AI Chase System failing to avoid getting stuck

Help and Feedback Scripting Support

Hello, I’ve been trying to learn how to use the PathfindingService for testing in my game, but I keep failing to do so. The AI messes up entirely on it’s path.

I’ve tried looking around the DevForum and other sites to find a solution but none of them were answering my question on how to get the nearest character targeted.

Here’s an image, of how it acts.

The AI manages to only Follow you, but I know why it’s most likely breaking is because I’m not waiting for it to stop after reaching the destination. But the problem is, it’ll just go after the last position I was in then try to go after the players.

I want it to achieve by using AI Pathfinding to get any near players and target those who are near, and will not get stuck or go after the remaining position.

Here is my coding so far.

local RunService = game:GetService("RunService")
local Pathfinding = game:GetService('PathfindingService')

local TweenService = game:GetService("TweenService")

local Path = Pathfinding:CreatePath()

local Friendly = false
local Damage = 1

local Debounce = false

local Character = script.Parent
local Humanoid = Character:WaitForChild("Humanoid")

function GetNearestCharacters()
	local ClosestCharacter, Distances = nil,100
	
	for _, Player in pairs(game.Workspace:GetChildren()) do
		if Player:FindFirstChild("Humanoid") and Player ~= Character then
			local Distance = (Character.PrimaryPart.Position - Player.PrimaryPart.Position).Magnitude
			
			if Distance < Distances then
				ClosestCharacter = Player
				Distances = Distance
			end
		end
	end
	return ClosestCharacter, Distances
end

while wait() do
	local Player, Distance = GetNearestCharacters()
	if Player then
		Path:ComputeAsync(Character.PrimaryPart.Position, Player.PrimaryPart.Position)
		
		if Path.Status == Enum.PathStatus.Success then
			local Waypoints = Path:GetWaypoints()

			for _,Waypoint in pairs(Waypoints) do
				
				if Waypoint.Action == Enum.PathWaypointAction.Jump then
					Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
				end
				
				Humanoid:MoveTo(Waypoint.Position)
			end
		elseif Path.Status == Enum.PathStatus.NoPath then
			warn("PathStatus was a failure, retrying...")
		end
	end
end

I’d like atleast an understanding or a correction in my programming, I’m new to pathfindingservice so this might be the most annoying to work with lol.

Under Humanoid:MoveTo(Waypoint.Position) add Humanoid.MoveToFinsihed:Wait()
You could make this better by checking if the monster can actually see the player’s character. If it can see the character then u don’t have to wait for every waypoint but can instead straight up move to the character. If it can’t see the character then make it walk to the waypoints and do Humanoid.MoveToFinished:Wait()

Hope this helps!

The reason to why this is the case is because it straight up walks to the last waypoint and doesn’t wait for the waypoints before it

Yeah. It is literally walking to points A & D and missing B & C. Going straight to the point. Well explained. (A, B, C, D).
