Your game will need to include assets such as images for sprites, backgrounds and other things in your gamefonts so you can write text to atomic aquatics screen in your gamesounds for sound effects to signal when something has happened in your game and music to create an atmosphere for your game. Using a different variable name helped give him ownership of the code he wrote. Nicholas is also largely responsible for the Mu editor. We had conversations about how he would have to use his slimearm name instead of what he was seeing from hellstorm documentation page.|

This book contains all the example programs used in my CoderDojo class to teach Python programming.|
We can read the state of these keys inside another predefined function called update. We need to write some code to detect key presses of arrow keys and also to do something about it. We are going to build our track out of Actors, one row at a time. We will need to make some lists to keep track of the Actors we create.
Then let's make a new function called makeTrack , The function will add one track Actor on the left and one the right, both using the image bare. The next thing that we need to do is to move the sections of track down the screen towards the car. The track pieces are created by random numbers so each play is different. If we run our code at the moment, we should see a track snaking down towards the car. The only problem is that we can move the car over the track barriers and we want to keep the car inside them with some collision detection.
In this game we will have three different states to the game stored in our variable gameStatus :. We will need to change our draw function and our update function to respond to the gameStatus variable. All we need to do now is to display something if gameStatus is set to 1 or 2, for example we should display a red.
To see if the car has reached the finish, we should count how many track sections have been created and then perhaps when we get to , set gameStatus to 2. Then display the chequered flag :. On Raspberry Pi pgzero has been installed by default since the release of Raspbian Jessie in September You can make the game easier or harder by changing the trackWidth variable to make the track a different width.

More by the author:. More About Ahmed Nouira ». In this tutorial we 'll be writing a simple racing game. The Pygame module adds many functions that help you to write games in Python. Installing pip for Python 3 Start by updating the package list using the following command: sudo apt update Use the following command to install pip for Python 3: sudo apt install python3-pip verify the installation by checking the pip version: pip3 --version Installing Pygame Zero pip3 install pgzero --user This will also install Pygame.
Pygame zero provides predefined functions to handle the game loop normally performs : The draw Function We can write this function into our program the same as we would normally define a function in Python. Then open a Terminal window, go to your file location and type :. You can set its position on the screen by typing : car. Once we have our car drawing on the screen, the next stage is to enable the player to move it.
The update Function This function is continually checked while the game is running. So we will add this function to our program def update : if keyboard. Here are some highlights:. Pygame Zero is a tool for making video games. The differences between Pygame Zero and Pygame are related to the target audience. I think the Pygame Zero documentation states their project goal well:.
I mentioned at the start of this article that I was learning how to write games too. In my personal exploration of game development, Pygame was my primary choice for writing games. When I view Pygame today, it seems more like a game library than a game engine. All the pieces are in place to make a game, but you have to wire everything together yourself. And it would border on impossible for a six year old kid. When I tried out Pygame Zero, I was surprised how different the experience was.
Pygame Zero is much more like a game engine. The common pieces that you must handle yourself in Pygame are pre-wired in Pygame Zero. This dramatically lowers the barrier to entry, at the cost of flexibility. After all that research, we made our first game in Pygame Zero. His entire game fits into 29 lines of code, including blank lines. In this 29 lines of code, he was able to learn an enormous amount of stuff.
Also, to give credit where it is due, the game is a modified version of the one listed in the Pygame Zero introduction. If your eyes are hurting, you can thank my son for the hot pink color choice. The documentation used black, which might be a better fit for outer space. I explained how variables are names for something else and how the name could be whatever we wanted. Because our program took many weekends to complete, we revisited the variables concept each time.
Ultimately, I found that the best way to show how little the names mattered was to suggest we change the name alien in the documentation to something else. Thus, slimearm , his choice, was born. Using a different variable name helped give him ownership of the code he wrote. We had conversations about how he would have to use his slimearm name instead of what he was seeing from the documentation page. My son would:.
Now that I think about it, kids would make for amazing Quality Assurance engineers given their pension to explore and try things out. Our industry has an odd obsession with thinking about side effects. Entire modes of programming try extremely hard to minimize side effects. Games are really neat because they embrace side effects fully. Since the side effects show us that our code is doing things, they bring a lot of satisfaction. When I got to the draw function, my son got what he came to see: the computer doing something that he wrote!
These were the side effects in action. This draw function has no return statement. Each time you call it, the results will be different because of the state of slimearm. When we first started draw , we dealt with screen. Before we could see the effects of slimearm.
When I reached this stage, I had to find a method to explain how Pygame Zero alternates between draw and update to make the game run. I used the idea of a filmstrip to illustrate the concept. We are well into the digital age for most video production so film is a rarity.
After I explained how film worked, my son latched onto the idea of frames as individual images that are drawn on the screen. We talked about how update is in between the frames and causing the frames to be different from each other.
He seemed to understand the idea, but then we had to explore coordinates and x, y pairs and more concepts from Algebra that he has not studied yet! So, I went back to the drawing board, literally. The best way I could think to explain how things worked in a 2D coordinate space was with a paper prototype. Our paper prototype was an extremely useful visual tool. With the prototype, I made a game window and our alien character which I labeled as slimearm to match the variable name.
Using the two separate pieces of paper, my son could see, in a very visual way, how the character would move. By anchoring on the filmstrip concept, we iterated through the game loop each frame. Since he could point to the various parts, like the left edge which advanced in the update method, he was able to understand how the computer changed the position of the alien. The labels also helped him get a grasp on the conditional logic.
The point of this game is to try and click the alien. We started with the concept of events. Being a digital native, my son had no trouble with thinking about actions like touching a screen. Our first version of the function above looked more like this:.
Even this simple level of interaction was enough to make my son light up. It turns out that low tech feedback is enough to get kids really excited! When we moved up to the full function, I had to explain collisions. Thankfully, the paper prototype made this easy because we could make a game out of the game. I told my son to pretend to play the game while I was the computer. Not only did this make us both smile, but the idea of colliding was really natural because of the real world analogue.
The trickiest part of this was to explain computer clocks and the purpose of the line:. Frankly, we had nearly everything working so his interest in adding more code waned rapidly. You need to understand that functions are things that can be passed around like variables. Some of the lessons were reminders of things I knew, but some of these were new lessons.
And one more time: repetition. We need to experience things repeatedly for the concepts to sink in.
