Popmotion Animation Principles

Popmotion动画原则

Implement all 12 Disney animation principles using Popmotion's composable animation functions.
使用Popmotion的可组合动画函数实现全部12条迪士尼动画原则。

1. Squash and Stretch

1. 挤压与拉伸

javascript
import { animate } from "popmotion";

animate({
  from: { scaleX: 1, scaleY: 1 },
  to: { scaleX: 1.2, scaleY: 0.8 },
  duration: 150,
  onUpdate: ({ scaleX, scaleY }) => {
    element.style.transform = `scaleX(${scaleX}) scaleY(${scaleY})`;
  }
});
javascript
import { animate } from "popmotion";

animate({
  from: { scaleX: 1, scaleY: 1 },
  to: { scaleX: 1.2, scaleY: 0.8 },
  duration: 150,
  onUpdate: ({ scaleX, scaleY }) => {
    element.style.transform = `scaleX(${scaleX}) scaleY(${scaleY})`;
  }
});

2. Anticipation

2. 预备动作

javascript
// Wind up then action
animate({
  from: 0,
  to: 10,
  duration: 200,
  onUpdate: v => element.style.transform = `translateY(${v}px) scaleY(0.9)`,
  onComplete: () => {
    animate({
      from: 10,
      to: -200,
      duration: 400,
      ease: easeOut,
      onUpdate: v => element.style.transform = `translateY(${v}px)`
    });
  }
});
javascript
// Wind up then action
animate({
  from: 0,
  to: 10,
  duration: 200,
  onUpdate: v => element.style.transform = `translateY(${v}px) scaleY(0.9)`,
  onComplete: () => {
    animate({
      from: 10,
      to: -200,
      duration: 400,
      ease: easeOut,
      onUpdate: v => element.style.transform = `translateY(${v}px)`
    });
  }
});

3. Staging

3. 舞台呈现

javascript
animate({
  from: 1,
  to: 0.6,
  onUpdate: v => bg.style.opacity = v
});
animate({
  from: 1,
  to: 1.1,
  onUpdate: v => hero.style.transform = `scale(${v})`
});
javascript
animate({
  from: 1,
  to: 0.6,
  onUpdate: v => bg.style.opacity = v
});
animate({
  from: 1,
  to: 1.1,
  onUpdate: v => hero.style.transform = `scale(${v})`
});

4. Straight Ahead / Pose to Pose

4. 逐帧动画/关键帧动画

javascript
import { keyframes } from "popmotion";

keyframes({
  values: [
    { x: 0, y: 0 },
    { x: 100, y: -50 },
    { x: 200, y: 0 },
    { x: 300, y: -30 }
  ],
  duration: 1000,
  onUpdate: ({ x, y }) => {
    element.style.transform = `translate(${x}px, ${y}px)`;
  }
});
javascript
import { keyframes } from "popmotion";

keyframes({
  values: [
    { x: 0, y: 0 },
    { x: 100, y: -50 },
    { x: 200, y: 0 },
    { x: 300, y: -30 }
  ],
  duration: 1000,
  onUpdate: ({ x, y }) => {
    element.style.transform = `translate(${x}px, ${y}px)`;
  }
});

5. Follow Through and Overlapping Action

5. 跟随动作与重叠动作

javascript
animate({ from: 0, to: 200, duration: 500,
  onUpdate: v => body.style.transform = `translateX(${v}px)` });

animate({ from: 0, to: 200, duration: 500, elapsed: -50, // delay
  onUpdate: v => hair.style.transform = `translateX(${v}px)` });

animate({ from: 0, to: 200, duration: 600, elapsed: -100,
  onUpdate: v => cape.style.transform = `translateX(${v}px)` });
javascript
animate({ from: 0, to: 200, duration: 500,
  onUpdate: v => body.style.transform = `translateX(${v}px)` });

animate({ from: 0, to: 200, duration: 500, elapsed: -50, // delay
  onUpdate: v => hair.style.transform = `translateX(${v}px)` });

animate({ from: 0, to: 200, duration: 600, elapsed: -100,
  onUpdate: v => cape.style.transform = `translateX(${v}px)` });

6. Slow In and Slow Out

6. 缓入缓出

javascript
import { animate, easeInOut, easeIn, easeOut } from "popmotion";

animate({
  from: 0,
  to: 300,
  duration: 600,
  ease: easeInOut,
  onUpdate: v => element.style.transform = `translateX(${v}px)`
});
javascript
import { animate, easeInOut, easeIn, easeOut } from "popmotion";

animate({
  from: 0,
  to: 300,
  duration: 600,
  ease: easeInOut,
  onUpdate: v => element.style.transform = `translateX(${v}px)`
});

7. Arc

7. 弧线运动

javascript
keyframes({
  values: [
    { x: 0, y: 0 },
    { x: 100, y: -100 },
    { x: 200, y: 0 }
  ],
  duration: 1000,
  ease: easeInOut,
  onUpdate: ({ x, y }) => {
    element.style.transform = `translate(${x}px, ${y}px)`;
  }
});
javascript
keyframes({
  values: [
    { x: 0, y: 0 },
    { x: 100, y: -100 },
    { x: 200, y: 0 }
  ],
  duration: 1000,
  ease: easeInOut,
  onUpdate: ({ x, y }) => {
    element.style.transform = `translate(${x}px, ${y}px)`;
  }
});

8. Secondary Action

8. 次要动作

javascript
// Primary action triggers secondary
animate({
  from: 1, to: 1.1, duration: 200,
  onUpdate: v => button.style.transform = `scale(${v})`,
  onComplete: () => {
    animate({
      from: 0, to: 15, duration: 150,
      onUpdate: v => icon.style.transform = `rotate(${v}deg)`
    });
  }
});
javascript
// Primary action triggers secondary
animate({
  from: 1, to: 1.1, duration: 200,
  onUpdate: v => button.style.transform = `scale(${v})`,
  onComplete: () => {
    animate({
      from: 0, to: 15, duration: 150,
      onUpdate: v => icon.style.transform = `rotate(${v}deg)`
    });
  }
});

9. Timing

9. 时间节奏

javascript
import { spring } from "popmotion";

// Fast
animate({ from: 0, to: 100, duration: 150 });

// Spring physics
spring({
  from: 0,
  to: 100,
  stiffness: 300,
  damping: 20,
  onUpdate: v => element.style.transform = `translateX(${v}px)`
});

// Slow
animate({ from: 0, to: 100, duration: 800, ease: easeOut });
javascript
import { spring } from "popmotion";

// Fast
animate({ from: 0, to: 100, duration: 150 });

// Spring physics
spring({
  from: 0,
  to: 100,
  stiffness: 300,
  damping: 20,
  onUpdate: v => element.style.transform = `translateX(${v}px)`
});

// Slow
animate({ from: 0, to: 100, duration: 800, ease: easeOut });

10. Exaggeration

10. 夸张表现

javascript
spring({
  from: { scale: 1, rotate: 0 },
  to: { scale: 1.5, rotate: 720 },
  stiffness: 200,
  damping: 10, // low = overshoot
  onUpdate: ({ scale, rotate }) => {
    element.style.transform = `scale(${scale}) rotate(${rotate}deg)`;
  }
});
javascript
spring({
  from: { scale: 1, rotate: 0 },
  to: { scale: 1.5, rotate: 720 },
  stiffness: 200,
  damping: 10, // low = overshoot
  onUpdate: ({ scale, rotate }) => {
    element.style.transform = `scale(${scale}) rotate(${rotate}deg)`;
  }
});

11. Solid Drawing

11. 扎实构图

javascript
animate({
  from: { rotateX: 0, rotateY: 0 },
  to: { rotateX: 45, rotateY: 30 },
  duration: 500,
  onUpdate: ({ rotateX, rotateY }) => {
    box.style.transform = `perspective(1000px) rotateX(${rotateX}deg) rotateY(${rotateY}deg)`;
  }
});
javascript
animate({
  from: { rotateX: 0, rotateY: 0 },
  to: { rotateX: 45, rotateY: 30 },
  duration: 500,
  onUpdate: ({ rotateX, rotateY }) => {
    box.style.transform = `perspective(1000px) rotateX(${rotateX}deg) rotateY(${rotateY}deg)`;
  }
});

12. Appeal

12. 吸引力

  from: 1,
  to: 1.02,
  duration: 300,
  ease: easeOut,
  onUpdate: v => {

    card.style.boxShadow = `0 ${20*v}px 40px rgba(0,0,0,${0.2*v})`;
  }
});
