支持Windows系统的编辑器
Unity3D V2.5版完全支持Windows Vista和XP,将Mac OS X中的功能和互操作性在Win系统中100%重建了.在两台系统平台上运行相同的引擎,外观和功能都相同.最好的地方就是Unity3D可以在任一平台建立任何游戏--这是跨平台的真正意义! 增强易用性 可以方便快捷的找到您需要的工具.播放按钮放在窗口的上方中部,清晰可见方便你播放,测试和优化你的工程.当你按下按钮时,编辑器将高亮你的游戏窗口而减暗其余的东西,让你更专心的创建发挥你的灵感. 3ds Max的导入 拖放您的*.max文件到编辑器中,包含基于所有骨骼动画,多UV通道及顶点着色.现在已经可以像Unity3D支持Maya,Blender一样的支持Autodesk 3ds Max了.对于其他3D应用程序,Unity3D的Windows平台已经集成了最新的FBX插件. 选项卡式的界面 我们采取最好的方案去设计程序,并已超过几十次的改善改写编辑器.最明显的变化是选项卡似的界面,窗口上的每一部分界面都可以移动,甚至任意将不同的部分结为一个新的工具栏组. 精确的导航和绘制工具 可设定位置,缩放和旋转的定制递增量捕捉.在一定范围内拖拽物体将自动吸附任何物体表面.用我们说的重新设计的旋转工具可以非常方便的在局部坐标系或世界坐标系操作物体. 可完全定制的编辑器 Unity自己的GUI创建系统-UnityGUI,现在整个编辑器允许你调整为属于你自己的独一无二的设计工具,AI控制工具,调试工具,难以调整的工具或其他任何你需要的工具.超过130个权限的API接口使你能够创建专有的编辑工具,并嵌入到现有的编辑器界面.

Additional features, improvements, and changes
Of course we did not just rewrite the editor. We also added some features and fixed some rough corners.
Graphics & Shaders:
Multithreaded mesh skinning. Multicore processors, here we come!
Runtime DXT compression. See WWW.LoadImageIntoTexture and Texture2D.Compress.
Shader Level of Detail support. See Shader.maximumLOD, Shader.globalMaximumLOD.
RenderQueue can be set per-material from script, see Material.renderQueue.
Optimized rendering internals.
Shader compilation is about 3x faster now!
Added #pragma exclude_renderers and #pragma only_renderers directives to shader compiler, to be able to write D3D-only and OpenGL-only shader paths.
Optimized UnityGUI rendering, now it generates less vertices when it can.
NVPerfHUD is supported in Windows standalone games.
Web Player:
Google Chrome browser support (had input problems and crashes on early versions of Chrome).
Internet Explorer 8 support (had input problems when running on Vista).
Windows Web Players have much more stable frame rate.
Editor:
Asset Server client interface completely rewritten. Change-set based interface, log history, and so on!
Scene view can visualize overdraw & optimal texture resolutions (added to RGB/Alpha mode popup).
FBX importing libraries updated to latest version. Fixes lots of issues with FBX, Collada, OBJ, DXF file importing.
FBX user properties are exposed to asset post-processing scripts, see AssetPostprocessor.OnPostprocessGameObjectWithUserProperties.
Added Global transformation tools mode.
Game view Stats window displays frame time and frames per second.
Arrays of enums are properly shown in Inspector.
Added "Show Project Wizard when launching" option to Preferences.
Custom Script/Image editing applications are remembered in Preferences.
Added Terrain wind tint color to terrain settings. Previously it was a hardcoded value.
Added gizmo for Spring Joint and improved gizmos of other joints.
Make default setting for "Recalculate Normals" be off in mesh importer.
Added progress bars for import/export package operations.
Other Improvements:
Application.targetFrameRate. If you want to cap the maximum frame rate to save the planet - now you can!
AnimationClipCurveData has target variable now.
Improved UnityGUI text fields. Now they scroll with cursor if content is too large to fit; selection and cursor display were improved.
Unity on Windows is "large address aware" - so on 64 bit Windows it can use up to 4GB of memory.
Licensing changes: Unity Indie can build standalone games for any platform (they will show splash screen). Unity Indie builds web players with a watermark that goes away after a short period of time.
Bug Fixes
Editor Fixes:
Fixed Character Kerning inspector for custom fonts.
Fix error message when importing Font from a FAT32 filesystem on OS X
Fixed Rotate tool handle location changing with complex hierarchies when it's in Center mode.
Fixed Joints that are connected to themselves.
Fixed Mac vs. PC byte orders in terrain .raw files being swapped.
Mass Place Trees is properly undoable.
Switch texture format to one that has alpha channel when Generate Alpha from Grayscale is enabled.
priority parameter for MenuItem attribute actually works now.
Fixed crash when importing some TrueType fonts.
Error Pause in the console works for script exceptions.
In Cubemap inspector you can create cubemap from skybox images without having to mirror them.
Gizmos.color and Gizmos.matrix are reset before calling any gizmo functions.
Fixed importing progress bar for movies without audio.
Fixed terrain lightmap shaders not working in editor on some old cards (e.g. GeForce 2).
Mesh importer was putting random values into normals and tangents of unused vertices.
Web Player Fixes:
OS X web player correctly clips the game area if it does not fit on screen.
Work around a bug in Vista + Internet Explorer 8 (RC1) where going fullscreen hangs up the browser. Now fullscreen is disabled there :(
Work around Firefox 3.0.x scripting interface bug on OS X that made some games not work.

Fixed OS X web player flicker while scrolling in Firefox.
Graphics Fixes:
Fixed Camera.RenderWithShader in some cases messing up image effects if called from inside of OnPreRender.
Fixed Water becoming blocky on some Intel cards when game is running for many hours. Update Standard Assets and Pro Standard Assets to get the fix!
GUI.DrawTexture fixes: can handle non power of two render textures; fixed 50% opacity when there's no other UnityGUI used; correctly takes GUI.BeginGroup clipping rectangles into account.
Rendering Stats window gathers any rendering done during Update and other functions. Rendering through GL class is captured now as well.
Reported VRAM size should be more robust now on OS X (previously was reporting 256MB for some 512MB cards).
Fixed Texture2D.ReadPixels being upside down when reading from render textures on Windows.
Fixed TexGen ObjectLinear not producing correct texture Z coordinate.
Fixed Movie Textures leaking some memory.
Fixed occasional movie playback crash when movie is more tall than wide and is not power of two in size.

Fixed Animation.IsPlaying for queued animations.
Fixed Application.loadedLevel being initially -1 in players.
Fixed Mesh.tangents producing null reference exception if mesh had no normals nor tangents.
Fixed EventType.ScrollWheel delta values being about 100x too large on Windows compared to OS X (now they match OS X).
Fixed copying text into clipboard producing extra ASCII zero character at the end on OS X.
Fix unrecognized keys (like volume up/down on some keyboards) triggeting unrelated input axes on Windows.
Fixed Mathf.Ceil and Mathf.CeilToInt returning next integer number if the argument was integer already. D'oh!

Fixed crash when streamed video download is cancelled.
Fixed terrain tree colliders for terrains that aren't placed at zero.
Fixed MovieTexture playback issue.
Upgrade Guide
Unity 2.5 projects are compatible with Unity 2.1, so if you do not use new 2.5 features, you can open your projects with Unity 2.1. Timeline window for creating animations directly in Unity was removed in 2.5. Of course you can still author animations in a 3D application. This feature will return even better in Unity 2.6 including High-end Curve Editing and support for animating any property including material animation. Some of the Editor scripting API was refactored, here are the largest changes:
EditorWindow.OnCloseWindow is removed. Use OnDestroy instead.
Hotkey part in MenuItem name requires a space character before the hotkey now.
Removed Mac Ctrl (^) modifier support from MenuItem hotkey.
