pygame安装 pip install pygame
在CMD中输入python -m pygame.examples.aliens可以看到一个自带的pygame的演示小游戏
学了几天pygame，那就实践一下吧，如图实现玩家操控小鸟躲避小球的游戏，当碰撞到小球游戏结束，关闭游戏
所以我们需要实现以下几个功能：
1.操控小鸟
2.小球移动
3.碰撞检测
4.结束游戏
一. 控制小鸟我们用pygame.KEYDOWN来检测，当用户敲击下键盘上下左右时，改变鸟的位置坐标，并消除之前的图片
1 #键盘敲击事件 2 elif event.type == pygame.KEYDOWN: 3 #上 4 if event.key == pygame.K_UP: 5 if imageRect.top != 0: 6 pygame.draw.rect(screen,THECOLORS[‘white‘],imageRect) 7 imageRect = imageRect.move(0,birdspeed[0]) 8 count = count + 1 9 #下 10 elif event.key == pygame.K_DOWN: 11 if imageRect.bottom != 360: 12 pygame.draw.rect(screen, THECOLORS[‘white‘], imageRect) 13 imageRect = imageRect.move(0,birdspeed[1]) 14 count = count + 1 15 #左 16 elif event.key == pygame.K_LEFT: 17 if imageRect.left != 0: 18 pygame.draw.rect(screen, THECOLORS[‘white‘], imageRect) 19 imageRect = imageRect.move(birdspeed[3],0) 20 #右 21 elif event.key == pygame.K_RIGHT: 22 if imageRect.right != 540: 23 pygame.draw.rect(screen, THECOLORS[‘white‘], imageRect) 24 imageRect = imageRect.move(birdspeed[2],0) 25 #按ESC退出游戏 26 elif event.key == pygame.K_ESCAPE: 27 sys.exit()
二.我们先设置小球的初始位置，然后让小球从右向左移动，并用draw.rect画掉之前的图像，当小球到达屏幕最左端的时候，我们让它重新出现，并且修改纵坐标为鸟的同一行
1 replace_rect = pygame.draw.rect(screen, THECOLORS[‘white‘], ballRect) 2 #小球自右向左移动 3 if ballLocation[0] > -60: 4 if count > 10 and count < 8: 5 ballLocation[0] = ballLocation[0] + ballspeed[count//10] 6 else: 7 ballLocation[0] = ballLocation[0] + ballspeed[0] 8 else: 9 ballLocation[0] = 540 10 #小球移动到最左端时改变出现的位置 11 if ballLocation[0] == -60: 12 ballLocation[1] = imageRect.top 13 #纵坐标超出范围时修改 14 if ballLocation[1] > 359: 15 ballLocation[1] = ballLocation_change[random.randint(1,6)]
三.碰撞检测和结束
我将鸟的图像创建一个Rect对象，相当于这个rect对象帮我获取的鸟这个图像的上下左右的坐标，这样我们就可以用来判断它的位置信息，这里我用ballLocation来存储球的位置
1 #碰撞检测的实现
2 if imageRect.bottom == ballLocation[1]+60 and imageRect.top == ballLocation[1] :
3 if imageRect.left-ballLocation[0] < 60 and imageRect.left-ballLocation[0] > 0 :
4 #如果碰撞就结束游戏
5 print("Game Over")
6 pygame.mixer.music.load(gameOver_musci)
7 pygame.mixer.music.play()
8 screen.blit(game_over_image,[0,0])
9 pygame.display.update()
10 pygame.time.delay(1500)
11 sys.exit()
完整代码如下，注释还挺多的，图片和音乐资源网上自己都能找到，用自己喜欢的图片就行了，最好是透明的图片，如果和我一样图片不是透明的而是白色背景，就得加这个了不然就不用
将透明色设置为白色control_image = pygame.image.load(‘资源/img/bird.png‘).convert()control_image.convert_alpha()control_image.set_colorkey(ALPHA)
