title: Finding control points for bezier curve
body: <p>Hi stackoverflow's users ! </p>
  
  <p>First i want to say its my first post and i've been diging straight up gold from this site and i love it and everyone out there smart enough to give out solutions.</p>
  
  <p>So basically am writing a game and i have bezier curve that controls where an actor moves. Am using only 3 points (start, control1, end) and everything is fine.</p>
  
  <p>Now i want to create a bezier curve that passes through a certain point (r1) at t = 0.5 . The problem being that i have my start point, my end point and my point (r1) at t=0.5, and i need to find the control point.</p>
  
  <p>Sorry if i explained it badly i hope everyone can understand.</p>
  
  <p>Thank you for any replies : )</p>
