Growing spells

[Scorpious2k]

Since jpyou127 asked how it is done, I thought I would explain. It's not that complicated, really.

I'll start with an explanation. On our server, all custom code is bracketed with #ifdef SCORPIOUS2K / #else / #endif which makes it easier to find and maintain.

To start with, I added the following function to spell_effects.cpp

#ifdef SCORPIOUS2K
// make spells friendlier - adjust for class/grow with level
int32 AdjustEffectForGrowth(int32 dmg, Mob* caster, int16 spellid)
{

	// printf("adjusting effect for class\n");
	if (caster->IsNPC() && caster->GetOwnerID() == 0)
	{
		// printf("IsNPC\n");
		return dmg;
	}

	// make spells grow starting at level when they can get the spell
	int caster_level = caster->GetLevel() - (int)spells[spellid].classes[caster->GetClass() - 1];
	if (caster_level < 1)
	{	// probably a clicky
		caster_level = caster->GetLevel() / 6;
	}

	int tmp;
	if (caster->GetCasterClass() != 'N')
	{
		// printf("Caster class: ");
		if (caster->IsWarriorClass())
		{	// hybrid
			// printf("hybrid\n");
			tmp = (dmg*(100 + caster_level)) / 100;
		}
		else
		{	// pure caster
			// printf("pure\n");
			tmp = (dmg*(100 + (caster_level * 2))) / 100;
		}
	}
	else
	{	// melee
		// printf("Melee class\n");
		tmp = (dmg*(100 + (caster_level / 3))) / 100;

	}
	if (tmp>24000)
	{
		tmp = 24000 - (tmp % 1000) + (caster_level * 2);
	}

	return tmp;

}
#endif

Then all you have to do is add the function calls to Mob::SpellEffect, for example

			case SE_CurrentHP:	// nukes, heals; also regen/dot if a buff
			{
#ifdef SPELL_EFFECT_SPAM
				snprintf(effect_desc, _EDLEN, "Current Hitpoints: %+i", effect_value);
#endif
				// SE_CurrentHP is calculated at first tick if its a dot/buff
				if (buffslot >= 0)
					break;

				// for offensive spells check if we have a spell rune on
				int32 dmg = effect_value;
				if(dmg < 0)
				{
					if (!PassCastRestriction(false, spells[spell_id].base2[i], true))
						break;

					// take partial damage into account
					dmg = (int32) (dmg * partial / 100);

					//handles AAs and what not...
					if(caster) {
						dmg = caster->GetActSpellDamage(spell_id, dmg, this);
						caster->ResourceTap(-dmg, spell_id);
					}

#ifdef SCORPIOUS2K
					// growing spells
					dmg = AdjustEffectForGrowth(dmg, caster, spell_id);
#endif

					dmg = -dmg;

that one line makes HP changes of the SE_CurrentHP type grow based upon the spell, it's req level, and the current level of the castor.

Like I said. Simple.

Thank you sir! Going to give this a shot!
