my code :

deleted after AC

in stuct line : 'm' & 'd' are from line equation y= m x + d
l1 : is the line that between cross1 and ball (as l2 : cross2 , ball )
far1 : is the distanse between Goal Keeper center (GKc) and l1 (as far2 : GKc , l2)

i think my wrong in output form.
thanks

Why are you trying to kick the ball into your own net?

Sorry but i'm sure it was in the opponent goal :
as we know the board center coord (0,0) so if GK x axis > 0 so opponent goal x >0 ( so 'fact' take 1) otherwise 'fact' = -1.
Cross bars of the net coords on x are 'cross(1,2).x' * fact .
if distanse between l1 (or l2 or both) and GK center > R so sure player can did it.
thanks leppy

If fact == -1, you are shooting the ball into your own net.
