Scripted animation triggered by the comp marker
Hello guys,
I’m new into expressions, and I would like to write an expression that combines two expression into one.
I’m using this expression to animate the position easeOut(t, 0, 1, [x,y], [x1,y1]), but I want to trigger this animation to start by passing by comp marker with a comment Start and then invert my animation by a comp marker comment end.
Why I’m using this expression easeOut(t, 0, 1, [x,y], [x1,y1]) because I need to link the [x,y] to a null position so I will be able to control my starting position manually.
Thank you for your help

Start here: https://motionscript.com/design-guide/marker-sync.html. If you want to use interpolation functions many times, check this: https://forums.creativecow.net/thread/227/30494.
If you only want to make one linear on one property controlled by markers you can write this:t1 = marker.key(1).time; // If the marker is on other layer : comp("xxx").layer("xxx").marker....
t2 = marker.key(2).time;
startPoint = [x, y];
endPoint = [x1, y1];
linear(time, t1, t2, startPoint, endPoint ); -
Thank you for your help,
The expression works fine but i’m still trying to figure out how to use the interpolation many times. i checked the links you sent me but its quit advance to my expression experience.
What i’m trying to achieve is applying this interpolation expression to position property of a layer to move from position1 to position2 triggered by Marker1 till Marker2 and hold till marker3 to move from position2 to position3 until marker4.
