摘錄自：設(shè)計(jì)模式與游戲完美開發(fā)
十年磨一劍焕毫，作者將設(shè)計(jì)模式理論巧妙地融入到實(shí)踐中，以一個(gè)游戲的完整實(shí)現(xiàn)呈現(xiàn)設(shè)計(jì)模式的應(yīng)用及經(jīng)驗(yàn)的傳承 《軒轅劍》之父——蔡明宏肥败、資深游戲制作人——李佳澤族跛、Product Evangelist at Unity Technologies——Kelvin Lo、信仁軟件設(shè)計(jì)創(chuàng)辦人—— 賴信仁举娩、資深3D游戲美術(shù)——?jiǎng)⒚鲪? 聯(lián)合推薦全書采用了整合式的項(xiàng)目教學(xué)析校，即以一個(gè)游戲的范例來(lái)應(yīng)用23種設(shè)計(jì)模式的實(shí)現(xiàn)貫穿全書，讓讀者學(xué)習(xí)到整個(gè)游戲開發(fā)的全過(guò)程和作者想要傳承的經(jīng)驗(yàn)铜涉，并以淺顯易懂的比喻來(lái)解析難以理解的設(shè)計(jì)模式智玻，讓想深入了解此領(lǐng)域的讀者更加容易上手。
