I just wanna make shop system in my server, but there is no way to get EntityPlayer.getName() directly.

My design is setup command computer as main shop, and players can access shop via wireless pocket computer.

Send messages "USERNAME,seed,3" from pocket computer, then command computer receive it and exec "clear USERNAME seed 3" "wallet USERNAME add (3*price of seed)"

I know that cannot be implemented in block based computer because it can be interacted by multiple user. But pocket computer just can be interacted by just only one user at same time. So now, additional api that can access owner EntityPlayer info is needed.

Well, thx to your advise, but i need wireless modem function(rednet) and entity sensor funtion(get name) at same time and does not occupy armor slot(neural connector)...its very useful but over spec to me. If any other way to get specified player's information in that mod?

If you've got baubles installed, (it's required by Botania and Thaumcraft, so quite possibly), you can put the neural connector in a baubles slot. Otherwise, no - sorry!

plethora may be able to provide what you need

Baubles works very well! Thanks so much. The last thing to do is just scan only one entity player who equips and owns that neural connector.
