I was wondering if it is possible to convert a projectile motion(velocity, direction, etc) into a (parabolic) equation. I am programming a motion planner to use in a simple 'game' that I am making. A formula would be appreciated. I was thinking something like http://img99.imageshack.us/img99/187/eq220d30dcno9.png [Broken] To get the x value I am using the range formula I am then using a similar formula to calculate the total time of flight. Then I am dividing the range by the total time of flight.
