pygmae游戏开发——像素鸟（flappy_bird）

一、框架建立：

1.导入模块：

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

在下方package处搜索添加模块

2.环境变量加载：

PAC_DIR = os.getcwd()        #获得当前文件所在项目文件目录
sys.path.append(PAC_DIR)
 

3.配置变量（方便修改参数）
#menu:
COLOR=(255,255,255)#背景颜色白
SIZE = WIDTH,HEIGHT=336,600#视窗宽高
#bird:
BIRD_SIZE = BIRD_WIDTH,BIRD_HEIGHT=34,24#bird宽高
GRAVITY=5#模拟重力
GRAVITY_ACCESS=0.4#模拟重力加速度
BIRD_ACCESS=1.5#模拟上升阻力
FLY_SPEED=15#上升速度
VOLPLANING=1#滑翔时的降落速度
#pipe:
PIPE_SIZE=PIPE_WIDTH,PIPE_HEIGHT=54,640#管道宽高
PIPE_SPEED=3管道移动速度模拟飞行

4.模块加载
pygame.init()#pygame初始化

screen= pygame.display.set_mode(SIZE)#创建视窗
clock=pygame.time.Clock()#设置时钟实例

5.自定义函数
def menu_load():#调用blit功能显示所创建图片等初始化条件

"""

pygame.blit(类中加载对象,图片显示的位置（右上角为位置点位，元组）)

"""
    clock.tick(30)  # 帧率
    screen.fill(COLOR)#刷新背景色
    screen.blit(background, (0, 0))#刷新背景位置
    screen.blit(bird.bird_status[bird.state], (bird.birdx, bird.birdy))#刷新bird图片加载对象与位置
    screen.blit(pipe.pipe,(pipe.pipex,pipe.rand_Y))#刷新pipeU图片加载对象与位置
    screen.blit(pipe.pipe,(pipe.pipex,pipe.rand_Y+pipe.blank+PIPE_HEIGHT))

#刷新pipeD图片加载对象与位置

    menu.goal_print()#分数打印
    if bird.death:
        screen.blit(menu.goal,(0,HEIGHT/2))
    else :
        screen.blit(menu.goal, (0,0 ))
def collision_check():#碰撞检测
    U_rect = pygame.Rect(pipe.pipex, pipe.rand_Y, PIPE_WIDTH, PIPE_HEIGHT)
    D_rect = pygame.Rect(pipe.pipex, pipe.rand_Y + pipe.blank + PIPE_HEIGHT, PIPE_WIDTH, PIPE_HEIGHT)
    bird_rect=pygame.Rect(bird.birdx,bird.birdy,BIRD_WIDTH,BIRD_HEIGHT)
    if bird_rect.colliderect(U_rect) or bird_rect.colliderect(D_rect):
        bird.death=True
        pipe.speed=0

6.类定义：

bird

pipe

menu

7.程序主循环：

if __name__ == "__main__":
    while True :

        menu_load()
        #退出命令接收：
        for event in pygame.event.get():
            if event.type==pygame.QUIT:
                sys.exit()

       

        bird.bird_fly_check()#bird状态检测反馈与位置更新
        #pipe位置变化：
        pipe.pipe_update()#pipe位置刷新
        collision_check()#管道类与飞行鸟类碰撞检测

        pygame.display.update()#屏幕更新
