I’ve had to make a tiny tweak to startPos to make it fit around my own terrible scripting, but that’s done the trick. Thanks so much!

startPos = L.toComp(L.anchorPoint) – [w,0]; is giving me an “Invalid or unexpected token” error.

Currently investigating.

Haha! Hi, Trent. I’m glad you like it. Most of the stuff I’ve done in expressions has been for dynamic setups like text that can be of any length etc.
The following on the circle’s position almost works:-

rectLeft = thisComp.layer(“rectangle”).sourceRectAtTime().left;

rectRight = thisComp.layer(“rectangle”).sourceRectAtTime().left +…

Tagged as “Basic”, but might not be.

I have a rectangle, the width of which is controlled by the SourceRectAtTime() of a text layer.

I also have a circle. At 0 frames, the circle needs to be at the left edge of the rectangle. at 25 frames, it needs to be at the right edge.

Regular keyframes obviously aren’t going to cut it because the rectangle can…

A further question for Filip: your example appears to be for one slider. How do I adapt switch(sl) to account for a second slider?

Thanks.

EDIT: Never mind. I’m redirecting the two sliders to an intermediate third invisible slider that I’ll point switch(sl) at.

Oooh, this is exciting. I’ve not come across switch statements before. Thank you. I will adapt this to my comp.

To answer your question: depending on the combination of slider values chosen by the user, there are 68 possible outcomes and I need to cater to all of them. I didn’t ask for this stupid thing, I just have to make it!

Apologies. This is my first time in the redesigned forum and couldn’t find it.

Who’s in the mood for another expression discussion?
I have layer that needs to move on the Y axis (dimensions already separated). It always starts in the same position, but the ending position needs to be linked to the values of two Math.rounded sliders that control other parts of the comp..

So it always starts at Position A and I need to… Read more
