XASSET 4.0

A more streamlined, efficient and secure Unity Resource Management Solution for you.

New Features

Updater supports checking individual and merged files updates, merged file is a big file which contains all bunch of resources generated by VFS technology, it requires enable VFS to use, or it will only download individual files fo updates.
VFS supports specific file prefix to read and write, which is a highly efficient resource-encryption solution, and it considerable enhanced IO performance in Android devices.
Versions supports version conrtols for resource files in any prefix, which is easier to control Wwise,Fmod,etc. resources.
Downloader supports resume download from breakpoint, verify fingerprint, restore exceptions (Automatically Redownload if download failed), and modify concurrent number of downloads.
SearchPath a more intelligent search path machinism.
Lazy GC a more efficient resource collect strategy.

Runtime Mode: can be used in Unity Editor without building AssetBundles, which means there is no need to waste time on waiting builds while developing.
Does not Depend on Coroutines: compare to other solutions which highly depends coroutine, XAsset performs better, and developers can use less codes to write nicer and more efficient asynchronous parallel codes.
Use reference counts to manage life cycle of object: Avoid repeated loads and accidentally unload, which can properly handle life cycle of objects. It doesn't use weak reference, which is more convinient to use in multiple coding language environment, eg. avoid C# has to wait for Lua to call GC so it can recycle resource while cross-referencing in C# and Lua.
Rule based strategy for Build AssetBundles: After set the rules, base-code will automatically collect all resources to build, and will analyse the redundancies and confilcts, then optimize automatically. It can effectively solve the redundancy of most non-built-in resources.
Non-generic API design: more friendly to Lua, more convinient to use in multiple coding language environment.

为你提供更精简、高效、安全的Unity资源管理方案。

Updater 支持大小包版本更新检查的程序，大包是把基于VFS技术生成的一种包含了所有资源文件的大文件，需要开启VFS才能使用，不开启或者已经下载过大包之后，只会进行小包更新。
VFS 自定义格式的文件读写支持，实现了一种非常高效的资源加密方案，并且在测试的Android设备上改方案可以让资源加载的IO性能得到可观的提升。
Versions 支持任意格式的资源文件的版本管理，可以非常方便的对Wwise、Fmod等自定义格式的文件进行版本控制。
Downloader 支持断点续传、指纹校验、异常复原（下载失败后自动重新下载）和并发数量配置的资源下载组件。
SearchPath 更智能的寻址机制。
Lazy GC 更高效的资源回收策略。

开发模式：编辑器下可以在不用构建AB的环境中使用，平常开发时可以无需为漫长的Build过程耗费大量的时间。
对协程无依赖：相对于高度依赖协程的方案，这种设计不但在性能上更有优势，同时，业务层可以用更少的Coding写出更优雅高效的并行异步加载业务。
用引用计数管理对象生命周期：避免重复加载与轻易卸载，让资源对象的生命周期得到妥善处理。并且没有使用WeakReference，可以更方便在跨语言环境中使用，例如避免Lua和C#的交叉引用导致C#这边需要等Lua先GC才能回收资源。
基于规则配置的打包策略，配置好打包规则后，底层会自动收集所有要打包的资源，并分析其冗余和冲突，再进行自动优化，可以有效的解决大部分非内建的资源的冗余情况。
非泛型接口设计: 对Lua更友好，可以更方便的在跨语言的环境中使用。
