Pygame is a python module designed to develop games. In fact, pygame is the same as time, OS, and SYS. Today, I officially started learning pygame: www.pygame.org. After the download, the installation is complete. In pygame's learning, I used the SPE editor, and it feels good.
1. pygame window
Before creating a graph in pygame, you must create a window.CodeIs it very easy.
ImportPygame # You don't need to comment on this sentence, huh, pygame. INIT ()#Module initialization,Any pygameProgramYou must execute this sentence.
Screencaption= Pygame. display. set_caption ('Hello World') # Define the title of the window as 'Hello world'
Screen= Pygame. display. set_mode ([640,480]) # Define a window size of 640*480
Screen. Fill ([255,255,255]) # Fill the window with white
2. Exit the window
Pygame has an event loop that constantly checks what users are doing. In the event loop, how to interrupt the loop (the plug-in on the right side of the window formed by pygame does not work before it is undefined), the Common Code is as follows:
WhileTrue:ForEventInPygame. event. Get ():IfEvent. type =Pygame. Quit: SYS. Exit ()
3. colors in pygame
InScreen. Fill ([255,255,255]) in this statement, we can see that pygame uses the RGB system. [0,255, 0] for pure green, [255,] for pure blue, [, 0] for pure red. If you do not use the RGB notation, pygame also provides a named color list, or you can directly use these named colors. There are more than 600 defined color sentences. You can view the specific names in the colordict. py file. When using the name list, you must first import thecolors at the beginning of the program.
FromPygame. ColorImportThecolors
Then use a named color:
Pygame. Draw. Circle (screen, thecolors ["Red"], [100,100], 30, 0)
4. Circle
Pygame. Draw. Circle () is used to draw a circle. It consists of five parameters: (1) the surface of the circle. In this example, a window is created with screen, so it is painted on the screen surface. (2) The color used for painting, for example, red [, 0]. (3) Where to draw, [top, left]. (4) diameter. (5) The line width. 0 indicates completion of filling.
Pygame. Draw. Circle (screen, [100,100, 0)
5. rectangle
Pygame. Draw. rect () is used to create a rectangle. Rect (left, top, width, height) is used to define the position and width and height. The Code is as follows:
Pygame. Draw. rect (screen, [250,150,300,200, 0], [], 0)
You can also use the following definition method
Rect_list = [250,150,300,200] Pygame. Draw. rect (screen ,[255, 0, 0], rect_list, 0)
Or
My_rect = pygame. rect (250,150,300,200) Pygame. Draw. rect (screen ,[255, 0, 0], my_rect, 0)
6. Instances
The random module is used to randomly generate sizes and positions for painting on the surface. The specific code is as follows:
# @ Xiaowuyi http://www.cnblogs.com/xiaowuyi Import Pygame, sys Import Time Import Randompygame. INIT () screencaption = Pygame. display. set_caption ( ' Hello World ' ) Screen = Pygame. display. set_mode ([640,480 ]) Screen. Fill ([ 255,255,255 ]) For I In Range (10 ): Zhijing = Random. randint (0,100 ) Width = Random. randint (0,255 ) Height = Random. randint (0,100 ) Top = Random. randint (0,400 ) Left = Random. randint (0,500 ) Pygame. Draw. Circle (screen, [0, 0], [top, left], zhijing, 1 ) Pygame. Draw. rect (screen ,[ 255, 0, 0], [left, top, width, height], 3) Pygame. display. Flip () While True: For Event In Pygame. event. Get (): If Event. type = Pygame. Quit: SYS. Exit ()
