I'm new to minecraft modding, after watching some tutorials, i just started to create a new mod.. I created a inventory and try to store the items in it using NBT data, but its not working,(Items in it still gone after restart the server)
cause code is quiet long, i only post the methods with NBTs
public class TileEntityProcessorHolder extends TileEntity implements IInventory{
private ItemStack[] items;
private int[] inPorts;
private int[] outPorts;

PS: i can't find game data so i can't check whether the NBT datas have been saved correctly, but as far as i use "println" in writeToNBT, it seems i do have wrote all datas
