You'll need to hook in to Vault, by adding it as an external Jar using the program of your choice

Once you've done that, you'll have access to methods such as getBalance, which you can then use to check if the player has enough money.

 

(Assume getMoney(Player player); is a method you have made that returns the money of the player)

You could do something like this:

Code:java

public final int COST = 5;
 
@EventHandler
public void onCommand(PlayerCommandPreprocessEvent event){
     if(!event.getMessage().equalsIgnoreCase("test")) return;
     Player player = event.getPlayer();
     if(!getMoney(player) >= COST){
          player.sendMessage("Not enough money!");
          event.setCancelled(true);
          return;
     }
     // subtract money
}

I know that getting the message and seeing if it equals "test" isn't a very good way to check the command given seeing as the player could simply add in another argument and bypass this. That could be fixed later.

If you are not using your own economy system, hooking into vault is the best way to do it.

 

xMrPoi Why "if not greater than or equal to" rather than a simple "if less than"?

 

Code:java

public class Main extends JavaPlugin {
public final int COST = 100;
 
public void onEnable(){
System.out.println("[Rankup] Plugin Enabled!");
getServer().getPluginManager().registerEvents((Listener) this, this);
saveDefaultConfig();
 
}
 
@EventHandler
public void onCommand(PlayerCommandPreprocessEvent event){
if(!event.getMessage().equalsIgnoreCase("rankup")) return;
 
Player player = event.getPlayer();
if(!getMoney(player) >= COST){
 
player.sendMessage(getConfig().getString("MSG.Line1").replace("&", "§"));
 
event.setCancelled(true);
return;
 
}
 
 
}
 
public void onDisable(){
System.out.println("[Rankup] Plugin Disabled!");
}
}

Not work





EDIT: add public final int COST= 100;

 

Don't just copy paste code people put on here, it's usually pseudo code. Anyway, there is no getMoney() method in your class unless you import it or create it. This might help.

 

Out of topic but please don't use System.out.println(""); instead use getLogger().info("");
