Yeah! Thats pretty literal right there. BOTTLE ROCKET. Im gonna teach you how to make a gameobject with a displayid of a bottle that'll send you flying.
So go into your database (mine being Heidi SQL, doesnt really matter). Go into the Ascent section, and then into the gameobject_names subsection. Get a new record going, and insert it just like this:
"400000000, 22, 228, Bottle Rocket, 43621, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,"
You can name it whatever you want, but thats all you need. So just go find a spot with a lot of open areas, spawn that puppy, and get ready to glide!
Personlly, i made a bit of a game hopping along the three ships off the shore of Isle of Quel'Danas. But its up to you!
