How does an appear to move along a path

Steps: 1. Create a layer, assuming that the layer is "Layer 1", in Layer 1, draw the figure (such as a circle) to be moved along the path, and then convert it to a component. 2. 2. Right-click on Layer 1, select "Add Traditional Motion Guiding Layer", and draw the motion path in the guiding layer. 3. Extend the frame number of the guiding layer, e.g. to 30 frames. 4. Similarly, extend Layer 1 to 30 frames, and create a keyframe at 30 frames of Layer 1; right-click on the first frame and select "Create Traditional Interval". 5. Select the circle in Layer 1, and on the first keyframe, place it at the start of the path line, with the center aligned with the start of the path (it will be snapped on automatically); on the second keyframe (frame 30), place it at the end of the path. 6. Test playing the animation.
