Hey!
There are a few really cool custom mounts out there, but not a guide or a release. So I started to make a unique vehicle on my own.
Figured out I can swap spells in creature_proto, works but there are bugs. Instant cast spell (for example charge) is not instant and it is not because the server lag. Some spells just simply can not be casted, other ones give me the 'invalid target' error. But found some that works as intended. I could also edit the displayid, the mouseover icon and the vehicles's faction in the DB.
The next part was the dbc 'edit'. Well it was not a big deal all I did is I removed 2 seats and the UI that shows up in game. (so my little being can't carry 3 players and doesn't look like a demolisher on the screen :P)
So all of these things work more -or less buggy.
I hope it's not just me who's interested in making not blizzlike vehicles and I'm looking forward too see your suggestions (what should I do to make it more unique, to bypass the 'invalid target' and such). If you need help with the things I've done by now just ask
