How to make MATK = 1 in status_calc_pc_ ?

Question

Hello,

I'm trying to make MATK = 1 for players while on a certain map (my_map). I've had success with all the other stats using this method, but MATK doesn't seem to change.

static int status_calc_pc__post(int ret, struct map_session_data *sd, enum e_status_calc_opt opt)
{
	nullpo_retr(-1, sd);
	if (strcmpi(map->list[sd->bl.m].name, "my_map") != 0)
		return ret;

	struct status_data *bstatus = &sd->base_status;

	bstatus->max_hp = 40;
	bstatus->matk_max = 1;
	bstatus->matk_min = 1;

	return ret;
}

#include "common/hercules.h"

HPExport struct hplugin_info pinfo = {
	"atk1",
	SERVER_TYPE_MAP,
	"0.1",
	HPM_VERSION,
};

int status_get_matk_post( int retVal, struct block_list *bl, int flag ) {
	if ( retVal != 0 )
		return retVal;
	return retVal;
}

int status_calc_pc_post( int retVal, struct map_session_data *sd, enum e_status_calc_opt opt ) {
	if ( retVal != 0 )
		return retVal;
	if ( strcmp( mapindex_id2name(sd->mapindex), "guild_vs2" ) )
		return 0;
	struct status_data *bstatus = &sd->base_status;
	clif->message( sd->fd, "Run" );
//	struct status_data *bstatus = status->get_status_data(&sd->bl);
	bstatus->max_hp = 40;
	bstatus->matk_max = 1;
	bstatus->matk_min = 1;
	sd->battle_status.matk_max = 1;
	sd->battle_status.matk_min = 1;
	sd->base_status.matk_min = 1;
	sd->base_status.matk_max = 1;
//	sd->battle_status.max_hp = 99;
	bstatus->hit = 1;
	bstatus->flee = 1;
	ShowDebug( "%d %d", status_get_matk_min(&sd->bl), status_get_matk_max(&sd->bl) );
	return 0;
}

HPExport void plugin_init(void) {
	addHookPost( status, calc_pc_, status_calc_pc_post );
}

doesn't work, ShowDebug even shows I'm having 1 1 value ... yet still dealing over hundreds of damage to poring

tell you what ... use my OnPCStatCalcEvent ...

OnPCStatCalcEvent:
	bonus bMatkRate, -100;
//	bonus bMatk, -999;
	end;

there is a reason why this modification is so famous ...

Well I've done few changes to this, I used same method as @AnnieRuru but as a plugin, first hercules provides us with the amazing status->pc_calc_additional which is meant for plugins, it's placed right after Equipment parse so it would not overwrite the value the plugin set, and then the plugin set the matk rate to 0, and tada!

I've also changed map check to check the id of the map instead, this is simpler, faster and also allowed a run time check for if you accidentally put a wrong map name (check server_online function), and it's tested :3 works as charm!

OnPCStatCalcEvent is very famous modification,
if you do forum search in rathena or hercules, you can even get some custom stuffs that only applicable with this mod

 

if (sd == NULL) // I don'r prefer usage of nullpo in hooks, unless we're replacing a function multiaple nullpo reports can turn confusing.

well, personally, Pre-Hook needs nullpo, Post-Hook doesn't need ... though

hahaha, yeah I go change that XD
