Challenge: The trouble with scribbles
(upbeat music) - While we've made the user interface as nice as possible for our users, the scribe in Canvas classes are still pretty fragile and very forgiving of things like bad user input. For instance, what if a user tries to make a scribe a color that we can't handle? What if the mark or trail they enter is a very long string? What if they enter some random, non-numeric garbage for the frame rate or the degrees? Also, despite our best and most careful programming, there may be situations we hadn't encountered, resulting in something being written out of the bounds of the canvas and sending the program crashing into a fiery blaze.
