Welcome to the introduction to PyGame and Python 3 video game programming! Suggested Requirements for this series You may wish to be familiar with the basics of the Python 3 programming language, or at least the basics of Programming in general That said, this course begins at a slowish pace, and I do my best to explain everything at least the first time it shows up. PyGame can actually be a wonderful starting place for your journey in Python.
Game creation in any programming language is very rewarding, and also makes for a great teaching tool. With game development, you often have quite a bit of logic, mathematics, physics, artificial intelligence, and other things, all of which come together for game creation. Not only this, but the topic is games, so it can be very fun. Many times people like to visualize the programs they are creating, as it can help people to learn programming logic quickly.
Games are fantastic for this, as your are specifically programming everything you see. Installation may vary by operating system. Macs historically have had trouble with PyGame, so you may need to get an earlier version of Python and PyGame. Nowadays, pip is probably the best method for installing PyGame, since it comes with the latest versions of Python 2 and Python 3.
Then, we run pygame. This will initiate PyGame, and allow you to then make various commands with PyGame and our game. You may also see this referred to as a "surface," as this is basically our canvas that we will draw things to, and the function literally returns a pygame.
Surface object. We are saying right now that we want the resolution of our game to be px wide and px tall. Take note that this is a tuple as a function argument. If you do not make this a tuple with parenthesis, then and will be treated as separate parameters and the function will blow up. Clock Simple enough, this is a our game clock. We use this to track time within the game, and this is mostly used for FPS, or "frames per second.
Anyway, we can increase FPS to literally speed up the game, or slow them down to slow down the game. More on this later though! Then, we run our "game loop," which will run until we crash. This is going to be present in most PyGame scripts, where events are constantly being logged. It is shown in the video, but not here, but you can still try it: Try adding "print event" above the if statement. You will see in your console everything you do within the PyGame window.
Pretty neat! After our if statement. Basically the entire screen. That said, if you do not pass a parameter, then update will update the entire surface as well, bascially making flip pointless for our interests.
There might come times when you want to use flip for very specific tasks, however. The last thing within this while loop is clock. Basically, this is how many frames per second we are running. In this case, we are running 60 FPS. This will end our pygame instance. Then we can run a simple quit , which will exit Python and the application.
It has been created and tested on Linux. The PyGTK programming tutorial is suited for novice and more advanced programmers. It offers a comprehensive set of graphical elements and other useful programming facilities for creating desktop applications. PyGTK is very easy to use, it is ideal for rapid prototyping. PyGTK consists of several modules.
