My path is being updated constantly. This tutorial doesn’t seem to have anything about it.
Plus this was made in 2020 so the entire script is now using deprecated methods.
(my mistake, not 2020, 2022, yet still)
I just finished reading it, quite long. The part I’m referring to is under the “Bot AI Chasing” section. I suggest reading the whole thing but here’s the relevant bit:
Now that I’ve explained the reasons why, it’s time to create a new script. The flow of the script is simple. Everytime the while loop runs, it will call a function which tells the script to detect any closest player to the bot itself. If it managed to find one, we will tell the script to compute the path to it, and make our bot to only loop/walk through the second or third waypoint of the path before ending the function. Then this whole sequence would be repeated until our bot touches the player and makes the player die. Simple enough.
I personally haven’t really ran into an error where the AI chaser becomes jittery. In the zombie game I’m currently working on, the zombies may pause for a second when the player moves too fast, then just proceed as normal. It uses the same logic here (walk to the 2nd-3rd waypoint, then recalculate, repeat until all players dead). I’m not really sure what your case looks like, a video would be helpful.
Could you try to declare the Follow() function whenever the Closest Target moves? set a listener to the AssemblyLinearVelocity Property.

Can you explain better?
I’ve played around a bit, and I am satisfied with this script:

end)

He is so OP now. I regret calling him annoying. I can’t run away from him now. May he forgive me.
(He can’t jump, but in my game you won’t be able to jump either, so it is not necessary. You can add jumping ability if you’d like to.)
