Using Vault?

Hey i developing a plugin that works with signs and charges players money when they right click a sign(certain sign) and i need to how i can block the regular function of the plugin if the player doesn't have enough money. Lemme explain better with a code snippet:

PHP:

f(player.hasPermission("mclevelup.buy." + s.getLine(0).toLowerCase())
                                || player.hasPermission("mclevelup.buy.*")){
                            if(McLevelUp.econ.getBalance(e.getPlayer().getName()) > 0) {
                            e.setCancelled(true);
                            mcMMO.getPlayerProfile(player).addXPOverrideNoBonus(
                                    SkillType.valueOf(s.getLine(1).toUpperCase()), Integer.valueOf(s.getLine(2)));
                            mcMMO.checkXp(player, SkillType.valueOf(s.getLine(1).toUpperCase()));
                            player.sendMessage(ChatColor.GREEN  + " Successfully Bought " + s.getLine(2) + " of " + s.getLine(1).toLowerCase() + " xp");
                            if(!player.hasPermission("mclevelup.bypass.charge")) {     
                            McLevelUp.econ.withdrawPlayer(e.getPlayer().getName(), Double.valueOf(s.getLine(3)));
                            return;     
                            }
                            } else {
                                player.sendMessage(ChatColor.RED + " Insufficient funds");
                            }
                    } else {
                        player.sendMessage(ChatColor.RED + "You dont have permission for " + s.getLine(1).toLowerCase() + " signs");
                    }

Getting the balance of a player:
vault.getEconomy().getBalance(player.getName()).amount

 

Yeah i know but with essentials economy, it still lets you buy stuff when you shouldn't be able to be cause vault doesn't go in negatives.

 

You can add a check for this:

Code:

if(balance > cost) {
     balance -= cost;
     // And set the balance back to Vault
} else {
     player.sendMessage("You don't have enough money!");
}

 

It only lets you go negative because Essentials allows Loans. It wont let your account go negative if you turn off loans in essentials.

 

Yeah thats what i was thinking this morning in school. Sleaker I know but i wasn't op'd when i tried that.
