Mob AI!

[wyler0]

Hey Guys,

I am new here and I will begin my rampage of posts to follow this one with a question:

 

  Reveal hidden contents

Are their any places to learn mob AI or could one of you help me?

 

 

My Problem:

 

  Reveal hidden contents

I need to make a mob AI that, when called, will automatically find and follow the nearest mob. The AI Will always be being called (So no wandering AI) I have tried using a clone of the code that makes wolves attack sheep and pass it EntityLiving.class but this does not work. After further testing I have noticed that my script works... but only for Players. So any help would be greatly appreciated!

PS: I am just learning and I am not to bad (in-between moderate and advanced) and am still learning Mob AI to, in the future, create a robot making mod!

What is your code? where are you declaring your AI class?

Then remove the player references in your code.

 

As for AI, there is no place to learn that.

You can read the AI classes from Minecraft, but an AI is mostly your own code anyway.

You don't have to follow the vanilla AI system either.

Looks okay, but where do you add this custom AI to mobs?

 

Entity AI 'tasks' and 'targetTasks' are both public fields, so you can add new AI through the use of Events such as EntityConstructingEvent or EntityJoinWorldEvent.
