想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Fixes:
- 2D: Fixed OnDrawGizmos to Get/Release RenderTexture through CommandBuffer
- AI: Resolve an issue with SamplePathPosition failing due to raycasting very close to the domain boundary
- Animation: Fixed PropertyStream handles not properly picked up in AnimationStream when outside of avatar definition.
- Animation: [Backport] Crash on PreOrderPlayableTraverser::Traverse when entering Play mode in a scene where every GameObject calls OnValidation
- Asset Import: Change an error to a warning in a situation where on re-importing the metafile contained information of removed items
- Asset Pipeline: Fixes editor crash after deleting a prefab using AssetDatabase.DeleteAsset in the OnPostprocessAllAssets
- Build Pipeline: Added the missing build time information in the Editor.log after a build is completed
- Editor: Fix merging with WinMerge
- Editor: Fixed Editor crash in Frame Debugger when Compute Shader is using uninitialized RenderTexture
- Editor: Fixed Frame Debugger to show Compute Shader dispatch information properly
- Editor: Fixed the bold system fonts (verdana) used by prefab
- Editor: Fixes an issue where clicking an active tool in the Tile Palette window would return focus to the previously active Tilemap tool, not the global tool
- GI: Fixed a crash when clicking on Baked Lightmaps tab in the Lighting Setting window
- Graphics: Change Stream source create API to accept audio channels
- Graphics: Corrected normals for Transform-aligned trails
- Graphics: Fix Crash when calling GgpGraphics.GgpStreamSourceCreate
- Graphics: Fixed an issue with incorrect color values in lights after changing between gamma and linear when using URP
- Graphics: Fixed issue loading shaders from a 2017.4 authored asset bundle into more recent Unity versions
- Graphics: Fixed skinned meshes crash when position data is of non-Float32 type
- Graphics: Sorting issue with multiple viewport
- IL2CPP: Correct the stubbed GetEnumerator method on the System.Data.Linq.Table class
- IL2CPP: Discover generic virtual methods on shared generic types properly
- IL2CPP: Prevent a race condition from causing a crash on shutdown when the script debugger is enabled
- Particles: Fix memory leak when using shadow casting lights in the Particle System Lights module
- Particles: Fixed situations where paused systems were having their Stop Actions executed. Paused systems should never have their Stop Actions executed
- Particles: Magnitude property was mapping to the wrong script binding
- Particles: Only allow Texture2D textures in the Shape Module
- Particles: Throw an exception if the offset to Set/GetParticles is invalid
- Physics: Fix the MeshCollider fast midphase not being enabled when upgrading from pre-2019.3, also a better check for a default set of flags that won't get confused when you pick the "Everything" option
- Playables: Fixed issue where Unity would crash when calling RebuildGraph() on a PlayableDirector and destroying it in PlayableBehaviour::OnPlayableDestroy
- Profiler: Added message indicating that Profiler Modules need to be activated to profile
- Scripting: EditorSettings.lineEndingsForNewScripts property now defaults to OSNative, in the 3D Template
- Scripting: Fix intermittent "TypeLoadException: Recursive type definition detected" that was being thrown on playmode start
- Scripting: Fixed locking in mono_get_seq_points (). This fixes a known hang while using the debugger and will eliminate an inconsistent crash in g_hash_table_lookup
- Scripting: [Debugger] Fix crash when there is a generic struct with a field that is an enumerator
- Serialization: Fix undo/prefab diff behavior with [SerializeReference] fields
- UI Elements: Fixed invalid clipping of scaled elements when using content-box clipping mode
- UI Elements: Fixed logging of IMGUI exceptions that only displayed a partial callstack
- UI Elements: The UIElements runtime showed lighter colors in the game view, in linear color space, when compared to the UI Builder
- XR: Fixed Frame timing issue causing incorrect poses on Windows Mixed Reality
- XR: Fixed unstable video and texture buffer resources when using Windows Mixed Reality

Improvements:
- 2D: Improved Memory Allocations
- Scripting: Added locking around tls->frames usage/freeing in the mono debugger. This eliminates some crashes involving memory corruption while using the managed debugger as well as a known hang
- XR: XRInputSubsystem now stops when app is paused, and starts when the app resumes
