.plr files

Is there a way (like using a mod cheat engine or something) to save a character file from in game? Because I've been playing on a server with a server sided character thing and I really love the character that I have on that server. So what I'm just trying to ask is, is there a way to make a .plr file from inside a server so I can play on that character on my own worlds...

I havn't heard about some client have that ability. It is not difficult, but useless: why don't they use some local inventory editor to create a player like that?
Internet lagging may cause server side character overwrite local player, but it is not a good solution i think.

You know you could just spawn in the items on that character for another character instead of waiting for someone to make a hack for it.
Its much more simple.

As i remember YATC 0.3v has this option. Join the server and .invsave <name> Then just go to single player and do .invload <previous name>

You could also just spawn the items in but that is much slower
