想做遊戲但不知從哪開始，Unity能幫你什麼

What's new in this version:

Fixes:
- macOS: Fixes an issue with macOS Catalina that causes Unity to request permission to receive keyboard input when using other apps in both the editor and standalone player
- Android: Application.Quit will correctly quit the application process, previously it would only destroy Unity runtime, keeping activity alive, that lead to incorrect application resume
- Android: Fixed a Vulkan video playback crash
- Apple TV: Fixed regression, where clicking B on gamepad would show "JoystickButton0" as pressed
- Apple TV: GetKeyDown and GetKeyUp will work correctly with Siri Remote buttons. Due platform limitation, GetKeyDown, GetKeyUp will work with delay when receiving events from keyboard, see documentation for more info
- Apple TV: Pressing menu button on Siri remote will correctly exit to home screen, if tvOS.Remote.allowExitToHome is set to true
- Asset Import: Local fileIDs of FBX meshes are correctly upgraded from Unity 2018 and previous version when multiple meshes share the same name
- Editor: Fix incorrect colorspace for IMGUI in GameView
- Editor: MacEditor: "Unsupported image when converting for NSImage" log is now a DebugAssert, which will prevent the assert from being logged on build machines
- Editor: Project Settings Window fails to appear after installing the Ryder Editor package
- Graphics: Fixed crash in the Editor that could be caused by having optimization enabled on meshes with empty sub-objects
- Graphics: Fixed rare deadlock in CreateGpuProgram when multithreaded rendering is enabled on mobile devices
- IL2CPP: Fixed a crash when accessing the LocalEndpoint property of a socket using an IPV6 connection
- IL2CPP: Fixed an issue with nested type metadata being re-initialized without checking for previous initialization, which caused a memory leak in certain situations
- Kernel: Fixed player crash due to stack overflow in Loading.PreloadManager thread
- Package Manager: Fix OSX - Package Manifest is not editable due to permission errors
- Particles: Fix a case where particle trails could flicker if their owning system used ParticleSystem.SetParticles in script during LateUpdate
- Particles: Fix a crash if using a non-read-write mesh from an Asset Bundle in the Particle System Shape Module
- Particles: Fix case where trails sometiems did not disappear
- Particles: Fix erroneous GetTransformInfoExpectUpToDate message
- Particles: Fixed case where Auto Random Seed was ignored for the Emission Rate property
- Physics: Fixed an issue when reparenting a GameObject with multiple static Collider2D which resulted in them not being correctly attached to the parent Rigidbody2D
- Physics: Fixed crash when changing Collider2D rigidbody while contacts are still active
- Physics: Fixed incorrect use of initial rotation of Rigidbody2D connected via a HingeJoint2D
- Prefabs: Added GameObjects and components with a DontSave flag (specifically DontSaveInEditor) will no longer show up in the Prefab overrides dropdown since they don't get applied or reverted anyway
- Profiler: Fixed crash when profiler runs out of memory budget on Job threads
- ps4: Fix camera HDR textures
- Scripting: ClampBlendShapes are now set to false by default when loading a 3D template
- Scripting: Editor: Added missing 2018_4_OR_NEWER C# preprocessor directive when compiling C# scripts
- Serialization: Editor: Fixed issue with SerializedProperty.objectReferenceInstanceIDValue emitting asserts to the console
- Shaders: Improved generation of GLSL Tessellation shaders in more situations
- Terrain: Brush inspector no longer spams Undo events, preventing Undo from working while it was open
- Windows: Allow P/Invoke calls where the library extension is included in the library file name in the [DllImport] attribute
