[SOLVED][1.12.2] Access to another player's inventory through dimensions

[Sunser 3]

I'm trying to implement the well-known /invsee command. This is what I have done so far:

    @Override
    public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException {
        if (args.length != 1) {
            throw new InvalidNumberOfArgumentsException();
        }
        // fetch target's inventory
        EntityPlayerMP target = server.getPlayerList().getPlayerByUsername(args[0]);
        if (target == null) return; // TODO: send an error message
        IInventory targetInventory = target.inventory;
        // displaying it to sender
        EntityPlayerMP player = (EntityPlayerMP)sender;
        player.displayGUIChest(targetInventory);
    }

 

It works perfectly when both sender and target are in the same dimension, but if they are not, the GUI closes instantly. So I took a look at the

net.minecraft.entity.player.EntityPlayerMP#displayGUIChest

source code and tried to understand why.

 

This is the piece of code which I think blocks me: (l.948)

      if (this.openContainer != this.inventoryContainer)
            {
                this.closeScreen();
            }

 

I also took a look at

net.minecraft.entity.player.EntityPlayerMP#changeDimension

to check if EntityPlayerMP's attributes openContainer and inventoryContainer where changed but it is not the case.

 

What is wrong with what I am doing ? I feel like I missed something!

It has nothing to do with dimension. InventoryPlayer#isUsableByPlayer requires the using player to be within 8 blocks of the target player.

You need to create your own inventory wrapper which does not have this limitation.

Ouch, I totally missed it. Thank you !
