Tkinter Details

I was working on a very simple game. When you see two shapes of the same color, you need to "snap" them. I was following a tutorial from a book to write this program. They decided to use the tkinter module for the GUI. You would think that pygame is the right tool for the job. But I guess there are many ways to code a game.

The user presses a key (such as the letter q) to to perform a snap when they see matching colors. I was trying to trap this key press event like this:

    Canvas.bind('q',my_handler_fxn)

However, my function was never getting called when I pressed the key. I was banging my head against the wall for a little while. Then I identified that you need to tell tkinter to send those key press events to the Canvas object with this simple call:

    Canvas.focus_set()

With that small details taken care of, I was off to the races playing my snap game.

I am attending college part time right now. The college gave me access to an O'Reilly digital library. It has books published by O'Reilly. But it also has a lot of other books too. It feels like an Amazon Kindle Unlimited subscription for technical books. So far, I have checked out quite a few of the books, especially those related to Python. I have stored a picture of all the covers of the good books on my local hard drive. Each book has a directory with the book name as the directory name. I have standardized on calling the book cover image "cover.jpg". Now I would like to browse all these books of interest. There are over 100 of them. So I wrote a small Python program to go through the root directory, find all the book names, and create a web page with all the covers. I standardized the size of the covers, and made them small so I could see more per page. Voila.

Memories of Logo

The turtle module in python reminds me of the old Logo programming language. I recall it as a teaching language from the 1980s. It was marketed as a simple language that kids could use to learn how to do rudimentary programming. You would give the turtle directions, and it would draw pictures on the screen for you. I am reading a book where they encourage you to write your own functions to create shapes using turtle. For example, while you could write the turtle calls out to draw a rectangle, it would be easier just to call your own rectangle() function. Sounds good to me. Right now I am doing some block style drawing. But pretty soon I am going to make some patterns like Spirograph, another item from the 1980s.

Mission Accepted

I started a new programming book today called Mission Python. The whole book is teaching you how to create a graphic adventure game. I already downloaded the finished product. While I was unimpressed by the game since I kept getting killed, I think this was because I did not understand the controls well enough. Decided to give this book a go. I was pleased that by the end of chapter 1, we have draw the planet Mars, a spaceship, and an astronaut. The astronaut can move and is controlled by the arrow keys. And when the astronaut move past the spaceship, it "goes behind" the spaceship. Pretty good for chapter 1. The only drawback is that this game requires Pygame Zero. I wish we could have done the whole thing with only Pygame. But maybe the extra module makes things a bit easier.
