Pixel Per second Expression with manual stop at the end
Hi
I was using this expression to create a slideshow of images moving across the screenveloc = 150; //Move object 150 pixel on x axis per second
x = position[0] + (time – inPoint) *veloc;
y = position[1];
[x,y]However I would like to be able to come to a stop at the end, I tried linking the 150 to a slider but when i animate this to zero it sends the whole thing back to the beginning.
Reason for this is that I want consistent speed of images in different comps, however some comps have more or fewer images.
Thanks in advance

Use a slider control to drive a linear expression to transition between that value and another one of your choosing.
something like:
veloc = 150; //Move object 150 pixel on x axis per second
x = 0 + (time - inPoint) *veloc;
y = position[1];
v1=[x,y];
v2=[value[0],y];
linear(effect("Slider Control")("Slider"),1,0,v1,v2)You can then move it to where you want it to stop and just animate a slider going from 0 to 1 to make it stop there. Change the “0” value in line 2 to set where it starts.

I would probably precompose and manually keyframe Time Remapping, so I could get exactly the easing curve I wanted.
