Hi! Can anyone provide a working example of LinePick? I am setting EntityPickMode, etc. but it always returns 0. Thanks!

here it works result=linepick(x,y,z,x2-x,y2-y,z2-2,0.1) where x,y,z is the start position and x2,y2,z2 is the end position of the pick. Or use w,h,d instead of x-x2 etc. Isn't there an example in the docs? You can also check if things are working correctly, when you use Camerapick with mouseX/Y. Example: cube=createcube() entitypickmode cube,2 p=linepick(0,0,-10,0,0,20,.1) print p waitkey()

Thanks. There is no example anywhere in the Documents, Samples or Tutorials (including the second set). Your example works (in isolation) but I still get nothing but zero's back when using LinePick in the context of an FPS. Wish I knew why!
