The beam is drawn on top of an ordinary shot rather than in place of one: the projectile is still created, still travels and still detonates, and the damage is entirely the projectile’s. What the flag adds is two pieces of scenery drawn between the muzzle and the target’s own aim point.

IsLaser=yes
LaserInnerColor=255,0,0

Projectile=LLine ; a BulletType, registered by a weapon naming it as its Projectile

The first piece is the beam itself: a thin line in LaserInnerColor, flanked by a pair of glow lines in LaserOuterColor jittered each frame by LaserOuterSpread, lasting LaserDuration frames. The second is a screen glow spanning the same line, which brightens only the red of whatever lies beneath it whatever colors the beam was given; IsBigLaser=yes widens it.

A weapon with a barrel normally has its shot stepped forward the moment it is created so that it appears past the muzzle rather than inside it. A laser weapon skips that step, so its projectile starts at the barrel mounting. On a structure the beam also stops the turret animation dead and resets it to its first frame, which is how a Charges=yes turret drops out of its wind-up pose.
