Here's the error

And the code on the lines:

Line 26 of StatsData : plugin.getConfig().set("Stats." + k.getName() + ".Kills", kills + 1);


Line 37 of suicide class: p.setHealth(0);

 

@Fhbgsdhkfbl
"plugin" is probably null. Have a look here.
"k" could also be null and "kills" also (if it is an Integer and not an int. Which it shouldn't be anyways).

There is also a NPE here:
"at me.Fhbgsdhkfbl.SB.updateSB(SB.java:64) ~[?:?]"

 

@I Al Istannen
int kills = plugin.getConfig().getInt("Stats." + p.getName() + ".Kills");

Line 64

 

@Fhbgsdhkfbl check the kills if null

Code:

if(kills == null) {
  // do something
}

or make it better

at PlayerJoinEvent

// do this to keep the player's kill not null

Code:

plugin.getConfig().set("Stats." + e.getPlayer().getName() + ".Kills", 0);

 

@Fhbgsdhkfbl
Then plugin is probably null. Maybe the same mistake as in the other NPE, in the class StatsData. It is the same structure there.
