title: Find a point along an angled line
body: <p>I'm trying to figure out how to find a point along a line (half way, to be precice). </p>
  
  <p>I need this to put a particle emitter in the correct location to leave a smoke-trail after bullets. </p>
  
  <p>I've got point A and point C. Point A is the barrel-muzzle, and point C is found using ray-cast. Now, in order to put the emitter in the right location I need to find point D. How do one do this? I attached a picure to make it more visual.</p>
  
  <p>No, I could not attach the picture, but here's a link.</p>
