Release Notes Search

Removed: Removed the GameCenter implementation.

Removed: The deprecated iPhoneInput class has been removed. Use Input instead.

Added: Added MemoryLabel.Create.

Added: The former com.unity.collections has been moved into an engine module, namely ManagedKernelModule. It is now available irrespective of whether the package is used, and the package is reduced to a set of typeforwarders. As part of this move, the scripting define UNITY_DOTS_DEBUG no longer controls extra checks in players in Native and Unsafe collections (although it still does control many extra checks in Entities); now you need to use the Checked (or Debug) managed code variant to include those checks in player builds.

Added: Added support for replicating non-uniform (3D) scale via the Unity.Transforms.PostTransformMatrix component, using the new built-in PostTransformMatrix3DScaleVariant. Rather than sending the full float4x4 matrix, only the per-axis scale is extracted and replicated (as three quantized floats by default). Existing ghost prefabs will have the DontSerializeVariant set by default for PostTransformMatrix to not break existing behavior. Use the new SubType = GhostFieldSubType.PostTransformMatrixScale to create your own Variants.

Removed: The obsolete managed GhostPresentationGameObjectPrefab component is now a hard error ([Obsolete(..., true)]) and no longer functional. Use the unmanaged UnmanagedGhostPresentationGameObjectPrefab instead, which references the prefabs through UnityObjectRef<GameObject>.

Added: Added PhysicsSceneLoadScope which can be used to control which physics scene is used when loading a unity scene asset. This effectively allows grouping multiple unity scenes under a specific physics scene.

Added: Added "ChainSegment.UpdateSegments()" to update the segments. This compliments the existing "ChainSegment.CreateSegments()".

Added: Added "Get()" extension method to all Physics "object" types to allow users to work around not being able to use a setter property on a returned object without first assigned to a local variable. Added to PhysicWorld, PhysicsBody, PhysicsShape, PhysicsChain, PhysicsJoint and all concrete PhysicsJoints.

Added: Added "PhysicsUserData.vector3IntValue" property of type Vector3Int. This will allow per-shape tilemap position references.

Added: Added a "massOverride" property to PhysicsBody and PhysicsBodyDefinition that selects which of the mass, rotational inertia and center of mass use authored values instead of being calculated from the attached shapes.

Added: Added a "PhysicsEvents.WorldTransformPlaneChange" event which is called when a PhysicsWorld transform plane is changed.

Added: Added a batch overload of "SetOwnerUserData()" to PhysicsShape, PhysicsBody, and PhysicsJoint.

Added: Added a selectedDrawing property to PhysicsBody, PhysicsShape and PhysicsJoint, batch SetSelectedDrawing methods, and PhysicsWorld.ClearDrawSelected, so individual objects can be drawn persistently when the world is drawn.

Added: Added a static PhysicsWorld.DrawShapes method that draws a span of shapes into their worlds.

Added: Added an autoAxis option to the slider and wheel joint definitions that derives the joint axis from the joint anchors when the joint is created.

Added: Added an extension method to "NativeArray<T>" of "Filter()", providing a lazy, allocation-free, Burst-compatible filtered view over physics result arrays (object creation, queries, events, and other operations). We've added a "IPhysicsResultFilter<T>" and "PhysicsResultEnumerable<T, TFilter>" to allow custom filter methods to be used.

Added: Added an owner key overload to PhysicsShape "DestroyBatch()", PhysicsBody "DestroyBatch()", and PhysicsJoint "DestroyBatch()", plus their PhysicsWorld "DestroyShapeBatch()"/"DestroyBodyBatch()"/"DestroyJointBatch()" equivalents.

Added: Added an owner overload to PhysicsShape "CreateShapeBatch()" and PhysicsBody "CreateBatch()", plus the PhysicsWorld "CreateBodyBatch()" equivalent.

Added: Added batch setters for user data, owner user data, contact filter and surface material on PhysicsShape, PhysicsBody and PhysicsJoint.

Added: Added the PhysicsCallbacks.IPreContactCallback and PhysicsCallbacks.IPreContinuousCallback interfaces for physics shapes, replacing PhysicsCallbacks.IPreSolveCallback which is now deprecated. IPreContactCallback reports a contact before it is solved and gives you the full contact manifold to modify or cancel. IPreContinuousCallback reports a fast moving shape that is about to be stopped short of another shape, and lets you decide whether to stop it. IPreSolveCallback previously reported both of these situations through a single callback. The per shape option that enables them is now called Pre Contact Callbacks.

Added: Added autoAnchorA and autoAnchorB properties to PhysicsJoint and PhysicsJointDefinition.

Added: Added autoDistance property to PhysicsDistanceJoint and PhysicsDistanceJointDefinition.

Added: Added PhysicsWorld.drawAtTransform and PhysicsWorldDefinition.drawAtTransform to draw bodies, shapes, and joints at their assigned Transform's pose instead of their simulated physics pose.

Added: Added PhysicsWorld.ExplosionDefinition.useTriggers to control whether an explosion applies an impulse to trigger shapes.

Added: Added PhysicsWorld.minEdgeLength, PhysicsWorld.minPolygonEdgeLength, and PhysicsWorld.minPolygonCollinearDistance to expose geometry validity thresholds, and an areEdgesValid property to SegmentGeometry, CapsuleGeometry, ChainSegmentGeometry, and PolygonGeometry to check a geometry's edges against them.

Added: Added PhysicsWorld.stateHash, which returns a hash of the current state of the world. Use it to compare the state of two worlds, for example when checking that a simulation is deterministic. The value is recalculated over the whole world each time you read it, so avoid reading it every frame.

Added: Added PhysicsWorld SetName() and GetName() methods to allow assigning of a 64 character name to help with world identity during debugging.

Added: Added pointA and pointB to the physics contact manifold point, which give the contact point on each shape in world space. The existing point property is now deprecated because the two new properties replace it.

Added: Added: "PhysicsMath.TryGetRelativeMatrix2D()" and "PhysicsMath.TryGetPlaneMatrix2D()", which compute a 2D relative transform without ever returning a NaN result for a degenerate or flattened scale. These are often required when authoring components and help calculate relative transformation between two in a Transform hierarchy.

Added: Added: PhysicsBody, PhysicsShape and PhysicsJoint now each have a "drawTarget" property, selecting which Unity editor views (Scene view, Game view or both) the object is drawn into when the world is drawn.

Changed: The batch and span setters on "PhysicsBody", "PhysicsShape" and "PhysicsJoint", along with "PhysicsWorld.Simulate", "PhysicsWorld.DrawShapes", "PhysicsSpace.SetBatchProxyAABB" and "PhysicsSpace.SetBatchProxyCategories", now return the number of items ignored because they were invalid and log a single warning when any are ignored.

Deprecated: Deprecated the PhysicsCallbacks.IPreSolveCallback interface. It reported both an existing contact and a predicted stop for a fast moving shape through a single callback, so it is replaced by PhysicsCallbacks.IPreContactCallback and PhysicsCallbacks.IPreContinuousCallback, one for each situation. The deprecated interface keeps working and still reports both, and a shape only uses it where the matching new interface is not implemented, so you can move over one at a time.

Deprecated: Deprecated PhysicsWorld.WorldProfile.applyBounciness; bounciness is no longer a separate solver stage so it always reads as zero.

Obsoleted: Removed PhysicsWorld and PhysicsWorldDefinition autoContactCallbacks and autoTriggerCallbacks properties as they are no longer required or used. The contact and trigger events are effectively free now and production of such events is still controlled on a per-shape basis so no behaviour has been lost.

Obsoleted: Obsoleted Playable APIs Playable.SetDelay, Playable.GetDelay, as well as Playable.SetPlayState. The delay functionality can be implemented manually via ScriptPlayables, either by inserting a new playable in the chain which implements the delay, or by modifying the parent playable to handle the delay.

Changed: Added an optional Display Name property to ProfilerCounterDescriptor for improved readability.

Added: Implemented visibility, focus and resizability APIs for Windowing.

Added: Implemented window focus, visibility, and destruction event system APIs in Windowing.

Added: Added CoreCLR ScriptingImplementation enum value exposing CoreCLR player support.

Added: Added the IVariantSelector interface, which you can implement to define custom variants for the localization system.

Added: New public API, Detach(node) and DetachChildren(node) on Hierarchy and HierarchyCommandList. A detached node keeps its data map entry but is unreachable from Root.

Added: New public API, IHierarchyNodeTypeHandlerViewModelState, and GetOrCreateHandlerState<T>, TryGetHandlerState<T> and DestroyHandlerState on HierarchyViewModel, for node type handler state that belongs to a single view model. HierarchyNodeTypeHandlerBase.SearchBegin, SearchMatch and SearchEnd gained overloads taking the HierarchyViewModel running the search.

Added: [Scripting] IL2CPP code coverage support.

Deprecated: Deprecated PlayerSettings.gpuSkinning. Use PlayerSettings.meshDeformation instead.

Deprecated: HierarchyNodeTypeHandlerBase.SearchBegin(HierarchySearchQueryDescriptor), SearchMatch(in HierarchyNode) and SearchEnd() are obsolete. Use the overloads that take a HierarchyViewModel, since handlers are shared by every view model on a hierarchy.
