[1.18.1] NullPointerException is thrown when trying to spawn custom projectile

[Davide_24]

So I am porting code from 1.17 to 1.18 and there is a problem. When you throw / spawn the projectile entity it crashes the game. The full log can be found here: https://www.toptal.com/developers/hastebin/vifidaxibo.yaml
I do not know why this is happening.

Here is the class where I register the renderers:

@Mod.EventBusSubscriber(modid = Catty.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
public class ClientEventBusSubscriber {

    private static final Logger LOGGER = LogManager.getLogger();

    //@SubscribeEvent                OLD
    //public static void clientSetup(FMLClientSetupEvent event) {
    //    ItemRenderer renderer = Minecraft.getInstance().getItemRenderer();
    //
    //    LOGGER.info("Entity renderers registered!");
    //}

    @SubscribeEvent
    public void RegisterEntityRenderers(EntityRenderersEvent.RegisterRenderers event) {
        event.registerEntityRenderer(EntityInit.PUSHEEN_PROJECTILE.get(), ThrownItemRenderer::new);
        LOGGER.info("Catty entity renderers registered!");
    }
}

 

Here is the PusheenEntity Class: 

public class PusheenEntity extends ThrowableItemProjectile {
    public PusheenEntity(EntityType<? extends PusheenEntity> type, Level world) {
        super(type, world);
    }

    public PusheenEntity(Level world, LivingEntity entity) {
        super(EntityInit.PUSHEEN_PROJECTILE.get(), entity, world);
    }

    public PusheenEntity(Level world, double x, double y, double z) {
        super(EntityInit.PUSHEEN_PROJECTILE.get(), x, y, z, world);
    }

    @ParametersAreNonnullByDefault
    @Override
    protected void onHit(HitResult rtResult) {
        super.onHit(rtResult);
        Explosion.BlockInteraction explosion$mode = net.minecraftforge.event.ForgeEventFactory.getMobGriefingEvent(this.level, this.getOwner()) ? Explosion.BlockInteraction.DESTROY : Explosion.BlockInteraction.NONE;
        this.level.explode(this, this.getX(), this.getY(), this.getZ(), 2.0F, explosion$mode);
        if (!this.level.isClientSide) {
            this.discard();
        }
    }


    @Nonnull
    @Override
    protected Item getDefaultItem() {
        return ItemInit.PUSHEEN.get().asItem();
    }

    @Nonnull
    @Override
    public Packet<?> getAddEntityPacket() { return NetworkHooks.getEntitySpawningPacket(this); }
}

The entity is registered here:

public class EntityInit {
    public static final DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITIES, Catty.MOD_ID);

    public static final RegistryObject<EntityType<PusheenEntity>> PUSHEEN_PROJECTILE = ENTITY_TYPES.register("pusheen_projectile", () -> EntityType.Builder.<PusheenEntity>of(PusheenEntity::new, MobCategory.MISC).sized(0.25F, 0.25F).clientTrackingRange(4).updateInterval(10).build("pusheen_projectile"));
}

Any help will be appreciated

You have not registered a renderer for your entity. Your attempt at doing so does nothing, because your event handler is never called, because @EventBusSubscriber registers the Class to the event bus, but your method is not static.

Thank you so much!  Did not realize that I forgot to make the method static! Silly mistake
