Collect all layers’ property value

[Dan Ebberts]

I’m not sure what you’re trying to do, but this would give you the layer directly below the layer with the expression:

thisComp.layer(index+1).timeRemap.speed

Thanks Dan, I’m actually looking to add together the values of ALL the layers below it.

So index+1,100 or something (assuming that would add all in that range), but it will probably require a qualifier for layers that have time remapping applied.

This might work:


tot = 0;
for (i = index+1; i <= thisComp.numLayers; i++){
try{
tot += thisComp.layer(i).timeRemap.speed;
}catch(e){
}
}
tot

Ah fantastic – that did work a treat, thanks Dan.

It did run me into another problem however.

I am trying to animate the rotation of an object based on the time remap properties of the other layers, so as they speed up, the rotation also speeds up etc.

However, when using the speed value , it works when the value is increasing, but as the velocity value decreases the object returns to it’s original position.

So I guess I need an accumulating only value – perhaps using a valueAtTime property, but I’m afraid it’s beyond me!

Any suggestion much appreciated!
