[1.10.2]How to override vanilla AI with a modified version?

[OrangeVillager61]

How to override vanilla AI with a modified version of the same AI. I'm making a small mod where it reduces the doors required for villager breeding and I made a class with a slightly edited version of the villager mate AI. However how do I override the vanilla AI?

[Animefan8888]

I see two ways of doing this

1. Create a new EntityVillager that uses your new AI and replace all vanilla villagers with it.

2. Use AccessTransformer or Reflection to change EntityLiving tasks variable to not be final.

Actually let me correct myself no need to use access transformers or even create your own entity, you may be able to use an event that gets called on entity creation or after that, and change the default mating task since you can call tasks.add(position, new EntityVillagerAI(variables));

Alright, I've got the event class, but I cannot find the tasks.add command.

my solution would to make a custom entity, the same as the villager (but with the custom ai) and whenever a villager spawns naturally (hook onto that with the event system), cancel the spawn and spawn the custom entity instead.

Have you created a EntityVillager variable if not the event should have an entity variable you can check if it is an EntityVillager, and if so...

 

@SubscribeEvent
public void entityVillagerAIOverride(EventYouAreUsingClass event) {
     if (event.entity != null && event.entity instanceof EntityVillager) {
          EntityVillager villager = (EntityVillager) event.entity;
          villager.tasks.add(number, new VillagerAI());
     }
}[

 

Also don't forget to register your event using

MinecraftForge.EVENT_BUS.register(new EventHandlerClass());

I did suggest that but if he just Overrides the Mating AI he won't have to create a new Entity, and this way it could still be compatible with other mods that extend EntityVillager assuming he chechs to see if the position he is overriding is an instance of the vanilla AI.

Yeah, but that could easily break or make useless other mods that affect the villager.

Okay I used the wrong event apparently, what do I use for EventYouAreUsingClass? LivingSpawnEvent?

[Animefan8888]

LivingSpawnEvent should work, what were you using?

I was using EntityJoinWorld event and then I saw LivingSpawnEvent so I got confused.

[OrangeVillager61]

Alright I got it to work . But one last question: is the AI handled completely server side?

[Animefan8888]

I believe so, considering almost if not everything except rendering is handled server side.
