萌趣赛博电子宠物，养一只属于你的屏幕小怪兽
2026-10-156
哈喽各位创客小伙伴！最近参加社区造点好玩的活动，拿行空板做了一款桌面电子小宠物。之前版本存在耳朵裁切、进度条溢出等小bug，我反复调试修复完成，现在分享完整项目给大家。
这只小怪兽拥有完整的生命行为：会闲逛溜达、发呆放空、眨眼、呼呼大睡，睡觉还会冒“Z”符号；屏幕随机刷新金色小零食，小家伙看到食物会兴奋，吃到零食还会弹跳庆祝，吃够食物就能升级；支持手指直接拖拽把玩，移动的时候身后还会拖着淡淡的渐变尾迹；定时弹出趣味对话气泡，UI界面带等级进度条，底部实时显示宠物当前状态。所有界面做了边界保护，耳朵、文字、对话框不会被屏幕边缘切掉，直接复制代码即可跑通。

✨玩法说明
1. 将完整代码复制粘贴到Mind+的Python积木模式-手动编辑，上传到行空板，程序立刻运行。
2. 直接用手指触摸屏幕上的小怪兽，就可以拖拽它到处溜达。
3. 等待金色食物随机刷新，小怪兽靠近食物会进入开心状态，吃到食物会触发弹跳进食动画。
4. 吃够指定数量食物宠物就升级，最高10级。
5. 宠物会自主切换多种行为：闲逛、发呆、眨眼、睡觉，睡觉的时候会冒出“Z”符号，还会时不时弹出对话气泡。
效果展示
-------------------------------------
二次改造小思路
玩够原版还可以继续DIY，简单改几个参数就能做出不一样的效果：
- 修改 greeting_list 列表，替换成中文对话；
- 修改颜色十六进制码，给小怪兽换一套皮肤配色；
- 修改 max_level ，调整宠物最大等级；
- 修改 food_need_per_level ，控制每一级需要吃掉多少份食物。
这个项目把GUI绘图、触摸交互、状态机动画、等级系统结合在一起，很适合行空板新手学习参考。如果大家有好玩的修改想法，欢迎评论区一起交流！
