想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Fixes:

- Fixed exception after reverting from creating new vertices and edges in Skinning MOdule
- Fixed PSDImporter broken documentation links in inspectors
- Fixed PSDImporter creates empty GameObject in certain cases
- Fixed Sprite asset used by SpriteSkin in Scene is being deleted
- Fixed Sprite deformation not updated when GameObject is being enabled with SpriteSkin component
- Fixed SpriteSkin always deform even when culled by adding alwaysUpdate option to SpriteSkin to determine if SpriteSkin execution should occur even when the associated SpriteRenderer is culled
- Fixed visual defect after undoing changes to Bone Transform properties in SpriteSkin's Inspector
- SpriteShapeController leaks memory when zero control points are used

Android:
- Cutout is calculated incorrectly when device is not in full screen mode
- Fixed Linear to sRGB color conversion for IMGUI when rendering with Universal RP
- Fixed Linear to sRGB color conversion for Screen Space - Overlay UI when rendering with Universal RP
- Local fullscreen mode setting on Samsung devices is overriden by editor when render outside safe area setting is disabled

Asset Import:
- Fixed AssetImportWorker taking autoconnect player connections

Editor:
- Classes that depend on libMonoPosixHelper.so will now work in playmode in the Linux editor
- Do not resize Editor Windows when polling the mouse position inside of an Editor Window GUI call
- Fixed Console Window not receiving Logs from a built Player until the connection drop-down is clicked
- Fixed IME related APIs in Input class not working, even when using the new Input System package
- Fixed inconsistent Slider behavior when label width is not specified
- Fixed issue with the changing of the size of the input search field
- Fixed missing borders (i.e. inspector window and player settings)
- Fixed the background color and border color of buttons in their various states for IMGUI and UIElements
- Restores previous behavior

GI:
- Fixed crash in PVRTransmissionTextureData after loading another Scene while computing lighting

Graphics:
- ComputeBuffer.SetData sub-updates combined with AsyncGPUReadback fixed in Vulkan
- CopyTexture with element correctly copies 3D texture slices. Previously it only copied the first slice regardless of the specified element
- Filter out SetWantsStructuredBufferBinding for no readable meshes
- Fix a bug where Unity did not bind IndirectArguments ComputeBuffers correctly on D3D12 if the stride was not equal to 4 (the size of a 32-bit integer)
- Fix slow compilation of vfx shaders in big project by not recreating all shaders in that case
- Fixed error messages produced, when using -force-vulkan command line option, when the editor is started

Physics:
- Fix an issue where a child Kinematic Rigidbody2D using Interpolation doesn't correctly follow a parent Dynamic Rigidbody2D also using Interpolation
- Fix an issue where CompositeCollider2D and PolygonCollider2D produce edges which cause unpredictable collision detection using collider cast queries
- Fix to ensure that previous linear/angular velocity/drag after a Rigidbody2D.MovePosition or Rigidbody2D.MoveRotation is restored

Plugins:
- Failed P/Invokes due to plugin not being found are no longer logged to player log because the information is already conveyed through DllNotFoundException

Prefabs:
- Fix null reference exception is thrown when applying modified Button UI component property to prefab

Profiler:
- Fix PVRContextManager thread has no data and occupies important area in Profiler Timeline View
- Fixed an issue whereby the CPU Profiler's 'Show Related Objects' panel could display incorrect names when profiling a build
- Fixed Performance decrease in EditorOverhead using Deep Profile

Scripting:
- Check if scripting is shutting down to prevent an Internal_ApplicationWantsToQuit crash
- Fix rare issue with player crashing on startup when having editor only serialized fields that use abstract classes
- Fixes a performance issue in UnsafeUtility.IsValidNativeContainerElementType() and fixes a bug where UnsafeUtility.IsUnmanaged() could return an incorrect result

- Services: Fix crash in CrashReporting::LogBuffer::RecordLogMessage when called from multiple background threads simultaneously
- Shaders: Surface shader writes into o.Emission channel were ignored in some cases
- UI Elements: Fix USS variable gets corrupted when psuedo state is changed
- Universal Windows Platform: Fixed Cursor image getting visually corrupted when using ExecutableOnly builds
- Universal Windows Platform: Fixed the build failing for certain architecture if there is a native plugin in the project that only targets another CPU architecture (for instead, if your plugin only supports x64 and you're building for ARM64)
- Video: Disabled VideoPlayer warning shows up when VideoClip field gets set to null in OnDestroy() method
- Video: Editor Freezes when trying to import 10-bit video
- WebGL: Allow WebGL build run in background when canvas is not displayed
- Windows: Fixed cursor lock getting lost on Windows 7 when pressing Windows key, then clicking on the task bar and finally clicking back on the game window
- Windows: Native plugins are now put into correct CPU specific architecture folder
- Windows: Unity Crash Handler no longer opens the game process with PROCESS_ALL_ACCESS flag upon the game launch. Instead, it does it only if the game crashes
- XR: Fixed usage flag for foveation map ImageViews during Vulkan multiview framebuffer creation
- XR: The builtin resources zip was not updated after the Font.shader code had been updated to properly handle VR

API Changes:
- 2D: Added: Added API to access SpriteSkin deformed buffer
- Scripting: Added: Included possibility to add public headers to XCode project

Changes:
- 2D: Remove unused Reset Bounds button from SpriteSkinEditor
- Mobile: Removed Game SDK 3.1 initialization due to issues in GameSDK 3.1. Any other GameSDK version is still supported
- Package Manager: Version conflicts involving a direct project dependency are now reported like any other version conflict instead of being silenced

Improvements:
- 2D: Added message to inform user on dependent packages when viewing certain sample Scenes in com.unity.2d.animation
- 2D: Adjust length of popup and value fields for Weight Slider Window in Skinning Module
- 2D: Improved SpriteSkinEditor UI
- Editor: Dragging material over the scene view might be slow: https://unity3d.atlassian.net/browse/EC-612
- Editor: Scene view custom camera FOV is now the actual FOV, makes it easier to make scene & game cameras match (default FOV changed to 60 degrees)
- Editor: Scene view Frame Selected now properly takes custom FOV into account
