Npc's movement is very laggy and jittery

Help and Feedback Scripting Support
#1

The movement I used for this NPC is MoveTo in a while loop but it looks pretty glitchy and not smooth. Is there any other alternative movement methods for my NPC so that it can follow players smoothly?

#2

Set the network owner of the NPCā€™s PrimaryPart (the HumanoidRootPart if it is r15, the Head if it is r6) to nil. This will set it to the server and remove the jittering.

That didnā€™t method didnā€™t really work out for me, I just tried it but it is still glitchy and laggy. Another issue is that when I set the npcā€™s speed to 20 the npc somehow cannot catch up to my character

Can I see your full code?

while wait(.5)do

This is what i mean by npc canā€™t catch up to the character

Thats probably because its too slow. Everytime it gets to the players previous position it stops and the player is not there anymore. Try making him not stop. Also lag could be the problem try using this

game:GetService("RunService").Heartbeat:Connect(function(deltatime)
        patrol()
end)

Ok i put the while loop to wait .5 thatā€™s why thx

you can also just do lua task.wait() with nothing inside the wait and the while true do loop will fire it as fast as possible
but id use heartbeat
