	Patrol()
end

The problem is i would like to stop the NPC When it reach a waypoint. The waypoints are in “local WayPoints = game.Workspace.Waypoints:GetChildren()” But i dont really know how i should do it. I tried to insert a “wait” under “Humanoid.MoveToFinished:Wait()” like that :

local function WalkTo(Destination)
	local Path = GetPath(Destination)

	if Path.Status == Enum.PathStatus.Success then
		
		
		for Index, WayPoint in pairs(Path:GetWaypoints()) do
			local Target = FindTarget()

			if Target and Humanoid.Health < 100 and not Target:FindFirstChild("NPC") then
				Capture(Target)
				Enemy.Humanoid.WalkSpeed = SprintSpeed
				break
			else
				if RunTrack.IsPlaying then
					RunTrack:Stop()
				end
				
				if not WalkTrack.IsPlaying then
					WalkTrack:Play()
				end
				
				Enemy.Humanoid.WalkSpeed = Walkspeed
				Humanoid:MoveTo(WayPoint.Position)
				Humanoid.MoveToFinished:Wait()
				
				
				wait(5)
			end
		end
	else
		Humanoid:MoveTo(Destination.Position - (Enemy.HumanoidRootPart.CFrame.LookVector * 10))
	end
	
end

but the NPC move very slow and dont reach the waypoints, i just wanna do when it reach a waypoint the NPC Have to wait like 5 seconds and move to another waypoint, but when i try to do that it appear like that :

Please help me with that issue i dont know how to fix that or make that.

MoveTo is broken, it “gives up” after 5 or 10 seconds or smht, can’t remember how long exactly. I don’t remember what happens to WaitForMoveToFinished when it gives up.

You could write your own MoveTo function to work around this, it wouldn’t be especially difficult. Ask away if you’d like some pointers for how to do it.

Looking at the video, it looks like it does exactly what you’re asking. It moves to a waypoint and waits a bit, then goes to the next one. Can you clarify what’s wrong in the video?
