Giving someone a certain amount of exp?

I'm currently trying to give someone a certain amount of exp when they kill someone, but I'm not sure how this works. I'm not trying to set their level, but trying to give them exp. Does it have anything to do with e.getEntity().getPlayer().getKiller().getExp()...?

Wizehh
This is my current code:

Code:java

 
e.getEntity().getPlayer().getKiller().setExp(e.getEntity().getPlayer().getKiller().getExp() + 2);
 

I'm trying to make it so that each kill, the player will get 2 exp orbs automatically added to their exp bar, but when I do this, it glitches the exp bar out, and when I give myself 0 exp, it seems that the 2 exp given is actually 2 levels given.

Does anybody know how to fix?

I still need help if anybody can help me.

Trying setting exp to be equal to a variable and after every kill set that variable to exp+2

 

CandyCranium

Code:java

public void setExp(Player player, int exp) {
 
    player.setTotalExperience(0);
 
    player.giveExp(exp);
}
 
public void giveExp(Player player, int exp) {
 
    player.giveExp(exp);
}
 
@EventHandler
public void onEntityDeath(EntityDeathEvent event) {
 
    Player player;
 
    if(event.getEntity() instanceof Player) {
 
        player = (Player) event.getEntity();
 
        giveExp(player.getKiller(), expToGive);
        // expToGive = whatever value you want
    }
}

 

CandyCranium Player#setExp() takes a float between 0 and 1, representing the percentage filled the exp bar is. Player#setLevel() takes an int, and changes the green exp number, not affecting the bar at all. They're completely different things; the game just handles what to set them to when you pick up an exp orb. If you want to give players an exp orb when they kill someone, just spawn the entity at their feet instead of manually increasing their exp level.

 

Found out how:

Code:java

 
e.getEntity().getPlayer().getKiller().giveExp((int) 1.0);
 

Thanks for everybody who helped!
