一、项目简介

今天给大家分享一个纯 Python + Pygame 实现的回合制卡牌对战小游戏。

这是一个非常适合新手练手的经典小游戏项目，包含了市面上卡牌游戏最核心的机制：

• ✅ 回合制对战（玩家回合 / AI 电脑回合）

• ✅ 卡牌飞行攻击动画

• ✅ 自动抽卡系统（永久不会断牌）

• ✅ 卡牌互相伤害、死亡判定

• ✅ 双方血量条实时更新

• ✅ 无牌卡死终极修复（全网最稳）

• ✅ 单方面无牌、双方无牌自动结算胜负

• ✅ 中文显示、卡牌选中高亮

游戏玩法简单：选中自己卡牌 → 点击敌方卡牌攻击 → 回合交替对战，血量清零即失败。

二、游戏运行效果

1. 开局双方各 5 张手牌，每回合自动抽卡，不会空牌库

2. 玩家手动操作攻击，电脑自动 AI 攻击

3. 卡牌攻击有飞行动画，对战手感流畅

4. 支持多种胜负判定：血量归零、敌方无牌、我方无牌、双方无牌平局

三、核心难点解决（重点！）

很多同学写卡牌游戏都会遇到 3 个致命 bug，我全部修复了：

1. 卡牌攻击后位置错乱、点击失效

原因：卡牌攻击飞出去后坐标不复位，导致点击位置和实际位置不一致。

解决方案：固定卡牌初始位置，动画结束强制归位 + 实时刷新点击碰撞框。

2. 打光卡牌后游戏卡死、无法结算

原版代码只会判血量为0，不会判无牌状态，导致双方无牌后画面静止。

本次新增：

• 敌方无牌 → 玩家胜利

• 我方无牌 → 电脑胜利

• 双方无牌 → 按血量高低判定胜负/平局

3. 方法名与属性名重名报错（int无法调用）

新手极易踩坑：attack 既是攻击力变量又是方法，导致代码崩溃。

修复：攻击力字段改为 attack_power，攻击方法改为 attack_card，彻底规避冲突。

四、完整可运行源码

先在终端下载好插件pygame

pip install pygame

直接新建 game.py 输入如下全部代码即可运行：

import pygame
import random
import sys
import os

# 初始化Pygame
pygame.init()
WIDTH, HEIGHT = 1200, 700

GRAY = (30, 30, 50)
YELLOW = (255, 200, 0)

五、游戏操作说明

1. 第一步：点击自己的卡牌（底部卡牌，出现黄色边框代表选中）

2. 第二步：点击敌方卡牌发起攻击

3. 攻击后自动切换电脑回合，电脑自动抽卡、自动攻击

4. 每回合自动抽卡，永远不会断牌

5. 任意一方无牌 / 血量归零立即结束游戏

六、项目亮点总结

• 完整回合制逻辑，结构清晰，适合二次开发

• 修复了网上所有同类代码的卡死、点击失效、坐标错乱Bug

• 自带 40 张超大牌库，游戏耐玩

• 全自动 AI 对手，无需人工干预

• 适配中文、动画流畅、UI 简洁

七、可拓展方向（可以自己继续升级）

• 给卡牌添加技能、暴击、护盾

• 添加音效、出牌特效

• 新增更多卡牌种类

• 添加回合倒计时、游戏计分

• 实现玩家 vs 玩家双人模式
