JavaScript => var mainAsset: Object;
C# => Object mainAsset;

Description 描述

Main asset that was supplied when building the asset bundle (Read Only).

主资源是在构建资源包时指定（只读）。

This is a convenience function that makes it easy to find the primary asset of a bundle. For example you might want to have a prefab of a character and include all textures, materials, meshes and animations files with it. But the fully rigged prefab of the character would be your mainAsset and can easily be accessed.

该功能可以方便的找到bundle内的主资源。例如，你也许想有一个角色的预制体并包括所有纹理、材质、网格和动画文件。但是完全操纵角色的预设体应该是你的mainAsset并且易于被访问。

JavaScript:

function Start () {
	var www = WWW ("http://myserver/myBundle.unity3d");
	yield www;
	// Get the designated main asset and instantiate it.
	Instantiate(www.assetBundle.mainAsset);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
	IEnumerator getAsset () {
		WWW www = new WWW ("http://myserver/myBundle.unity3d");
		yield return www;
		// Get the designated main asset and instantiate it.
		Instantiate(www.assetBundle.mainAsset);
	}
}
