[SOLVED][1.7.10]Ghost items drop

megabitus · August 20, 2014

Hi! I have a block that when I close the GUI I drop the items that are in slots, they drop but they leave ghost blocks, here is the code:

@Override
public void onContainerClosed(EntityPlayer entityplayer)
{
super.onContainerClosed(entityplayer);
for(int i = 0; i < TileEntityInterChest.INVENTORY_SIZE; i++)
{
ItemStack itemstack = craftMatrix.getStackInSlot(i);
if(itemstack != null)
{
entityplayer.entityDropItem(itemstack, 0.05F);
}
}
}

Can someone help me?

You should only spawn items on the server.

I've tried to do like this

@Override
    public void onContainerClosed(EntityPlayer entityplayer)
    {
            super.onContainerClosed(entityplayer);
            for(int i = 0; i < TileEntityInterChest.INVENTORY_SIZE; i++)
            {
                ItemStack itemstack = craftMatrix.getStackInSlot(i);
                if(itemstack != null && worldObj.isRemote)
                {
                    entityplayer.entityDropItem(itemstack, 0.05F);
                }
            }
    }

But it crashes now:
