// Removes all auras from the Player due to a spell with spellId void Player::RemoveAurasDueToSpell(uint32 spellId) { // Iterate through all auras and remove if the source spell matches for (auto iter = m_auras.begin(); iter != m_auras.end();) { Aura* aura = iter->second; if (aura->GetSpellId() == spellId) { aura->Remove(); iter = m_auras.erase(iter); } else ++iter; } }In this example, we define a function called `RemoveAurasDueToSpell` that takes a spellId as a parameter. Then, we iterate through all the auras on the Player object and check if the source spell for each aura matches the passed in spellId. If it does, we remove the aura and erase it from the Player's aura list. This function can be used in various scenarios, such as removing all auras from a player caused by a specific boss spell in a raid encounter, or removing all debuffs from a friendly player in a PvP setting. As mentioned earlier, this function is part of the Blizzard C++ API and is included in the game development package library.
