This event-handling code then continuously monitors the user’s inputs and responds to the events, as they occur. Responding to the events is done by adding event-handling code to the main loop ( event loop). Responding to an Event is referred to as Event Handling.
When Events occur, the program needs to be able to respond to them and take appropriate action. Now we will see how events are used in Pygame Graphical Programming.įor more information on Pygame events refer to the link below: We learned about Events as used with the Tkinter Graphics Programming chapter. Events are the user actions that occur in a program such as: Reacting to events is required for all applications and interactive games. The essential part of any interactive application is the event loop. Making the object respond to user actions makes the app interactive. The program will move the ball in response to the Events such as key presses, mouse movements, or mouse clicks. The applications in the next few sections will move the ball we displayed in the previous application.
Now, we will create an app to move that image. We wrote programs to display the image of an object on the previous pages. The events make the app interactive, meaning that our game or app responds to user inputs from the keyboard and mouse. The player can interact with the program’s graphical objects through mouse clicks or key presses.
