Practice loading animation, found that such a simple effect also has a lot of small points of knowledge, summed up to share with you, I hope to be helpful to those in need.
We start from scratch and grow with everyone in our studies.
Let’s look at the effect first.

 

The first step is to build synthetic 800*800 (the size of your own decision is good), the background is #000000.

The second step is to draw the triangle.
There are many ways to draw a triangle.
Create a shape layer on the composite panel, click add, select polygon star, and set the “dot” to 3.

Adjust the triangle to the appropriate size and position, continue to click Add Fill to set the color of the triangle; Add Scrub to set the triangle to rounded corner (Scrub Segment Connection to Rounded Corner Connection), set the width of the edge as needed, and keep the color of the edge consistent with the fill color, below It’s my parameter.

After drawing, copy one layer (Ctrl+D) and adjust the color.

Third step mobile location
First, adjust the initial position of the two triangles. The two triangles are diagonally aligned and slightly overlap (depending on personal preferences), as shown in the figure

Select the two triangles (remember to name the layer to distinguish them) click the “p” position option and type a key frame at the starting point; adjust the position of the triangle in turn, the key frame stays at 1S, and move the white triangle to the left above the Yellow triangle, and the yellow triangle to the right below the white, as shown in the figure

Continue to adjust the position, type a key frame at 2S, and move the white triangle down the diagonal, the yellow triangle up the diagonal, as shown in the figure

Continue to move the position, type the key frame at 3S, copy the key frame at 0S directly, and let the moving path form a closed triangle.
Note: The path of movement is a curved triangle, where you select the pen tool, click the anchor, and the curve becomes a straight line (equivalent to the conversion point tool in PS), as shown in Figure

Select the position keyframes of the two triangles and set the slow motion, shortcut keys F9 (or click animation-key frame assist-slow motion) for each frame to optimize the animation effect.

The fourth step is to add the empty layer.
Create an empty layer, add the rotate animation, and shortcut key R. Put the key frame in the initial position, rotate 0; move the key frame index to 3S (that is, the end point), set the number of rotation cycles to – 1, that is, counter-clockwise rotation 360 degrees (related to the direction of the triangle just set).
Hide the empty layer, select the parent of the two triangles as the empty layer you just created, add a rotating effect to the animation, and make the animation join more smoothly, as shown in Figure

Well, the boring process has finally passed. Let’s look at the results.
