想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Improvements
- PvrTexTool updated to version 2.10.83.9873. Textures with alpha can now be compressed in Best mode with PVRTC.
- iOS: Added support for "retina" iPad splash screens and icons.

Changes
- Android: Added support for AndroidJavaClass marshaling.
- Android: Removed excessive logging when using AndroidJavaObject et al.
- iOS: Added iOS 5.1 selected in Player Settings.
- iOS: Added iPhoneGeneration.iPad3Gen.
- The Unity version number is always printed to the log file.

Fixes
- Android: APK files created from Eclipse could sometimes not be read, causing the application to close immediately.
- Android: If the Java classpath did not include the current directory ('.') the APK signing step would fail.
- Audio: Fixed audio playback parameters being clamped incorrectly when too many audio sources are playing at the same time.
- Editor: Fixed hang when building very large amounts of asset bundles.
- Editor: Fixed static batching not working when loading level through Application.LoadLevel().
- Editor: When entering play mode hide the 'default' quality settings as they are stripped for build.
- Editor: Fixed out of memory crash while building when having many resources in resource folder.
- Editor: Fixed rare crash when importing material with bumpmap shader but bumpmap texture was not assigned.
- Editor: Fixed rare crash that could occur if user had changed gizmo icon on asset.
- Editor: Fixed crash that would happen if you tried to get the asset path of the material passed to AssetPostprocessor.OnAssingMaterialModel.
- Editor: Fixed bug where animation window would say an animation event has no receivers, when there are multiple MonoBehaviours.
- Editor: Fixed bug where building a scene asset bundle would give incorrect error messages.
- Editor: Fixed title of File saving dialog when building for NaCl (it incorrectly said "Unsupported Build Target").
- Editor: Fixed editor freezing while debugging in some situations.
- Editor: Fix for a situation where changing color in the gradient editor could change color of a previous edited colorfield. (OSX issue only)
- Editor: Fixed shutting down the editor process when opening another or new project from within the editor. (Windows issue only)
- Editor: Fixed crash when incorrect assembly is loaded in some rare scenarios.
- Graphics: Fixed static batching adding extra polygons(meshes) because of extra(unused) materials on input meshes.
- Graphics: Fixed projector culling so it only renders objects inside projector.
- Graphics: Fixed shader compilation for shaders that used a lighting function needing view direction (e.g. BlinnPhong) and passed the 'dualforward' surface directive parameter.
- Graphics: Removed warnings that can be safely ignored ("InsideCameraRender" and "VertexCompNone" warnings).
- Graphics: Fixed lens flare rendering when deferred lighting with an image effect (with the ImageEffectOpaque attribute) was used and there was transparent geometry in the scene.
- iOS: Fixed basic license splash screen issue when application is built with Xcode 4.3.x.
- iOS: Fixed problem when logging to console via System.Console.Write* or JS/Boo print() was throwing exception on iOS 5.1 non-development devices.
- Memory management: Reduced fragmentation in the heap allocators.
- Memory management: Fixed race condition in realloc.
- Mobile: Fixed random crashes with skinned meshes (Cloth in call stack). Re-enabled cloth simulation.
- Mobiles: Fixed skinning performance regression.
- Mobiles: Fixed performance regression with GuiTexture on Adreno devices.
- MonoDevelop: Fixed a case where opening a newly-added script from Unity wouldn't cause the script to get focus.
- Native Client: Fixed loading JPEG files as textures using WWW class.
- OS X and Windows: Fixed very rare crash in SSE mesh skinning code.
- OS X: Fixed standalone crash bug, where it would crash immediately on startup when the "Restore Windows" requester would appear after a previous crash.
- Profiler: Fixed an issue where the player might crash when 'Autoconnect Profiler' was selected.
- Substance: fixed colors being shuffled in the editor during the build process if "Fastest" quality mode is selected.
- Web Player: Prevent Internet Explorer from crashing when more than one tab is used.
- Web Player: Prevent Firefox from hanging on exit.
- Web Player: Fixed bug where editor built incorrect data for compressed meshes in the webplayer.
- Web Player: Make input more responsive for 2.x content.
- Web Player: Fixed crash when assetbundle download was canceled.
- Web Player: Fixed BeginScrollView missing method exception in 3.4 content.
- Windows: Fixed a crash when using SkinnedCloth and switching into fullscreen mode.
- Fixed issue where AssetBundle.Unload(false) caused lots of error messages to be printed when calling Resources.UnloadUnusesAssets () or loading a level.
- Fixed out of memory crash when loading a corrupted .prefab file.
- Fixed memory manager race condition.
- Realtime only lights only affect dynamic geometry. This is the same behaviour as 3.4. Once content is published with 3.5 the fixed renderloop is used.
