1）前两篇教程我们讲述了，如何调节材质球和如何输出mesh信息，本篇教程将进一步讲解如何输出SkinnedMesh。
|
|||
|
|
2）我们打开Example文件夹下的Example_3场景文件，目录位置如图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
3）场景内我们可以看到一个Character对象,如下图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
4）导出SkinnedMesh前，我们首先确认导出的SkinnedMesh的蒙皮骨骼数目是没有超出48根，同时骨骼系内不能存在骨骼缩放，然后我们需要参考Material设置教程中的
|
|||
|
|
设置修改各个Material Shader参数设置，务必使用插件提供的材质球Shader。修改完毕后如下图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
5）然后我们选择菜单栏Egret3D-->Export-->SkinnedMesh,打开SkinnedMesh导出工具。
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
6）参考上图中的面板图片，接下来详细的说明一下面板上的参数用途：
|
|||
|
|
a) No Vertex Color In Mesh：
|
|||
|
|
导出时，勾选此项将不输出Mesh信息内的顶点色信息，使用引擎内默认值替代，导出文件大小将得到优化。
|
|||
|
|
b) Is Resource Compressed:
|
|||
|
|
导出时，勾选此项将同时输出一份压缩格式的资源。
|
|||
|
|
c) 导出对象信息表：
|
|||
|
|
Ⅰ）AnimationList：骨骼动画列表，展开后可以看到所有导出的骨骼动画名字。
|
|||
|
|
Ⅱ）Roots：根骨骼列表，可以识别常用的几个根骨骼名称，导出前需要展开确认根骨骼导出时候正确，是否存在缺失或者绑定对象错误等问题，如果存在多个
|
|||
|
|
根骨骼需要手动添加至列表中。
|
|||
|
|
Ⅲ）SkinnedMesh：mesh导出列表，确认导出的mesh已经全部修改为插件提供的材质球Shader。
|
|||
|
|
Ⅳ）MeshInBone：如果需要在骨骼系内添加mesh，从而到达mesh跟随骨骼运动，需要手动添加mesh至该列表中。
|
|||
|
|
|
|||
|
|
7）参数确认无误后，我们可以点击Export进行导出，本次导出我们导出了一个压缩版本和未压缩版本，接下来我们使用压缩版本来进行资源加载：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
8) 打开压缩资源目录，可以看到两个文件，character.e3dPack和character.e3dPackc，其中e3dPackc使用zip压缩，由于游览器限制问题，这里我们使用
|
|||
|
|
character.e3dPack拷贝至main目录下：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
9）测试代码：
|
|||
|
|
a) Main.ts
|
|||
|
|
class Main extends egret.DisplayObject {
|
|||
|
|
// Canvas操作对象
|
|||
|
|
protected _egret3DCanvas: egret3d.Egret3DCanvas;
|
|||
|
|
|
|||
|
|
// View3D操作对象
|
|||
|
|
protected _view3D: egret3d.View3D;
|
|||
|
|
/**
|
|||
|
|
* look at 摄像机控制器 。</p>
|
|||
|
|
* 指定摄像机看向的目标对象。</p>
|
|||
|
|
* 1.按下鼠标左键并移动鼠标可以使摄像机绕着目标进行旋转。</p>
|
|||
|
|
* 2.按下键盘的(w s a d) 可以摄像机(上 下 左 右)移动。</p>
|
|||
|
|
* 3.滑动鼠标滚轮可以控制摄像机的视距。</p>
