This article mainly shows you "how to use Python to create games", the content is easy to understand, clear, hope to help you solve doubts, the following let the editor lead you to study and learn "how to use Python to create games" this article.

Using Pygame for game development

Pygame is an open source Python module dedicated to the development of multimedia applications such as video games, including support for images, sounds, videos, events, collisions, and so on. Pygame is based on SDL. SDL is a cross-platform multimedia development library implemented in C language and is widely used in the development of games, simulators, players and so on. On the other hand, Pygame makes game developers no longer bound by the underlying language and can pay more attention to the function and logic of the game.

Load Ima

If you need to load the image directly into the window, you can use the function of the image module in pygame to load the image, and then render the image through the blit method of the window object obtained previously

Realize the animation effect

When it comes to the word animation, we are no stranger. In fact, to achieve animation effect, the principle itself is very simple, that is, the discontinuous pictures will be played continuously, as long as a certain number of frames per second is reached. Then you can make a relatively smooth animation effect. If you want the ball in the above code to move, you can use a variable to represent the position of the ball, and modify the position of the ball in the loop and then refresh the entire window.

Collision detection

Usually there are a lot of objects in a game, and the "collision" between these objects is inevitable, such as shells hitting the plane, boxes hitting the ground and so on. Collision detection is a crucial issue that must be dealt with in the vast majority of games. Pygame's sprite module provides support for collision detection. Here we do not introduce the functions provided by the sprite module for the time being, because to detect whether two balls collide or not is actually very simple, just check whether the distance between the center of the ball is less than the sum of the radii of the two balls. In order to create more balls, we can create balls with random color, size and moving speed at the location where the mouse is clicked by handling mouse events. we can apply the object-oriented knowledge we have learned before.

Event handling

Mouse events can be handled in the event loop, the event type can be determined by the type property of the event object, and then the mouse click location can be obtained through the pos attribute. If you want to handle keyboard events in this place, it is similar to dealing with mouse events.
