My NPC do something wried like in the gif when i do the air combo
the normal attack is fine.

And Stun script for npc
local Character = script.Parent.Parent
local Humanoid = Character:WaitForChild(“Humanoid”)
local kJ1

if Character:FindFirstChild("Stun") then
	Humanoid.WalkSpeed = 0
	Humanoid.JumpPower = 0

end	

if Character:FindFirstChild("BlockHits") and not Character:FindFirstChild("Stun") then

	Humanoid.WalkSpeed = 5
	Humanoid.JumpPower = 30

end

if Character:FindFirstChild("YouHittedEnemy") and not Character:FindFirstChild("Stun") then

	Humanoid.WalkSpeed = 12
	Humanoid.JumpPower = 0

end

if Character:FindFirstChild("GuardBreak") then

	Humanoid.WalkSpeed = 0
	Humanoid.JumpPower = 0

end

end)
script.Parent.Parent.Humanoid.Died:connect(function()
kJ1:Disconnect()
end)

Whats the “Path” Module? (limmmmmmmmmmmmt)

[taexenfimai (Evil_VegetaZ)]

it’s this module, i use this moudule becasue it made my npc smart

SimplePath - Pathfinding Module

[banner] SimplePath is an open-source pathfinding module that gives you the ability to quickly create a pathfinding script for humanoids and non-humanoids with just a few lines of code. Pathfinding is done using Roblox’s PathfindingService. This module works by using a “repetitive” approach to pathfinding. The pathfinding agent moves a more efficient path when computed repetitively instead of just once. Part of the reason why is because computing the path once doesn’t guarantee that the agen…

Use this script for now:

local NPC = script.Parent
local hrpOfNPC = npc:WaitForChild(“HumanoidRootPart”)

local plrsHit = {}

local RS = game:GetService("RunService")
local Players = game:GetService("Players")

print("Loaded vars. Canada!")

RS.RenderStepped:Connect(function()
for _,plr in pairs(Players:GetPlayers()) do
local charHRP = plr.Character:WaitForChild("HumanoidRootPart")
local mag =  (hrpOfNPC.Position - charHRP.Position).Magnitude

if mag > 10 then
--Script here!
end

end
end)

It works but he still walk like this https://gyazo.com/061f5494a3de421517539cfb51a86d74
after i did this https://gyazo.com/fa155ac33eb6cc66bba48faff8c45450

[IAmBanFor_Devforum (DevforumAccount)]

local NPC = script.Parent
local hrpOfNPC = npc:WaitForChild(“HumanoidRootPart”)

local plrsHit = {}

local RS = game:GetService("RunService")
local Players = game:GetService("Players")

print("Loaded vars. Canada!")

RS.RenderStepped:Connect(function()

local charHRP = plr.Character:WaitForChild("HumanoidRootPart")
local mag =  (hrpOfNPC.Position - charHRP.Position).Magnitude

if mag > 10 then
--Script here!
NPC.Humanoid.Walkspeed = 30
elseif mag > 5 then
--Script here!
NPC.Humanoid.Walkspeed = 16
end

end
