How do you ensure that you keep the items after death in Survival?

In the Java version of Minecraft

/ gamerule keepInventory true

But that is in the creativ or in the survival with cheats. As I see it, he probably has no cheats "

Then he has to activate cheats otherwise that will not be

And what exactly do you see that?

Usually with / gamerule keepinventory true but if you do not have cheats it will not work. If you want to keep your world i recommend you to esc and then open in lan but then open with cheats in lan. Then you can enter the command and run and then rejoinst are the "command rights" away.

Survival is by default without cheats

I wrote up like that is hopefully understandable

Thanks, that's good, because I build a server anyway

Ok ^^ I would simply recommend you in the konsole / op your name
