本文實例為大家分享了java實現2048游戲源代碼，供大家參考，具體內容如下

一.主要功能：

1、游戲初始化：新建游戲4×4的16宮格畫布，隨機格子上生成2或者4兩個數字2、格子的移動：先判斷能否移動，移動后判斷能否合并，合并后改變格子顏色和數字3、新格子的生成：移動一次，就在剩余的空格子中隨機生成一個2或者44、判贏：16宮格中合并出了“2048”則為游戲勝利5、判輸：16宮格中沒有剩余空格子且不能再向任何方向移動則為游戲失敗

二.項目的主要結構：

在項目2018游戲中，有4個源文件，此外，還有3個.png和兩個.wav格式的音樂文件。一個音樂是按鍵移動的聲音，另外一個是碰撞后的消除的聲音。然后游戲的最高分保存是在Recording源文件中，之后附上所需的圖片文件和音樂文件：

來了來了.
