Simple CointSystem.

How do i make a simple per player Coinsystem?
When you get a zombiekill, you get 1 coin.
And how do i remove coins of a player?

 

Hashmap.

 

Try to learn how to use vault, its a very good api

 

Can someone give me a simple example ?

 

A HashMap is a list that associates two values together like a dictionary. In a dictionary, you have words and their associated definitions. In a HashMap, those are called keys and values, respectively. You'd want the player name to be the key and the number of coins they have to be the value. So you would make that hashmap like this:

Code:

HashMap<String, Integer> mymap = new HashMap<String, Integer>();

That's more than enough info, I'm sure you can find the rest out using google.

 

I know, i can do it with hashmaps. but how..?

it maybe helps!

 

I don´t understand it exactly...
Do you use Hashmap or Config ?

Anyone ?

Just an example:

Classes:

CoinHandler
TestCommand

CoinHandler

Code:

private static HashMap<String, Integer> coins = new HashMap<String, Integer>();
 
public static int getCoins(String player) {
    return coins.get(player);
}
 
public static void addCoins(String player, int amount) {
    coins.put(coins.get(player) + amount);
}
 
public static void removeCoins(String player, int amount) {
    coins.put(coins.get(player) - amount);
}

Just use those methods in your TestCommand (usually in all your classes) to use the CoinSystem.

 

If you want to keep it stored, even after restarting the server or reloading, use a configuration file;

Code:

    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e) {
        if (!getConfig().contains(e.getPlayer().getName())) {
            getConfig().set(e.getPlayer().getName() + ".coins", 0);
            saveConfig();
        }
    }
 
#This code will set the coins of a user to 0 if they haven't joined before.

Code:

    @EventHandler
    public void o(final EntityDamageByEntityEvent e) {
            Bukkit.getScheduler().scheduleSyncDelayedTask(this, new BukkitRunnable() {
                @Override
                public void run() {
                    if (e.getEntity().isDead() && !(e.getEntity() instanceof Player)) {
                    Player p = (Player) e.getDamager();
                    getConfig().set(p.getName() + ".coins", getConfig().getInt(p.getName() + ".coins") + 1);
                    saveConfig();
                }
            }
        }, 1L);
    }
 
#This code will add 1 coin when a player kills an entity that's not a player (A mob) and stores & updates the player's coins.

 

Great! Thank you!
I did choose the config option, but how can i show someone his coins with a command like /voxelcoins ?

Can i do it with:

Code:java

if (commandLabel.equalsIgnorecase("Voxelcoins"){
    player p = (Player) sender;
    p.sendMessage(ChatColor.GRAY + "Coins: " + (coins.get(p));

Test your command, see if it works. If not, paste your errors here

 

quit the bumping already.

But I assume the coins is a hashmap? you should use p.getName(), or else you are using a player object as a string (which will result in a pointer as the given string to check in the hashmap)

 

Do you want to use sql db to store the coins?

 

Dr_Bunsen It´s in a config.
