[1.16.1] Custom Projectile not working (creating an EntityType)

[majesity]

Hi all, for my mod I am making a spider that shoots poisonous projectiles at the player (called a crawler) and I want to make a custom projectile for this. I have made the projectile entity class and I know that I need to make the rendering class, but before I do that I need to make a custom EntityType in order to even create the projectile entity in the world. Here is my projectile class:

public class CrawlerVenomEntity extends AbstractCrawlerVenomEntity {
    public int explosionPower = 0;
    public double explosionRadius = 2.0;

    public CrawlerVenomEntity(EntityType<CrawlerVenomEntity> type, World worldIn) {
        super(type, worldIn);
    }

    @OnlyIn(Dist.CLIENT)
    public CrawlerVenomEntity(EntityType<? extends CrawlerVenomEntity> type, World worldIn, double x, double y, double z, double accelX, double accelY, double accelZ) {
        super(type, x, y, z, accelX, accelY, accelZ, worldIn);
        this.setVelocity(accelX, accelY, accelZ);
    }

    /**
     * Called when this EntityFireball hits a block or entity.
     */
    protected void onImpact(RayTraceResult result) {
        super.onImpact(result);
        if (!this.world.isRemote) {
            boolean flag = net.minecraftforge.event.ForgeEventFactory.getMobGriefingEvent(this.world, this.func_234616_v_());
            this.world.playSound(this.getPosX(),this.getPosY(),this.getPosZ(), SoundEvents.ENTITY_SPIDER_AMBIENT, SoundCategory.HOSTILE,1.0F,1.0F,true);
            World world = this.getEntityWorld();
            world.addParticle(ParticleTypes.ITEM_SLIME,this.getPosX(),this.getPosY()+0.5,this.getPosZ(),0,1,0);
            world.addParticle(ParticleTypes.ITEM_SLIME,this.getPosX(),this.getPosY()+1.5,this.getPosZ(),0,1,0);
            world.addParticle(ParticleTypes.ITEM_SLIME,this.getPosX(),this.getPosY()+1.0,this.getPosZ(),0,1,0);

            // this.world.createExplosion((Entity)null, this.getPosX(), this.getPosY(), this.getPosZ(), (float)this.explosionPower, flag, flag ? Explosion.Mode.DESTROY : Explosion.Mode.NONE);
            Vector3d victor = result.getHitVec();
            AxisAlignedBB aabb = new AxisAlignedBB(this.getPosX()-explosionRadius,this.getPosY()-explosionRadius,this.getPosZ()-explosionRadius,
                    this.getPosX()+explosionRadius,this.getPosY()+explosionRadius,this.getPosZ()+explosionRadius);
            for(LivingEntity e:this.world.getEntitiesWithinAABB(LivingEntity.class,aabb)) {
                e.attackEntityFrom(DamageSource.MAGIC,5);
                e.addPotionEffect(new EffectInstance(Effects.POISON,80,1));
            }
            this.remove();
        }

    }

    /**
     * Called when the arrow hits an entity
     */
    protected void onEntityHit(EntityRayTraceResult p_213868_1_) {
        super.onEntityHit(p_213868_1_);
        if (!this.world.isRemote) {
            Entity entity = p_213868_1_.getEntity();
            Entity entity1 = this.func_234616_v_();
            entity.attackEntityFrom(DamageSource.MAGIC, 6.0F);
            if (entity1 instanceof LivingEntity) {
                this.applyEnchantments((LivingEntity)entity1, entity);
            }

        }
    }

    public void writeAdditional(CompoundNBT compound) {
        super.writeAdditional(compound);
        compound.putInt("ExplosionPower", this.explosionPower);
    }

    /**
     * (abstract) Protected helper method to read subclass entity data from NBT.
     */
    public void readAdditional(CompoundNBT compound) {
        super.readAdditional(compound);
        if (compound.contains("ExplosionPower", 99)) {
            this.explosionPower = compound.getInt("ExplosionPower");
        }

    }

    protected ItemStack getStack() {
        return new ItemStack(Items.SLIME_BALL);
    }

    @OnlyIn(Dist.CLIENT)
    public ItemStack getItem() {
        ItemStack itemstack = this.getStack();
        return itemstack.isEmpty() ? new ItemStack(Items.SLIME_BALL) : itemstack;
    }

}

Here is the AbstractCrawlerVenomEntity class:

@OnlyIn(
        value = Dist.CLIENT,
        _interface = IRendersAsItem.class
)
public abstract class AbstractCrawlerVenomEntity extends DamagingProjectileEntity implements IRendersAsItem {
    private static final DataParameter<ItemStack> STACK = EntityDataManager.createKey(net.minecraft.entity.projectile.AbstractFireballEntity.class, DataSerializers.ITEMSTACK);

    public AbstractCrawlerVenomEntity(EntityType<? extends AbstractCrawlerVenomEntity> p_i50166_1_, World p_i50166_2_) {
        super(p_i50166_1_, p_i50166_2_);
    }

    public AbstractCrawlerVenomEntity(EntityType<? extends AbstractCrawlerVenomEntity> p_i50167_1_, double p_i50167_2_, double p_i50167_4_, double p_i50167_6_, double p_i50167_8_, double p_i50167_10_, double p_i50167_12_, World p_i50167_14_) {
        super(p_i50167_1_, p_i50167_2_, p_i50167_4_, p_i50167_6_, p_i50167_8_, p_i50167_10_, p_i50167_12_, p_i50167_14_);
    }

    public void setStack(ItemStack p_213898_1_) {
        if (p_213898_1_.getItem() != Items.FIRE_CHARGE || p_213898_1_.hasTag()) {
            this.getDataManager().set(STACK, Util.make(p_213898_1_.copy(), (p_213897_0_) -> {
                p_213897_0_.setCount(1);
            }));
        }

    }

    protected ItemStack getStack() {
        return this.getDataManager().get(STACK);
    }

    @OnlyIn(Dist.CLIENT)
    public ItemStack getItem() {
        ItemStack itemstack = this.getStack();
        return itemstack.isEmpty() ? new ItemStack(Items.FIRE_CHARGE) : itemstack;
    }

    protected void registerData() {
        this.getDataManager().register(STACK, ItemStack.EMPTY);
    }

    public void writeAdditional(CompoundNBT compound) {
        super.writeAdditional(compound);
        ItemStack itemstack = this.getStack();
        if (!itemstack.isEmpty()) {
            compound.put("Item", itemstack.write(new CompoundNBT()));
        }

    }

    /**
     * (abstract) Protected helper method to read subclass entity data from NBT.
     */
    public void readAdditional(CompoundNBT compound) {
        super.readAdditional(compound);
        ItemStack itemstack = ItemStack.read(compound.getCompound("Item"));
        this.setStack(itemstack);
    }
}

And I am trying to create an EntityType for this class so I can spawn it in by doing the following in my EntityTypesInit:

public class ModEntityTypes {

    public static DeferredRegister<EntityType<?>> ENTITY_TYPES = DeferredRegister.create(ForgeRegistries.ENTITIES, MajCraft.MOD_ID);

    // All my other Entity Types here

    // Projectile Entity Types
      public static final RegistryObject<EntityType<CrawlerVenomEntity>> CRAWLER_VENOM = ENTITY_TYPES.register("crawler_venom",
            () -> EntityType.Builder.create(CrawlerVenomEntity::new, EntityClassification.MISC)
                    .size(1.0f,0.5f)
                    .build(new ResourceLocation(MajCraft.MOD_ID, "crawler_venom").toString())
    );

}

But for some reason it does not like the CrawlerVenomEntity::new and I do not know why... I've played around with changing the data types of the parameters.

To spawn in the entity I want to do something like this: 

CrawlerVenomEntity test = new CrawlerVenomEntity(ModEntityTypes.CRAWLER_VENOM,worldIn,playerIn.getPosX()+playerIn.getForward().getX(),playerIn.getPosY()+1.25,playerIn.getPosZ()+playerIn.getForward().getZ(),playerIn.getForward().getX(),playerIn.getForward().getY(),playerIn.getForward().getZ())

 

Why isn't this working? Thank you for your time!

                    .size(1.0f,0.5f)
                    .build(new ResourceLocation(MajCraft.MOD_ID, "crawler_venom").toString())
