X and Y position modifier
hello, i am trying to link the x and y position of a null object to the x and y position of the effect ¨CC Cylinder¨
Now the problem is that the value position of X in the null object is 614 and 614 for the cylinder would be 80.
Which means the middle of the comp for the cylinder is [0] but for the null object the middle would be 640.
The values are different, is there any way to make them equal? idk if i can explain myself, i basicly i want the cc cylinder effect to follow the null object x and y positon.
Thanks!

I think it’s going to look like this for x:
fromComp(thisComp.layer(“Null 1”).transform.position)[0]-width/2
and this for y:
fromComp(thisComp.layer(“Null 1”).transform.position)[1]-height/2

Could you explain the expression used here? id like to know what it is exactly doing in case i´d like to modify it!
Thanks a lot.

fromComp() converts the null’s coordinates from comp space to the layer’s space, [0] gives you the x component, -width/2 corrects for the fact that [0,0] in layer space is the upper left corner but it’s the center of the layer for CC Cylinder.
