Change entity's AI goals dynamically

[FantaLaTone]

Hello

I have a mob with simple AI goals. I want to change mob's behaviour depend on users commands. How I can do that?

Just register a game rule and reference it in your AI.

The game rule will handle saving it per world correctly and the command/permissions to change it.

I used a cheaper version. I am just removing all goals and adding goals I wanted later. Is this can be a problem?

Minecraft does that when you for example setTame() on a Cat.

 

If you look at Zombies smashing turtle eggs. This just checks the mob griefing rule inside the goal itself.

 

There's also a notion of "control flags" where you can enable/disable flags in the goal selector and match those against flags in the goal to see which can run.

Never played with that, and it doesn't look widely used in vanilla?

 

My question to you is how are you saving the config changed by the command? See the discussion on the other thread.
