Pygame简单应用(1)

  前几天趁着空闲一点，MyEclpse又跑的慢，懒的开，就开始琢磨Python了。简单的学习了一下Pygame。仿照着例子编了点代码。

  这段代码的功能就是控制绿的方块去碰撞白色的方块，撞到一起的时候，白色方块会消失，绿色方块会变大，继而在另外一个随机的地方出现一个白色的方 块，等于贪吃蛇的雏形了。如果再加上点复杂逻辑，不是让绿色方块简单的变大，而是形成一个方块的列表，在方块的“头”移动时，判断方向，可以转弯，就可以 实现贪吃蛇的效果了。

 

附上代码：

import pygame,sys,random
from pygame.locals import *

pygame.init()
mainClock = pygame.time.Clock()

# set up the window
WINDOWWIDTH = 400
WINDOWHEIGHT = 400
windowSurface = pygame.display.set_mode((WINDOWWIDTH,WINDOWHEIGHT),0,32)
pygame.display.set_caption('Test')

# set up the colors
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)
WHITE = (255, 255, 255)

# set up movement variables
moveLeft = False
moveRight = False
moveUp = False
moveDown = False

MOVESPEED = 5

# set up the nake and food data structure
FOODSIZE = 15
player = pygame.Rect(300, 100, 15, 15)
food = pygame.Rect(random.randint(0, WINDOWWIDTH - FOODSIZE), random.randint(0, WINDOWHEIGHT - FOODSIZE), FOODSIZE, FOODSIZE)



while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            # change the keyboard variables             
            if event.key == K_LEFT or event.key == ord('a'):
                moveRight = False
                moveLeft = True
            if event.key == K_RIGHT or event.key == ord('d'):
                moveLeft = False
                moveRight = True
            if event.key == K_UP or event.key == ord('w'):
                moveDown = False
                moveUp = True
            if event.key == K_DOWN or event.key == ord('s'):
                moveUp = False
                moveDown = True
        
        if event.type == KEYUP:
            if event.key == K_ESCAPE:
                pygame.quit()
                sys.exit()
            if event.key == K_LEFT or event.key == ord('a'):
                moveLeft = False
            if event.key == K_RIGHT or event.key == ord('d'):
                moveRight = False
            if event.key == K_UP or event.key == ord('w'):
                moveUp = False
            if event.key == K_DOWN or event.key == ord('s'):
                moveDown = False

    # move the player
    if moveDown and player.bottom < WINDOWHEIGHT:
        player.top += MOVESPEED
    if moveUp and player.top > 0:
        player.top -= MOVESPEED
    if moveLeft and player.left > 0:
        player.left -= MOVESPEED
    if moveRight and player.right < WINDOWWIDTH:
        player.right += MOVESPEED

    # draw the black background onto the surface
    windowSurface.fill(BLACK)
    
    
    
    # check if the player has intersected with any food squares.
    if player.colliderect(food):
        temp = food
        food = pygame.Rect(random.randint(0, WINDOWWIDTH - FOODSIZE), random.randint(0, WINDOWHEIGHT - FOODSIZE), FOODSIZE, FOODSIZE)
        while temp==food:
           food = pygame.Rect(random.randint(0, WINDOWWIDTH - FOODSIZE), random.randint(0, WINDOWHEIGHT - FOODSIZE), FOODSIZE, FOODSIZE) 
        player.height = player.height+15    
    # draw the player onto the surface
    pygame.draw.rect(windowSurface, GREEN, player)
    pygame.draw.rect(windowSurface, WHITE, food)
    
    pygame.display.update()
    mainClock.tick(50)

 

效果图见附件，一个是初始时的，一个是吃了几个白色方块后的。
