is it possible to make an AoE magic skill to target specific race only?

[laonglaing]

as what the title ask, im trying to modify some AoE skills that damages specific race only in the area. saw this method -> status_get_status_data(bl) but im unable to use it in this specific line of code since it directly targets to to BC_ENEMY already
                map_foreachinallarea(skill_area_sub,
                    src->m, x - i, y - i, x + i, y + i, BL_CHAR,
                    src, skill_id, skill_lv, tick, flag | BCT_ENEMY | 1,
                    skill_castend_damage_id);

im trying to modify skills in skill.cpp under below method which doesn't pass the information of bl.
int skill_castend_pos2(struct block_list* src, int x, int y, uint16 skill_id, uint16 skill_lv, t_tick tick, int flag)

any idea or suggestion for this?
