December 12, 20213 yr the best way would be to replace the target Goals of the Mobs in EntityJoinWorldEvent, with your own TargetGoals

December 12, 20213 yr you need to extends the vanilla Goals, overwrite the tick method and call super if you want to run the vanilla logic

December 16, 20213 yr Author 15 hours ago, Luis_ST said: sorry was 1.18 class name, in 1.16.5 it's LookAtGoal What I do now is to extend LootAtGoal, then add my custom LootAtGoal to the monster, and then override the tick method, but the parent method is still called. So i don't understand, what to do I'm using translation, if you understand, I'm sorry my custom LookAtGoal class: public class MonsterLookAtGoal extends LookAtGoal { public MonsterLookAtGoal(MobEntity entity, Class<? extends LivingEntity> livingEntity, float lookDistance) { super(entity, livingEntity, lookDistance); } @Override public void tick() { } } caller: @SubscribeEvent public static void onEntityJoinWorldEvent(final EntityJoinWorldEvent event) { Entity entity = event.getEntity(); if (entity.isAlive() && entity instanceof MobEntity) { MobEntity mobEntity = (MobEntity) entity; GoalSelector targetSelector = mobEntity.targetSelector; targetSelector.addGoal(1, new MonsterAttackGoal(mobEntity, false)); targetSelector.addGoal(1, new MonsterLookAtGoal(mobEntity, PlayerEntity.class, 8F)); } }

December 17, 20213 yr Author 28 minutes ago, Luis_ST said: Did you remove the existing Goal? this ? this.goalSelector.addGoal(8, new LookAtGoal(this, PlayerEntity.class, 8.0F)); How can I delete it? I have tried a lot, but there is no way to delete it. I use the removeGoal method This is the source code of removeGoal. When EntityJoinWorldEvent is called, isRunning is false, so I don’t understand how to use it now public void removeGoal(Goal p_85156_1_) { this.availableGoals.stream().filter((p_220882_1_) -> { return p_220882_1_.getGoal() == p_85156_1_; }).filter(PrioritizedGoal::isRunning).forEach(PrioritizedGoal::stop); this.availableGoals.removeIf((p_220884_1_) -> { return p_220884_1_.getGoal() == p_85156_1_; }); } I use it like this: targetSelector.removeGoal(new LookAtGoal(mob, PlayerEntity.class, 8.0F)); Edited December 17, 20213 yr by Spring
