 <td style="width:415.3pt;"> <h3 style="margin-left:0pt;">立钻哥哥：Unity是一个入门快、提高难的游戏引擎，想要提升能力，至少需要越过3道坎：API+Shader+综合能力；</h3> ++1、API的积累：对API的合理利用不仅可以减轻自己的编码负担，而且往往可以提高程序的运行效率；这也是钻哥开始“Unity API”独立打造分类的初衷； ++2、Shader编程：想要做出一款精品游戏往往需要有高效的Shader的支持；Unity提供了一套改良的“Shader Lab”系统，优化了繁杂的“Open GL”编程； ++3、综合能力（技术+业务+管理）：一款产品的制作除了功能编程外，往往会涉及很多其他领域，例如产品架构、UI交互设计、模型制作等，作为主要的编程人员，对其他相关领域的了解程序往往会影响到产品制作直至最后的产品体验； ++++立钻哥哥一直在推动【VR云游戏=Unity+SteamVR+云技术+5G+AI】，这个只是一个引子，抛砖引玉让大家对整个知识体系有一个明确的落地方向，宝宝们可以根据自己的兴趣方向进行拓展：比如Unity这里是指一种“3D游戏引擎”，也可拓展至“UE4、Cocos2dx”等游戏引擎；SteamVR是一种跨硬件解决方案，也可拓展至“VRTK”等第三方插件；“云技术+5G”是一种跨平台解决方案的核心技术，同样可拓展至其他平台解决方案；AI也是一种先进技术的举例，也可以拓展至任何一种前沿技术； </td>
