Anti-mob System

[serjtk]

Hello all,

I've been trying to create a system wich in a 2x1, 3x1, 4x1 (etc..) situation, mobers wil receive a debuff like decrease agi.

This is an example made by chat gpt/deep seek. This one does not show any problems on rAthena, but no working at all.

-    script    AntiGankSystem    -1,{
OnPCAttackEvent:
    if (strcharinfo(3) == "guild_vs3") { // Aplica apenas nesses mapas
        set .targetID, getcharid(0);
        set .attackers, 0;

        // Obtém lista de jogadores próximos no mesmo mapa PvP
        getmapxy .@map$, .@x, .@y, 0;
        setarray .@players, getmapunits(BL_PC, .@map$);

        for (set .@i, 0; .@i < getarraysize(.@players); set .@i, .@i + 1) {
            if (getcharid(0, .@players[.@i]) != .targetID) {
                if (checkvending(.@players[.@i]) == 0) { 
                    set .attackers, .attackers + 1;
                }
            }
        }

        // Se houver 2 ou mais atacantes no mesmo alvo, aplica penalidade
        if (.attackers >= 2) {
            sc_start SC_DECREASEAGI, 10000, 10;  // Reduz a velocidade de movimento
        }
    }
    end;
}
 

Could you guys please make some comments?

Thank you.

Unfortunately, OnPCAttackEvent alone doesn't give you all the context you need. You might consider combining OnPCAttackEvent with a timer or periodic check to aggregate attack data.

Use src mod for better tracking. If you're open to modifying the source (src), you could implement a true anti-gank system by tracking attackers on the target side, which is more reliable.

I don't have a script solution, but I tried around a bit in src.

In battle.cpp in the battle_damage function, if you find:

	if (src)
		sd = BL_CAST(BL_PC, src);

and replace it with:

	if (src) {
		sd = BL_CAST(BL_PC, src);
		unit_data* ud = unit_bl2ud(target);
		if (src->type == BL_PC && target->type == BL_PC && ud != nullptr && ud->target_count >= 2)
			status_change_start(target, src, SC_DECREASEAGI, 10000, 10, 0, 0, 0, 10000, SCSTART_NOAVOID);
	}

It's kinda working. However, it only counts autoattackers, not players that use skills on the target. If there are already 2 auto attackers and someone attacks with skill, they also get cursed, though.

Would be easier to do if we had the official system of counting attackers that adds them to a list and then deletes them after 3000ms again.
