Mobs Run Away

create a procedure like this:

save and build it. my procedure is named Bbb, whatever your procedure name is, remember it.

next, create another procedure like this:

in the custom code snippet box, put this piece of code in:

((MobEntity)entity).goalSelector.addGoal(1, new AvoidEntityGoal((CreatureEntity)entity, PlayerEntity.class, 10f, 1, 1.2) {
    @Override
    public boolean shouldExecute() {
        return super.shouldExecute() && BbbProcedure.executeProcedure(ImmutableMap.of("entity", this.avoidTarget, "world", this.avoidTarget.world));
    }
});

replace the BbbProcedure with the name of your procedure, for example, if the procedure is named CheckHelmet, then its CheckHelmetProcedure. also, very important, remove all the spaces in the code snippet.

save and build it. if you wear a diamond helmet, monsters should now avoid you.

thats too bad. it works fine when i tested it.

maybe you should ask for help on the parts that are confusing you

when you say remove all spaces you mean all the spaces outside the parentheses right?

or i guess i should say what spaces exactly do we delete

He means with "removing the spaces" that the Code Snippet should be in one line.

@ahznb it gives an error
