Walls - notapixelstudio/starship-olympics GitHub Wiki
Instance a Wall scene into a Battlefield node to create a wall. Walls should be used whenever we need a solid area that cannot be passed through. If you want a pass-through area, use a Field instead.
A wall can be either normal or hollow. Hollow walls may only be used as containers for the whole level. Offset and elongation can be used to thicken and enlarge the outer collision shapes.
A wall can be solid (stuff bounces when colliding) or hostile (if they touch it, ships are killed and bombs are triggered).
To give the wall a shape, provide a suitable GShape node as a child and configure it.
