[Guided Release] PvP script explained

#include "StdAfx.h"
#include "Setup.h"

//This struct will help us store the info we need for each player.
struct kill_info
{
	kill_info()
	{
		streak = 0;
		lguid = 0;
	}

	~kill_info() {}

	uint16 streak; //Stores how many kills we have in a row
	uint32 lguid; //Stores the last player killed guid to prevent abuse
};

static map<uint32, kill_info> kills;

void onPVP(Player * pPlayer, Player * pVictim)
{
        //We don't want this script to affect GMs.
	if(pPlayer->GetSession()->HasGMPermissions() || pVictim->GetSession()->HasGMPermissions())
		return;

        //We're storing the guids for easy access later
        //They're our indexes of the 'kills' map.
	uint32 p = pPlayer->GetGUIDLow();
	uint32 v = pVictim->GetGUIDLow();

	char msg[256] = ""; //This will store our message to the world
	if(p == v) //If the player's guid is the same as the victim guid
	{
		sprintf(msg, "%s just commited suicide! Pathetic!", pPlayer->GetName());
		sWorld.SendWorldWideScreenText(msg);
		kills[v].streak = 0;
		return;
	}

        //if we have a restricted no-pvp zone, define it here:
	if(pPlayer->GetMapId() == 169 && pVictim->GetMapId() == 169) //In this case it's Emerald Forest
	{
                //Time to do nasty stuff
		pPlayer->Reset_Spells();
		pPlayer->Reset_Talents();
		pPlayer->Reset_ToLevel1();
		pPlayer->EventTeleport(1, 16226.2, 16403.3, -63);
		pPlayer->BroadcastMessage("You were sent to jail for killing in the mall.");
		char msg[1024];
		snprintf(msg, 1024, "|cffff0000 %s the noob got kicked for fighting in the mall.", pPlayer->GetName());
		sWorld.SendWorldText(msg);
		pPlayer->Kick(60000);
		return;
	}

        //Now let's check if the player killed the same guy twice. If so, give him nothing
	if(kills[p].lguid == v)
		return;

	kills[p].streak++;

        //Now it's time to run checks like, if the victim had X kills in a row, do this and that.
        //I'm not including this, think up your own stuff ;)

        //In the end we set the player's lguid to the current victim, and reset the victim's streak. Don't put this before the checks, for obvious reasons.
	kills[p].lguid = v;
	kills[v].streak = 0;

        //This snippet changes the scale of the player. More kills = bigger scale. On my 
        //servers the more kills you have in a row, the more marks you're worth
        //So this is a good way to see pinatas ;)
	if(pPlayer->getRace == RACE_TAUREN) //Taurens start at 1.3 scale
		pPlayer->SetFloatValue(OBJECT_FIELD_SCALE_X, 1.3+((kills[p].streak-1)*0.2)); //Tricky line! We take the streak - 1 (so only double kills and up would count), and multiply by 0.2. So 5 kills are 1.3 + 0.8
	else
		pPlayer->SetFloatValue(OBJECT_FIELD_SCALE_X, 1+((kills[p].streak-1)*0.2)); //Same here, just the base scale is 1

} //Don't forget me!


//And of course we need to set it up now
void SetupPVP(ScriptMgr * mgr)
{
       //We register the onPVP function to the ON_KILL hook, so every time a player kills another player, the function gets called.
	mgr->register_hook(SERVER_HOOK_EVENT_ON_KILL_PLAYER, &onPVP);
}

Now all you need to do is add the appropriate lines in setup.h and setup.cpp and compile

Edit: Ouch this looks like a huge wall of code. I'll explode it later to smaller bits

Nice work, I love how you removed that one part to make the leechers think for themselves ^^

xD looks like a nice script i whish i new how to compile :'(

Yep, this isn't for leechers, this is mainly for people who want to learn how to make scripts, and give back to the community eventually.
