Simple Position Expression
Hi, I’m sure this is pretty basic, but I searched for it and couldn’t find anything.
I want to move the position of a layer in either x or y by a defined amount of pixels per second OR
Have the layer move on the x or y by a defined amount of pixels over the length of the comp
Any help is much appreciated!
Thank you

Here’s an expression that will move in the x and/or y direction based on pixel speeds you specify in the first two lines (it’s set up for the positive x direction, but just edit the speeds for different results):
xSpeed = 100; // pixels per second
ySpeed = 0;
t = time – inPoint;
value + [xSpeed,ySpeed]*t;This version is similar, but the first two parameters specify total pixels over the duration of the comp.
x = 500; // total pixels over comp
y = 0;
xSpeed = x/thisComp.duration;
ySpeed = y/thisComp.duration;
t = time – inPoint;
value + [xSpeed,ySpeed]*t;Dan
