This is kind
of a visual graphic of what happens with this crazy quake sighting
system. It is not a "true" sight which would fire the weapon/grapple
in question almost exactly "from" the crosshairs. For instance,
if you had the crosshairs of a real rifle over a wall, the barrel
would be too, and you would fire over the wall through the sights.
As im sure you have noticed with the railgun, even if your sights
are over an edge and you are standing straight up and close to the
wall, you will shoot the wall, cause the gun fires from chest level
and "meets" the sights at infinity. This is the same for the grapple
and all the weaps in quake. But, as your model approaches the max
look up or down positions, the sight become 100% accurate. (if you
are looking all the way up or down over an edge, your sights are
As you can see
by the picture, the grapple is "shot" from the chest area and it
rises to the crosshairs at infinity. In otherwords, if you try to
shoot the grapple over an object, the closer you are the higher
you must aim. The start of the grapple would scribe an elipse about
the front of the model (see below).
not all! As the model approaches its maximum up and down positions,
the grapple alters its "shot" location. When in the max up or down
position, the grapple shoots directly from dead center of the crosshairs.
Please keep in mind that this is for center handedness. With left
and right handedness, there is also a shift in that direction. This
also applies to all weapons.
