Zombie pathfinding

Sasha899_2017 · March 1, 2024, 7:01pm

What do you want to achieve? I want to make it so that the zombie initially goes to the desk, but if the attackValue changes to true, then the zombie would go to the player
What is the issue? I need the zombie to follow the player after the Attack Player has changed.Value to true, and in other cases went to the part
What solutions have you tried so far? I checked other roblox forums

Attack Player located in zombie.Configs as IntValue
I used a translator, so there may be mistakes in my text, ask questions if you need

local PathfindingService = game:GetService("PathfindingService")
local hum = script.Parent:WaitForChild("Humanoid")
local torso = script.Parent:WaitForChild("Torso")
local path
local target

function findTarget()
	local result
	local GetPart

	if script.Parent.Configs.AttackPlayer.Value then
		for i,v in pairs(workspace:GetChildren()) do
			if v:FindFirstChildOfClass("Humanoid") then
				GetPart = v.PrimaryPart
			end
		end
	else
		GetPart = workspace.Map.Truck.PrimaryPart
	end

	return GetPart
end

while task.wait(0.1) do
	target = findTarget()
	
	if target ~= nil then
		path = PathfindingService:CreatePath()
		path:ComputeAsync(torso.Position, target.Position)
		local waypoints = path:GetWaypoints()

		for i,v in pairs(waypoints) do
			hum:MoveTo(v.Position)

			if v.Action == Enum.PathWaypointAction.Jump then
				hum:ChangeState(Enum.HumanoidStateType.Jumping)
			end

			hum.MoveToFinished:Wait()
		end
	end
end

You can just attach a function to the :PropertyChangedSignal and do whatever you need to do there. I don’t see why Attack Player needs to be an IntValue though, if anything it should be a stringValue but I don’t know your project structure. Please correct me if I misunderstood your problem.

Sasha899_2017 · March 1, 2024, 7:17pm

Oh yes, I wrote it wrong, I have a boolvalue, I would try your option, but the problem is that the zombie waits until it completes the movement to a certain point, and the player can attack at any moment. Either I didn’t quite understand you either, correct me if that’s not the case.

Sasha899_2017 · March 1, 2024, 7:19pm

Thanks for the help, but unfortunately in my case, a zombie always knows where to go, so far I have problems with how to redirect zombies from the part to the player

erlsnt · March 1, 2024, 7:29pm

It’s because of the function inside the while loop

hum.MoveToFinished:Wait()

put an else there and then place

for i,v in pairs(waypoints) do
			hum:MoveTo(v.Position)

			if v.Action == Enum.PathWaypointAction.Jump then
				hum:ChangeState(Enum.HumanoidStateType.Jumping)
			end

			hum.MoveToFinished:Wait()
		end

Sasha899_2017 · March 1, 2024, 7:32pm

Can you explaint please, else for what? I have only one if, and its just checking target

erlsnt · March 1, 2024, 7:32pm

Forgot to add

if target == nil then
		path = PathfindingService:CreatePath()
		path:ComputeAsync(torso.Position, target.Position)
		local waypoints = path:GetWaypoints()

		for i,v in pairs(waypoints) do
			hum:MoveTo(v.Position)

			if v.Action == Enum.PathWaypointAction.Jump then
				hum:ChangeState(Enum.HumanoidStateType.Jumping)
			end

			hum.MoveToFinished:Wait()
		end
else
findTarget()
	end

It didnt help , zombie stopped attacking

I used 2 pathfinding services here really

One for the chase and one for the “truck” that it’s going to. I would recommend you use random points. You shouldn’t just use one.

It worked for me so it should work for you; just try it in a new line

erlsnt · March 1, 2024, 8:06pm

As for “random” points I mean it like;

local function Move()
	local Waypoints = game.Workspace:FindFirstChild("Waypoints") -- make a folder like this and then insert your points here
	local Points = Waypoints:GetChildren()	
	local randompoint = math.random(1, #points)	
	wait()
	moveTo(points[randompoint])
end

while task.wait() do
	Move()
end

Sasha899_2017 · March 1, 2024, 8:15pm

Yes, it really works, but sometimes zombie using cheats and jump inf times

Remove the jump detection on the function since it’s doing that

It’s already on another function so it loops through

Sasha899_2017 · March 1, 2024, 8:33pm

i think i have some bugs with it https://youtu.be/CTBjD-Gv8Mg

erlsnt · March 1, 2024, 8:38pm

Oh yes, when it attacks I made it so it teleports to the player.

Just remove the

	Model:MoveTo(Target.HumanoidRootPart.Position)

on the attack local function atk(Target, destination) function and then change the Distance to 4

he is still jumping, maybe this can help you, or maybe i did something wrong

You didn’t remove it

local function atk(Target, destination)
	local Value = Values.AttackPlayer.Value
	if Value == true then
		local Distance = (Model.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude

* for i, v in pairs (pathy:GetWaypoints()) do *
* if v.Action == Enum.PathWaypointAction.Jump then --remove these
*Humanoid:ChangeState(Enum.HumanoidStateType.Jumping) *
					end
					Humanoid:MoveTo(v.Position)
				end

			else
				print("Path Unsuccesful")
			end

		else	

			Target.Humanoid.Health -= 15
			Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			Humanoid:MoveTo(script.Parent.HumanoidRootPart.Position - (script.Parent.HumanoidRootPart.CFrame.LookVector * 100))
		end
	else
		warn("Value not true")
	end
end

I see you removed the other one too, maybe that’s why. Another solution is you can just turn the true into false on the pathGet() value

Sasha899_2017 · March 1, 2024, 8:58pm

i think i dont understanding something, i deleted strings in * *, but in Humanoid:MoveTo(v.Position) v isnt defined
For now i have this one

	local Value = Values.AttackPlayer.Value
	if Value == true then
		local Distance = (Model.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude
		if Distance > 4 then
			local pathy = pathGet(destination)
			if pathy.Status == Enum.PathStatus.Success then
				Humanoid:MoveTo(v.Position)
			else
				print("Path Unsuccesful")
			end

		else	

			Target.Humanoid.Health -= 15
			Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			Humanoid:MoveTo(script.Parent.HumanoidRootPart.Position - (script.Parent.HumanoidRootPart.CFrame.LookVector * 100))
		end
	else
		warn("Value not true")
	end
end

but v still not defined

erlsnt · March 1, 2024, 9:03pm

My fault, you were just supposed to remove the

 if v.Action == Enum.PathWaypointAction.Jump then 
*Humanoid:ChangeState(Enum.HumanoidStateType.Jumping) *
					end

It should look like this at the end;

local function atk(Target, destination)
	local Value = Values.AttackPlayer.Value
	if Value == true then
		local Distance = (Model.HumanoidRootPart.Position - Target.HumanoidRootPart.Position).Magnitude
		if Distance > 4 then
			local pathy = pathGet(destination)
			if pathy.Status == Enum.PathStatus.Success then
*for i, v in pairs (pathy:GetWaypoints()) do 

					Humanoid:MoveTo(v.Position)
				end

			else
				print("Path Unsuccesful")
			end

		else	

			Target.Humanoid.Health -= 15
			Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			Humanoid:MoveTo(script.Parent.HumanoidRootPart.Position - (script.Parent.HumanoidRootPart.CFrame.LookVector * 100))

yea, it works but zombie cant attack truck and still jumping but in another way
