If set, the game will draw a colored wave along the projectile path (target -> firer when targeting VehicleTypes, reversed otherwise). This is used on the Magnetron. A similar, but broken wave can be created by using IsSonic=yes on the weapon instead.
Note: if the projectile is invisible, then the warhead will detonate when the wave hits the target. If it is visible, this wave will be only a graphic effect, and the warhead will detonate when the visible projectile hits. However, AI units will "sense" the wave and try to scatter before the projectile hits.
If the target moves out of Weapon's Range, the MagBeam will still be drawn and AmbientDamage will still work.
