The first two lines are for context (you already have them in your code, if you've been following along), so add only the last three: def _init_(self): If you are animating your sprite, or should you decide to animate it in the future, you also must track frames so the walk cycle stays on track.Ĭreate these variables in the Player class. When your sprite is not moving, this variable is set to 0. To make your sprite move, you must create a property for your sprite that represents movement. Now it's time to do the hard work of making the sprite move. This confirms that Pygame detects your key presses correctly.

Launch your game using Python, and watch the console window for output when you press the right, left, and up arrows, or the A, D, and W keys. Giving your users choices, such as the option to use either arrow keys or WASD (it's called accessibility), is a sign of a good programmer. More importantly, if you seek out a job writing code for money, you are expected to write code that works for everyone. If you write code that works only for you, it's very likely that you'll be the only one who uses your application. Note: It's vital that you consider all of your users when programming. Some people prefer to control player characters with the keyboard characters W, A, S, and D, and others prefer to use arrow keys. If event.key = pygame.K_UP or event.key = ord('w'): If event.key = pygame.K_RIGHT or event.key = ord('d'): If event.key = pygame.K_LEFT or event.key = ord('a'): There's no code to make anything happen yet, so use print statements to signal success. To make Python monitor for incoming key presses, add this code to the main loop. If you answered 'in the main loop,' you're correct! Remember that unless code is in a loop, it runs (at most) only once-and it may not run at all if it's hidden away in a class or function that never gets used. Can you figure out where to put code that needs to run constantly for the duration of the game? Open your Python game script in IDLE, P圜harm, or a text editor.īecause the game must constantly 'listen' for keyboard events, you'll be writing code that needs to run continuously. Setting up keys for controlling your player sprite Start with the easy part: setting up the controller keys. However, getting your character to move is a little more complex. You created a key to quit your game in the second article in this series, and the principle is the same for movement.
