Notice how when the aiming position is predicted, a line-of-sight test must

be made to ensure the predicted position is unobstructed by walls. This is

not necessary if the weapon is aimed directly at the target because the LOS

to the target position is cached when the target’s memory record is updated.

Notice also how immediately before the weapon is fired, some noise is

added to the aiming position in order to prevent the shot from hitting the

target 100 percent of the time.
