w'cwc Let's enter the detailed tutorial below:
1. First, let’s create a folder planewars (name it randomly):
Then open this file with pycharm in our python, our aircraft war project is going on here
2. We need to use the pygame module to write this small game
Supplement: Pygame is a game library written using the SDL library, and Pygame is a library that uses it in Python.
1. Install the pygame module
The installation command is as follows: pip install pygame
We open the command line (terminal) directly in pycharm Download (I have downloaded)
You can also use (cmd) to download
Try using the pygame module when you're done
1. ⦁ First create a new py file pygameexperience.py
⦁ Then edit the following code
import pygame
pygame.init() # 初始化
print("游戏代码....")
pygame.quit() # 卸载模块，释放资源
As follows: 
You can click on the URL I marked to see pygame
3. Supplementary knowledge (use rect to describe the position of the aircraft vs. heroes)
1. Rect is a pygame object used to store the coordinates of a rectangle. The rect object has some virtual properties, such as top, left, bottom, and right, which are used to fix the position of the rectangle, and size, width, height, which describe the rectangle Size, width and height respectively.
center is the center point of the rectangle, which is actually a two-tuple about the horizontal and vertical coordinates, so there are two attributes of centerx and centery. In addition, there are x, y.
Rect construction method:
rect = pygame.Rect( left , top, width, height )
2. Create a plane_rect.py file below for demonstration
import pygame
pygame.init()
hero_rect = pygame.Rect(100, 200, 125, 300)
# 100： 表示距离x轴原点的位置
# 200： 表示距离y轴原点的位置
# 125：矩形的宽度
# 300：矩形的长度
print("英雄机矩形的x={},y={}".format(hero_rect.x, hero_rect.y))
print("英雄机矩形的宽width = {},高height = {}".format(hero_rect.width, hero_rect.height))
print("英雄机矩形的中心 centerx={}".format(hero_rect.centerx))
print("英雄机的低部 bottom={}".format(hero_rect.bottom))
print("英雄机的左部 left = {}".format(hero_rect.left))
print("英雄机的右部right = {}".format(hero_rect.right))
print("英雄机大小".format(hero_rect.size))
pygame.quit()
3. Let's create a game window and a game loop
import pygame
pygame.init()
# 1.创建游戏窗口
pygame.display.set_mode((480,650)) # 元组中480表示宽度， 650表示高度
# 游戏循环
while True:
pass
pygame.quit()
The game we wrote just adds the code in the template
operation result:
4. The pictures we will use (you can find them online directly)
(Put the picture you use in img)
4. The following is the source code of our aircraft war (see for yourself with comments)
