Hi,

I am experimenting pointOnpath. I animated some stuffs using this expression. but somthing happens when it is applied on 'triangle' shape. I activate 'orient along path'. but smhow it stops working at trim path 'end' point and flips back.

both in 'round' head and 'traingle' head the anchor points are set in the 'middle'.

I need guidance. 😥 😭

Usually, all you have to do is click on the last position keyframe, open Keyframe Interpolation (Alt/Option + Ctrl/Cmnd + K), and change the Bezier Interpolation. It takes about 2 seconds.

It's a small bug, you can fix it by removing the Auto Orient Along Path option and using this expression on the

rotation property:

endTime = effect("Slider Control")("Slider").key(2).time;
if(time < endTime){
  v = position.velocity;
  value + radiansToDegrees(Math.atan2(v[1], v[0]))
} else{
// Add your correct value here
}

The idea is to retrieve the rotation value just before the bug and use it for the rest of the animation.
