Hi Alastair, in my experience the Timeline patch is great for such things! I looked at your composition and have an optimization suggestion: (I am sure you know all about this, its just for the records ;-) )
You don't need to have two calculation paths for you "time value" and two separate Timeline patches. I would suggest to combine the two Timeline patches in one, because then you see both of the animation paths in one graph (click on "Add New Timeline" at the bottom of the Timeline patch graph)! This is very helpful to synch them. In my opinion it is a good idea to have the timeline timebase only running between 0 and 1. (You can zoom in on the time axis and the value axis separately in order to have the same precision for editing) With this you always know what you have to put in the "Patch Time" of the timeline patch and you don't struggle with your Interpolation patch and the "Duration" input. Something similar applies to the output value of the Timeline patch: I often let them run between -1 and 1 (or 0 and 1) and use them as a base in a Math patch. In your composition you would be able to dynamically adjust the range of the X-Position of the Billboard patch displaying the text which may be important because your text can go wider than the screen width (in this case the text won't move out of the screen completely, right?) The Math-patch could have a formula like this: BillboardXPosition = TimelineValue * ((RenderingDestinatinDimensionsWidth + ImageWithStringDisplayWidth) / 2.0) I hope this make sense. best, Achim Breidenbach Boinx Software Ltd.
