So i will say that you created your ArcEmu server from scratch and all...
So you are new to all the scripting of the ArcEmu Core and you want to use flying mounts everywhere in the game.
So at first, open the SVN Checkout Folder/trunk/src
Open the folder named arcemu-world.
!!!NOTE!!! : You MUST NOT open and edit the C++ files without advice from someone that already did what you are trying to do!
So now you are in SVN Checkout Folder/trunk/src/arcemu-world
There is a lot of C++ Files. Open the file named Unit.cpp
now inside the C++ file, search for :
CODE-BOX
if(m_mapId!=530
You should find something like this:
CODE-BOX
if(m_mapId!=530 && (m_mapId!=571 || (IsPlayer() && !((Player*)this)->HasSpellwithNameHash(SPELL_HASH_COLD_WEATHER_FLYING))))
Now you must edit this line for the use of flying mounts.
So to use the flying mounts everywhere, change it to this:
CODE-BOX
if(m_mapId!=530 && m_mapId != 0 && m_mapId != 1 && (m_mapId!=571 || (IsPlayer() && !((Player*)this)->HasSpellwithNameHash(SPELL_HASH_COLD_WEATHER_FLYING))))
!!!NOTE!!! : You can use the flying mounts everywhere, but if you want to use in northrend, you must now the spell Cold weather Flying
Congrats! You just edited the core for the flying mounts!
