Config set not working

I am creating a config per player and it does that but is not setting the "Emeralds" equal to 1.
Here is my code:

Code:java

 @EventHandler
public void JoinEvent(PlayerJoinEvent event){
Player p = event.getPlayer();
File userDir = new File(this.getDataFolder() + File.separator + "Users");
if(!userDir.exists()){
userDir.mkdir();
}
File playerFile = new File(this.getDataFolder() + File.separator + "Users" + File.separator + p.getName() + ".yml");
FileConfiguration fc = YamlConfiguration.loadConfiguration(playerFile);
fc.set("Emeralds", 1);
saveConfig();
if(!playerFile.exists()){
try {
playerFile.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
}
}

There are no errors in the console



EDIT: NEW PROBLEM

 

You're calling "saveConfig()" which will save your "config.yml", not your player file:

Code:java

try {
    fc.save(playerFile);
} catch (IOException ex) {
    //couldn't save
}

Also, why are you checking if the file exists before loading it as a FileConfiguration? That should likely come before that.

 

Thanks, it works now

I now have another problem:
When I try to grab "Emeralds" it's a 0
This is what Im using to grab it:

Code:java

File playerFile = new File(this.getDataFolder() + File.separator + "Users" + File.separator + player.getName() + ".yml");
FileConfiguration fc = YamlConfiguration.loadConfiguration(playerFile);
int intbalance = fc.getInt(player.getName()+"Emeralds");
String balance = String.valueOf(intbalance);

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

The problem is:

Code:java

fc.set("Emeralds", 1);

Code:java

fc.getInt(player.getName()+"Emeralds");

What you should have to get the int:

Code:java

fc.getInt("Emeralds");
