Layer slider with responsive positioning
Parameters:
1.Layer can be aligned in x-axis with adjustable even space in-between 
1.For that to happen, the anchor points of the layers must be centered
2.This prevents inconsistent opacity for the layers on both sides
2.If a layer scale changes, the spacing should change accordingly
3.Create a control that just change the active "tile";
Tiling formula
(target.width/2−space)−(active.width/2)(target.width/2-space)-(active.width/2)(target.width/2−space)−(active.width/2)
One direction
Two Directions
//POSITION
​
// VARIABLES	
space = 0;
dir = 1; // 1 for tile right, -1 to tile left
axisX = 1; // 1 to turn on, 0 to turn off
axisY = 0; //1 to turn on, 0 to turn off
​
// SETUP
target = thisComp.layer(index + dir)

​
s = sourceRectAtTime();
activeWidth = s.width / 2 * transform.scale[0] / 100
activeHeight = s.height / 2 * transform.scale[0] / 100
​
​
// EXECUTION: Center position to left of target layer, offset the width, + spacing
tpos += [(activeWidth + tSrc + space) * axisX, (activeHeight + tSrcY + space) * axisY] * dir;
