[1.16.4] mob Tracking/Attacking player

[<Gl33p_0r4nge>]

Hi

maybe Im super dumb but I just cant find where to change/cancel what entity should be the mob attacking (I mean the thing when for example zombie follows you and attacks you) can someone tell me where can I find this and how to change the value to null or cancel the tracking?

 

I just want to make mob neutral when Im wearing my custom mod armor.

 

Thanks for any help.

OMG it works but not completly. It will probably be something with my code bcs I have never used predicates or reflections but I somehow managed to make it work (and Im proud of it 😆). So now I have problem with that when it is not "angry" on me and I have the armor its okay he don't even notice me but while he is targeting me and I equip the armor he is still following me and is trying to hit me.

 

Here is the code:

@SubscribeEvent
    public static void onEntityJoin(EntityJoinWorldEvent event){
        if (event.getEntity().isLiving()) {
            LivingEntity living = (LivingEntity) event.getEntity();
            if (living.isEntityUndead()) {
                MonsterEntity monster = (MonsterEntity) event.getEntity();
                Field goalsField = null;
                try {
                    goalsField = monster.targetSelector.getClass().getDeclaredField("goals");
                    goalsField.setAccessible(true);
                    Set<PrioritizedGoal> goals = (Set<PrioritizedGoal>) goalsField.get(monster.targetSelector);
                    for (PrioritizedGoal g : goals) {
                        if (g.getGoal() instanceof NearestAttackableTargetGoal<?>){
                            NearestAttackableTargetGoal<?> goal = (NearestAttackableTargetGoal<?>) g.getGoal();
                            Field targetClassField = goal.getClass().getDeclaredField("targetClass");
                            targetClassField.setAccessible(true);
                            Class<?> targetClass = (Class<?>) targetClassField.get(goal);
                            if (targetClass == PlayerEntity.class || targetClass == ServerPlayerEntity.class) {
                                Field targetESField = goal.getClass().getDeclaredField("targetEntitySelector");
                                targetESField.setAccessible(true);
                                EntityPredicate targetEntitySelector = (EntityPredicate) targetESField.get(goal);

                                targetEntitySelector.setCustomPredicate((target) -> {
                                    for (ItemStack itemStack : target.getArmorInventoryList()) {
                                        if (ItemTags.getCollection().getTagByID(
                                                new ResourceLocation("oreganized:silver_tinted_items"))
                                                .contains(itemStack.getItem())) return false;
                                    }
                                    return true;
                                });
                            }
                        }
                    }
                } catch (NoSuchFieldException | IllegalAccessException noSuchFieldException) {
                    noSuchFieldException.printStackTrace();
                }
            }
        }
    }

 

thanks for help!

Okay I know that what I did is horible but I look at it and rework it so now Im using the ObfuscationReflectionHelper and it works fine.

But for the static final, I need to call it only once each time enitity spawns (or the world loads) so I think its not neccessary.
