I know it is years later, but I am dealing with this same issue right now. No idea why they couldn’t just use text and change the data type afterwards. 😞

I didn’t see numProperties documented anywhere. Searched around before asking but I left my Javascript Manual at home since people were jamming it into AC vents to stop rooms from getting cold. I’ll double check it there when I get home but the code is working perfectly.

I am trying to figure out if there is an expression to count the number of effects on a layer.

Similar to the way numKeys or numLayers can return the number of keyframes or layers;

is there a way to get a number of effects on a specific layer?

toFixed was what I was thinking too. Don’t need to round.

commas and decimal points in source text expression

Works perfectly. I was thinking I would have to do so much more.

I don’t understand. I get how fromcomp works but not sure where to use. The point control on the layer is being pushed further from the anchor point (which is still 640,360 in center of layer) based on the scaling.

I am trying to write an expression on position to push the point control to 640,450 on comp.

I am trying to position a point control on a 1280×720 layer and have that layers point control moved to 640, 450.

The thing I think is messing me up is that the layers are all scaled differently.
