  <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.10.3/gsap.min.js"></script>
</head>
<body>

  <svg width="100" height="100">
    <circle id="circle" cx="50" cy="50" r="40" fill="blue" />
  </svg>

  <script>
    gsap.to("#circle", {
      duration: 2,
      cx: 80,
      fill: "red"
    });
  </script>

</body>
</html>

Explanation:

  1. HTML Structure:
    • An SVG element is created with a width of 100 and a height of 100.
    • Inside the SVG, a circle with the ID "circle" is defined, initially centered at (50, 50) with a radius of 40 and a blue fill.
  2. GSAP Animation:
    • gsap.to("#circle", ...): Targets the circle element with the ID "circle" for animation.
    • duration: 2: Sets the animation duration to 2 seconds.
    • cx: 80: Animates the circle's center x coordinate to 80, shifting it to the right.
    • fill: "red": Animates the circle's fill color to red, creating a visual transformation.

Key Points:

  • The circle will smoothly move to the right and change its color from blue to red over 2 seconds.
  • This demonstrates how GSAP can animate both attributes and styles of SVG elements, allowing for dynamic and engaging visual effects within SVG graphics.

Example 2: Animating SVG Circles

Objective: Create a simple animation where multiple SVG circles expand and change color sequentially.

HTML:

<svg width="200" height="200">
  <circle cx="50" cy="50" r="20" fill="blue" class="circle"/>
  <circle cx="150" cy="50" r="20" fill="green" class="circle"/>
  <circle cx="50" cy="150" r="20" fill="red" class="circle"/>
  <circle cx="150" cy="150" r="20" fill="yellow" class="circle"/>
</svg>

JavaScript:

gsap.to(".circle", {
  duration: 1,
  r: 30,
  fill: "purple",
  stagger: 0.2
});

In this example, each circle expands and changes its color to purple in a staggered fashion, creating a simple yet effective animation sequence.

      duration: 1,
      r: 30,
      fill: "purple",
      stagger: 0.2
    });
  </script>

</body>
</html>

Explanation:

  1. HTML Structure:
    • An SVG element is created with a width of 200 and a height of 200.
    • Four circles are defined within the SVG, each with different positions and colors, and all assigned the class "circle" for targeting.
  2. GSAP Animation:
    • gsap.to(".circle", ...): Targets all elements with the class "circle" for animation.
    • duration: 1: Sets the base animation duration to 1 second.
    • r: 30: Animates the radius of each circle to 30, making them larger.
    • fill: "purple": Animates the fill color of each circle to purple.
    • stagger: 0.2: Staggers the start of each animation by 0.2 seconds, creating a sequential effect.

Key Points:

  • The circles will grow in size and change color to purple one after the other, with a slight delay between each.
  • The stagger property introduces a visual rhythm and draws attention to each circle individually.
  • This demonstrates how GSAP can animate multiple elements with staggering for dynamic and engaging visual sequences.

    • Two path elements are defined within the SVG:
      • path1: Initially visible with a blue stroke, representing the starting shape.
      • path2: Hidden with a red stroke, representing the target shape for morphing.
  2. MorphSVGPlugin Loading:
    • gsap.registerPlugin(MorphSVGPlugin);: Loads the MorphSVGPlugin, enabling SVG path morphing capabilities.
  3. GSAP Animation:
    • gsap.to("#path1", ...): Targets the "path1" element for animation.
    • duration: 3: Sets the animation duration to 3 seconds.
    • morphSVG: "#path2": Animates the "path1" element to morph into the shape of "path2", smoothly transforming its path data.

Key Points:

  • The blue path will seamlessly transform into the shape of the red path over 3 seconds, visually blending the two shapes.
  • The MorphSVGPlugin handles the complex path data calculations for a smooth and organic morphing effect.
  • This demonstrates how GSAP, with the MorphSVGPlugin, can create visually captivating morphing animations for SVG paths.

Example 2: Complex Path Animation

Objective: Animate an SVG path to simulate drawing and morphing into a different shape.

HTML:

<svg viewBox="0 0 100 100">
  <path id="startPath" d="M10,50 Q50,-10 90,50 T170,110" stroke="black" fill="transparent"/>
  <path id="endPath" d="M10,90 Q50,10 90,90 T170,90" stroke="black" fill="transparent" visibility="hidden"/>
</svg>

JavaScript:

gsap.registerPlugin(MorphSVGPlugin);

const tl = gsap.timeline();

tl.to("#startPath", {
  duration: 2,
  stroke: "blue",
  strokeWidth: 2,
  morphSVG: "#endPath"
})
.to("#startPath", {
  duration: 1,
  strokeDasharray: 400,
  strokeDashoffset: -400
});

This advanced animation first morphs startPath into the shape of endPath while changing the stroke color and width. Then, it creates a "drawing" effect by animating the strokeDasharray and strokeDashoffset.

      duration: 3,
      morphSVG: "#path2"
    });
  </script>

</body>
</html>

Explanation:

  1. HTML Structure:
    • An SVG element is created with a width of 200 and a height of 200.
    • Two path elements are defined within the SVG:
      • path1: Initially visible with a blue stroke, representing the starting shape.
      • path2: Hidden with a red stroke, representing the target shape for morphing.
  2. MorphSVGPlugin Loading:
    • gsap.registerPlugin(MorphSVGPlugin);: Loads the MorphSVGPlugin, enabling SVG path morphing capabilities.
  3. GSAP Animation:
    • gsap.to("#path1", ...): Targets the "path1" element for animation.
    • duration: 3: Sets the animation duration to 3 seconds.
    • morphSVG: "#path2": Animates the "path1" element to morph into the shape of "path2", smoothly transforming its path data.

Key Points:

  • The blue path will seamlessly transform into the shape of the red path over 3 seconds, visually blending the two shapes.
  • The MorphSVGPlugin handles the complex path data calculations for a smooth and organic morphing effect.
  • This demonstrates how GSAP, with the MorphSVGPlugin, can create visually captivating morphing animations for SVG paths.

Example 2: Complex Path Animation

Objective: Animate an SVG path to simulate drawing and morphing into a different shape.

HTML:

<svg viewBox="0 0 100 100">
  <path id="startPath" d="M10,50 Q50,-10 90,50 T170,110" stroke="black" fill="transparent"/>
  <path id="endPath" d="M10,90 Q50,10 90,90 T170,90" stroke="black" fill="transparent" visibility="hidden"/>
</svg>

JavaScript:

gsap.registerPlugin(MorphSVGPlugin);

const tl = gsap.timeline();

tl.to("#startPath", {
  duration: 2,
  stroke: "blue",
  strokeWidth: 2,
  morphSVG: "#endPath"
})
.to("#startPath", {
  duration: 1,
  strokeDasharray: 400,
  strokeDashoffset: -400
});

This advanced animation first morphs startPath into the shape of endPath while changing the stroke color and width. Then, it creates a "drawing" effect by animating the strokeDasharray and strokeDashoffset.
