Release Notes

All notable changes to this project will be documented in this file.

[Physics Samples Project for 1.3.0]

Changes

  • Added demo scene Modify Collider Geometry.unity demonstrating runtime collider deformations. In the demo, the geometry of various types of colliders are modified via the new ColliderBakeTransformAuthoring component, which lets you create cyclic animations during which a game object's collider and its visuals are deformed over time. This is achieved through use of the Collider.BakeTransform function, which applies an affine transformation to a collider, correspondingly rotating, translating, scaling and shearing its geometry in the process.
  • Added support for spring and damping for motors in the custom authoring components. In the motor demos, these fields are used now.
  • Demo scenes with motors now have examples of how to author using built-in components or custom components

Fixes

  • Modify Runtime - Collision Filter demo: fixed a bug where the render mesh of the cubes was being incorrectly changed to a sphere.
  • Fixed a memory leak in the ColliderBakeTransformSystem caused by the subscene being disposed before the OnDestroy could properly dispose a collider blob

[Physics Samples Project for 1.2.0]

Changes

  • Reorganized the samples, with cleanup of various samples' code and scenes.
  • Added demo scene Modify Collider Geometry.unity demonstrating runtime collider deformations. In the demo, the geometry of various types of colliders are modified via the new ColliderBakeTransformAuthoring component, which lets you create cyclic animations during which a game object's collider and its visuals are deformed over time. This is achieved through use of the Collider.BakeTransform function, which applies an affine transformation to a collider, correspondingly rotating, translating, scaling and shearing its geometry in the process.
  • Added support for spring and damping for motors in the custom authoring components. In the motor demos, these fields are used now.

[Physics Samples Project for 1.1.0]

Changes

  • Added demo scene 4e. Single Ragdoll with a GameObject ragdoll created using the built-in physics Ragdoll Wizard and simulated using Unity Physics for DOTS on one side and the built-in GameObject physics on the other.
  • Added demo scene 5m. Collider Modifications to show how to create mesh colliders during runtime
  • Added new API for BlobAssetReference MeshCollider.Create(UnityEngine.Mesh, CollisionFilter, Material) in Physics_MeshCollider.cs
  • Added new API for BlobAssetReference MeshCollider.Create(UnityEngine.Mesh.MeshData, CollisionFilter, Material) in Physics_MeshCollider.cs
  • Added new API for BlobAssetReference MeshCollider.Create(UnityEngine.Mesh.MeshDataArray, CollisionFilter, Material) in Physics_MeshCollider.cs
  • Renamed the 4d. Ragdoll scene to 4d. Ragdolls for clarity.
  • The Mouse Hover Authoring component was improved and now works also when hovering over physics entities whose rendering components are located in a child entity. Consequently, the previously disabled Mouse Hover Authoring component has now been enabled in the 4d. Ragdolls scene.
  • Added new physics component: Force Unique Collider Authoring to allow built-in colliders to be made unique during baking
  • Updated the 5b. Change Box Collider Size scene to use the new Physics Force Unique Collider component
  • The 5. Modify section now has a new section called 5g. Runtime Collider Modifications.
  • A new demo has been added: 5g1. Change Collider Material - Bouncy Boxes. This demo instantiates prefabs containing unique colliders and modifies collider blob data during runtime
  • The previously named 5g. Change Collider Filter demo has been renamed to 5g2. Unique Collider Blob Sharing. The focus of this demo is how collider data is shared, rather than how the CollisionFilter is modified.
  • The 5g2. Unique Collider Blob Sharing demo uses the new MakeUnique method in SpawnExplosionAuthoring.cs. The manual management of new colliders is no longer necessary.
  • Moved the 5m. Collider Modification demo to the 5g. Runtime Collider Modifications section and renamed it to 5g3. Runtime Collider Creation
  • Extended the Motion Properties - Mass demo with an additional seesaw created using built-in physics authoring components (in grey) alongside the already existing seesaw that uses custom physics authoring components (in yellow).
  • A new demo has been added: 5g4. Runtime Collision Filter Modification. This demo shows how to modify a CollisionFilter during runtime.

Fixes

  • Improved system start-up efficiency by not initializing systems that aren't required in the following files:
    • Tests/Animation/Scripts/AnimationPhysicsSystem.cs
    • Tests/MultipleWorlds/ClientServer/Scripts/ServerPhysicsSystem.cs
    • Tests/MultipleWorlds/CustomPhysicsGroup/MultiWorldMousePicker.cs
    • Tests/MultipleWorlds/CustomPhysicsGroup/UserWorldCreator.cs
  • Tests/SamplesTest/CreatePhysicsPerformanceTests.unity: Fixed an index out of range bug in the OnUpdate method of the system
  • Fixed bug in demo scene 5c. Change Collider Type where the collider type wasn't being updated'
  • Fixed bug in QueryTester.cs, which is used in demos 3a. All Hits Distance Test / 3b. Cast Test / 3c. Closest Hit Distance Test, where debug draw lines were not drawing the results of the queries. Any system using drawing features of the PhysicsDebugDisplaySystem must update this system within the PhysicsDebugDisplayGroup.

[Physics Samples Project for 1.0.0]

  • Added automatic import of Custom Physics Authoring experience:
    The custom physics authoring experience, built around the PhysicsBodyAuthoring and PhysicsShapeAuthoring components, is no longer embedded in the Unity Physics package API. Instead it is provided as a Unity Physics package sample called Custom Physics Authoring. This sample is now automatically imported into the PhysicsSamples project under Assets/Samples/Unity Physics/<package version>/Custom Physics Authoring. If you want to update the Unity Physics package in the PhysicsSamples project make sure to import the new version of this sample using the Package Manager under the Samples tab after the update and then delete the previous version of this sample from the project.

[Physics Samples Project for 0.10.0-preview] - 2021-12-31

Changes

  • Added ImmediatePhysicsWorldStepper utility class for running physics simulation immediately on the current thread.
  • Changed ProjectIntoFutureOnCueSystem in Pool demo to use ImmediatePhysicsWorldStepper.
  • Added Assets/Tests/MultipleWorlds/Animation/Animation scene that shows how you can use a separate PhysicsWorld to simulate a small number of non-critical bodies for animation purposes (character's ponytail and scabbard). DriveAnimationBodySystem syncs critical bodies between default and side physics world (character's head and torso) and prepares the data for non-critical bodies (position and velocity correction for ponytail and scabbard). AnimationPhysicsSystem performs single-threaded PhysicsWorld building, simulation and export to ECS components. The demo shows 2 variants of physically animated ponytail: with position and velocity corrections (green) and without them (blue).
  • Added Assets/Tests/MultipleWorlds/ClientServer/ClientServer scene as a simplified client-server sample, with game-critical ghost bodies (exist on both server and client) and client-only bodies that are simulated only locally to add to game's visual appeal. Bodies in server physics world are simulated first (would be predicted based on server data in real use-cases) and then mirrored into the default physics world. Default physics world contains ghost and client-only bodies, where ghost bodies are driven by their server counterparts (game objects are linked via Server Entity setting in Drive Ghost Body Authoring script). DriveGhostBodySystem drives ghost bodies by position or velocity, the ratio (position vs velocity) is determined by First Order Gain setting in Drive Ghost Body Authoring script on the client ghost body game object. ServerPhysicsSystem is the key system that builds, simulates and exports server physics world. The demo shows different kinematic bars (client-only, dynamic and kinematic ghost) rotating and pushing various speheres around (client-only, dynamic and kinematic ghosts driven by position, velocity and both equally).

  • Refactored the CollisionEvent and TriggerEvent demos to make the Stateful events clearer.

    • To add stateful events to your own project copy all scripts from the Stateful folder.
    • Then, if you want to have collision events:
      1. Use the 'Collide Raise Collision Events' option of the 'Collision Response' property of a PhysicsShapeAuthoring component, and
      2. Add a StatefulCollisionEventBufferAuthoring component to that entity (and select if details should be calculated or not)
      3. At runtime, read from the dynamic buffer of StatefulCollisionEvents
    • Alternatively, if you want to have trigger events:
      1. Use the 'Raise Trigger Events' option of the 'Collision Response' property of a PhysicsShapeAuthoring component, and
      2. Add a StatefulTriggerEventBufferAuthoring component to that entity
      3. At runtime, read from the dynamic buffer of StatefulTriggerEvents

[Physics Samples Project for 0.7.0-preview.3] - 2021-02-24

Changes

  • Dependencies

    • Updated Data Flow Graph from 0.18.0-preview.3 to 0.20.0-preview.4

  • Added Tests/VelocityClipping/VelocityClippingStacking demo to showcase a simple replacement for the removed SimulationCallbacks.Phase.PostSolveJacobians. This demo does a really simple velocity clipping and the point is not to showcase stacking (which is covered with Tests/Stacking demos) but instead to show how to achieve the effect similar to previous callback without using the callback itself.

  • Added Tests/SystemScheduling/SchedulingSample which shows how jobs that interact with physics runtime data (stored in PhysicsWorld) should be scheduled.

Fixes

  • Fixed a bug where duplicate joint Entities were created when multiple joint components are added to the same game object.
