I have played a lot of servers in PC, and I found that there are one of the plugin that is famous is the Inventory Save. And I moved to MCPE servers, but the most annoying thing is when I die, I lose all my stuffs that I have worked hard to get them. Maybe some of the players will agree that we need a plugin that we can't lose stuffs when we die. So could you make a plugin like Inventory Save? I'm very pleased to hear from you.
this plugin will solve your problem: http://forums.pocketmine.net/plugins/respawnwithoutdroping.349/ enjoy!
