Trying to make npc chase player at a game that contains alot of parts
What is the issue? Include screenshots / videos if possible!
the npc moves very slowly
heres the clip:
Please help!
What type of movement method for the npc’s are you using?
Sorry, I don’t understand what you meant by movement method, what is movement method?
are there any properties in the workspace that could change this?
I think they mean what are you doing to move them.
Like tweens, moveto, etc.
I used the MoveTo method using PathFindingService. The problem is my game contains a lot of parts and making the chaser movements slow, Is there any solution regarding this problem?
What if you use a tween for each waypoint? (And wait for the tween to end before starting the new one)
Used tween for each waypoint, but it didn’t seems to work, the NPC is just standing still at the spawn, Is there another way to fix this?
you should probably only use moveTo when the npc is very close to the player. And use path finding service when the npc is far away from the player, too far to just run straight toward the player. Another thing could be that you have way too many npcs tryikng to use path finding service at once. So either cut on the number of npcs or try and slow down or limit how many npcs are using path finding service at once.
big edit:
i just remembered frorm my time working with PathFinding Service that using MoveTo alot of times can cause this effect where the npcs pause for a moment before moving again. Its a weird bug that you cant fix but can work around. The easiest work around is to make the waypoint spacing alot bigger that way the npcs have a longer distance to travel before calling on moveTo again. A harder and more risky work around would be to ditch the moveTo function entirely and use a repeat loop along with runservice to manually replicate the moveTo function. however you don’t seem like an experienced programmer so id say you stay away from the hard way. It can cause memory leaks or just be very hard to get to work. Try increasing the way point spacing
Already tried increasing the waypoint spacing but the results are still the same, it moves smoothly but EXTREMELY SLOW, And heres the clip:
As i said earlier, it moves very slow when my game contains a lot of parts, and is there a properties that i could change to fix this, i think this is unfixable tho.
please help!
idk man you might have to use other tools to fix this
ok you need to give us a more detailed description of what is going on in your game. how many parts are unanchored, now many npcs, how often are they using path finding service, how are they using path fi ding service. this is your game, we know absolutely nothing. saying there are alot of parts is not enough for us to help.
with that high ping, it’s probably because you’re doing too much in what I’d assume is a Runservice function. Try maybe sharing your code so that we can actually see what’s happening.
the unanchored parts are only the npcs
3 npc’s.
i used pathfinding service really often (this might be the problem)
this is the code:
local nrstt
while wait() do
if RTB.Value == false then
nrstt = GetTorso(hroot.Position)
if nrstt ~= nil and human.Health > 0 and game.Players:GetPlayerFromCharacter(nrstt.Parent):WaitForChild("Attackable").Value == true then -- if player detected
print("theres human")
vars.Wandering.Value = false
vars.Chasing.Value = true
local function checkw(t)
local ci = 3
if ci > #t then
ci = 3
end
if t[ci] == nil and ci < #t then
repeat ci = ci + 1 wait() until t[ci] ~= nil
return Vector3.new(1,0,0) + t[ci]
else
ci = 3
return t[ci]
end
end
path = pfs:FindPathAsync(hroot.Position, nrstt.Position)
waypoint = path:GetWaypoints()
if path and waypoint or checkw(waypoint) then
if checkw(waypoint) ~= nil and checkw(waypoint).Action == Enum.PathWaypointAction.Walk then
human:MoveTo( checkw(waypoint).Position )
human.Jump = false
end
if checkw(waypoint) ~= nil and checkw(waypoint).Action == Enum.PathWaypointAction.Jump then
connection = human.Changed:connect(function()
human.Jump = true
end)
human:MoveTo( waypoint[4].Position )
end
if connection then
connection:Disconnect()
end
else
for i = 3, #waypoint do
human:MoveTo( waypoint[i].Position )
end
end
path = nil
waypoint = nil
elseif nrstt == nil then
vars.Wandering.Value = true
vars.Chasing.Value = false
CchaseName = nil
path = nil
waypoint = nil
walkRandomly()
vars.Wandering.Value = false
end
end
end
please help 
I’d first start off by changing the While loop because that’s probably the main source of lag right there, you could probably have this firing once the player is moving, so just get the localplayer hrp and check for movement.
What might also be an issue, just from a quick glance, is that you’re setting your path and waypoint to nil, when the humanoids probably haven’t reached their destination yet. I could be completely wrong but I’d just put a couple of prints within the code to see if everything that’s supposed to be happening is actually happening.
I’m not really too good with the natural Pathfinding of roblox, so I could be wrong and that’s how you’re normally supposed to do it.
Also, if this is being fired from the server, I’d check to see how much power is being used to run this script, you can see the consumption by pressing Ctrl + F7 while in playtesting to see.
yeah this while loop is running more than once every frame. Its almost running as fast as possible so youre crushing the server by trying to find thousands of paths each second. The roblox page has a great tutourial and sample code that probably works exactly as youd need it to. It checks to see if the npc has finished the current path before starting a new one. Its what i used when i first started on path finding service, it was a great help.
