HashMap Help!

Hello dear Bukkit Coders and Bukkit Code Seekers. I really need some help right now! I am trying to save my credits to the default configuration file, but I only have the HashMap. I am trying to load and save a HashMap. For instance, if i was to kill a player, then in the config it sets an amount for killing the player (I set the amount) and I already have the scoreboard setup on my server, so i need to figure out how to load the players credits through a scoreboard.

So let's recap.

What i want is: How to set a hashmap or add numbers to the config when a player kills another player they get credits, which i will have in the code at the bottom.

Second. I want to load the players credits on my scoreboard, now for this i just need to know how to load the players credits from the config file.

Here is my code:

Code:java

 
 public static HashMap<String, Integer> credits= new HashMap<String, Integer>(); @EventHandler
public void getCredits(PlayerDeathEvent event){
Player player = event.getEntity().getPlayer();
Player killer = event.getEntity().getKiller();
 
if (event.getEntity().getKiller() instanceof Player) {
 
//Set a number of credits here.
killer.getServer().broadcastMessage(player.getName() + "was whooped to death by " + killer.getName());
 
}
 
}
 
 

That's about all the code that I have started out with, i have searched on the forums and never got any luck. I would like any help involving this. Thank you!

Anyone?!

java wont magically add or remove values from hashmap, there are methods that must be invoked in order to alter object state.

 

Ok i get were you are going, but this isn't any help to what i am trying to get to.

 

your code have nothing with config or hashmap or scoreboard.

i just can't understand what wrong with it and what you want.

Read the topic please, it has what you are looking for.....

 

not going to spoonfeed you , start here http://docs.oracle.com/javase/7/docs/api/java/util/HashMap.html then update your code and we will continue mrgreen33gamer

a bit ahead of train - dont use UUID here
dont store player entity here

 

Yeah this just gives me information about how to make a proper HashMap, not how to load and save and HashMap :/

 

mrgreen33gamer That you need to implement yourself. Usually you want to iterate through the keys and save the values under a specific path in your file. Same goes for loading.
