majiayu000 Universal Animation Solutions
A complete diagnostic framework using all 12 Disney principles.
The 12 Principles Checklist
Run through each principle to diagnose any animation problem:
1. Squash and Stretch
Check: Is there appropriate flexibility? Problem sign: Rigid, lifeless motion Fix: Add subtle scale changes on impact/acceleration
2. Anticipation
Check: Is there buildup before action? Problem sign: Actions feel sudden or surprising Fix: Add small reverse movement or wind-up
3. Staging
Check: Is the important thing clear? Problem sign: Users miss key information Fix: Isolate animated element, reduce competing motion
4. Straight Ahead vs Pose-to-Pose
Check: Is the approach right for the effect? Problem sign: Uncontrolled or too rigid motion Fix: Use keyframes for UI; frame-by-frame for organic
5. Follow Through
Check: Do things settle naturally? Problem sign: Abrupt, mechanical endings Fix: Add overshoot and settle, or soft deceleration
6. Slow In and Slow Out
Check: Is there proper easing? Problem sign: Robotic, linear motion Fix: Apply ease-out for entrances, ease-in for exits
7. Arcs
Check: Is the motion path natural? Problem sign: Unnatural straight-line movement Fix: Add curved paths for organic motion
8. Secondary Action
Check: Do supporting elements enhance? Problem sign: Flat, one-dimensional animation Fix: Add subtle complementary movements
9. Timing
Check: Is the speed appropriate? Problem sign: Too fast or too slow Fix: Micro: 100-200ms, Transitions: 200-400ms
10. Exaggeration
Check: Is the drama level right? Problem sign: Too subtle or too dramatic Fix: Match exaggeration to context importance
11. Solid Drawing
Check: Is rendering correct? Problem sign: Visual glitches, distortion Fix: Use transform/opacity only, check GPU layers
12. Appeal
Check: Does it feel right? Problem sign: Hard to articulate wrongness Fix: Align motion with brand/emotional intent
Quick Diagnostic
- Describe the problem in one sentence
- Identify which principle relates most directly
- Check adjacent principles (problems cluster)
- Apply targeted fix from that principle
Master Troubleshooting Checklist
- Does animation serve a purpose?
- Is timing appropriate (usually 150-300ms)?
- Is easing applied (not linear)?
- Does it respect
prefers-reduced-motion? - Is only transform/opacity being animated?
- Is motion guiding attention correctly?
- Does it match brand/emotional context?
- Can users complete tasks without it?
- Test on slowest target device
- Get user feedback with emotional vocabulary
When to Remove Animation
Remove animation entirely if:
- It doesn't serve clear purpose
- Users complain or skip it
- It delays task completion
- It causes accessibility issues
- Performance is unacceptable
- You can't articulate why it exists
