Pathfinding monster to player

Help and Feedback Scripting Support

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to make a monster path-find it’s way to a player.

  2. What is the issue? Include screenshots / videos if possible!
    The monster path-finds to the players location but if the player moves the monster continues to walk to the players old location.

(I followed this video but once the monster finds a target it doesn’t pathfind which I want it to do

Line 60 to 63 is where the problems at

local monster = script.Parent
local humanoid = monster.Humanoid
local PathfindingService = game:GetService("PathfindingService")
local rs = game:GetService("ReplicatedStorage")
local jumpscareEvent = rs:WaitForChild("Remotes"):WaitForChild("Jumpscares"):WaitForChild("Jumpscare1")
local cameraToPlayerEvent = rs:WaitForChild("Remotes"):WaitForChild("cameraToPlayerEvent")
local playHeartbeat = rs:WaitForChild("Remotes"):WaitForChild("playHeartbeat")
local stopHeartbeat = rs:WaitForChild("Remotes"):WaitForChild("stopHeartbeat")
local heartbeatTarget
monster.PrimaryPart:SetNetworkOwner(nil)

local function findTarget()
	local players = game.Players:GetPlayers()
	local maxDistance = 80
	local nearestTarget
	
	for i, player in pairs(players) do
		if player.Character then
			local target = player.Character
			local distance = (monster.HumanoidRootPart.Position - target.HumanoidRootPart.Position).magnitude
			
			if distance < maxDistance then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end
	
	return nearestTarget
end

local function getPath(destination)
	local pathParams = {
		["AgentHeight"] = 15,
		["AgentRadius"] = 6.5,
		["AgentCanJump"] = false
	}
	local path = PathfindingService:CreatePath(pathParams)

	path:ComputeAsync(monster.HumanoidRootPart.Position, destination.Position)
	return path
end

local function attack(target)
	local distance = (monster.HumanoidRootPart.Position - target.HumanoidRootPart.Position).magnitude
	local plr = game.Players:GetPlayerFromCharacter(target)
	local path = getPath(target.HumanoidRootPart)

	if distance > 8 then
		if heartbeatTarget == nil then
			playHeartbeat:FireClient(plr)
			heartbeatTarget = plr.Name
		elseif heartbeatTarget == plr.Name then
		elseif heartbeatTarget ~= plr.Name and heartbeatTarget ~= nil then
			stopHeartbeat:FireAllClients()
			playHeartbeat:FireClient(plr)
			heartbeatTarget = plr.Name	
		end
		
--THIS IS WHERE THE ISSUE IS
		for i, waypoint in pairs(path:GetWaypoints()) do
			humanoid:MoveTo(waypoint.Position)
			humanoid.MoveToFinished:Wait()
		end
	else
		local AttackAnim = humanoid:LoadAnimation(script.Attack)
		AttackAnim:Play()
		target.Humanoid.Health = 0

		jumpscareEvent:FireClient(plr)
		wait(0.5)
	end
end

local function walkTo(destination)
	local path = getPath(destination)
	
	for index, waypoint in pairs(path:GetWaypoints()) do
		local target = findTarget()
		if target and target.Humanoid.Health > 0 then
			print("New Target: ", target.Name)
			attack(target)
			humanoid.WalkSpeed = humanoid.AttackingSpeed.Value
			break
		else
			humanoid.WalkSpeed = humanoid.PatrolSpeed.Value
			humanoid:MoveTo(waypoint.Position)
			stopHeartbeat:FireAllClients()
			heartbeatTarget = nil
			humanoid.MoveToFinished:Wait()
		end
	end
end

local function patrol()
	local waypoints = workspace:WaitForChild("Waypoints"):GetChildren()
	local randomNum = math.random (1, #waypoints)
	walkTo(waypoints[randomNum])
end


while wait(.001) do
	patrol()
end

its bec the monster is creating only one path


local path = PathfindingService:CreatePath(pathParams)

idk what do i do here but maybe try put this line in a while loop?

I haven’t read the whole script but you can do the following:

game:GetService("RunService").Heartbeat:Connect(function()
    if (target.Humanoid.MoveDirection).Magnitude > 0 then -- checks if player is moving
        local target = findTarget()
        attack(target)
    end
end)

Just keep checking if the player is moving and if the player is moving then you can make the monster attack the player.
