Hello. I'm making a vehicle entity. The class is barebones but I can't get the interact() to work properly. I have a simple print line but it's not being called.

 

Entity class:

Spoiler

// package & imports

@ParametersAreNonnullByDefault
public class CaveSuitEntity extends Entity
{
    public CaveSuitEntity(EntityType<CaveSuitEntity> type, Level level)
    {
        super(type, level);
        blocksBuilding = true;
    }

    @Override
    public boolean canBeCollidedWith()
    {
        return true;
    }

    @Override
    public boolean isPushable()
    {
        return !isVehicle();
    }

    @Override
    public @NotNull InteractionResult interact(Player player, InteractionHand hand)
    {
        System.out.println("Interact test");

        return InteractionResult.PASS;
    }

    @Override
    public @Nullable Entity getControllingPassenger()
    {
        return getFirstPassenger();
    }

    @Override
    protected void defineSynchedData()
    {
    }

    @Override
    protected void readAdditionalSaveData(CompoundTag tag)
    {
    }

    @Override
    protected void addAdditionalSaveData(CompoundTag tag)
    {
    }

    public @NotNull Packet<?> getAddEntityPacket()
    {
        return new ClientboundAddEntityPacket(this);
    }
}

 

 

And the registration if it helps:

Spoiler

// Package & imports

public class LimaTechEntities
{
    private static final DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITY_TYPES, LimaTech.MODID);

    public static void init(IEventBus bus)
    {
        ENTITY_TYPES.register(bus);
    }

    public static List<EntityType<?>> getAllEntityTypes()
    {
        return ENTITY_TYPES.getEntries().stream().map(RegistryObject::get).collect(Collectors.toList());
    }

    public static final RegistryObject<EntityType<CaveSuitEntity>> cave_suit = ENTITY_TYPES.register(LimaTechIds.CAVE_SUIT,
            () -> EntityType.Builder.of(CaveSuitEntity::new, MobCategory.MISC)
                    .sized(1.25f, 2.625f)
                    .clientTrackingRange(10)
                    .fireImmune()
                    .build(LimaTechIds.CAVE_SUIT));

    public static final RegistryObject<EntityType<OrbMineEntity>> orb_mine = ENTITY_TYPES.register(LimaTechIds.ORB_MINE,
            () -> EntityType.Builder.of(OrbMineEntity::new, MobCategory.MISC)
                    .sized(0.4f, 0.4f)
                    .clientTrackingRange(10)
                    .updateInterval(20)
                    .fireImmune()
                    .noSummon()
                    .build(LimaTechIds.ORB_MINE));
}

 

 

Entity.isPickable() - controls whether the ray trace hits your entity - see GameRenderer.pick()

It is false by default, i.e. it is opt in

You can see which entity is "picked" if you press F3 to show the debug screen.

 

Unless you know what you are doing, I suggest you start with the Boat or Minecart as a reference.

Doing it from scratch and getting it right will be difficult with all the ad hoc policy methods an entity has.
