Classes

A singleton configuration class for MotionMachine.

Contains a value as a weak reference to an object

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. A single MotionGroup could hold Motion, PhysicsMotion, and PathMotion objects, and even other MoveableCollection objects. The MotionGroup class is a good solution when you want to easily synchronize the movements of many Moveable objects.

MotionSequence moves a collection of objects conforming to the Moveable protocol in sequential order. A single MotionSequence could hold Motion, PhysicsMotion, and PathMotion objects, and even other MoveableCollection objects. 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.

This class represents a single property and information about the state of its value interpolation, as well as metadata such as the KeyPath which allows a motion class to get and set these values.

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

DisplayLinkTempo chooses the appropriate TempoProviding class to send tempo updates that are synchronized with the refresh rate of the display. On Mac, the MacDisplayLinkTempo class is used, and on other platforms the CATempo class is used. Both classes use CADisplayLink.

This class uses a CADisplayLink object to send out tempo updates that are synchronized with the refresh rate of the currently-active Mac display.

TimerTempo uses an internal DispatchSourceTimer object to send out tempo updates. By default, the update interval is twice the maximum refresh rate of the current display.

CGColorAssistant provides support for the CGColor type.

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.

NumericAssistant provides support for top-level properties on the target object which are numeric values. This class supports all numeric types which conform to either BinaryFloatingPoint or BinaryInteger, as well as NSNumber.

SIMDAssistant provides support for all current SIMD types.

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.
