For the player, I implement the location as the distance from the original position to where it is now. The event-handling code in the event loop will then get the events such as key pressed or mouse click or mouse motion and then respond to the events detected. In order to accomplish this, we need to keep track of the player paddle location, ball location, and cpu paddle location. () () Calling the above functions tells us the state of the input device at the moment you call the function. The ball must bounce of the sides of the walls or the paddle (and if the ball touches the player side, log that the player lost, same for the CPU side).The CPU must automatically track the location of the ball and follow it.First we have the infinite game loop, followed by a loop returning occurring events, following by a condition check to see if any key is currently being pressed. The player must be able to move their paddle Below is a simplified piece of code from our Pygame RPG Tutorial, where we detect key presses from the user.There are a couple main mechanics of the game: However, it is key to understand how the game works. The various keyboard key and corresponding pygame keys are: pygamekey. For example, the pygame key for the letter A is Ka then we will compare event.Key with K a and if it comes to be same that means the key A was pressed. If the event is not QUIT, then it updates the display screen.īefore the loop or the game_on is where the real meat of the game is. To know which key was pressed, we have to check the event.key variable corresponds to which pygame keys.
You may check out the related API usage on the sidebar. You can vote up the ones you like or vote down the ones you dont like, and go to the original project or source file by following the links above each example. There are two types of key events in pygame: KEYDOWN and KEYUP. These examples are extracted from open source projects. pump() every game loop to make pygame process the events internally.

What this does is it loops through each event in the current events, and checks if one of the events is a QUIT event (ie the user somehow tries to close the window). The following are 30 code examples for showing how to use pygame.KEYUP ().
