What do you I to achieve? No stopping delay

What is the issue?

Video on the issue:

I want the Zombie to continue walking no matter what.

Pathfinding Script:

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

local zombieDamage = 10 --attack damage dealed to player
local zombieAttackCd = 3 --cooldown time before next attack

local rig = script.Parent

local function checkForCharacter(character)
	local rayOrigin = rig:FindFirstChild("HumanoidRootPart").Position
	local rayDirection = (character.HumanoidRootPart.Position - rayOrigin).Unit * 40
	
	local raycastResult = workspace:Raycast(rayOrigin, rayDirection, RaycastParams.new())

	if raycastResult then
		local raycastInstance = raycastResult.Instance
		if raycastInstance:IsDescendantOf(character) then
			return true
		end
	else
		return false
	end
end

local function findNearestPlayer()
	local players = Players:GetPlayers()
	local nearestPlayer = nil
	local maxDistance = 40
	
	for _, player in pairs(players) do
		if player.Character ~= nil then
			local targetCharacter = player.Character
			local distance = (rig.HumanoidRootPart.Position - targetCharacter.HumanoidRootPart.Position).Magnitude
			
			if distance < maxDistance and checkForCharacter(targetCharacter) then
				nearestPlayer = targetCharacter
				maxDistance = distance
			end
		end
	end
	return nearestPlayer
end

local function attack(character)
	local cdTime = zombieAttackCd
	local db = false

	local distance = (rig.HumanoidRootPart.Position - character.HumanoidRootPart.Position).Magnitude

	if distance > 5 then
		rig.Humanoid:MoveTo(character.HumanoidRootPart.Position)
	else
		if db == false then
			character.Humanoid.Health -= zombieDamage
		end
		db = true
		task.wait(cdTime)
	end
end

local function calculatePath(destination)
	local agentParams = {
		["AgentHeight"] = 5,
		["AgentRadius"] = 4,
		["AgentCanJump"] = false
	}
	
	local path = PathfindingService:CreatePath(agentParams)
	path:ComputeAsync(rig.HumanoidRootPart.Position, destination)
	return path
end

local function walkToDestination(destination)
	local path = calculatePath(destination)
	
	if path.Status == Enum.PathStatus.Success then
		for _, waypoint in pairs(path:GetWaypoints()) do
			local nearestPlayer = findNearestPlayer()
			if nearestPlayer then
				attack(nearestPlayer)
				break
			else
				rig.Humanoid:MoveTo(waypoint.Position)
				rig.Humanoid.MoveToFinished:Wait()
			end
		end
	else
		rig.Humanoid:MoveTo(destination - (rig.HumanoidRootPart.CFrame.LookVector * 10))
	end
end

local function patrol()
	local waypoints = workspace.Waypoints:GetChildren()
	local randomNumber = math.random(1, #waypoints)
	
	walkToDestination(waypoints[randomNumber].Position)
end

while task.wait(.01) do
	patrol()
	if rig.Humanoid.Health == 0 then
		rig:Destroy()
	end
end

Thanks for any help and you’re time! :happy4:

I fixed this script by moving the db variable outside of the attack function, and also by replacing task.wait(cdTime) with

task.defer(function()
	task.wait(cdTime)
	db = false
end)

The Completed Code is below:

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

local zombieDamage = 10 --attack damage dealed to player
local zombieAttackCd = 3 --cooldown time before next attack
local db = false
local rig = script.Parent

local function checkForCharacter(character)
	local rayOrigin = rig:FindFirstChild("HumanoidRootPart").Position
	local rayDirection = (character.HumanoidRootPart.Position - rayOrigin).Unit * 40

	local raycastResult = workspace:Raycast(rayOrigin, rayDirection, RaycastParams.new())

	if raycastResult then
		local raycastInstance = raycastResult.Instance
		if raycastInstance:IsDescendantOf(character) then
			return true
		end
	else
		return false
	end
end

local function findNearestPlayer()
	local players = Players:GetPlayers()
	local nearestPlayer = nil
	local maxDistance = 40

	for _, player in pairs(players) do
		if player.Character ~= nil then
			local targetCharacter = player.Character
			local distance = (rig.HumanoidRootPart.Position - targetCharacter.HumanoidRootPart.Position).Magnitude

			if distance < maxDistance and checkForCharacter(targetCharacter) then
				nearestPlayer = targetCharacter
				maxDistance = distance
			end
		end
	end
	return nearestPlayer
end

local function attack(character)
	local cdTime = zombieAttackCd
	local distance = (rig.HumanoidRootPart.Position - character.HumanoidRootPart.Position).Magnitude

	if distance > 5 then
		rig.Humanoid:MoveTo(character.HumanoidRootPart.Position)
	else
		if db == false then
			character.Humanoid.Health -= zombieDamage
		end
		db = true
		
		task.defer(function()
			task.wait(cdTime)
			db = false
			
		end)
		
	end
end

local function calculatePath(destination)
	local agentParams = {
		["AgentHeight"] = 5,
		["AgentRadius"] = 4,
		["AgentCanJump"] = false
	}

	local path = PathfindingService:CreatePath(agentParams)
	path:ComputeAsync(rig.HumanoidRootPart.Position, destination)
	return path
end

local function walkToDestination(destination)
	local path = calculatePath(destination)

	if path.Status == Enum.PathStatus.Success then
		for _, waypoint in pairs(path:GetWaypoints()) do
			local nearestPlayer = findNearestPlayer()
			if nearestPlayer then
				attack(nearestPlayer)
				break
			else
				rig.Humanoid:MoveTo(waypoint.Position)
				rig.Humanoid.MoveToFinished:Wait()
			end
		end
	else
		rig.Humanoid:MoveTo(destination - (rig.HumanoidRootPart.CFrame.LookVector * 10))
	end
end

local function patrol()
	local waypoints = workspace.Waypoints:GetChildren()
	local randomNumber = math.random(1, #waypoints)

	walkToDestination(waypoints[randomNumber].Position)
end

while task.wait(.01) do
	patrol()
	if rig.Humanoid.Health == 0 then
		rig:Destroy()
	end
end

Just tested it in game and it works., good luck on your zombie AI!

That was great! It worked!

But one more thing can you help me with this weird turning?

Video:

#4

I’m not sure but my guess is it could be something to do with your waypoint system as when I run around a zombie in game the same way you did, with only one way point in Waypoints he sometimes unlocks off of me and goes for the waypoint instead.

#5

Thinking about it im probaly at the border of the radius (MaxDistance) so ye it decides do go back the the waypoint but really quickly i walk back into the radius making him choose hes Rival (Me) >:D

#6

I extended the MaxDistance, but technily it would be the same but ima roll with it :roller_skate:
