[Release] buy() method

[m. Tanner]

Put this in MapleCharacter.java

public void buy(int itemid, int quantity, int price)
    {
        long totalPrice = price * quantity;
        long mesosNeeded = totalPrice - this.getMeso();
        int amtOfAeros = this.getItemQuantity(4000313, false);
        if(totalPrice <= Integer.MAX_VALUE){
            if(this.getMeso() >= totalPrice)
            {
                this.gainMeso((int)-totalPrice, true);
                MapleInventoryManipulator.addById(this.getClient(), itemid, (short)quantity);
            }else{
                mc.dropMessage("You do not have enough mesos. You need "+mesosNeeded+" more mesos.");
                return;
            }
        }else{
            int aerosNeeded = (int)(totalPrice / Integer.MAX_VALUE);
            int extraMesos = (int)(totalPrice - (aerosNeeded * Integer.MAX_VALUE));
            if(amtOfAeros < aerosNeeded)
            {
                mc.dropMessage("The total price for this purchase is above the max Meso value, We checked for Aeros to see if you could use those to pay, but you did have enough of those either.");
            }else{
                this.gainItem(4000313, (short)-aerosNeeded, false);
                this.gainMeso(-extraMesos, true);
                MapleInventoryManipulator.addById(this.getClient(), itemid, (short)quantity);
                mc.dropMessage("You used "+aerosNeeded+" Aeros and "+extraMesos+" Mesos to pay for this/these item(s).");
            }
        }
    }

This basically will make your player buy an item for however many mesos multiplied by the quantity. It also checks if the overall price is over max mesos and takes away Golden Maple leafs instead, and the difference in mesos.

Golden Maple Leafs are usually worth 2 Billion mesos in most servers. (We call them Aeros in AeroStory)

Command to test it-

else if(splitted[0].equalsIgnoreCase("!buy"))
        {
            if(splitted.length == 4){
                int itemid = 0;
                short quantity = 0;
                int price = 0;
                try{
                    itemid = Integer.parseInt(splitted[1]);
                    quantity = (short)(Integer.parseInt(splitted[2]));
                    price = Integer.parseInt(splitted[3]);
                }catch(Exception e){
                    mc.dropMessage("Error parsing integers.");
                    return;
                }
                try{
                    player.buy(itemid, quantity, price);
                }catch(Exception e){
                    mc.dropMessage("ERROR");
                    mc.dropMessage(""+e);
                }
            }else{
                mc.dropMessage("<syntax> !buy <itemid> <quantity> <price>");
                return;
            }
        }

MAKE SURE YOU DEFINE THE COMMAND!

You can use this in maybe an npc script-

cm.getChar().buy(itemid, quantity, priceforeach);
