Help Understanding FindAffect Function in C++ Code When Using Blend Item

[rejenzuxx4754 1]

Hi everyone,

I’m currently working on some C++ code for Metin2 and came across a section I’m having trouble understanding. Here’s the relevant part of the code:

if (FindAffect(affect_type, apply_type))
{
    ChatPacket(CHAT_TYPE_INFO, LC_TEXT("ÀÌ¹Ì È¿°ú°¡ °É·Á ÀÖ½À´Ï´Ù."));
}
else
{
    if (FindAffect(AFFECT_EXP_BONUS_EURO_FREE, POINT_RESIST_MAGIC))
    {
        ChatPacket(CHAT_TYPE_INFO, LC_TEXT("ÀÌ¹Ì È¿°ú°¡ °É·Á ÀÖ½À´Ï´Ù."));
    }
    else
    {
        AddAffect(affect_type, apply_type, apply_value, 0, apply_duration, 0, false);
        item->SetCount(item->GetCount() - 1);
    }
}

 

I understand the general structure of checking for existing effects before applying new ones, but I’m specifically puzzled by the second condition:
 

if (FindAffect(AFFECT_EXP_BONUS_EURO_FREE, POINT_RESIST_MAGIC))

Could someone explain the purpose of this specific "FindAffect" check? Thanks in advance!

That's part of the ITEM_BLEND, which are the potions that offer attack, critical, magic resistance, etc.

It basically says that you can't use any other potion of that kind(ITEM_BLEND) after using a magic resistance one. 

 

Why? No idea what the actual intention was, but I remember that all the players were using that potion last because of this.

Can you remove it? Yes, and it would probably make sense to do so.

thank you for the answer.

In the description of the blend item that provides magic resistance, I noticed a statement about it being increased by a percentage. However, when I examined the code and the proto, it was being increased by a fixed value.

The only explanation I could find is that if the blend item increases magic resistance by a percentage, it prevents excessive value increases that might occur if magic resistance has already been boosted by the "AFFECT_EXP_BONUS_EURO_FREE" type of affect.

i think i'll follow this way.
