Let's write a script to experiment with the keyboard.

For example, if we were using the spacebar as a fire button, we might write the trigger code like this: To look up a particular key, use its constant as an index into the pressed list. It returns a list of booleans (True or False values), one for each of the key constants. We can use the _pressed function to detect whether a key is pressed. If you need to detect capital letters, or other Shifted keys, use the unicode parameter in key events that contain the result of such key combinations. The reason for this is that capital letters are the result of combining keys together (Shift key). See the Pygame documentation for a complete list ( Since there are constants for K_a to K_z, you may expect there to be equivalent uppercase versions-but there aren't any. There are letters (K_a to K_z), numbers (K_0 to K_9), and many other constants such as K_f1, K_LEFT, and K_RETURN. In this case, we can use the pygame.key module more directly.Įvery key on the keyboard has a key constant associated with it, which is a value we can use to identify the key in code. But when we use keyboard input for movement, we simply need to know if the key is pressed or not before we draw the next frame. Events will also capture very quick taps of the key for fire buttons. This is great for typing text because we will always get keyboard events even if a key has been pressed and released in the time since the last frame.
One way is to handle KEYDOWN events, which are issued when a key is pressed, and KEYUP events, which are issued when the key is released. There are two ways to detect a key press in Pygame.
