[SOLVED] Why Does My AI Keep Getting Stuck

Help and Feedback Scripting Support
#1

I don’t know why, but for some reason my bot keeps on getting stuck in places, or waits a little bit sometimes when switching to a closer player. I am pretty new to pathfinding, so please explain to me the best you can. Here is my findPath() function:

function findPath(target)
	local path = game:GetService("PathfindingService"):CreatePath()
	path:ComputeAsync(myRoot.Position, target.Position)
	local waypoints = path:GetWaypoints()
	
	if path.Status == Enum.PathStatus.Success then
		for _, waypoint in ipairs(waypoints) do
			if waypoint.Action == Enum.PathWaypointAction.Jump then
				MyHuman.Jump = true
				findPath(target)
				break
			end
			MyHuman:MoveTo(waypoint.Position)
			local timeOut = MyHuman.MoveToFinished:Wait(1)
			if not timeOut then
				MyHuman.Jump = true
				print("Path was too long")
				findPath(target)
				break
			end
			if checkSight(target) then
				repeat
					local closestTarget = findClosestTarget()
					if closestTarget.Parent ~= target.Parent then 
						main()
						return 
					end
					MyHuman:MoveTo(target.Position)
					attack(target)
					wait(0.1)
					if target == nil then
						break
					elseif target.Parent == nil then
						break
					end		
				until checkSight(target) == false or MyHuman.Health < 1 or target.Parent.Humanoid.Health < 1
				break
			end
			if (myRoot.Position - waypoints[1].Position).Magnitude > 20 then
				findPath(target)
				break
			end
		end
	end
end

He also will sometimes stutter, when walking randomly if he finds no targets, here is the part for that:

function walkRandomly()
	local xRand = math.random(-50,50)
	local zRand = math.random(-50,50)
	local goal = myRoot.Position + Vector3.new(xRand, 0, zRand)
	
	local path = game:GetService("PathfindingService"):CreatePath()
	path:ComputeAsync(myRoot.Position, goal)
	local waypoints = path:GetWaypoints()
	
	if path.Status == Enum.PathStatus.Success then
		for _, waypoints in ipairs(waypoints) do
			if waypoints.Action == Enum.PathWaypointAction.Jump then
				MyHuman.Jump = true
			end
			MyHuman:MoveTo(waypoints.Position)
			local timeOut = MyHuman.MoveToFinished:Wait(1)
			if not timeOut then
				print("Stuck")
				MyHuman.Jump = true
				walkRandomly()
			end
		end
	else
		print("Path failed")
		wait(1)
		walkRandomly()
	end
end

Sorry if I am just throwing scripts at you, if you need me to further explain anything I can.

Edit: I forgot to mention that I am cloning the AI from ServerStorage into workspace during this process and when I test him starting in workspace, he works perfectly fine.

Thanks For Reading! :slightly_smiling_face:

Your code is doing recursive method-calls, without a proper/quick stop condition. - So your code most likely ends up with a ‘stack overflow ’ error.

Change your code, so it does it in an iterative way instead.

Here are some others with a similar problem, that also used a wrong ‘recursive’ method - with replies containing hints on how they could change their code into an ‘iterative’ setup:
