As title mentions. I'm trying to remove AI from specific mobs when they spawn

Hi I'm AutoThreadBot! Don't mind me, I'll just be adding the helper team to this thread so they can see it. A human will get to you soon.

!m entitytag.has_ai

Mechanism: has_ai

(Property) Controls whether this entity will use the default Minecraft AI to roam and look around.
This tends to have implications for other vanilla functionality, including gravity.
This generally shouldn't be used with NPCs. NPCs do not have vanilla AI, regardless of what this tag returns.
Other programmatic methods of blocking AI might also not be accounted for by this tag.

I see! Thanks so much! Is there a way to just freeze them in place without having to remove their ability to shoot projectiles?

[shy surge]

Could maybe give them slowness

Ah, okay. So my problem is that Withers are eating 20% of tps through aiStep and I was wondering if there's a way to mitigate it with that

[shy surge]

I don't think so

!spark

Info: spark

The "timings" system within Spigot/Paper is incredibly inaccurate for use with Citizens, and cannot be used to diagnose any issues related to Citizens. It notably blames Citizens for a significant amount of entity-related lag (that isn't in any way caused by Citizens).

For accurate timings, you need a Java profiler. There are a variety of profiler options (WarmRoast, YourKit, VisualVM, ...), but the simplest to use on a Spigot server is a plugin named "Spark" that embeds WarmRoast, which you can find here: https://www.spigotmc.org/resources/spark.57242/.

To get a spark report, type /spark profiler start, then replicate lag issues (for no more than about a minute), then /spark profiler stop, and post the link it gives you.

yup I am using Spark:

Do you guys think cancelling this will help with the lag? 🤔

Please post the full report
