1.pygame加载图片

import  sys, pygame

pygame.init()

screen = pygame.display.set_mode((500, 500))

ball = pygame.image.load("intro_ball.gif")
red = pygame.Color(255, 0, 0)
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    #画线
    pygame.draw.line(screen, red, (10, 10), (200, 200),  10)
    #画矩形 pygame.draw.rect(screen,red,(10,20,200,300),10)#坐标加长宽
    #画圆 pygame.draw.circle(screen,red,(100,100),50,5)
    #图片的绘制
    screen.blit(ball, (100, 100))
    pygame.display.flip()

2.pygame加载字体和音乐

import pygame, sys

pygame.init()
screen = pygame.display.set_mode((500, 500))


red = pygame.Color(255, 0, 0)
#字体，从系统中获取字体，必须是存在的
# font = pygame.font.SysFont('华文新魏', 40, False, False)# 是否粗体,斜体
#从字体文件中加载字体
font=pygame.font.Font('./STXINWEI.TTF',40)
#文字对象渲染
text = font.render('得分', True, red)


#加载音乐
bg_music = pygame.mixer.music.load("neverM.mp3")
pygame.mixer.music.set_volume(0.2)#0~1，值越小音量越小
pygame.mixer.music.play(-1)#-1,循环播放背景音乐
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
    #设置字体位置
    screen.blit(text, (20, 20))
    #更新
    pygame.display.flip()

3.pygame实现图片帧率切换

import pygame, sys

pygame.init()

screen = pygame.display.set_mode((500, 500))
image = pygame.image.load('hero1.png')
image2 = pygame.image.load('hero2.png')

clock = pygame.time.Clock()
counter = 0
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()

    #利用帧速率进行图片切换控制，一秒钟60帧
    clock.tick(60)

    #屏幕绘制白色背景
    screen.fill(pygame.Color(255, 255, 255))
    if counter % 5 == 0:
        screen.blit(image, (20, 20))
    #绘制图片
    else:
        screen.blit(image2, (20, 20))
    pygame.display.flip()
    counter+=1

碰撞检测

import sys, pygame
pygame.init()

size = width, height = 320, 240
print(type(size))
speed = [2, 2]
black = 0, 0, 0

#得到屏幕对象
screen = pygame.display.set_mode((320, 240))

class Block(pygame.sprite.Sprite):

    # Constructor. Pass in the color of the block,
    # and its x and y position
    def __init__(self, color, width, height,init_pos):
        # Call the parent class (Sprite) constructor
        pygame.sprite.Sprite.__init__(self)

        # Create an image of the block, and fill it with a color.
        # This could also be an image loaded from the disk.
        self.image = pygame.Surface([width, height])
        self.image.fill(color)

        # Fetch the rectangle object that has the dimensions of the image
        # Update the position of this object by setting the values of rect.x and rect.y
        self.rect = self.image.get_rect()
        self.rect.topleft=init_pos
screen = pygame.display.set_mode(size)

#实例化精灵对象
sprite_1 = Block(pygame.Color(255, 0, 0), 50, 50, (50, 50))
sprite_2 = Block(pygame.Color(0, 255, 0), 50, 50, (150, 150))


while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: sys.exit()

    #向屏幕上加载精灵
    screen.blit(sprite_1.image, sprite_1.rect)
    screen.blit(sprite_2.image, sprite_2.rect)
    #矩形检测碰撞
    rest = pygame.sprite.collide_rect(sprite_1, sprite_2)
    print("rest", rest)
    #指定可碰区域的大小
    rest2 = pygame.sprite.collide_rect_ratio(1)(sprite_1, sprite_2)
    print(rest2)
    pygame.display.flip()
