WPF實(shí)現(xiàn)2048小游戲

來(lái)源：本站原創(chuàng)|時(shí)間：2020-01-10|欄目：C#教程|點(diǎn)擊：次

前幾天空閑的時(shí)候，實(shí)現(xiàn)了一個(gè)2048游戲。除了可以設(shè)置行數(shù)和列數(shù)之外，支持修改顯示名稱，比如下面，改成神雕俠侶中的角色名稱：

游戲邏輯比較簡(jiǎn)單，大家都應(yīng)該玩過(guò)。

這里主要實(shí)現(xiàn)了四個(gè)類：Game、GameBoard還有ColorBlock和BoardGridLine。

Game類主要用來(lái)實(shí)現(xiàn)游戲的控制，比如初始化、添加新的色塊、移除色塊、控制色塊上下左右移動(dòng)、改變積分，觸發(fā)游戲結(jié)束等。

GameBoard繼承自Canvas，實(shí)現(xiàn)了色塊的合并、檢測(cè)每個(gè)格子的狀態(tài)等，另外提供了Game控制色塊移動(dòng)的接口。

ColorBlock類繼承自Shape類，用于自定義色塊的顯示，包含XY坐標(biāo)、顏色、顯示文字等依賴屬性，可以進(jìn)行動(dòng)畫(huà)，另外還實(shí)現(xiàn)了具體的上下左右移動(dòng)的方法。最初幾個(gè)顏色是手動(dòng)設(shè)置，等到色塊越來(lái)越多，就隨機(jī)生成一種顏色。

BoardGridLine也繼承自Shape類，用于繪制Canvas底部的網(wǎng)格。

另外，游戲使用一個(gè)簡(jiǎn)單的文本文件保存設(shè)置，包括行數(shù)與列數(shù)，以及顯示文字及其對(duì)應(yīng)顏色，具體操作在Settings類中。

最后，按鍵事件封裝在KeysNavigation中。

圖標(biāo)使用Expression Design制作：

游戲效果如下：
