1）本篇教程将讲述如何输出EffectGroup特效组。
|
|||
|
|
2）我们打开Example文件夹下的Example_4场景文件，目录位置如图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
3）Example_4场景内如图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
4）我们选中Fx_Portals_01，打开菜单栏Egret3D-->Tools-->AddEffectsGroup,为Fx_Portals_01添加EffectGroup脚本，脚本内有auto（自动播放）和
|
|||
|
|
Loop（循环）可以勾选，由于该特效制作的时候已经循环，本次的导出只勾选自动，如下图所示：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
5) 确认无误后，打开菜单栏Egret3D-->Export-->EffectGroup,打开特效组导出界面：
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
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，这里将罗列出将要导出的所有资源。
|
|||
|
|
|
|||
|
|
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，effect.e3dPack和effect.e3dPackc，其中e3dPackc使用zip压缩，由于游览器限制问题，这里我们使用
|
|||
|
|
effect.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>
