OnNPCAttackedEvent [ need help of src devs ]

[Lord Ganja]

I've been doing this for a while now. I can't finish it since i'm not actually good at src mod. Actually I posted something here before.

 

Now I came up with these codes but it isn't working well. I got the idea from here.

 

In this topic, OnNPCAttackedEvent = when a monster received a damage.

 

Questions:

1) will this code use too much memory since it will trigger each time a mob is hit?

 

2)  if I use a script like this, will it still consume the same amount of memory?

                     OnNPCAttackedEvent:

                               if( @attackedrid != 1002 ) end;

 

3) As i've stated in this post, is it possible to only trigger OnNPCAttackedEvent to the mobs who are spawned with specific or "OnThisMob" event label?

 

mob.c

//Call when a mob has received damage.
void mob_damage(struct mob_data *md, struct block_list *src, int damage)
{
+	// OnNPCAttackedEvent
+	struct map_session_data *sd = NULL, *tmpsd[DAMAGELOG_SIZE];
+	memset(tmpsd,0,sizeof(tmpsd));
+	if ( src && src->type == BL_PC )
+	{
+		sd = (struct map_session_data *)src;
+	}

	if (src && damage > 0) { //Store total damage...
		if (UINT_MAX - (unsigned int)damage > md->tdmg)
			md->tdmg += damage;
		else if (md->tdmg == UINT_MAX)
			damage = 0; //Stop recording damage once the cap has been reached.
		else { //Cap damage log...
			damage = (int)(UINT_MAX - md->tdmg);
			md->tdmg = UINT_MAX;
		}
		if ((src != &md->bl) && md->state.aggressive) //No longer aggressive, change to retaliate AI.
			md->state.aggressive = 0;
		//Log damage
		mob_log_damage(md, src, damage);
		md->dmgtick = gettick();

+		// OnNPCAttackedEvent
+		if(sd) { // if I didn't use if(sd) the map-server crash when a pet attacks a monster
+			pc_setreg(sd, add_str("@attackerrid"), sd->bl.id);
+			pc_setreg(sd, add_str("@attackedrid"), md->mob_id);
+			npc_event_doall_id("OnNPCAttackedEvent", sd->bl.id);
+		}
	}

	if (battle_config.show_mob_info&3)
		clif_charnameack(0, &md->bl);

#if PACKETVER >= 20120404
	if( battle_config.monster_hp_bars_info){
		int i;
		for(i = 0; i < DAMAGELOG_SIZE; i++){ // must show hp bar to all char who already hit the mob.
			struct map_session_data *sd = map_charid2sd(md->dmglog[i].id);
			if( sd && check_distance_bl(&md->bl, &sd->bl, AREA_SIZE) ) // check if in range
				clif_monster_hp_bar(md, sd->fd);
		}
	}
#endif

	if (!src)
		return;

	if( md->special_state.ai == AI_SPHERE ) {//LOne WOlf explained that ANYONE can trigger the marine countdown skill. [Skotlex]
		md->state.alchemist = 1;
		mobskill_use(md, gettick(), MSC_ALCHEMIST);
	}
}

Thanks in advance for those who can help!
