How do I sine with more precision?

I'm trying to make this circle move the point X to the point X + A, using sine behavior, but the construct does not have the option, the construct of the sine always seems to move from the center of the object to the sides, and I like the left to right or right to left, as in the photo, any ideas?

Set the offset to either 1/4 or 3/4 of the duration of the sine.

did not work :(

I would use the tween behavior. Tween one value (x + A). You could even give it a tag and do:

On tween end “IN”, start tween “OUT” (x - A).

And then vice versus if you wanted it to still sine indefinitely. That will be the most accurate.

I think easings.net will be the best place to look at the curves you can choose from.

I tried with timer and tween, but it did not go well, maybe I did not set it correctly
