[How to change HP and SP recovery]

Hello.

I was looking to change HP and SP recovery, both idle and when sitting.

I found some old threads but the code in the threads are old C code and not cpp.

 

I looked into rathena/src/map/status.cpp and have seen some code related to HP and SP regen while sitting. 

static int status_natural_heal(struct block_list* bl, va_list args)

 

But I am unsure if ths is the right place and what exactly I should change.

If I understood it correctly I would like to edit the following lines to adjust the sitting HP and SP recovery:

// for HP
rate = (int)(natural_heal_diff_tick * (sregen->rate.hp / 100.));

// for SP
rate = (int)(natural_heal_diff_tick * (sregen->rate.sp / 100.));

 

Any help would be appreciated.

Thanks.

Hello,
If you're running the latest rAthena:

In /conf/battle/player.conf
You may adjust the following to alter the time factor of regen for HP/SP:

// The time interval for HP to restore naturally. (in milliseconds)
natural_healhp_interval: 6000

// The time interval for SP to restore naturally. (in milliseconds)
natural_healsp_interval: 8000

An alternative but not recommended method source-side:

In /src/map/pc.cpp:
Replace:

//Character regen. Flag is used to know which types of regen can take place.
//&1: HP regen
//&2: SP regen
void pc_regen (map_session_data *sd, t_tick diff_tick)
{
	int hp = 0, sp = 0;

	if (sd->hp_regen.value) {
		sd->hp_regen.tick += diff_tick;
		while (sd->hp_regen.tick >= sd->hp_regen.rate) {
			hp += sd->hp_regen.value;
			sd->hp_regen.tick -= sd->hp_regen.rate;
		}
	}

	if (sd->sp_regen.value) {
		sd->sp_regen.tick += diff_tick;
		while (sd->sp_regen.tick >= sd->sp_regen.rate) {
			sp += sd->sp_regen.value;
			sd->sp_regen.tick -= sd->sp_regen.rate;
		}
	}

	if (sd->percent_hp_regen.value) {
		sd->percent_hp_regen.tick += diff_tick;
		while (sd->percent_hp_regen.tick >= sd->percent_hp_regen.rate) {
			hp += sd->status.max_hp * sd->percent_hp_regen.value / 100;
			sd->percent_hp_regen.tick -= sd->percent_hp_regen.rate;
		}
	}

	if (sd->percent_sp_regen.value) {
		sd->percent_sp_regen.tick += diff_tick;
		while (sd->percent_sp_regen.tick >= sd->percent_sp_regen.rate) {
			sp += sd->status.max_sp * sd->percent_sp_regen.value / 100;
			sd->percent_sp_regen.tick -= sd->percent_sp_regen.rate;
		}
	}

	if (hp > 0 || sp > 0)
		status_heal(&sd->bl, hp, sp, 0);
}

With:

void pc_regen (map_session_data *sd, t_tick diff_tick)
{
    int hp = 0, sp = 0;
    int regen_rate_modifier = 1; // Normal rate

    // Check if the player is sitting to apply a rate modifier [NimbleStorm]
    if (pc_issit(sd)) {
        regen_rate_modifier = 2; // Increase tick rate by a factor of 2, adjust as needed [NimbleStorm]
    }

    if (sd->hp_regen.value) {
        sd->hp_regen.tick += diff_tick * regen_rate_modifier; // Apply modified rate
        while (sd->hp_regen.tick >= sd->hp_regen.rate) {
            hp += sd->hp_regen.value;
            sd->hp_regen.tick -= sd->hp_regen.rate;
        }
    }

    if (sd->sp_regen.value) {
        sd->sp_regen.tick += diff_tick * regen_rate_modifier; // Apply modified rate
        while (sd->sp_regen.tick >= sd->sp_regen.rate) {
            sp += sd->sp_regen.value;
            sd->sp_regen.tick -= sd->sp_regen.rate;
        }
    }

    if (sd->percent_hp_regen.value) {
        sd->percent_hp_regen.tick += diff_tick * regen_rate_modifier; // Apply modified rate
        while (sd->percent_hp_regen.tick >= sd->percent_hp_regen.rate) {
            hp += sd->status.max_hp * sd->percent_hp_regen.value / 100;
            sd->percent_hp_regen.tick -= sd->percent_hp_regen.rate;
        }
    }

    if (sd->percent_sp_regen.value) {
        sd->percent_sp_regen.tick += diff_tick * regen_rate_modifier; // Apply modified rate
        while (sd->percent_sp_regen.tick >= sd->percent_sp_regen.rate) {
            sp += sd->status.max_sp * sd->percent_sp_regen.value / 100;
            sd->percent_sp_regen.tick -= sd->percent_sp_regen.rate;
        }
    }

    if (hp > 0 || sp > 0)
        status_heal(&sd->bl, hp, sp, 0);
}

Good luck. You can do it.
