I am trying to remove the AvoidEntity goals for a creeper to make it not run away from ocelots. This is my code:

 

@Mod.EventBusSubscriber(modid = CreeperMod.MODID)
public class EntityChangeEvent {

    @SubscribeEvent
    public static void onSpawn(EntityJoinWorldEvent event) {
        if (event.getEntity() instanceof CreeperEntity) changeAI((CreeperEntity) event.getEntity(), event);
    }
	
	private static void changeAI(CreeperEntity entity) {
        if (entity.world != null && !entity.world.isRemote) {
            CreeperMod.LOGGER.info(entity.goalSelector.getRunningGoals().count());
            entity.goalSelector.getRunningGoals().forEach((action) -> {
                CreeperMod.LOGGER.info(action.getGoal());
                if (action.getGoal() instanceof AvoidEntityGoal) {
                    entity.goalSelector.removeGoal(action.getGoal());
                    CreeperMod.LOGGER.info("removed");
                }
            });
        }
    }

But it looks like the AvoidEntity goals are not running when the creeper is spawned. How would I remove those goals. Thanks

This doesn't even compile.

The goal is only running when there is an OcelotEntity or a CatEntity nearby. You have to use Reflection to get the Goal out of the GoalSelector.

Ok, thanks.

This is my code so far but it doesn't seem to work

private static void changeAI(CreeperEntity entity) {
        if (entity.world != null && !entity.world.isRemote) {
            Set<PrioritizedGoal> goals = ObfuscationReflectionHelper.getPrivateValue(GoalSelector.class, entity.goalSelector, "goals");
            ChangeMod.LOGGER.info(goals);
            for (PrioritizedGoal goal: goals) {
                if (goal.getGoal() instanceof AvoidEntityGoal) {
                    entity.goalSelector.removeGoal(goal);
                    ChangeMod.LOGGER.info(goal.getGoal().toString());
                }
            }
            goals = ObfuscationReflectionHelper.getPrivateValue(GoalSelector.class, entity.goalSelector, "goals");
            ChangeMod.LOGGER.info(goals);
        }
    }

But the creepers still avoid them and the goals are the same length

It should be goal.getGoal()

 

Also you cannot iterate and remove an entry. You will get a ConcurrentModificationException. Use an iterator.
