# Lottie Animation Principles
|
||||
|
||||
Implement all 12 Disney animation principles using Lottie (Bodymovin) for vector animations.
|
||||
|
||||
## 1. Squash and Stretch
|
||||
|
||||
In After Effects before export:
|
||||
- Animate Scale X and Y inversely
|
||||
- Use expression: `s = transform.scale[1]; [100 + (100-s), s]`
|
||||
|
||||
```javascript
|
||||
// Control at runtime
|
||||
lottie.setSpeed(1.5); // affect squash timing
|
||||
```
|
||||
|
||||
## 2. Anticipation
|
||||
|
||||
Structure your AE composition:
|
||||
1. **Frames 0-10**: Wind-up pose
|
||||
2. **Frames 10-40**: Main action
|
||||
3. **Frames 40-50**: Settle
|
||||
|
||||
```javascript
|
||||
// Play anticipation segment
|
||||
anim.playSegments([0, 10], true);
|
||||
setTimeout(() => anim.playSegments([10, 50], true), 200);
|
||||
```
|
||||
|
||||
## 3. Staging
|
||||
|
||||
```javascript
|
||||
// Layer multiple Lotties
|
||||
<div className="scene">
|
||||
<Lottie animationData={background} style={{ opacity: 0.6 }} />
|
||||
<Lottie animationData={hero} style={{ zIndex: 10 }} />
|
||||
</div>
|
||||
```
|
||||
|
||||
## 4. Straight Ahead / Pose to Pose
|
||||
|
||||
Pose to pose in AE:
|
||||
- Set keyframes at key poses
|
||||
- Let AE interpolate between
|
||||
- Use Easy Ease for smoothing
|
||||
|
||||
```javascript
|
||||
// Jump to specific poses
|
||||
anim.goToAndStop(25, true); // frame 25
|
||||
```
|
||||
|
||||
## 5. Follow Through and Overlapping Action
|
||||
|
||||
In After Effects:
|
||||
- Offset child layer keyframes by 2-4 frames
|
||||
- Use parenting with delayed expressions
|
||||
- `thisComp.layer("Parent").transform.position.valueAtTime(time - 0.05)`
|
||||
|
||||
## 6. Slow In and Slow Out
|
||||
|
||||
AE Keyframe settings:
|
||||
- Select keyframes > Easy Ease (F9)
|
||||
- Use Graph Editor to adjust curves
|
||||
- Bezier handles control acceleration
|
||||
|
||||
```javascript
|
||||
// Adjust playback speed dynamically
|
||||
anim.setSpeed(0.5); // slower
|
||||
anim.setSpeed(2); // faster
|
||||
```
|
||||
|
||||
## 7. Arc
|
||||
|
||||
In After Effects:
|
||||
- Use motion paths (position property)
|
||||
- Convert keyframes to Bezier
|
||||
- Pull handles to create arcs
|
||||
- Or use "Auto-Orient to Path"
|
||||
|
||||
## 8. Secondary Action
|
||||
|
||||
```javascript
|
||||
// Trigger secondary animation
|
||||
mainAnim.addEventListener('complete', () => {
|
||||
secondaryAnim.play();
|
||||
});
|
||||
|
||||
// Or sync with frame
|
||||
mainAnim.addEventListener('enterFrame', (e) => {
|
||||
if (e.currentTime > 15) particleAnim.play();
|
||||
});
|
||||
```
|
||||
|
||||
## 9. Timing
|
||||
|
||||
```javascript
|
||||
anim.setSpeed(0.5); // half speed - dramatic
|
||||
anim.setSpeed(1); // normal
|
||||
anim.setSpeed(2); // double speed - snappy
|
||||
|
||||
// Or control frame rate in AE export
|
||||
// 24fps = cinematic, 30fps = smooth, 60fps = fluid
|
||||
```
|
||||
|
||||
## 10. Exaggeration
|
||||
|
||||
In After Effects:
|
||||
- Push scale beyond 100% (120-150%)
|
||||
- Overshoot rotation
|
||||
- Use Overshoot expression
|
||||
- `amp = 15; freq = 3; decay = 5; n = 0; time_start = key(1).time; if (time > time_start) { n = (time - time_start) / thisComp.frameDuration; amp * Math.sin(freq*n) / Math.exp(decay*n/100); } else { 0; }`
|
||||
|
||||
## 11. Solid Drawing
|
||||
|
||||
In After Effects:
|
||||
- Use 3D layers
|
||||
- Apply perspective camera
|
||||
- Animate Z position and rotation
|
||||
- Use depth of field
|
||||
|
||||
## 12. Appeal
|
||||
|
||||
Design principles in AE:
|
||||
- Smooth curves over sharp angles
|
||||
- Consistent timing patterns
|
||||
- Pleasing color palette
|
||||
- Clean vector shapes
|
||||
|
||||
```javascript
|
||||
// React Lottie with hover
|
||||
<Lottie
|
||||
animationData={data}
|
||||
onMouseEnter={() => anim.setDirection(1)}
|
||||
onMouseLeave={() => anim.setDirection(-1)}
|
||||
/>
|
||||
```
|
||||
|
||||
## Lottie Implementation
|
||||
|
||||
```javascript
|
||||
import Lottie from 'lottie-react';
|
||||
import animationData from './animation.json';
|
||||
|
||||
<Lottie
|
||||
animationData={animationData}
|
||||
loop={true}
|
||||
autoplay={true}
|
||||
style={{ width: 200, height: 200 }}
|
||||
/>
|
||||
```
|
||||
|
||||
## Key Lottie Features
|
||||
|
||||
- `playSegments([start, end])` - Play frame range
|
||||
- `setSpeed(n)` - Control timing
|
||||
- `setDirection(1/-1)` - Forward/reverse
|
||||
- `goToAndStop(frame)` - Pose control
|
||||
- `addEventListener` - Frame events
|
||||
- Interactivity via `lottie-interactivity`
