// Now its getting hairy. The devil is in the details here, the big issue is jumping of course. // * When jumping up and down we dont want to center the guy in screen space. // This is important to give a feel for how high you jump and avoiding large camera movements. // * At the same time we dont want him to ever go out of screen and we want all rotations to be totally smooth. // So here is what we will do: // 1. We first find the rotation around the y axis. Thus he is always centered on the y-axis // 2. When grounded we make him be centered // 3. When jumping we keep the camera rotation but rotate the camera to get him back into view if his head is above some threshold // 4.

封装库/工具库中重要概念之动画 前端开发中，动画是一个非常重要的技术特性。它可以提升用户体验，增加页面交互性，并且让网站看起来更加生动活泼。然而，在实现复杂动画时，手写代码往往会变得繁琐且容易出错。因此，前端工具库和封装库的出现为我们提供了便利。在本文中，我们将探讨前端中的封装库和工具库以及它们在实现动画效果方面的作用。
unity程序使用云渲染技术是否要修改？ unity引擎开发的程序使用了点量云渲染系统后，为啥不用对程序修改就可以实现手机和平板中直接使用呢？这是因为云渲染系统，对于操控方式是键盘或者鼠标的Unity或者UE4程序，会在手机中模拟出鼠摇杆和软键盘，这样就可以像在电脑上一样完成交互了。当然如果手机或者平板能连蓝牙，也可以外接鼠标完成交互。**所以使用实时云渲染技术是无需对现有程序做修改的，程序在Windows使用是如何建模的，还是按照原来的方式建模即可
【Unity3D 灵巧小知识点】☀️ | Unity脚本生命周期 Unity小科普 老规矩，先介绍一下 Unity 的科普小知识： Unity是 实时3D互动内容创作和运营平台 。 包括游戏开发、美术、建筑、汽车设计、影视在内的所有创作者，借助 Unity 将创意变成现实。 Unity 平台提供一整套完善的软件解决方案，可用于创作、运营和变现任何实时互动的2D和3D内容，支持平台包括手机、平板电脑、PC、游戏主机、增强现实和虚拟现实设备。 也可以简单把 Unity 理解为一个游戏引擎，可以用来专业制作游戏！

unity 如何脚本间交互 如何脚本间交互：方法1: 通过在编辑器里面拖动，来持有这个对象去调用对应的函数，这个方法比较简单。 在编辑器中新建2个脚本。 我们写一个a脚本 public class Ascript : MonoBehaviour { // Use this for initialization void St...
