Trying to modify a pathfinding enemy script, can anyone help?

[souflee]

Hey there,
A while ago I’ve followed (and completed) a tutorial for a pathfinding, randomly walking enemy. Here’s the link to said tutorial:

Roblox - Zombie Advanced AI Tutorial (Pathfinding, Custom Animations, Raycasting)

However, what I’m trying to do now is to have the pathfinding NPC head from point A to point C, and still detect when it should attack a nearby player. Currently all the script achieves is heading from point A- to C, it doesn’t seem to detect when a player is nearby, and when it should attack accordingly.

I haven’t tried much yet as I couldn’t find all too much info for this topic, but any help is greatly appreciated!

Here’s the code:

math.randomseed(tick())

local myHuman = script.Parent:WaitForChild("Humanoid")
local myRoot = script.Parent:WaitForChild("HumanoidRootPart")
local head = script.Parent:WaitForChild("Head")
local lowerTorso = script.Parent:WaitForChild("LowerTorso")

local walkAnim = script.Parent.Walk
local walkAnimPlay = myHuman:LoadAnimation(walkAnim)

local idleAnim = script.Parent.Idle
local idleAnimPlay = myHuman:LoadAnimation(idleAnim)

local holdWeapon = script.Parent.HoldWeapon
local holdWeaponPlay = myHuman:LoadAnimation(holdWeapon)

holdWeaponPlay:Play()

local clone = script.Parent:Clone()

function walkRandomly()
	
	local goalA = script.Parent.Point1
	local goalB = script.Parent.Point2
	local goalC = script.Parent.Point3
	
repeat
	idleAnimPlay:Stop()
	myHuman:MoveTo(goalA.Position)
	walkAnimPlay:Play()
	myHuman.MoveToFinished:Wait()
	idleAnimPlay:Play()
	wait(math.random(2,6))
	idleAnimPlay:Stop()
	myHuman:MoveTo(goalB.Position)
	walkAnimPlay:Play()
	myHuman.MoveToFinished:Wait()
	idleAnimPlay:Play()
	wait(math.random(2,6))
	idleAnimPlay:Stop()
	myHuman:MoveTo(goalC.Position)
	walkAnimPlay:Play()
	myHuman.MoveToFinished:Wait()
	idleAnimPlay:Play()
	wait(math.random(2,6))
		
	until
	script.Parent.EnemyInSight.Value == true
end

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
			end
			myHuman:MoveTo(waypoint.Position)
			local timeOut = myHuman.MoveToFinished:Wait(1)
			if not timeOut then
				myHuman.Jump = true
			--	print("Path too long!")
				script.Parent.EnemyInSight.Value = false
				findPath(target)
				break
			end
			if checkSight(target) then
				repeat
				---	print("Moving directly to the target")
					-- enemyInSight = true
					myHuman:MoveTo(target.Position)
					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
				--				print("Target has moved, generating new path")
			if script.Parent.EnemyInSight.Value == false then
			script.Parent.EnemyInSight.Value = true
				findPath(target)
				break
			end
		end
	end
end
end

function checkSight(target)
	local ray = Ray.new(myRoot.Position, (target.Position - myRoot.Position).Unit * 40)
	local hit,position = workspace:FindPartOnRayWithIgnoreList(ray, {script.Parent})
	if hit then
		if hit:IsDescendantOf(target.Parent) and math.abs(hit.Position.Y - myRoot.Position.Y) < 3 then
			script.Parent.EnemyInSight.Value = true
			return true
		end
	end
	return false
end

function findTarget()
	local dist = script.Parent.Distance.Value
	local target = nil
	local potentialTargets = {}
	local seeTargets = {}
	for i,v in ipairs(workspace:GetChildren()) do
		local human = v:FindFirstChild("Humanoid")
		local torso = v:FindFirstChild("Torso") or v:FindFirstChild("HumanoidRootPart")
		if human and torso and v.Name ~= script.Parent.Name then
			if (myRoot.Position - torso.Position).magnitude < dist and human.Health > 0 and human.NPC.Value == false then
				table.insert(potentialTargets,torso)
			end
		end
	end
	if #potentialTargets > 0 then
		for i,v in ipairs(potentialTargets) do
			if checkSight(v) then
				table.insert(seeTargets, v)
			elseif #seeTargets == 0 and (myRoot.Position - v.Position).magnitude < dist then
				script.Parent.EnemyInSight.Value = false
				walkRandomly()
			end
		end
	end
	if #seeTargets > 0 then
		dist = 30
		for i,v in ipairs(seeTargets) do
			if (myRoot.Position - v.Position).magnitude < dist then
				target = v
				dist = (myRoot.Position - v.Position).magnitude
			end
		end
	end
	if target then
		if math.random(20) == 1 then
			head.Quote1:Play()
		end
	end
	return target
end


lowerTorso.Touched:Connect(function(obj)
	if not obj.Parent:FindFirstChild("Humanoid") then
		myHuman.Jump = true
	end
end)

function main()
	local target = findTarget()
	if target then
		myHuman.WalkSpeed = script.Parent.ChaseSpeed.Value
		walkAnimPlay:Play()
		findPath(target)
	else
		myHuman.WalkSpeed = script.Parent.WanderSpeed.Value
		script.Parent.EnemyInSight.Value = false
		walkRandomly()
	end
end

while wait(0.1) do
	if myHuman.Health < 1 then
		break
	end
	main()
end

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.
