This article mainly shows you "Pygame how to achieve bouncing ball Mini Game", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to achieve Pygame bounce ball Mini Game" this article.

1) the rules of the game

More than the usual table tennis? More simply, the player only needs to catch the ball and hit it back, and the player who gets 10 goals first will win (can be modified).

Single operation: key up and down; double mode: one is the key up and down right, there is another is WS up and down.

2) material preparation

3) Environmental installation

The environment used in this paper: some of the Python3, Pycharm and Pygame modules are self-contained.

Pip install-I https://pypi.douban.com/simple/ + module name

Second, tap code 1) configuration file

Configuration file: background color, interface size, some background music of the interface, etc. The following code is very simple to understand.

Mm-hmm, thinking that the video does not need, this is a very simple interface, just take a screenshot and show it directly. Jpg
