#《UnityAPI.GameObject游戏对象》发布说明：

++++“UnityAPI.GameObject游戏对象”是对UnityAPI中GameObject类的剖析和拓展；

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；

++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；

 

 

@@提示：有些博客可能只是开了头，如果感兴趣的同学，可以“点赞”或“评论区留言”，只要关注的同学多了，那就会继续完善哟！（“++==”，表示没有写完的，如果关注度不高就不完善了；“++ok++”，表示此篇博客已经完成，是阶段性完整的！）

++++VR云游戏=Unity+SteamVR+云技术+5G+AI；（说明：AI人工智能不是我们的主要研究技术，只是了解一下，领略一下有风的感觉！但是，VR是我们的研究重点）

Unity VR开发环境搭建避坑指南 本文总结了Unity VR开发环境搭建的常见问题与解决方案。新手常犯的错误包括：随意下载安装包导致版本不匹配、忽略LTS版本的重要性、设备连接后未正确配置XR插件等。通过对比2020年失败的首次尝试与2023年的正确方法，文章强调必须严格遵循安装流程：1)使用Unity Hub静默安装；2)选择2022.3 LTS等稳定版本；3)确保SDK与Unity版本兼容。核心教训是VR开发环境重在"正确配置"而非简单安装，稳定性比追新更重要。文中用伪代码形式详

unity3d性能优化之将GameObject标记为静态
栗少的博客
04-08 1200
所谓静态就是静止的，如果要改变了它的位置，就不是静态的了，静态物体在脚本加载的时候就开始渲染，不随着update 每帧更新，如果要移动物体，就必然要重新刷新，就是动态的了 ，即使你把移动的物体勾选了static，draw calls 也并不会减少,并且效率和原先的一样没有得到优化。所以通常一直静止的游戏物体，才会勾选static，比如有些游戏场景是不动的，而游戏场景又很占资源，这个时候就可以勾选static了。而标记为static后，可以优化效率，使游戏更加流畅。

4. 创建改变物体大小的脚本：1. 创建新脚本： •在Project窗口中，右键点击并选择Create > C# Script来创建一个新的C#脚本。将你想要控制大小的物体拖到事件列表的空白区域，然后选择Change Size（如果你已经创建了一个用于改变大小的脚本）或任何其他相关的方法。创建一个平面，放置来获取摄像头的实时画面的图片，添加想放至的模型，摆放好位置，然后可以给物体添加动画，在动画编辑器操作，如下图。现在，你已经成功添加了UI画布和按钮来控制物体的大小，并添加了背景音乐。

在某些情况下，自定义动画控制器可以更好地满足游戏需求。通过脚本编写自定义控制器，可以实现更复杂的动画逻辑。// 自定义动画控制器// 自定义动画控制器 using UnityEngine;// 加载动画片段 idleClip = Resources . Load < AnimationClip >("Animations/Idle");// 获取输入 float verticalInput = Input . GetAxis("Vertical");
