should I procide for the final loop ?

Once you retrieve the path waypoints you just need a loop that calls humanoid:MoveTo() and switches waypoints as they are reached until stopped or no more waypoints are available.

As far as chasing a player goes. You’ll need to almost constantly update the path waypoints to the new destination of the player’s position.
