Initialize page:
[code]
vy=V*Math.sin(angle);
[/code]
need to be modified to [code]vy=V*Math.sin(angle[color=red]*pi/180.[/color]);[/code]

code in "fixed relation" page
[code]
if(_isPlaying() && x>xmin+size && y<ymin+size )
[/code]
need to be modified to
[code]
if(_isPlaying() && x>xm[color=red]a[/color]x+size && y<ymin+size )
[/code]

Then, it should be fine (or check out attached file).
