Java貪吃蛇游戲完善版

更新時間：2021年09月13日 16:02:29 作者：技術(shù)宅--火狼

這篇文章主要為大家詳細介紹了Java貪吃蛇游戲完善版，支持菜單操作，鍵盤監(jiān)聽，可加速，減速，統(tǒng)計得分等功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

很認真的寫的一個java版的貪吃蛇游戲，圖形界面，支持菜單操作，鍵盤監(jiān)聽，可加速，減速，統(tǒng)計得分，設定運動速度，設定游戲背景顏色等！應該沒有Bug了，因為全被我修改沒了。

下面是項目各包及類的層次關(guān)系：

游戲的主要運行界面截圖如下：

下面是部分代碼，詳細源碼見此鏈接：貪吃蛇源碼下載
