Hello, i’ve been following this tutorial, i finished the script and noticed that the Pathfinding NPC acts weird while following the player, i have two problems:
The Pathfinding NPC is choppy and doesn’t jump when there’s an obstacle in the way, instead it stops for about 5 - 10 seconds before doing anything. (However it’s able to detect the best way to find the player… unless it gets stuck, then it won’t react until the time given above).
The Pathfinding NPC can’t outrun the player, no matter how much speed i give it.
These problems are just the opposite of what i intended to achieve, which was for the Pathfinding NPC to be quick and outrun the player, while constantly following them and not getting stuck.
Here’s the Pathfinding script:
local root = script.Parent.HumanoidRootPart
root:SetNetworkOwner(nil)
local zombie = script.Parent.Zombie
function findTarget()
local dist = 200
local target = nil
for i, v in pairs(workspace:GetChildren()) do
local hum = v:FindFirstChild("Humanoid")
local humTarget = v:FindFirstChild("HumanoidRootPart")
if hum and humTarget then
if (humTarget.Position - root.Position).magnitude < dist and hum.Health > 0 then
dist = (humTarget.Position - root.Position).magnitude
target = humTarget
if (root.Position - target.Position).magnitude < 6 then
target.Parent.Humanoid:TakeDamage(20)
end
end
end
end
return target
end
while wait() do
local humTarget = findTarget()
if humTarget then
local ray = Ray.new(root.Position,(humTarget.Position - root.Position).Unit * 200)
local hit,position = workspace:FindPartOnRayWithIgnoreList(ray, {script.Parent})
if hit then
if hit:IsDescendantOf(humTarget.Parent) then
zombie:MoveTo(humTarget.Position)
else
path = game:GetService("PathfindingService"):CreatePath()
path:ComputeAsync(root.Position, humTarget.Position)
points = path:GetWaypoints()
if path.Status == Enum.PathStatus.Success then
for i, v in pairs(points) do
zombie:MoveTo(v.Position)
zombie.MoveToFinished:Wait()
if v.Action == Enum.PathWaypointAction.Jump then
zombie.Jump = true
end
if (points[#points].Position - humTarget.Position).magnitude > 15 then
break
end
end
else
zombie:MoveTo(humTarget.Position)
end
end
end
end
end
One possible solution i tried was to replace every zombie:MoveTo(humTarget.Position) with zombie:MoveTo(humTarget.Position, humTarget) which actually kind of worked, it could outrun the player (Still couldn’t jump when needed) but i’m not sure if it’s actually not the way i’m intended to do it at all.
I also replaced wait(1) and wait(2) with wait() and it helped with the choppiness, however now the way to damage i added is way too fast and almost instantly kills the player.
Please tell me if this is the wrong category and if you didn’t understand something.
i did, but same thing happens, it still can’t outrun, i’m guessing it is since pathfinding finds a position, so it’s constantly finding it and it’s the only way it can move towards the player.
Edited the post and it seems like the link works now, thanks for pointing that out.
Changing the walkspeed of the Zombie on any way doesn’t work, it will reach the player faster, but it will have the same relative speed when it’s close.
So, the new MoveTo loop section would look like this:
for i, v in pairs(points) do
zombie:MoveTo(v.Position)
--zombie.MoveToFinished:Wait() --keep incase it's fixed in the future
repeat
distance = (v.Position - root.Position).magnitude
wait()
until
distance <= 6
if v.Action == Enum.PathWaypointAction.Jump then
zombie.Jump = true
end
if (points[#points].Position - humTarget.Position).magnitude > 15 then
break
end
end
Now, the attacking part of the script can get complex. I think it should be a separate function that detects when the zombie’s body is touched, then it deals damage to the humanoid that touched it.
I solved the attack part adding a coroutine with a loop, the main problem i’m having right now is that the Zombie doesn’t jump when it’s needed to, and it seems like it’s zombie.MoveToFinished:Wait(), without it the Zombie can jump obstacles easily, however, when it’s time to find the player behind a wall and such it gets stuck, so removing it doesn’t seem viable, not sure what else i can do.
Have you tried setting the agent parameters when defining the pathfindingservice?
local pfs = game:GetService("PathfindingService"):CreatePath({AgentRadius = 3; AgentHeight = 5}
AgentRadius is basically the distance they path from walls.
AgentHeight is how tall the NPC is; any space under 5 studs tall won’t be calculated like underneath stairs.
I removed the “zombie:MoveToFinished:Wait()” line in my script.
You could also try to lower the distance before it recalculates the path.
if (points[#points].Position - humTarget.Position).magnitude > 10 then --this
break
end
Solved it, had to move path.Status == Enum.PathStatus.Success to another place, hope i don’t get any more problems with this.
for i, v in pairs(points) do
if v.Action == Enum.PathWaypointAction.Walk then
zombie:MoveTo(v.Position)
else
zombie.Jump = true
zombie:MoveTo(v.Position)
end
if path.Status == Enum.PathStatus.Success then
zombie.MoveToFinished:Wait()
else
zombie:MoveTo(plrTarget.Position)
end
if (points[#points].Position - plrTarget.Position).magnitude > 10 then
break
end
end
