Help with ai stopping (PLEASE READ)

adawe678 · January 12, 2025, 3:47pm

Hi i have this code here which and ai chases you and when you enter the safe zone it should stop chasing you and find another player to chase but the thing is the ai comes very close to the safe zone part which i don’t want but idk how to do this i have tried a few things but they have not worked

here is the code:

local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")

local SAFE_ZONE_TAG = "InSafeZone"
local ENEMY = workspace["."]
local safeZone = workspace.Safezone
local DETECTION_RADIUS = 50
local maxDistance = 45


local function isPlayerVisible(enemy, target)
	local direction = (target.Position - enemy.HumanoidRootPart.Position).Unit
	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {enemy}
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude

	local raycastResult = workspace:Raycast(enemy.HumanoidRootPart.Position, direction * DETECTION_RADIUS, raycastParams)

	if raycastResult then
		local hitPart = raycastResult.Instance
		if hitPart and hitPart:IsDescendantOf(target.Parent) then
			return true
		end
	end

	return false
end

local function moveToTarget(enemy, target)
	local path = PathfindingService:CreatePath()

	path:ComputeAsync(enemy.HumanoidRootPart.Position, target.Position)
	if path.Status == Enum.PathStatus.Success then
		local waypoints = path:GetWaypoints()
		for _, waypoint in ipairs(waypoints) do
			enemy.Humanoid:MoveTo(waypoint.Position)
			local reached = enemy.Humanoid.MoveToFinished
			if not reached then
				print("Failed to reach waypoint")
				break
			end
		end
	else
		print("Path computation failed:", path.Status)
	end
end

local function detectAndChase(enemy)
	while task.wait() do
		local partsInRadius = workspace:GetPartBoundsInRadius(enemy.HumanoidRootPart.Position, DETECTION_RADIUS)

		for _, part in ipairs(partsInRadius) do
			local player = Players:GetPlayerFromCharacter(part.Parent)
			if player and player.Character and not player.Character:GetAttribute(SAFE_ZONE_TAG) then
				if isPlayerVisible(enemy, part) then
					print("Chasing player:", player.Name)
					moveToTarget(enemy, part)
				end
			end
		end
	end
end

safeZone.Touched:Connect(function(hit)
	local player = Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		player.Character:SetAttribute(SAFE_ZONE_TAG, true)
		print(player.Name, "entered safe zone")
	end
end)

safeZone.TouchEnded:Connect(function(hit)
	local player = Players:GetPlayerFromCharacter(hit.Parent)
	if player then
		player.Character:SetAttribute(SAFE_ZONE_TAG, false)
		print(player.Name, "left safe zone")
	end
end)

-- Start Detection
task.spawn(function()
	detectAndChase(ENEMY)
end)

Also here is a video of my ai:

And this is how i want my ai to work like:

I hope you guys can help me I really want to finish this

TouchEnded is very unreliable, and it can easily trigger by just jumping. You can try other methods of detection such as Raycasting and Region3

adawe678 · January 12, 2025, 3:51pm

i want to know how to stop the ai from coming any closer once I enter the safe zone I will do that change later

Zer0Wit · January 12, 2025, 3:52pm

That’s the reason why, it thinks you have left the safezone and it keeps chasing you thinking you’re still in the map

adawe678 · January 12, 2025, 3:54pm

so what should i change it to region3 or raycast

Zer0Wit · January 12, 2025, 3:55pm

Either works, or a combination of both to save server resources would be best.

adawe678 · January 12, 2025, 3:56pm

ok i will do that so you think that will fix it?

Zer0Wit · January 12, 2025, 3:57pm

Nothing else in this script would make it so it keeps chasing you, unless outside interference from a different script is changing the attribute to false

Give this a go: ZonePlus v3.2.0 | Construct dynamic zones and effectively determine players and parts within their boundaries

adawe678 · January 12, 2025, 4:21pm

hi for some reason i did this and it still goes inside of the safe zone:


local PathfindingService = game:GetService("PathfindingService")
local Players = game:GetService("Players")

local SAFE_ZONE_TAG = "InSafeZone"
local ENEMY = workspace["."]
local safeZone = workspace.Safezone
local DETECTION_RADIUS = 50
local maxDistance = 45

local function isPlayerVisible(enemy, target)
	local direction = (target.Position - enemy.HumanoidRootPart.Position).Unit
	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {enemy}
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude

	local raycastResult = workspace:Raycast(enemy.HumanoidRootPart.Position, direction * DETECTION_RADIUS, raycastParams)

	if raycastResult then
		local hitPart = raycastResult.Instance
		if hitPart and hitPart:IsDescendantOf(target.Parent) then
			return true
		end
	end

	return false
end

local function moveToTarget(enemy, target)
	local path = PathfindingService:CreatePath()

	path:ComputeAsync(enemy.HumanoidRootPart.Position, target.Position)
	if path.Status == Enum.PathStatus.Success then
		local waypoints = path:GetWaypoints()
		for _, waypoint in ipairs(waypoints) do
			enemy.Humanoid:MoveTo(waypoint.Position)
			local reached = enemy.Humanoid.MoveToFinished
			if not reached then
				print("Failed to reach waypoint")
				break
			end
		end
	else
		print("Path computation failed:", path.Status)
	end
end

local function detectAndChase(enemy)
	while task.wait() do
		local partsInRadius = workspace:GetPartBoundsInRadius(enemy.HumanoidRootPart.Position, DETECTION_RADIUS)

		for _, part in ipairs(partsInRadius) do
			local player = Players:GetPlayerFromCharacter(part.Parent)
			if player and player.Character and not player.Character:GetAttribute(SAFE_ZONE_TAG) then
				if isPlayerVisible(enemy, part) then
					print("Chasing player:", player.Name)
					moveToTarget(enemy, part)
				end
			end
		end
	end
end

local function checkSafeZonePlayers()
	local region = Region3.new(
		safeZone.Position - (safeZone.Size / 2),
		safeZone.Position + (safeZone.Size / 2)
	)

	local overlappingParts = workspace:FindPartsInRegion3(region, nil, math.huge)
	local playersInSafeZone = {}

	for _, part in ipairs(overlappingParts) do
		local player = Players:GetPlayerFromCharacter(part.Parent)
		if player then
			player.Character:SetAttribute(SAFE_ZONE_TAG, true)
			playersInSafeZone[player.Name] = true
		end
	end

	for _, player in ipairs(Players:GetPlayers()) do
		if not playersInSafeZone[player.Name] and player.Character then
			player.Character:SetAttribute(SAFE_ZONE_TAG, false)
		end
	end
end


task.spawn(function()
	while task.wait(1) do
		checkSafeZonePlayers()
	end
end)

-- Start Detection
task.spawn(function()
	detectAndChase(ENEMY)
end)

Print

player.Character:GetAttribute(SAFE_ZONE_TAG)

before chasing the player, and also make a break condition on the pathfinding so that it stops if the player’s atrribute changes

adawe678 · January 12, 2025, 4:27pm

it says false??(30charrrrrrrrrrrrrrrrrrrrrr)

adawe678 · January 12, 2025, 4:29pm

for _, part in ipairs(overlappingParts) do
		local player = Players:GetPlayerFromCharacter(part.Parent)
		if player then
			player.Character:SetAttribute(SAFE_ZONE_TAG, true)
			playersInSafeZone[player.Name] = true
			break
		end
	end

	for _, player in ipairs(Players:GetPlayers()) do
		if not playersInSafeZone[player.Name] and player.Character then
			player.Character:SetAttribute(SAFE_ZONE_TAG, false)
			break
		end

Zer0Wit · January 12, 2025, 4:29pm

It checks it every one second, does it say true after a second or so?

adawe678 · January 12, 2025, 4:30pm

no (30 30charrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrracter)

adawe678 · January 12, 2025, 4:32pm

i don’t understand why it does this

Zer0Wit · January 12, 2025, 4:33pm

Have you tried checking if its even detecting the player in the safezone? Print a message to see if it sets it to true at all

adawe678 · January 12, 2025, 4:34pm

Once it enters the safe zone? (300000000000000000000)

Zer0Wit · January 12, 2025, 4:34pm

Yes__________________ (wordfill)

adawe678 · January 12, 2025, 4:36pm

once i enter the safe zone it said false then true
