Today, I planned to finish the undo functionality, add instructions, and to reduce memory leaks. I was able to accomplish all this and more. I finished the undo button much more rapidly than I had hoped and reduced some of the memory problems at the same time. I then created the instructions view. I soon discovered that the instructions cannot all be displayed on the same page, and so I modified the view controller for the instructions to handle multiple pages. During this process, I discovered a much simpler way to add and remove views than I had been using previously. I also fixed a major error present in the game view in regard to promoting a diamond to a mixed "power" piece.
Finally, I met with Mr. Collias in order to discuss final changes. He taught me methods of assessing the usability of a user interface and then provided several suggestions about my project's interface and about the gameplay element.
I followed almost all of these suggestions with minor adjustments and now have the following images to demonstrate my progress:
(note the red X on the piece surrounded by diamonds and the dot in the center of the X indicating the final destination of the jump.)
Mr. Collias noted that the score display was confusing and that the execute move button was unclear. Also, it was previously difficult to determine what pieces were removed by a CINGO move and what the destination of a given move is. All of these problems have now been addressed. Note that I also added a question mark icon to the game view that, when pressed, discloses information about how to use the controls.
Tomorrow, I will attempt to finish the "Change Appearance" and "New Game..." views and to begin working on saving the state of the application on view switch/exit.
Quick Update (11:32):
Just added a picker with some randomly named components.
