Description

When the game transitions to and from an Ion Storm, a short radio static animation (static.shp, I presume) is drawn tiled over the tactical view. This animation is independent from any map objects. If this feature can be expanded, it could be used to, for example, efficiently simulate rain or snowfall.

Proposed Code (optional)

Tactical view animations could be triggered via various means, be it game objects (weapons? anims?) or map triggers. New INI keys or trigger action types would be required, ones that allow specifying what (anim type), where (coords), and how to draw the animation (fixed or tiled).
