@ue-too/animate / CompositeAnimation

Class: CompositeAnimation

Defined in: composite-animation.ts:113

Container for sequencing and composing multiple animations.

Remarks

CompositeAnimation allows you to orchestrate complex animation sequences by:

• Sequencing: Add animations to play one after another
• Overlapping: Start animations before previous ones complete
• Synchronizing: Play multiple animations simultaneously
• Nesting: Compose animations contain other composite animations

Key Features

• Add animations at specific time offsets
• Position animations relative to other animations (addAnimationAfter, addAnimationBefore)
• Automatic duration calculation based on child animations
• Hierarchical composition for complex sequences
• Prevent cyclic animation dependencies

Example

Basic sequence

const sequence = new CompositeAnimation();

// Add first animation at start (time 0)
sequence.addAnimation('fadeIn', fadeAnimation, 0);

// Add second animation after first completes
sequence.addAnimationAfter('slideIn', slideAnimation, 'fadeIn');

// Add third animation to overlap with second (100ms after second starts)
sequence.addAnimationAdmist('scaleUp', scaleAnimation, 'slideIn', 100);

sequence.start();
