Detailed method of using AE loopout expression to create a rotating windmill animation

php editor Apple today will introduce to you a commonly used expression production technique - loopout. By using loopout expressions, we can easily create interesting windmill animation effects to make your animation more vivid and interesting. The loopout expression is a very practical expression that allows the animation to play in an infinite loop without manually adjusting the animation duration. Next, we will introduce the use of loopout in detail, so that you can master this technique and add more creativity and fun to your animation.

1. Create a new composition (CTRL N) and use the pen tool to draw a semicircle (if there are other ways to draw a semicircle, it will work).

2. Duplicate the semicircle layer with ctrr D and adjust the anchor points so that the anchor points of the four leaves are in the same place. This is to prepare for later rotation.

3. Make a pre-synthesis of the four layers to facilitate unified control. The pre-synthesis shortcut key ctrl shift c

4. Please note here that the pre-synthesis Use the anchor point tool to drag the synthesized anchor point to the center of the windmill, otherwise the windmill will not be able to rotate around the center point.

5. Open the rotation attribute of the pre-synthesis, k two key frames, 0 degrees at 0s, 360 degrees at 1s or 0 degrees directly (it will rotate once anyway), play it at this time As a result, the windmill rotates within 0-1s, but stops after 1s.

#6. At this time, the loop expression comes in handy. Press the [ALT] key in the pre-synthesized code table and add the AE loop expression loopOut(type = "cycle" , numKeyframes = 0), so that the windmill will rotate in an unlimited cycle, and a small windmill animation is completed.
