Classes

Motion handles a single motion operation on one or more properties, interpolating between specified starting and ending values.

MotionGroup handles the movement of one or more objects which conform to the Moveable protocol, either being instances of Motion or other custom classes. The MotionGroup class is a good solution when you want to easily synchronize the movements of many Moveable objects.

A singleton configuration class for MotionMachine.

MotionSequence moves a collection of objects conforming to the Moveable protocol in sequential order. MotionSequence provides a powerful and easy way of chaining together individual motions to create complex animations.

PathMotion handles a single motion operation of a coordinate point along a CGPath. It does not directly accept PropertyData objects, but instead transforms a value between 0.0 and 1.0, representing the length of the associated path. Using this value, it updates the current point on the path.

PathPhysicsMotion handles a single motion operation of a coordinate point along a CGPath using a physics system to update the value with a decaying velocity. It does not directly accept PropertyData objects, but instead transforms a value between 0.0 and 1.0, representing the length of the associated path. Using this value, it updates the current point on the path.

This state object is used in conjunction with PathMotion to handle the movement of a point along a path.

PhysicsMotion handles a single motion operation on one or more properties, using a physics system to update values with decaying velocity.

A simple physics engine used with PhysicsMotion and PathPhysicsMotion to calculate values for motions. It primarily uses a constant velocity, plus a friction component, to update movements of values over time. As of version 2.2.0 it also supports simple collision handling between two optional fixed start and end points, and a restitution value to control the value’s elasticity when colliding.

CATempo uses a CADisplayLink object to send out tempo updates that are synchronized with the refresh rate of the display on iOS.

Tempo is an abstract class that provides a basic structure for sending update beats. Moveable classes use these beats to calculate new motion interpolation values. Concrete subclasses should call tempoBeatUpdate with incremental timestamps as necessary.

TimerTempo uses an internal NSTimer object to send out tempo updates.

CGStructAssistant provides support for several Core Graphics struct types, including CGPoint, CGSize, CGRect, CGVector, CGAffineTransform, as well as QuartzCore’s CATransform3D type. It also provides support for the NSNumber type.

CIColorAssistant provides support for Core Image’s CIColor type.

UIColorAssistant provides support for the UIColor type.

UIKitStructAssistant provides support for the UIKit structs UIEdgeInsets and UIOffset.

The ValueAssistantGroup class enables multiple ValueAssistant objects to be attached to a single motion class.
