Timeline

A Timeline is an object with keyframes, markers, and a timer. The timer updates the Timeline every time it's updated. Typically a Timeline has a set duration for synching/combining animations.

Playmodes

• once - Plays the Timeline once, then pauses the timeline
• loop - Keeps replaying the Timeline until timesPlayed reaches maxPlays
• pingPong - Plays the Timeline forwards and backwards

Keyframe

A Keyframe is an object that interpolates between 2 Arrays, startValue and endValue. autoOrigin is used when a keyframe's startValue doesn't equal the object's current value when it begins.

Types

• linear - Linear interpolation from A to B
• bezier - Cubic Bezier interpolation from A to B
• hold - No interpolation from A to B until the Keyframe is complete

Marker

A Marker is time-based label with optional commands. Current built-in actions are 'stop', which stops the timeline, and 'delay', which will pause the timeline for the set duration.

Jumps to the "idle" Marker timeline.goToMarker( "idle" );

Commands

"stop" - Stops the Timeline

Stop the Timeline at 1 second

timeline.addMarker( new Marker("Idle", 1.0, "stop") );
