Unity4.5.0更新列表
Check out the highlights of this feature-packed release:
450+ Fixes
2D physics makeover
Update to the shader compiler
Improved MonoBehaviour serialization
iOS support for OpenGL ES 3.0
Graphics features:
Shader importing has been massively improved:
Shaders are imported much faster, especially complex surface shaders. Instead of compiling all shader variants for all possible platforms at import time, now the needed shader variants for needed platforms are compiled on-demand. Shader compilation results are cached under Library folder, so identical compilations happen much faster.
Error reporting was improved. Errors are reported on correct lines (imagine that!), and errors in .cginc files report the filename.
Surface shader debugging was improved. No more “#pragma debug” just click “Show generated code” in the inspector.
Added Sparse Texture support (also known as “mega textures” or “tiled textures”). This is a low-level API feature, see SparseTexture class. Implemented on DirectX 11.2 (via tiled resources) and desktop OpenGL (via ARB_sparse_texture).
Added stereoscopic rendering on DX 11.1 (requires Windows 8.1 and compatible hardware).
Introduced support for OpenGL ES 3.0 on iOS devices (starting with A7 devices).
Graphics: Support for 3D textures in OpenGL ES 3.0.
Module Manager:
Introduced Module Manager with updatable platform support. iOS, Android, Windows Phone 8, Blackberry Unity add ons can be updated without downloading full editor installer. Accessed through Modules menu, next to Preferences menu.
Editor features:
New Hierarchy Window sorting – sorting of elements is now based on transform order instead of name.
Introduced new editor API AssetDatabase.FindAssets (string filter, string[] folders). Search the Asset Database for assets by filename, type and asset label. See documentation for more information.
Added Selection.assetGUIDs for getting the current selected assets in the Project Browser. It also returns the folder selection in the first column in the Project Browser (in Two Column mode) which is not part of the main selection.
2D Physics features:
Added 2D Joint Gizmos.
Added new 2D physics component: WheelJoint2D.
Unity Remote upgrade:
Unity Remote 4 is our play testing solution for iOS and Android. As of Unity 4.5, there’ll be no more Wifi latency when playtesting your games on iOS devices. Plus, we’ve added support for the full range of iOS device inputs including accelerometers, gyroscopes and camera images. Unity Remote 4 is available free of charge from Google Play and the App Store.
Mecanim features:
Added CanTransitionToSelf option on AnyState Transitions.
Added new scripting function Animator.Rebind(). You can use this function to manually rebind the animator data set to unity when you change something in your GameObject hierarchy.
For humanoid rigs, in the importer, you can specify a transform node that will be used as root motion for an animation clip. The transform node will replace the automatically extracted root motion computed by Mecanim. (Pro Only).
Windows Store apps features:
Added Compass API to check for compass accuracy.
AppCallbacks methods InvokeOnUIThread and InvokeOnAppThread will detect deadlock and throw exception. Added TryInvokeOnUIThread and TryInvokeOnAppThread, which return true or false instead.
Support for programmatically opening touch screen keyboard.
In Player Preferences added support for scaled resources: splash screen, medium and wide tile, store and small logos.
In Player Preferences added support for Windows 8.1 scaled resources and related settings.
New APIs for changing system cursor – AppCallbacks::SetCursor, AppCallbacks::SetCustomCursor, WSA.Cursor.SetCustomCursor.
Added support for changing screen resolution on Windows 8.1.

Mecanim: Animator does not spam warning messages in standalone.
Mecanim: Humanoid auto-configure now only use rotation information from bind pose. Translations found in bind pose were different from the ones in animation. This was causing undesired retargeting differences.

Substance: Outputs tagged as “Specular” will automatically map to the _SpecTex shader property if present.
Substance: Outputs that are used solely as sources for other outputs’s alpha channels (typically the specular output) are no longer generated separately and will not appear in the project window anymore unless they’re directly assigned to a shader slot or the GenerateAllOutputs option is checked.

Substance: ProceduralMaterial.isCachedDataAvailable was added to check if cache data will be used for a cached ProceduralMaterial or if its outputs will have to be rebuilt. Coupled with DoNothingAndCache, this allows for interactive “installer / substance decompressors” scenes to be created.
Windows Store Apps / WP8: Unity won’t spam warnings for incorrectly unloaded assets, unless explicitly specified.
Windows Store Apps: Independent Input Source is disabled again by default due to delays in Windows Update.
WWW: deprecated ‘WWW(string url, byte[] postData, Hashtable headers)’, use ‘public WWW(string url, byte[] postData, Dictionary&string, string& headers)’ instead.

When determining if non-square textures can produce sprites, check the compressed format for square-requirement. NPOT PVRTC textures are not compressed and therefore are ok for generating sprites.
