The animation guide in Adobe Animate (formerly Flash Professional CC) helps you enhance the animation you create by defining a path for the objects you animate. This is helpful when you are working on an animation that follows a path that is not a straight line. This process requires two layers to carry out an animation:
Animation guide works only on Classic Tweens.
For more information on Animation Guides, see Working with classic tween animation
You can animate an object based on the variable thickness of the stroke of the guide path.
Apart from the keyframes for the initial and final positions of the object, you do not need any other keyframes to denote the variation in stroke thickness.
For more information on variable width stroke, see Variable Width Strokes.
Once you have a variable width stroke defined as a path, if you run the motion tween, you can see that the object not only follows the path, but also changes its size based on the relation to the variation in the thickness of the stroke.
Here is an example that uses Animation Guide with variable width stroke:
A motion guide path can have multiple segment with each connected segment having a different variable width profile specified as shown below. With no additional keyframes for the object, each segment's width profile is considered during the animation.
Animation Guide also enables you to tween an object along the path, by changing the color of the object based on the color of the guide path itself. To bring about this variation, you need at least two segments in the path, that is, three minimum nodes or points as part of the path. To achieve this, while creating a Classic Motion Tween and drawing a guide path as described in the previous section of this document, use the pen tool and draw a guide path as shown below. This path has four nodes/points in three segments.
Apart from the keyframes for the initial and final positions of the object, there is no need to create any more keyframes to denote the variation in stroke color.
Run the animation now to see the color influence of the guide path on the object itself in the course of the tween. You can see that the influence is not just on the color, but also on the alpha/opacity value of the stroke segment in the guide path.
Here is an example that uses Animation Guide with color variation:
