Example 1 with SpellRequirements

use of am2.spell.SpellUtils.SpellRequirements in project ArsMagica2 by Mithion.

the class SpellUtils method modifySpellRequirementsByAffinity.

    for (Affinity aff : affinities.keySet()) {
        float depth = affData.getAffinityDepth(aff);
        // calculate the modifier based on the player's affinity depth as well as how much of the spell is that affinity
        // how much does this affinity affect the overall mana cost?
        float effectiveness = affinities.get(aff);
        // how much will the player's affinity reduce the mana cost? (max 50%)
        float multiplier = 0.5f * depth;
        float manaMod = manaCost * effectiveness;
        manaCost -= manaMod * multiplier;
