Many patch can be set to be controlled by an external patch time by selecting the patch and control+clicking. So, if you want to offset one interpolate (or lfo, etc.) in time from another, one can set each patch to external timebase, and then introduce a math patch in between patch time and that patch, at say +1, to offset that part of the chain from the other.
One can control patch time with a stop watch as well. This allows you to set an animation sequence into motion after a user event (eg., mouse, keyboard, etc.), instead of upon the composition running.
One can attach conditionals to a patch time or stopwatch output, so that when a value is greater than or equal to, the conditional outputs a true. This principal can be used to enable renderer patches (sprites, billboards) at given times, or to toggle multiplexers to different states.
Most importantly, there is an actual timeline patch, which is heavily programmable. Timeline can also be set to external timebase. This allows one to setup complex sequences that are triggered by something turning true, and enabling a Stop Watch connected to patch time of a Timeline patch.
I'm sure there are even more ways of sequencing events that I'm not thinking about off the top of my head.
Here's a further line of thought....
That conditional/patchtime or stop watch method, when attached to a Sprite (or other renderer) is kind of like a bang. It will cause the entire chain to execute. So, if you have an animation sequence that renders to one sprite, and then you want to trigger to the next sequence 10 seconds later, or at an arbitrary time, you can be doing this be setting things up so that Sprite 1 turns on, then 10 seconds later a conditional statement turns true, which turns your next sequence on.
A demultiplexer may also be handy for you. You can base your logic in a way that changes index values on a demultiplexer, causing different rendering chains to execute depending on the current index value. This can be set to turn other chains off via Settings.
I know this is kind of a sprawling response, but there's more than one approach to solve your scenario, so I'm trying to give an overview of various principles that may help you.
Best regards,

Hi Everyone,
I want to render a sequence of text animations (i.e. Text1 flies in
then fades out, Text2 flies in and fades out, etc). I have a macro
that uses the Image With Text patch to define the text, some
interpolations and do the animation, and ultimately renders to a
billboard. The issue is, when I play the composition, they all play at
the same time. I was tinkering with the _javascript_ patch and Patch
Time, but I just don't see a way to make the animation start delayed
(as in start the first at 0, star the second at 10, or simply when the
first finishes). QC is great, but it seems like a very declarative
paradigm where what I'm needing here is more "timeline" based.
Thanks all.
