*** Not a complete project *** This demonstrates another method of doing string art patterns (similar to my projects String Art and Son of String Art). The method used here uses very little math and very few variables. Instead, it uses a small group of sprites to keep track of the control points and to draw the fill lines. A more Scratch-like approach, but a bit slower. How this works: As the stage is clicked, the sprites Dot 1 through Dot 3 are sent to the mouse click locations. Once the third dot is in place, it sends a message to the Traveler sprites (Traveler 1 and Traveler 2). The Traveler sprites will mark the endpoints of the fill lines that will be drawn. Traveler 1 starts at Dot 1 and moves towards Dot 2 while Traveler 2 starts at Dot 2 and moves towards Dot 3. The travelers compute a step size that will chop the distance up into the desired number of divisions. Then, Traveler 1 takes control and starts moving towards Dot 2, one step at a time. After every step, it sends a message to Traveler 2 to tell it to move a step as well. A message is then sent to the Pen sprite telling it to draw a line from Traverl 1 to Traverl 2. After the pattern is done, Dots 1 and 2 are moved up so that Dot 1 now sits where Dot 2 was and Dot 2 now sits on Dot 3. The count of dots positioned is decreased back to 2; this sets up for the next mouse click defining a new location for Dot 3 which will continue the pattern with another fill. I was inspired to try this math-free approach after looking through the scripts of fbrd's wonderful 'Curve Art 3' project.
