Thread: [C++] Bounty Hunter

Long ago, a script was made with a similar purpose as this one. I have since updated it and rewritten many pieces of it and added more features. It does however, lack the assassin unit which it once had.

If you think the script should have something else, feel free to let me know. I will consider any idea put towards this script.

Code:

#include "Stdafx.h"
#include "Setup.h"

class BountyHunter : public GossipScript
{
public:
        void GossipHello(Object* pObject, Player* Plr, bool AutoSend)
    {
        GossipMenu *Menu;
                if(Plr->CombatStatus.IsInCombat())// Checks for combat
                {
                        Plr->BroadcastMessage("You are in combat!");
                        return;
                }
                else
                {
                        objmgr.CreateGossipMenuForPlayer(&Menu, pObject->GetGUID(), 95768, Plr);
                        Menu->AddItem(0, "I would like to place a bounty on someone for 400g", 0, 1);
                        Menu->AddItem(0, "I would like to see the posted bounties", 1);
                        if(Plr->GetSession()->HasPermissions()) //Checks for GM permissions
                        {
                                Menu->AddItem(0, "Clear all bounties", 2);
                        }
                }
                if(AutoSend)
            Menu->SendTo(Plr);
        }

I've also commented it so you can see what does what.

Here is the sql query that goes along with the script.

Code:

DROP TABLE IF EXISTS `huntedlist`;

CREATE TABLE `huntedlist` (
`guid` int(11) NOT NULL,
`name` varchar(30) COLLATE latin1_general_ci NOT NULL,
`listed` int(11) NOT NULL,
PRIMARY KEY (`guid`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci;
