Save data on death

[Babatunde]

Hi Modders, 

 

I'm working on a mod where a player starts with 1 heart and every time they die they gain a heart until they have 10 hearts.

 

But I struggling with how I save the amount a hearts the player has. If I put it in the player data, it will be deleted when the player dies. Same goes for capabilities.

I've tried it with a Hashmap but I know its not the best way of doing thing so I'd like some feedback from you guys. 

 

Thanks.

 

EDIT: I'm using 1.15.2 and 1.14.4.
