The title says it all.
To picture: think of say, the trajectory of a fountain. I'd like the bullet to rise up and fall in a parabolic arc.
Which math expression would I use to achieve this affect? I would like to avoid using the Physics behavior + gravity or "cheating" with Platform behavior, because I would like the bullets to ignore solids.
Or would I use Custom Movement, setting up a time of upward velocity and downward velocity, while adding a little horizontal acceleration? That seems a little messy, which is why I am asking if it can be done with a math expression.
Thanks in advance for any help.
