How to make an entity avoid another entity ?

[Vat1n]

Hello,

In Minecraft, we know that some entities try to avoid others like the villagers who fear the zombies or the creepers who fear the cats.
I discovered this mecanic in the registerGoals method. For example :

##From the registerGoals() method from Creeper.java

this.goalSelector.addGoal(3, new AvoidEntityGoal<>(this, Ocelot.class, 6.0F, 1.0D, 1.2D));
this.goalSelector.addGoal(3, new AvoidEntityGoal<>(this, Cat.class, 6.0F, 1.0D, 1.2D));

However, I want to make the creeper to be scared of another entity I've created (called Cubos). I don't know how should I implement another goal in the registerGoals().

Is it useful to use the Access Transformers ?

Can't you just replace it with your entities name like:

this.goalSelector.addGoal(3, new AvoidEntityGoal<>(this, CubosEntity.class, 6.0F, 1.0D, 1.2D));
//note that you should check if you really named the Entity CubosEntity!

You can, but you will need a mixin to insert that line of code into the registerGoals() method of the Creeper class. Or something along those lines.

do not change creeper class. you need to change creeper entities at runtime.

respond to "entity joins level" event. if the entity is a creeper, add your cat or whatever it is into goals of the creeper instance.
