這篇文章主要介紹了如何利用Java實(shí)現(xiàn)經(jīng)典的游戲—打磚塊。玩家操作一根螢?zāi)簧纤降摹鞍糇印?，讓一顆不斷彈來(lái)彈去的“球”在撞擊作為過(guò)關(guān)目標(biāo)消去的“磚塊”的途中不會(huì)落到螢?zāi)坏紫隆８信d趣的小伙伴可以了解一下
前言
《JAVA打磚塊》游戲是自制的游戲。玩家操作一根螢?zāi)簧纤降?ldquo;棒子”，讓一顆不斷彈來(lái)彈去的“球”在撞擊作為過(guò)關(guān)目標(biāo)消去的“磚塊”的途中不會(huì)落到螢?zāi)坏紫隆?/p>
主要設(shè)計(jì)
- 設(shè)計(jì)游戲界面，用swing實(shí)現(xiàn)
- 設(shè)計(jì)磚塊，磚塊類，
- 設(shè)計(jì)小球，滿屏亂跑的小球類，負(fù)責(zé)打碎磚塊
- 設(shè)計(jì)棒子，左右移動(dòng)的木頭板類
- 球碰到磚塊、棒子與底下以外的三邊會(huì)反彈，落到底下會(huì)失去一顆球，把磚塊全部消去就可以破關(guān)。
- 小球碰到磚塊的回調(diào)算法設(shè)計(jì)
- 小球碰到棒子的回調(diào)算法設(shè)計(jì)
- 設(shè)計(jì)碰撞特效，一個(gè)負(fù)責(zé)顯示爆炸效果的類
- 設(shè)計(jì)音效類，碰撞時(shí)發(fā)出音效。

java的一些基本語(yǔ)法，比如數(shù)據(jù)類型、運(yùn)算符、程序流程控制和數(shù)組等，理解更加透徹。java最核心的核心就是面向?qū)ο笏枷耄瑢?duì)于這一個(gè)概念，終于悟到了一些。
