I'm trying to switch my server over to a new mod pack, while keeping player inventory and a few other aspects of playerdata. I want to be able to transfer a player from one server to another, while resetting their location data. Are there specific tools I use to view and edit these values, and which files specifically under the playerdata folder would contain them?
To clarify, When their location data is reset I would like them to go to spawn. If it wont default, then entering a value will be a little more work, but sufficient.
I've already transferred the playerdata into my new world file. I plan in switching the server every-so-often and allowing these item transfers quite abit, so I need to know for the future how to solve this without requiring all of my players to be coordinated during the transfer.
Minecraft 1.7.6 or newer (UUID)
On Minecraft 1.7.6 and above, Mojang uses a new UUID format. Use a UUID lookup tool, like http://minecraft-techworld.com/uuid-lookup-tool to determine the UUID of the player you wish to reset.
