Hi Glboom,
The reason that you are sticking to the surface is because the Character class doesn’t use actual physics; it’s faked. The Vehicle class works like you would expect because it is physics based.
So to accomplish this, you would need to either use a physics based class (like the Vehicle class) and fake it into a character like setup.
Or take the Character class and add a ‘launch’ functionality to it. Here is a forum post where a user did just that.
Cheers,
TJ
