How to master the startup layer when making flash animation

The guide layer can move the component along the line you specify. The specific manufacturing method is as follows:

1. Make the motion animation of 1 layer components, such as a butterfly flying.

2. Point to the layer 1 and right-click "Add Traditional Motion Guidance Layer". The second layer (boot layer) is automatically generated.

3. Select the first frame of Layer 2, and then select the pencil tool to draw the guide curve. (It is recommended to set the stroke of the pencil tool to 2)

4. Select the first frame of the layer 1 and move it so that the point at the center of gravity of its component covers the starting point of the guide line (accurately).

5. Select the last frame of the tween animation of layer 1 so that the point at the center of gravity of its component covers the end point of the auxiliary line (accurately).

In this way, the butterfly that has been flying along the guide line has succeeded. I made a source file for your reference.
