[1.16.4] Custom ProjectileEntity


Recommended Posts

Hello. Before explanation want to notice that my Eng is not good enough, sorry if I misspelled something.

So, my main problem is that I can't set entity motion similar to snowball/enderpearl/etc. In a general I'm trying to catch that minimal amount of code, which I need to create a basic projectile entity. So, now I have this:

public class SupernovaBowItem extends ItemBase {
    public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) {
        SupernovaBurstEntity burst = new SupernovaBurstEntity(worldIn, playerIn);
        burst.func_234612_a_(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 1.5F, 1.0F);
        return super.onItemRightClick(worldIn, playerIn, handIn);

Here is just a basic item, which creates a simple entity and applies motion (via func_234612_a_()) based on player current pitch and yaw. Also tried with shoot() method, which already used by a mentioned earlier - same result.

Here is my entity:

public class SupernovaBurstEntity extends ProjectileItemEntity {
    public SupernovaBurstEntity(EntityType<? extends SupernovaBurstEntity> type, World worldIn) {
        super(type, worldIn);

    public SupernovaBurstEntity(World worldIn, LivingEntity throwerIn) {
        super(EntityRegistry.SUPERNOVA_BURST.get(), throwerIn, worldIn);

    public SupernovaBurstEntity(World worldIn, double x, double y, double z) {
        super(EntityRegistry.SUPERNOVA_BURST.get(), x, y, z, worldIn);

    public void tick() {
        if (this.ticksExisted % 200 == 0) this.remove();
        SoulSparkData soulSparkData = new SoulSparkData(
                new Color(0.4F, 0.05F, 0.7F), 0.4, 80, 0.95F, false);
                getPosX(), getPosY(), getPosZ(),
                0F, 0F, 0F);

    protected void onImpact(RayTraceResult result) {

    protected Item getDefaultItem() {
        return ItemRegistry.SUPERNOVA_BOW.get();

    public IPacket<?> createSpawnPacket() {
        return NetworkHooks.getEntitySpawningPacket(this);

I don't rly need to use ProjectileItemEntity here, and I already make regular ProjectileEntity public (it's private by default for unknown reason), but just for example (compared to vanilla snowball/enderpearl/etc) I tried to do it via ProjectileItemEntity (also tried with ThrowableEntity, which is superclass for ProjectilItemEntity). What I get in result: My entity doesn't have any motion at all, it just spawns and floating in air like this:

Also noticed that I can't apply any motion to an entity at all and can move it only via move() method, but this thing makes all my previous code useless and with it I should make own implementation of movement, which is not a good thing.
As a result I want to make something like an arrow that doesn't have any gravity and just moves towards one direction.
