It has only 1 waypoint too which is where the npc starts moving.
Just follow the tutorial mentioned by @SpacialEthanRB, but use the player’s humanoidRootPart as the destination.
I did! Did you not see the code I sent? Please help 
Here is the code again:
local npcHRP = script.Parent.HumanoidRootPart
local PathFindingServ = game:GetService("PathfindingService")
local npcH = script.Parent.Humanoid
local npcT = script.Parent.Torso
local function GetNearestPlayer(minimumDistance)
local closestMagnitude = minimumDistance or math.huge
--minimumDistance is a number in studs
local closestPlayer
for i,v in next, game.Players:GetPlayers() do
local Character = v.Character
if (Character) then
local humanoid = Character.Humanoid
local HRP = Character.HumanoidRootPart
if (humanoid.Health > 0) then
local mag = (npcHRP.Position - HRP.Position).Magnitude
if (mag <= closestMagnitude) then
closestPlayer = v
closestMagnitude = mag
end
end
end
end
return closestPlayer
end
while wait() do
local nearPlr = GetNearestPlayer(70)
pcall(function()
local path = PathFindingServ:CreatePath()
path:ComputeAsync(npcT.Position, nearPlr.Character.HumanoidRootPart.Position)
local waypoints = path:GetWaypoints()
for _, wp in pairs(waypoints) do
local part = Instance.new("Part")
if wp.Action == Enum.PathWaypointAction.Jump then
script.Parent.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
end
print(wp.Action)
script.Parent.Humanoid:Move(wp.Position)
script.Parent.Humanoid.MoveToFinished:Wait()
end
end)
end
I have posted a new post for this issue, see this: PathfindingService is making NPC jump off the edge of map instead of chasing player
You’re doing Humanoid:Move(wp.Position), You should be doing Humanoid:MoveTo(wp.Position)
Also, Humanoid.MoveToFinished:Wait() ends up studdering, you might wanna look into using magnitude instead of .MoveToFinished.

Ah thanks, how would I use the magnitude though?
New script but makes the NPC all juttery and delayed:
local npcHRP = script.Parent.HumanoidRootPart
local PathFindingServ = game:GetService("PathfindingService")
local npcH = script.Parent.Humanoid
local npcT = script.Parent.Torso
local function GetNearestPlayer(minimumDistance)
local closestMagnitude = minimumDistance or math.huge
--minimumDistance is a number in studs
local closestPlayer
for i,v in next, game.Players:GetPlayers() do
local Character = v.Character
if (Character) then
local humanoid = Character.Humanoid
local HRP = Character.HumanoidRootPart
if (humanoid.Health > 0) then
local mag = (npcHRP.Position - HRP.Position).Magnitude
if (mag <= closestMagnitude) then
closestPlayer = v
closestMagnitude = mag
end
end
end
end
return closestPlayer
end
while wait() do
local nearPlr = GetNearestPlayer(70)
pcall(function()
local path = PathFindingServ:CreatePath()
path:ComputeAsync(npcT.Position, nearPlr.Character.HumanoidRootPart.Position)
local waypoints = path:GetWaypoints()
for _, wp in pairs(waypoints) do
local part = Instance.new("Part")
if wp.Action == Enum.PathWaypointAction.Jump then
script.Parent.Humanoid.Jump = true
end
print(wp.Action)
script.Parent.Humanoid:MoveTo(wp.Position)
wait(0.05)
end
end)
end
When he is in water, he doesn’t jump to come out of it.
And when it prints that he needs to jump, he doesn’t jump. (he makes me lag alot too)
I have a fairly advanced Zombie AI with pathfinding that I believe you may find useful since your NPC seems to be similar to a zombie. But the script will probably need some modifications of course.

Just put this script inside the NPC and it should work, you may need to make some modifications to it. I could probably explain how it works but I don’t have the time right now.
The script is open-source so anyone can use it if they want.

Wow that is too confusing for me. I can’t use this or I will just be so confused.
Well I might as well use it or i wouldn’t have a good game.
How do I change the scanning distance?
I know it is frustrating when you don’t know the logic behind the code. But sometimes you have to use it until you get better and finally start to understand how it works. It happens with me as well.
It jutters alot when it moves, how can I fix it.
I don’t know what you are talking about it works perfect for me.

Oh for me it sometimes stops for a sec then starts again.
Which makes it delay and lag - so to speek.
I would send a video but :/
I dunno…
