NPC AI issue related to MoveToFinished

[void pasture]

So basically the ai works fine for a bit however, after a while it breaks for some reason I don't know why, Like it'll move to a few waypoints then stop for no apparent reason, the state changes work fine and there is no random state change between walk cycles

Thank you for your help

[silent folio]

    self.MoveToConnection = Humanoid.MoveToFinished:Connect(function(reached)
        if not reached then self.WalkFinished:Fire(); return end

        index += 1

        if index <= #Waypoints then
            Humanoid:MoveTo(Waypoints[index].Position)
        else
            self.WalkFinished:Fire()
        end
    end)``` pathfinding cancels part way through if the waypoint is not reached, and you are making duplicate connections to MoveToFinished event.

those duplicate connections are going to cause a lot of problems for any future pathfinding, they not able to get past the first waypoint

[void pasture]

I'm pretty sure the issue of duplicate connections I already solved by disconnecting the events

though I'll look into the cancelling part way through due to reached

but like the thing is

when if Walkfinished fires, I recompute a new path

[silent folio]

... without destroying the old MoveToConnection.

just because you put it in a variable doesnt mean the old one gets disconnected when you overwrite it

[void pasture]

I do though self:CancelWalk

am I trippin or something

[silent folio]

...not when you fire WalkFinished.

[void pasture]

Walkfinished just call walk path, and inside walk path I cancel the walk

if a connection exist

like disconnect

[silent folio]

function GrandmaObject.WalkPath(self:Grandma, Destination:Vector3)
    if not Destination then return end

    self:CancelWalk()``` there it is

missed that

[void pasture]

yup

np

its the fact that it likes move to the second waypoint, then just stops that confuses me

and before hand it works fine

its just after like 4-5 cycles

its stops working

[silent folio]

increase the agent radius

[void pasture]

ok I will try, but how would that help?

[silent folio]

likely getting jammed on a wall or something

[void pasture]

its not that, like its basically just constantly traversing a house and what not, and even if it gets blocked it should recompute a path, and besides after the 4-5 cycles the problems keeps on repeating itself

but anyways trying right now

I'll tell you if it works

the ai works similar to granny

[silent folio]

i remember having a similar issue with my npc

cant remember what i did to fix it, but one of the symptoms was the waypoint visualizer kept rising up out of the ground and into the air, eventually becoming unreachable

[void pasture]

oh ye wait let me visualize this

I didn't try that

let me see

[silent folio]

i also think you may need more handling around lua if Path.Status ~= Enum.PathStatus.Success then return end here add a warn

particularly while devving

[void pasture]

Nope it creates the waypoints and they are all on the ground however it walks for a few seconds then just stops for some reason

[void pasture]

oh ye sure

the script is still a work in progress, there still some stuff I want to refine but for now I just want to get this issue over with

ok so I think I noticed something

The path computes and what not

and the npc will continue walking that path

however will stop near an object whether its a wall or what not

I still don't get why it works before though

then stops randomly

[silent folio]

ya increase agent radius

so it doesnt get too close to wall

also review navmesh

use the roblox navmesh visualizer thingy, google the setting name

i suspect it may be trying to pathfind through a wall

or over it, rather

pathfinder tricky thing, lots of possible issues

[void pasture]

I use the navmesh visualiser, the path is computed and looks completely fine

[silent folio]

it could still be your state machine

[void pasture]

not over anything

I don't think I print whenever there is a state change

[silent folio]

could try moving the npc while the game is running to see what happens, on the server ofc

[void pasture]

Oh ye sure imma try that

[silent folio]

debugging bruuh

[void pasture]

ikr, its so annoying

like i've been on this for like 3 days

[silent folio]

and you didn't try that already?

[void pasture]

OH

moving it

will

make it work again

[void pasture]

nope 😭

[silent folio]

so its probably just getting jammed on something

keep trialing stuff

specially now you have clear, easily reproducible symptom

actually thinking about it, it could also be network ownership

    for i,v:BasePart in self.Character:GetDescendants() do
        if v:IsA("BasePart") then v:SetNetworkOwner(nil) end
    end``` looks fine

[void pasture]

yup I had that issue a while ago but I fixed it

ok now sometimes it walks to third and 4th waypoint, however it like stutters for some reason

Oh one more thing @silent folio , you think this is S2 or nah?

[silent folio]

you are struggling to debug it, what do you think

[void pasture]

okay vro

[silent folio]

can't just look right, has to be right too

[void pasture]

I think after I fix it though should be worth S2, got alot of things built into it and what not but I'll still see, I don't want to make an application too soon

thanks for your help, if you have any more ideas please be sure to share them

nah I lied

ye I think its a network owner ship issue

I used the Network Owner thing in the settings

and for some reason the character parts become are green

which in the docs means that they are owned by my character
