How to keep xp on death

How can i keep a players xp and not drop xp when they die?

 

anyone wanna help or na?

 

Cancel the xp drop, and give back the amount of xp

 

how do i cancel it

 

entity spawn event, check if its an xp orb, and cancel it

 

how about giving it back to them? maybe i make a variable for their xp, set it when they die then give back when they respawn?

 

$player->addXp($player->getXpDropAmount());
