Alright I got something like that to work. I’m animating the slider with hold keyframes but feel free to try something else. I’m joining a screencast of how it’s behaving and my ae file also.

// Time Offset from Slider
var offset = effect("Slider Control")("Slider")/10; //dividing it by 10 becasue it's sensitive
// Total duration of the loop (from first to last keyframe)
var firstKeyTime = key(1).time;
var lastKeyTime = key(numKeys).time;
var loopDuration = lastKeyTime - firstKeyTime;
// Current Time adjusted by the offset
var adjustedTime = time - offset;
// Calculate the looped time
var loopedTime = (adjustedTime - firstKeyTime) % loopDuration + firstKeyTime;
// Ensure loopedTime doesn't go below the first keyframe time
loopedTime = (loopedTime < firstKeyTime) ? firstKeyTime : loopedTime;
// value at the looped time
valueAtTime(loopedTime);

Hi Griffin! Is the property only one value or an array of 2 or more?

[Yoan Boisjoli]

What I do is hold ‘Alt’ while pickwhipping a property, which makes it universal by addressing the index. However, at the end of a project, when I need to make it available in any language, I use the script Expression Universalizer.

If you set up a paragraph text box in After Effects, you can use an expression on sourceText to pull in text from your CSV and it’ll split the lines automatically to fit within the box. Something like this:

txt = footage("yourCSVfile.csv").dataValue([0, 0]); // Change this to point to your CSV file and correct cell
txt;

Hi Matthew! Are you talking about a paragraph text box?

In after effects if you simply drag a square with the text tool you can make a paragraph text box.

Let me know if this is what you are referring to.

Cheers.

There’s also this tutorial where it’s well explained:

Dan is right—expressions don’t store previous values and will only access the pre-expression value when referencing their own property. To hold the position after 10 seconds, you can use valueAtTime(duration) to “freeze” the last calculated position:

var duration = 10;
if (time < duration) {
    var progress = time / duration;
    [
        linear(progress, 0, 1, value[0], value[0] + 100), 
        linear(progress, 0, 1, value[1], value[1] + 100)
    ];
} else {
    valueAtTime(duration);
}

Yeah! After Effects’ keyframe indices start at 1. This means the first keyframe is key(1), the second is key(2), and so on !

Hey Hiro! I finaly got to test the expression and it wasn’t working so here’s a working one with the right steps:

1. Make a null object and link you camera to it.
2. add a dropdown menu and two sliders
3. paste this expression in the position:

// Retrieve the selected direction and duration
var direction = effect("Direction")(1).value;
var duration = effect("Duration")(1).value;
var distance = effect("Distance")(1).value;
// Define movement parameters
var startPos = [0, 0]; // Starting position (relative to current position)
var endPos;
// Determine end position based on selected direction
switch (direction) {
    case 1: // Bottom to Top
        endPos = [0, -distance];
        break;
    case 2: // Top to Bottom
        endPos = [0, distance];
        break;
    case 3: // Left to Right
        endPos = [distance, 0];
        break;
    case 4: // Right to Left
        endPos = [-distance, 0];
        break;
    default:
        endPos = [0, 0];
}
// Determine current position using linear interpolation
if (time < duration) {
    // Moving from startPos to endPos
    ease(time, 0, duration, startPos, endPos);
} else {
    // After duration, stay at endPos
    endPos;
}

Here’s a screenshot of how it looks for me.
