PMTween Versions Save

• PMTweenPhysicsSystem (used internally by PMTweenPhysicsUnit) now uses a fixed timestep, which though rudimentary, helps smooth out tween value jittering
• Fixed bug with physics timer not properly removed

• PMTweenPhysicsUnit now updates its physics system independently of property updates, at a frequency of 120 fps by default (to provide double the resolution of a normal 60fps app). This can be changed by PMTweenPhysicsUnit's new property physicsTimerInterval.
• PMTweenPhysicsSystem now handles friction values with less accumulated error.
• PMTweenPhysicsUnit's velocity is now expressed in units per second. Prior to this the velocity acted as units per frame, which obviously caused inconsistent simulations.

• Updated project architecture to use single header import
• Fixed string equality check in PMTweenSupport when comparing keyPaths
• Miscellaneous project cleanup

• Added support for CGVector structs as property tweening targets.
• Added support for tvOS as a target.
• Updated init methods to use instancetype
• Changed minimum iOS target to 7.0.

• Implemented additive animation in PMTweenUnit! • Updated PMTweenObjectUpdater to provide additive updating support. • Updated tests. • Updated Examples project to include additive demos.

• Fixed multiple tweens targeting same object property incorrectly overriding initial value of first tween.

• Fixed PMTweenUnit and PMTweenPhysicsUnit failing to tween object properties specified by a single-element keyPath. • Fixed NSNumber object properties with a nil value not tweening. Such properties are now initialized with the specified starting value during the init method. • Changed all init methods to return instancetype instead of id. • More tests.

• Added PMTweenPhysicsUnit and PMTweenPhysicsSystem classes to provide dynamic, physics-based tweening! PMTweenPhysicsUnit adopts PMTweening, so you get all the standard PMTween functionality – use it in groups and sequences, add reversing, pause it, etc. See the documentation and examples project for more info.
• Fixed bug where PMTweening classes set to reversing wouldn't reverse properly inside a PMTweenGroup that wasn't itself reversing.
• currentValue property wasn't being set to startingValue in PMTweenUnit on setup.
• New tests.
• Updated examples project.

• PMTweenBeat: Fixed this class not having a default tempo or setting child tween tempos to nil.
• PMTweenGroup: Base init method was not calling setTempo.
