想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Features:
- VFX Graph: Added support for Texture2D Arrays in Flipbooks

Improvements:
- Editor: Added profiler markers around test setup, teardown, and execution
- Editor: Improving UTF documentation (DSTR-120)
- Editor: Reduced the per-test overhead of running tests in the editor
- Editor: Reduced the time taken to rebuild the test tree and to scan for assets a test created but did not delete
- Editor: Reduced time taken by filtering operations when only a subset of tests is run
- Package Manager: Added support for opt-in caching of Git LFS files when downloading Git packages. Caching is enabled by setting either of the following environment variables: UPM_ENABLE_GIT_LFS_CACHE or UPM_GIT_LFS_CACHE_PATH. The latter allows overriding the default cache location.
- Package Manager: Fixed an issue where using a Git URL with a revision and a package path in the wrong order would still clone the repository, introducing unnecessary delays before failing with an error.
- Package Manager: Improved logging by adding logs for cache misses and tarball download steps
- Package Manager: Improved the error message when a Git dependency cannot be resolved because the path querystring and revision fragment are in the wrong order
- Package Manager: Increased the amount of information logged to upm.log at various levels
- Package Manager: Optimized Git package download times for repositories using submodules (with Git 2.28.0 or higher installed only)
- Package Manager: Optimized Git package download times, most notably for repositories with a larger history
- Shaders: Reduced shader variant memory usage at runtime and memory consumption while loading shaders

Changed:
- HDRP: Cached the base types of Volume Manager to improve memory and cpu usage.
- HDRP: Reduced the maximal number of bounces for both RTGI and RTR
- Package: Recorder: Fixed an error in the that occurred when setting the build target to macOS standalone from the Editor in Windows
- VFX Graph: Property Binder : Handle Remove Component removing linked hidden scriptable objectfields.

- HDRP: Fixed HDRP material being constantly dirty.
- HDRP: Fixed HDRPAsset loosing its reference to the ray tracing resources when clicking on a different quality level that doesn't have ray tracing
- HDRP: Fixed issue in path tracing, where objects would cast shadows even if not present in the path traced layers
- HDRP: Fixed Nans happening when the history render target is bigger than the current viewport
- HDRP: Fixed SRP batcher not compatible with Decal
- HDRP: Fixed Tube and Disc lights mode selection
- HDRP: Fixed wrong color buffer being bound to pre refraction custom passes.
- IL2CPP: Avoid an error deleting build cache files when a native plugin is marked as read-only in the Unity project directory
- Linux: Converted "X11 did not respond within x milliseconds" error to a logged warning
- Package Manager: Fixed an issue where either no submodules or the wrong submodules could be cloned when using a Git-based dependency with both a path and a revision.
- Package Manager: Fixed an issue where files tracked by Git LFS were not retrieved when using a Git-based dependency with both a path and a revision
- Package Manager: Fixed an issue where the packages-lock.json file was overwritten with the same contents but considered modified by Unity, sometimes resulting in unnecessary operations
- Particles: Added missing particle attributes to the C# Job System integration
- Particles: Fixed crash when using modules with no assigned Particle System
- Physics: Fixed an issue when editing a PolygonCollider2D or EdgeCollider2D where you could delete edges/vertex without limit resulting in an editor tooling exception being thrown
- Physics: Fixed an issue where a negative X or Y local scale on a 2D Collider used by a CompositeCollider2D caused its winding to change resulting in its geometry not handled as a geometric merging operation (union) but instead a subtraction operation
