Added the position tag, started the seed for projectile-physics (see the start from http://chat.stackexchange.com/transcript/message/858147#858147). I'll leave the 2d-physics for later elaboration. ♪

Determing an object's position along a curve over time

I have some objects in my game which are "thrown". At the moment I am trying to implement this by having these objects follow a parabolic curve. I know the start point, the end point, the vertex and the speed of the object.

  1. How can I determine at any given time or frame what the x & y co-ordinates are?
  2. Is a parabolic curve even the right curve to be using?
