All these questions lately about backgrounds, masking and templates made me think of an old promise I made my kids: to draw the bed time stories, we used to invent.
They are about 2 bored alien boys, Schlipp and Schlopp, which visit us and have adventures with my boys. All the stories have the same intro: "in a galaxy far far away..." and while telling the intro, the ideas begin to flow and you can include both funny, entertaining and "educative" themes.
As aliens, Schlipp and Schlopp have of course all sort of sophisticated stuff to travel in imaginary worlds. So there are no limits to your imagination.
So far for the introduction.
Starting point of the comic strip is the layout. A page frame sets the margins of the page.
The strips are set up by a 1-D shape, configurable from 1 to 6 tiles. The shape can be arranged horizontally or vertically. As 1-D shape it snaps neatly on the connection points of the frame.
The tiles's width is set up using control points. That helps arranging them relatively to other strip tiles.
The actors are still primitive groups. There's room for improvement.
