TouchScript

• Minimum Unity version: 4.5
• Fixed Windows Store publishing error due to missing List.AsReadOnly() method. (issue #105)
• Fixed Tap and LongPress gestures not working with timeScale = 0. (issue #100)
• Fixed possible division by 0 in ScaleGesture when two touches are exactly in the same position. (issue #97)

• Minimum Unity version: 4.5
• Updated editor interfaces for input sources, gestures and Touch Manager.
• Touch Manager inspector now properly reflects friendly gestures list (issue #52).
• Layers no longer register to TouchManager automatically to prevent sorting issues.
• Added Layers example.
• Removed TouchLayer.Camera. It's functionality should now be implemented with TouchLayer.WorldProjectionNormal + TouchLayer.ProjectTo.
• Renamed ProjectionType.Camera to ProjectionType.Layer.
• Fixed FullscreenLayer. It now works with all gestures.
• FullscreenTarget is now obsolete.
• All examples are now packaged with required DLLs to prevent confusion.

• Minimum Unity version: 4.5
• Added tags to touch points.
• Added PlayMaker actions for common gestures.
• Removed duplicated input sources from assemblies since Unity 4.5 fixes the bug with linked DLLs.
• Mouse or Mobile input is created automatically if there's no input in the scene.
• Gestures now reset cached screen positions.
• PanGesture now uses cached screen position.
• Gesture.IsFriendly(gesture) is now public.

• Added gesture hierarchy example.
• ITouch.Hit now returns correct information when touch point moves.
• Automatically disabling PressAndHold Windows gesture for Win7 and Win8 inputs.
• Added Fullscreen Layer as a workaround for issues #89, #90.
• TouchHitFactory is now public (issue #89).
• Fixed incorrect pan delta in Transformer2D.
• Optimized gesture logic.
• Various fixes to VS solutions and bash build scripts.

Updated:

• Core: TouchScript now supports UnityScript and SendMessage events.
• Core: TouchScript now extensively uses DPI to scale internal values in cm and tries to determine current display DPI automatically. If it's not possible you can specify DPI manually using DisplayDevice assets.
• Docs: Added a lot of comments and auto-generated docs to the code.
• Gestures: Gestures now have individual events (for example Tapped, Pressed, Released). This should make everything easier for newcomers.
• Gestures: TapGesture now supports single/double/tripple taps and fails if touch points moved more than DistanceLimit from initial touch.
• Gestures: You can now require another gesture to fail before a gesture can be recognized. For example, to handle single- and doubletap functionality on one object.
• Gestures: LongPressGesture now fails if touch points moved more than DistanceLimit from initial touch.
• Gestures: Setting TransformGesture.ProjectionNormal while Projection is set to Camera will reset it to Local mode.
• Hit: You can now disable HitTest components on game objects.
• Code: Refactored and restructured code to fit code guidelines.
• Code: Optimized internal classes for performance.
• Visual: TouchDebugger prefab now looks nicer ^_^
• Examples: Reworked all examples and added new ones.
• Scaleform: Changed Scaleform integration. Split code to ScaleformCamera and ScaleformLayer. Moved key to separate asset. Tested with the latest scaleform plugin (March 2014).
• Editor: All Gestures by default now have a standard custom inspector.
• Editor: Updated and improved all custom inspectors for bundled gestures.
• Editor: Gesture editors are now much more prefab friendly.
• Editor: Added toggles on input sources to disable if needed. For example, MouseInput disabling on mobile platforms.
• Editor: Moved advanced options to Advanced foldout.
• Mac: Added Mac post-build commands in Debug configuration.

Bug fixes:

• PanGesture now doesn't break if two touches happen to be in the same position (issue #64).
• Everything now works nicely with scene reloading.
• Gestures are now properly reset when disabled.
• 2D layers are now handled properly (issue #60, #81).
• Fixed a sorting bug when objects were in a container with RigidBody attached.
• Fixed NullPointerException for layers which might not returned a valid ITouchHit.
• Fixed Windows 8 touch position scaling (issue #85, #82).
• MouseInput now can disable itself on Windows Store platform.

Api changes:

• Most of the classes are now sealed and internal. API not intended to be used is hidden.
• Most framework classes now return IList instead of List.
• TouchPoint.InvalidPosition is renamed to INVALID_POSITION, Gesture.InvalidPosition is removed.
• Now all gestures have CombineTouchPoints property.
• Changed HitTest logic. Now all HitTest components on object must report HIT for touch to hit this object.
• All public APIs now use ITouch instead of TouchPoint. These objects must not be cached in any way since they might be reused.
• All public APIs now use ITouchHit instead of TouchHit. Moved 3d and 2d parameters to ITouchHit3D and ITouchHit2D. These objects must not be cached in any way since they might be reused.
• Renamed Cluster2 to Clusters. Moved some cluster recognition logic to ClusterUtils.
• Moved GestureStateChangeEventArgs to TouchScript.Gestures namespace.
• Moved TouchEventArgs to TouchScript namespace. Removed TouchScript.Events namespace.
• Updated MetaGesture API, renamed TouchPoint to Touch for consistency.
• Changed all occurrences of "touchpoint" to "touch" in API for consistency.
• Removed ClusterUtils.GetClusterCamera.
• Changed RotateGesture.LocalDeltaRotation to DeltaRotation, added RotationAxis.
• Moved IGestureDelegate to Gesture namespace.
• Moved Meta, Press and Release gestures to TouchScript.Gestures namespace from TouchScript.Gestures.Simple namespace.
• Removed unused properties from TouchHit2D and TouchHit3D.
• Clusters.MinPointsDistance is now 0 by default (was 1).
• Touch layers now return Miss if not enabled.

Library structure:

• Completely changed the folder structure of the library.
• All core TouchScript classes are in TouchScript folder.
• All inputs are in TouchScript.Inputs folder.
• All examples and platform specific projects are in UnityPackages folder.
• UnityPackage folder contains build scripts.

• Fixed a bug with Windows 7 touch in 32-bit apps.
• Added PressGesture/ReleaseGesture.IgnoreChildren flag to listen only to touch events on the object.
• Added TouchLayer.TouchBegan event.
• Fixed compile warnings.
