Pygame制作简单的跑酷游戏

今天我们来看看如何使用Pygame框架制作一个简单的跑酷游戏。这个游戏包含了基本的游戏元素,如玩家角色、障碍物、背景、音效等,可以作为入门Pygame游戏开发的一个不错的示例。

游戏概述

这是一个简单的横版跑酷游戏,玩家控制一个忍者角色,通过跳跃来躲避迎面而来的各种障碍物(汽车、飞机、外星人等)。游戏有三个状态:准备、游戏中和结束。

主要的游戏元素包括:

玩家角色(忍者)
障碍物(汽车、飞机等)  
滚动背景
音效和背景音乐
计分系统
游戏UI(开始、结束界面等)

代码结构

游戏的主要代码结构如下:
class AudioManage:  # 音频管理
class BaseSprite:   # 基础精灵类
class EnemySprite:  # 敌人精灵  
class EnemyManage:  # 敌人管理
class PlayerSprite: # 玩家精灵
class PlayerManage: # 玩家管理 
class BGSprite:     # 背景精灵
class BGManage:     # 背景管理
class UISprite:     # UI精灵
class UIManage:     # UI管理
class GameManage:   # 游戏主管理类

关键实现

1. 玩家控制

玩家通过上键控制忍者跳跃:

def is_jump(self):
    if self.jump_count > 0:
        AudioManage().set_sound_music(5)
        self.jump_count -= 1
        self.velocity_y = -12
    self.jump()

2. 障碍物生成

通过定时器事件定期生成新的障碍物:

pygame.time.set_timer(ENEMY_BORN, BORN_RATE)
 
# 在事件循环中
if event.type == ENEMY_BORN:
    self.enemy.broth()

3. 碰撞检测

使用pygame的sprite collision检测玩家与障碍物的碰撞:
 

r = pygame.sprite.groupcollide(self.enemy.enemy_group, self.player.player_group, False, False)
if r:
    # 处理碰撞后的游戏结束逻辑

4. 背景滚动

通过不断移动两个背景图片实现无缝滚动:

def update(self):
    self.rect.left -= self.speed
    if self.rect.left <= -WIDTH:
        self.rect.left = WIDTH

完整代码

这里我把我的代码放在这里,给大家做个参考，里面还有很多不完善的地方，图片素材什么的也需要大家自行寻找，我的素材大多数都是使用 " 非常糟糕的城市 " 这个游戏的图片素材。
