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.
