C++ attempt to call method 'addWings' (a nil value)

[luanmaximus123]

Hi guys, I'm trying to add the addWing function, but something seems to be wrong. I don't know what it could be. Can someone please help me?

player.cpp

bool Player::addWing(uint8_t wingId)
{
    if (!g_game.wings.getWingByID(wingId)) {
        return false;
    }

    const uint8_t tmpWingId = wingId - 1;
    const uint32_t key = PSTRG_WINGS_RANGE_START + (tmpWingId / 31);

    int32_t value;
    if (getStorageValue(key, value)) {
        value |= (1 << (tmpWingId % 31));
    }
    else {
        value = (1 << (tmpWingId % 31));
    }

    addStorageValue(key, value);
    return true;
}


bool Player::addAura(uint8_t auraId)
{
    if (!g_game.auras.getAuraByID(auraId)) {
        return false;
    }

    const uint8_t tmpAuraId = auraId - 1;
    const uint32_t key = PSTRG_AURAS_RANGE_START + (tmpAuraId / 31);

    int32_t value;
    if (getStorageValue(key, value)) {
        value |= (1 << (tmpAuraId % 31));
    }
    else {
        value = (1 << (tmpAuraId % 31));
    }

    addStorageValue(key, value);
    return true;
}

In here
registerMethod("Player", "addWing", LuaScriptInterface::luaPlayerAddWing);

Thats how you will use that so: player:addWing(1)
