I'm able to create a simple jump in a side scroller (rise and fall at the same rate), but I'm for some reason unable to get a nice "rise at a slower and slower rate, peak, fall at a faster and faster rate" smooth arc. Does anyone have any ideas that might point me in the right direction? So far I have this, which rises at a slower(ish) rate over time, peaks smoothly, but then falls at a pretty slow rate. When a jump is performed by pressing a key, yVel is set to -10 and increases until it reaches just under 10 which does cause the object to rise then fall, just not how I'm looking for.
EDIT: Jeez, I hate it when a solution is so simple it's the last thing you think of. I've got it working now, but if anyone wants to contribute your own ideas of one, feel free to go ahead.
