This plugin that I made a bit over a month ago, gives new players, or well, silly ones, a grace period after they join, where they won't drop their items, or xp when they die. I originally got the idea to do this, when I had players on my server dying over and over again, but I didn't want to enable keep inventory for everyone, since I felt that would make it too easy for players that are already established, and skilled at what they do.

Commands:

/kiojtoggle: Toggle the protection on or off.

/kiojreset: Reset the grace period for a player.

/kiojsettime: Set the grace period for a player.

/kiojquery: Query the time for a player.

Permission nodes:

None needed for any non-admin players, the plugin will work for them out of the box, however for commands to configure the plugin, permission nodes will be required:

kiojtoggle: kioj.toggle

kiojreset: kioj.reset

kiojsettime: kioj.settime

kiojquery: kioj.query

Config options:

Several values can be customised under KeepInventoryOnJoin/config.yml

inventoryCountdownInSeconds: How much time in seconds, do new players get for their grace period.

firstJoinSound: The sound to play when a new player joins, and their grace period starts.

Messages can also be customised under KeepInventoryOnJoin/lang.yml
