简介:长江后浪推前浪,在游戏行业尤其如此。随着硬件技术的提高,软件技术也不断地更新换代以提供缎带人们更好的视觉效果,游戏体验,但总有一些东西让你很难说清他们是否真的能被取代。或许有人说这仅仅是一种情怀,但不可否认有些东西的确有它自己独特的地方,因此而难以被取代,比如2D游戏。在如今3D游戏愈来愈流行的游戏行业,2D游戏的很多方面都显得过时,但是它所具有的一些优势的确是3D游戏所不具备的。相比3D游戏,它的团队规模更小,因此也更容易控制;它的动画制作相对3D要简单得多;而在编程方面2D游戏的控制也要简单得多;还有一点必须要说的就是2D游戏的像素艺术,或许有人说3D游戏在图像的表现方面优于像素艺术很多,但是不得不承认它给2D游戏的制作带来了很多有利条件,而青尧个人也很喜欢像素艺术。技术的进步对于游戏行业来说是一件好事,青尧说不好2D游戏是否会死去,但是我还是愿意祝福它能够走得更远。对这方面如果读者与青尧有不同的观点请与青尧联系:huoxiaoxia@cngda.com或在线投稿:http://tougao.chinagcn.com。
简介:摘要:本文基于以传统文化越剧为主题秉持创新、创意、个性等元素内容,打造一款具有独特美术风格弘扬文传统文化越剧的游戏。根据传统越剧特有的剧目、唱、念、做等各种文化打造游戏独特的美术风格,根据传统越剧唱腔所具有的独创性强的特点打造独特的音乐风格。以游戏特有的艺术表达形式融合越剧文化加以趣味性的创新,以弘扬传统越剧文化。
