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…
Yeah a video will be helpful to find out the problem.
I might just use my regular one which uses :MoveTo with no jump if there is no fix for it :/
Oh ok, I will send a vid, hold on.
It isn’t doing it now… how weird!!
Also I got a message in output saying “Failing to check if player is in group”
Oh it isn’t doing it now bc I changed to the regular follow, whoops
That isn’t related to the script, its a problem with Roblox’s core scripts or Roblox’s servers, or another script.

Ok, let me send a video once again :/
He, like, lags when he turns…
