Tanks and bosses with helicopter look more realistic if there would be an option to set autoscroll which also add one ground type to a course where player and enemies keep a position where they should be without moving and where moving back happens only on solid grounds placed manually, decorations, items and for air type enemies that work with arrows. This is nothing new and exists also in Mario Forever and its best editors. One ground type can be selected where a player can stand and solid objects are moving only. This special autoscroll should also not move a background or in a real move it in opposite direction to a view traveling and should stop moving when view travel stop moving.
The ground is not moving. An editor will add one of ground from an editor.
