Unity 2020 Support

This release of UnityModules adds support for Unity 2020.1!

Changelog

• Add support for Unity 2020.1

Note for 2020.1 users:
If you get errors related to "SpatialTracking" upon importing the Core module, you need to install the Oculus XR package, which adds the necessary XR dependency.

Only the Core and Graphic Renderer packages have been modified from 4.5.0. For completeness' sake, all of the main modules are included in this release.

Community contributions

• Added the LeapCSharp assembly definition file! - @StephenHodgson

  Thank you for your contribution!

With love from the UnityModules team,

We're changing to a unified release model

This release reflects a slight deviation from how we've done UnityModules releases in the past. To make it easier to get releases out the door, we're unifying the versioning system around the "Core Asset" release, and combining modules together into a single release version. Individual module packages are still available, but this path is essentially a roundabout way to copy files into your project, which you can do straight from the repo, now considered the central source of truth on master.

Changelog

• Moves the LeapMotion folder from Assets to Assets/Plugins. This shortens project build times.
• Upgrades the default Unity version to 2019.2.
• Aims to support Unity 2017.1 through 2019.3. Please submit a ticket if you experience issues using UnityModules with any Unity versions beyond 2017.1.
• Fixes an issue that prevented hands from rendering when using Scriptable Render Pipeline projects.
• Adds a desktop-mode IE example scene.

Hotfixes (2020-05-01):

• Fixes compilation errors in 2018.4.
• Note that the SRP is Experimental in 2018.4 and lacks the correct callbacks to support hand timewarping. As a consequence, hand rendering is not compatible with the SRP in 2018.4.
• Fixes compilation warnings in 2019.3.

Community contributions

• Adds a configuration option to IE two-handed grasps. - @DerSticher

• Adds an event on initial IE contact bone creation. - @SyDroX

  Thank you for your contributions!

Requires: Core Asset 4.4.0 & Leap Motion Orion 4.0.0

What's New:

General

• Added the IgnoreCollidersForInteraction component, which causes a Collider to be ignored by the Interaction Engine. This is intended for trigger colliders that should be considered only for raycasting and not, e.g., for grasping or collision.

• Removed the (unused and deprecated) RigidbodyWarper script.

• VR controllers will now be detected at runtime in the IE example scenes that support them. (Previously, they had to be active and visible to Unity as soon as the application started running.) This functionality causes a minimal amount of garbage allocation every few seconds in those scenes, but did not have a noticeable impact on garbage collection times. You can disable this functionality by disabling "pollConnection" on the InteractionXRController script.

Grasping

• Improved the ability to grasp small objects.

• Improved the consistency of grasping an object that was held by the other hand.

• Added OnGraspBegin, OnGraspStay, and OnGraspEnd callbacks to InteractionController.

UI

• Modified the Basic UI example scene to demonstrate how a InteractionButton UI panel can be moved without causing the attached physical buttons to wobble.

Curved Space Support

• Fixed a bug where Interaction Objects inherited LeapSpace components that were only used for an object's LeapGraphics. InteractionBehaviour now only considers any LeapSpaces -- such as LeapCylindricalSpace or LeapSphericalSpaces -- that are on or the parent of a Collider.

Requires: Core Asset 4.4.0 & Leap Motion 4.0.0

What's New:

• If you are upgrading a project using the Graphic Renderer from 2017.3 to 2017.4, you may experience a crash when opening certain scenes. This is due to sprite library data incompatibility and can be resolved by deleting your Temp and Library folders and re-opening Unity.

• Fixed an issue where graphics in Dynamic or Text groups would cause MissingReferenceExceptions when deleted. Note that you cannot delete (or add) graphics in Baked groups, although you can disable them.

• Fixed an issue where tints and vertex colors were not correctly converted to linear space when the application was targeting linear space rendering.

• Incremental bugfixes for stability.

Requires Core Asset 4.4.0 & Leap Motion Orion 4.0.0

What's New:

• Fixed an issue where RiggedHand would occasionally raise a LookRotation error.

• Added an option for Rigged Hands to scale their last fingerbones, which allows rigged hands to achieve correct fingertip positions when tracked hands do not precisely match the scale of the model the hand was rigged on.

Requires: Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3
• Added ability to force a controller to grasp an object
• Fix a bug where the physics representation of the hands would explode sometimes when switching between curved spaces
• Added the SwapGrasp function and a corresponding example scene, allowing you swap a grasped object with another object in the scene.
• Correctly account for the Physics.autoSyncTransforms state during the Interaction Manager update.

Requires: Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3
• Allowed you to disable or enable a graphic without detaching or re-attaching the graphic.
• Disabled graphics are no longer visible!
• Disabling and Enabling graphics is now lightning fast!
• Improved dirty detection to reduce rebuild situations
• Fixed several edge cases

Requires Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3
• Renamed IHandModel to HandModelBase

Requires Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3

Requires Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3

Requires Core Asset 4.3.4

What's New:

• Updated to support Unity 2017.3

Requires: Core Asset 4.3.0

What's New:

• Pressing X on initial gravity and timestep warnings no longer dismisses the warnings forever.
• Example 7 has been added, demonstrating how to set up a scene to support putting the player in a moving reference frame and still have user interfaces function properly.
• SceneSettings have been removed from Example 2, preventing project settings from getting clobbered.
• Sliders have had their inspectors organized more neatly.
• Fixed an issue where, at low physics timesteps, buttons moved too slowly.
• Interaction objects are no longer required to exist on the Interaction layer. Layers with interaction objects on them are tracked and still filtered for physics optimization.
• Interaction buttons and sliders can now be constructed based upon where they relax to or where they depress to.
• Added a warning when RigidRoundHand scripts are detected in the scene, as these scripts break proper physics functionality.
• Fixed physical and visual instability when grasping buttons.
• Fixed instability when grasping objects with centers of mass that are offset from the Rigidbody transform position.
• Interaction Controllers now provide warnings in their inspectors if they are added to a scene but not beneath an InteractionManager.
• Fixed exception when adding an InteractionBehaviour component at runtime
• Fixed a bug with AnchorableBehaviours where inspector utility buttons were incorrectly grayed out when only a single object was selected.

Requires: Core Asset 4.3.0

What's New:

• SetRuntimeTint now features a string-based overload taking in HTML color strings, allowing UnityEvents to target the method in the inspector.
• Graphics now prefer the group they were originally added to, better supporting scenarios where graphics are enabled or disabled at runtime.
• Fixed a bug where graphic settings were not duplicated properly when an entire Graphic Renderer was duplicated.
• Fixed a bug where text glyphs were not being refreshed properly.
• Added LeapBoxGraphic and LeapPanelOutlineGraphic alongside the LeapPanelGraphic as additional procedural mesh generators built-in to the Graphic Renderer.

Requires: Core Asset 4.2.1

What's New:

This is a hotfix release to address the following issues:

• Added warnings for improperly configured controller input settings
• Added warnings for improperly configured gravity settings
• Added warnings for improperly configured physics timestep settings

Requires: Core Asset 4.2.0 or 4.2.1

What's New:

• Efficiently render many meshes with a small number of draw calls.
• Control per-object properties easily and efficiently.
• Use curved spaces to bend and warp your objects.
• Designed specifically for high mobile performance.

Requires: Core Asset 4.2.0

What's New:

• Interact intuitively with physical objects in Unity, in VR
• Easily create stable, physical, 3D user interfaces
• Design interactive experiences around physical proximity to objects, grasping objects, or touching objects
• Supports hands and VR controllers equally well
