[1.7.10] How to sync items added to inventory?


Recommended Posts

I am currently trying to write a mod that sets items to specific player inventory slots (like armor) without using any containers or similar. I got that working so far using player.inventory.setInventorySlotContents(...), however the items are only visible after relogging, which tells me that I am missing something to synchronize that change to the player.

 

How do I properly synchronize a batch change to the player's inventory?

The code that adds the items. Log output tells me that all items are properly added on the server:

 

public void giveItemsToPlayer(final EntityPlayer player) {
    int count = GravesAssets.itemsPerSecond >= 0 ? GravesAssets.itemsPerSecond / TICKS_PER_SECOND : Integer.MAX_VALUE;
    FMLLog.info("Giving %d of %d items back to %s...", count, this.inventoryContent.size(), player.getDisplayName());
    if (count == 0) {
      return;
    }
    InventoryContent content;
    final Deque<InventoryContent> notAdded = new LinkedList<InventoryContent>();

    while ((count-- > 0) && ((content = this.inventoryContent.poll()) != null)) {
      FMLLog.info("Returning %s...", content.toString());
      try {
        switch (content.inventoryID) {
          case INVENTORY_ID_VANILLA:
            if (player.inventory.getStackInSlot(content.slot) == null) {
              player.inventory.setInventorySlotContents(content.slot, content.itemStack);
            } else {
              notAdded.add(content);
              FMLLog.info("Failed.");
            }
            break;
        }
      } catch (Exception e) {
        FMLLog.warning("Failed to add item to inventory: %s\n%s", e.toString(), content.toString());
      }
    }

    for (InventoryContent item : notAdded) {
      FMLLog.info("Adding %s...", item.toString());
      if (player.inventory.addItemStackToInventory(item.itemStack) == false) {
        this.inventoryContent.add(item);
        FMLLog.info("Failed");
      }
    }

    if (this.inventoryContent.isEmpty()) {
      FMLLog.info("All items have been returned");
      this.worldObj.setBlockToAir(this.xCoord, this.yCoord, this.zCoord);
    } else {
      FMLLog.info("Items remain in grave");
      this.markDirty();
    }
  }

 

Neither setInventorySlotContents nor addItemStackToInventory synchronize to the client.

From the corresponding block to the tile entity code above:

 

@Override
  public boolean onBlockActivated(final World world, final int x, final int y, final int z, final EntityPlayer player, final int side, final float hitX, final float hitY, final float hitZ) {
    if (world.isRemote == false) {
      final TileEntity tileEntity = world.getTileEntity(x, y, z);
      if (tileEntityClass.isInstance(tileEntity)) {
        tileEntityClass.cast(tileEntity).giveItemsToPlayer(player);
      } else {
        FMLLog.severe("Grave TileEntity expected %s, but found %s", tileEntityClass.getName(), tileEntity == null ? "null" : tileEntity.getClass().getName());
      }
    }
    return true;
  }

I managed to find your topic: http://www.minecraftforge.net/forum/index.php/topic,20135.0.html

 

After some more fiddling with the way Minecraft handles worlds, I realized that the TileEntity (probably) needs to be requested as follows:

 

- On the server: DimensionManager.getWorld(message.dimensionID)

- On the client: Minecraft.getMinecraft().theWorld  (not sure about this one)

 

The client often re-creates the world around the player, i.E. if he dies, which will cause the tile entity to be re-created as well, which however - to complicate things further - is NOT the tile that is actually used in the world.

 

Also it is unclear to me what happens if the player is in a different dimension (there is only one theWorld) and the server sends an update for that tile entity, which makes me speculate that there is a better way to do this.

 

I'd love to get some more feedback on this if you have the time.

For syncing the server player inventory with the client, just use the player container for that:

player.inventoryContainer.detectAndSendChanges();

 

No need for custom packets!

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

    • I'm reworking vanilla enchanting mechanics for my mod, and need to completely replace the functionality of vanilla enchanting tables and anvils. I have 2 new tile entity blocks set up, and I'm working on their functionality at the moment. When they're done, how would I replace the vanilla blocks with them? Alternatively, how would I replace the tile entity of the vanilla blocks with my own tile entities?
