getConfig().getInt() doesnt work?

Hello Guys!
I make a plugin for my own server and yesterday I started to try out the Config-System with getConfig()....
My problem is, that I can write in the Config.yml but I cant read the integers when I use them later.
For example I wanted to set the Integer -1 on player death, but it doesnt work.

Code:java

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent event) {
        if(event.getEntity() instanceof Player){
            Player p = event.getEntity().getPlayer();
            this.getConfig().set("Config.players.playerlifes."+p.getName(), this.getConfig().getInt("Config.players.playerlifes."+p.getName()) - 1); // DOESNT WORK!
            saveConfig();
 
        }
    }
 

Set integers works:

Code:java

if(command.getName().equalsIgnoreCase("something")){ //command for ops
                if(p != null){
                    if(p.isOp()){
                        getConfig().set("Config.players.playerlifes."+p.getName(), 3); // 3 lifes
                        getConfig().set("Config.players.playerteam."+p.getName(), 0); //set the team
                        p.setDisplayName("Frozenplayer");
                        p.sendMessage("Finished");
                    }
                }
                }
 
 
        }

What am I doing wrong?
Thank you for a reply.

 

Try getting the value you first, doing the subtraction, then setting the value.

 

Didnt work, but thanks
Maybe its something with the getEntity?

 

I guess I can help myself now:

Code:java

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent event) {
        if(event.getEntity() instanceof Player){
            reloadConfig();
            Player p = event.getEntity().getPlayer();
            int playerlife = getConfig().getInt("Config.players.playerlifes." + p.getName());
            playerlife --;
            this.getConfig().set("Config.players.playerlifes."+p.getName(), playerlife );
            saveConfig();
        }
    }
 

 

I wouldn't use configs for this, you should have your own class that manages this.

 

@1Rogue
But when I restart the server or something like this. I wanted to have my playerlifes saved.

 

@Ganga Serialize it.

 

Code:

    @EventHandler
    public void onPlayerDeath(PlayerDeathEvent event) {
        if(event.getEntity() instanceof Player){
            Player p = (Player)event.getEntity();
            int PlayerLives = getConfig().getInt(p.getName() + ".Lives");
            getConfig().set(p.getName() + ".Lives", PlayerLives - 1);
            saveConfig();
        }
    }

This should work.

 

@87pen
dude thats pretty much the same as I got

 

So just have your manager save the info to a config file when you shut down, and load it when you start back up! It'll be faster, too.

 

Mine works tho :/ or at least should.
