is it possible.
To make a drawing script.
where you can draw together pieces of puzzles.
like, where say. A bridge get's destroyed by the evil master, and you use the paintbrush of destiny to draw in the dotted block, a new bridge. I'm not sure if something like that is possible.
Drawing from Platforms to full out stages, even heroes or enemies and items.
You want something like in that one wii game... what was it´s name...
Hopefully somebody helps you... I stink at scripting...
Okami is the game you're thinking of.
It was actually first on the PS2, then ported to the Wii since it was so popular. (or something like that...)
This kind of script of recognizing mouse paths compared to defined images have been mentioned in the forum before...
Mmm...
*too lazy to search ;)*
Use the terms like... Lost Magic Mouse, and something should pop up...
