Hitscan returns the values of what would be hit if one travelled in a straight line from a set of coordinates in a specified direction.
All parameters are gamevars. The first three are the coordinates from which the hitscan occurs, followed by the scanning sector. The cos, then the sin of an angle (typically the ang of the actor performing the scan) come next, followed by the z angle, which must be calculated before the hitscan. The six return gamevars hold the values of what the hitscan hits. The value of clipmask tells hitscan which sorts of things it can hit. A clipmask of 4294901808 is useful for most purposes.
