Hi, my mod has an item which can be thrown to catch a mob (similar like catching a Pokémon). The mob NBT data is stored in the item stack. When using the item, an entity will be thrown which detects an impact to catch or release a mob. It worked just fine a while ago, but after upgrading to 1.10.2 there is a random bugging behaviour when I try to catch a mob. Other mobs in the world behave laggy when slapping them or when they walk for example and there is no error thrown in the console. Here is the code:

 

@Override

    protected void onImpact(RayTraceResult mop)

    {

    if(!this.worldObj.isRemote){

    if (mop.entityHit != null && entity_nbt == null && mop.entityHit instanceof EntityLivingBase){

    if(MyUtils.checkHasTag(mop.entityHit, DENY_TAG)){

                    dropEmptySoulPearl(this.posX, this.posY, this.posZ, damage);

                    if(this.getThrower() != null){

                    MyUtils.sendChatMessage(getThrower(), "This entity has a protection which makes it uncatchable");

                    }

                    this.setDead();

                    return;

            }else{

                ItemStack is = new ItemStack(MyItems.SOUL_PEARL, 1);

                is.setItemDamage(damage);

                if(mop.entityHit.hasCustomName()){

                is.setStackDisplayName(mop.entityHit.getCustomNameTag());

                }

                ItemSoulPearl.catchEntity(is, (EntityLivingBase)mop.entityHit);

                mop.entityHit.setDead();

    this.worldObj.playSound(this.posX, this.posY, this.posZ, SoundEvents.ENTITY_GENERIC_EXPLODE, SoundCategory.NEUTRAL, 4.0F, (1.0F + (this.worldObj.rand.nextFloat() - this.worldObj.rand.nextFloat()) * 0.2F) * 0.7F, true);

                this.worldObj.spawnParticle(EnumParticleTypes.EXPLOSION_NORMAL, this.posX, this.posY, this.posZ, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, new int[] {Item.getIdFromItem(MyItems.SOUL_PEARL)});

                EntityItem ei = new EntityItem(this.worldObj, mop.entityHit.posX, mop.entityHit.posY, mop.entityHit.posZ, is);

                this.worldObj.spawnEntityInWorld(ei);

                this.setDead();

                return;

            }

    }else if (entity_nbt != null){

    Entity entity = EntityList.createEntityFromNBT(entity_nbt, worldObj);

                if(entity == null){

            dropEmptySoulPearl(this.posX, this.posY, this.posZ, damage);

                this.setDead();

                return;

                }

                entity.setUniqueId(UUID.randomUUID());//if(!can_drop)

                if(custom_name != null)entity.setCustomNameTag(custom_name);

                entity.setPosition(this.posX, this.posY, this.posZ);

            this.worldObj.spawnEntityInWorld(entity);

            this.worldObj.playSound(this.posX, this.posY, this.posZ, SoundEvents.ENTITY_GENERIC_EXPLODE, SoundCategory.NEUTRAL, 4.0F, (1.0F + (this.worldObj.rand.nextFloat() - this.worldObj.rand.nextFloat()) * 0.2F) * 0.7F, true);

            this.worldObj.spawnParticle(EnumParticleTypes.EXPLOSION_NORMAL, this.posX, this.posY, this.posZ, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, ((double)this.rand.nextFloat() - 0.5D) * 0.08D, new int[] {Item.getIdFromItem(MyItems.SOUL_PEARL)});

            }

    dropEmptySoulPearl(this.posX, this.posY, this.posZ, damage + 1);

            this.setDead();

    }

    }

   

    private void dropEmptySoulPearl(double x, double y, double z, int damage){

    if(can_drop && damage < MyItems.SOUL_PEARL.getMaxDamage()){

    ItemStack is = new ItemStack(MyItems.SOUL_PEARL, 1);

        is.setItemDamage(damage);

    EntityItem ei = new EntityItem(this.worldObj, x, y, z, is);

        this.worldObj.spawnEntityInWorld(ei);

    }

    }

 

 

Btw I'm using Forge 12.18.1.2020

bump?
