# the 2048's code

程式碼已經長到我手機沒辦法一次複製全部了，所以我拆成了兩個part貼上，如果你們想要玩，要記得貼在同一個檔案裡面，part 2直接接在part 1下面就可以了。
如果嫌麻煩也可以前往我的Githib直接下載檔案，如果會用的話。
我所有物件都是pygame直接畫出來的，所以不用額外下載任何檔案、照片lol，只要終端機⬇️

pip install pygame

就可以玩

## 遊玩方法
1. 繼續往下看、自己複製 -> [程式碼](##程式碼)
2. 前往專屬Github(更新較快) -> [2048-made-with-pygame](https://github.com/honzhe05/2048-made-with-pygame)

## What's new
> [name=hzzz]
> [time=Sat, Nov 1, 2025]
1. 新增滑動、合併及新增方塊時的動畫。
2. 可調整螢幕尺寸300, 400, 500, 600px。
3. 重新開始及死亡畫面。

>
> [time=Fir, Oct 31, 2025]
1. 新增遊戲。
