Depth dependence of the loading of packages Assetbundle

Two of the compression mode: Lzma (the default), Lz4

Four kinds of loading method:

1, is loaded from memory: LoadfromMemory () memory

2, loaded from a local: LoadFromFile

3, loading from a local or www server (mentioned below)

4, is loaded from the server unityWebRequest

Load dependent resource bundle

1, the overall configuration dependent (streamingAssets)

2, find all depend on target to load the resources by name

3, load all dependent resources

Lua Lua script plus a suffix file format to bytes

Resource Path:

Application.datapath;

Application.streamingAssetsPath (read-only can not write)

Application.persistentDataPats (special read and write when running!)

Application.temporarycachePath

1, Windows.manifest (total configuration file)

Dependencies: things to a complete show, must be another thing.

2, a single configuration file Assetbundle package: which is recorded

(1) a single resource inside Assetbundle

(2) recording the dependence of the individual Asssetbundle

Dependence bundle package is loaded:

 

 (Wit ha figure by way of example as I)

The first one:

A loading what needs doing that?

1, B and C loading

2. A load

Uninstall A?

1, uninstall B, C dependencies

2, B is determined, whether there is dependent on C B, C uninstall

the second:

Load A?

1, A is determined dependency relationship determination B, C | B, C Analyzing D

Uninstall B?

1, can only uninstall B, D relationship

Uninstall C?

1, uninstall C, D relationship

2, unloading D

Insert a small topic

Reference count:

Gc mechanism is also present relationship reference count: whom references (List <>) who cited (List <>)

The following are three memory storage and the packet bundle loading

 

 1, bundle pack is loaded on a network using WWW and loaded into local, bundle packages load (memory image) by the local method Assetbundle.LoadFromFile

Release memory: Assetbundle.Unload (false)

2，解压Assetbundle：Assetbundle.Load()将镜像里的zip包解压出来

释放内存：Resource.Unloadasset(obj)只能卸载obj类型 shader 网格 材质 贴图都不能卸载 而Resource.Unloadunusedasset()用这个API释放 shader 网格 材质 贴图

3，GameObjece.instance使用解压出来的资释

释放内存：Destroy（）
