游戏时间：Skier
首先安装pygame，直接在cmd命令控制框里键入pip install pygame就可以了
代码：
import pygame, sys, randomskier_image = ["skier_down.png", "skier_right1.png", "skier_right2.png", "skier_left2.png", "skier_left1.png"]class SkierClass(pygame.sprite.Sprite): def __init__(self): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("skier_down.png") self.rect = self.image.get_rect() self.rect.center = [320, 100] self.angle = 0 def turn(self, direction): self.angle = self.angle + direction if self.angle < -2: self.angle = -2 if self.angle > 2: self.angle = 2 center = self.rect.center self.image = pygame.image.load(skier_image[self.angle]) self.rect = self.image.get_rect() self.rect.center = center speed = [self.angle, 6 - abs(self.angle) * 2] return speed def move(self, speed): self.rect.centerx = self.rect.centerx + speed[0] if self.rect.centerx < 20: self.rect.centerx = 20 if self.rect.centerx > 620: self.rect.centerx = 620class ObstacleClass(pygame.sprite.Sprite): def __init__(self, image_file, location, type): pygame.sprite.Sprite.__init__(self) self.image_file = image_file self.image = pygame.image.load(image_file) self.location = location self.rect = self.image.get_rect() self.rect.center = location self.type = type self.passed = False def scroll(self, t_ptr): self.rect.centery = self.location[1] - t_ptrdef create_map(start, end): obstacles = pygame.sprite.Group() locations = [] gates = pygame.sprite.Group() for i in range(10): row = random.randint(start, end) col = random.randint(0, 9) location = [col * 64 + 20, row * 64 + 20] if not (location in locations): locations.append(location) type = random.choice(["tree", "flag"]) if type == "tree": img = "skier_tree.png" elif type == "flag": img = "skier_flag.png" obstacle = ObstacleClass(img, location, type) obstacles.add(obstacle) return obstaclesdef animate(): screen.fill([255, 255, 255]) pygame.display.update(obstacles.draw(screen)) screen.blit(skier.image, skier.rect) screen.blit(score_text, [10, 10]) pygame.display.flip()def updateObstacleGroup(map0, map1): obstacles = pygame.sprite.Group() for ob in map0: obstacles.add(ob) for ob in map1: obstacles.add(ob) return obstaclespygame.init()screen = pygame.display.set_mode([640,640])clock = pygame.time.Clock()skier = SkierClass()speed = [0, 6]map_position = 0points = 0map0 = create_map(20, 29)map1 = create_map(10, 19)activeMap = 0obstacles = updateObstacleGroup(map0, map1)font = pygame.font.SysFont('arial', 50)while True: clock.tick(30) for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_LEFT: speed = skier.turn(-1) elif event.key == pygame.K_RIGHT: speed = skier.turn(1) skier.move(speed) map_position += speed[1] if map_position >=640 and activeMap == 0: activeMap = 1 map0 = create_map(20, 29) obstacles = updateObstacleGroup(map0, map1) if map_position >=1280 and activeMap == 1: activeMap = 0 for ob in map0: ob.location[1] = ob.location[1] - 1280 map_position = map_position -1280 map1 = create_map(10, 19) obstacles = updateObstacleGroup(map0, map1) for obstacle in obstacles: obstacle.scroll(map_position) hit = pygame.sprite.spritecollide(skier, obstacles, False) if hit: if hit[0].type == "tree" and not hit[0].passed: points = points - 100 skier.image = pygame.image.load("skier_crash.png") animate() pygame.time.delay(1000) skier.image = pygame.image.load("skier_down.png") skier.angle = 0 speed = [0, 6] hit[0].passed = True elif hit[0].type == "flag" and not hit[0].passed: points += 10 obstacles.remove(hit[0]) score_text = font.render("Score: " +str(points), 1, (0, 0, 0)) animate() 自己照着书上的代码敲了半天...
结果敲出来一堆的bug..
这就很气了，然后改了半天
对着程序看了又看。。字母好多敲错顺序了。。
最后还是没有把自己的程序调通，很难受
最后只能参考别人的程序了qaq
但发现程序都好像是2.7版的
好像一条控制字体显示的语句在3.6改了。。。如下
font = pygame.font.SysFont('arial', 50)#这是调好了的！ #原文中它是这样的 ： font = pygame.font.Font(None, 50）
也百度找了好久。。还好找出来了。。不然就真的要崩溃了
