Mmm, no it won't. These lines:
sprite(4).locH = 1.0* a * (t 0.05) halfStageHeight/2
sprite(4).locV = 2.0 * a * (t * t 0.05)
don't work. There are math operators missing.
Also doing all that in a repeat looop will halt everything else while
the loop executes. If you put those values into properties and
refresh when the playback head cycles through -- that is, write them
out to be used as framescripts -- you'll keep Director, the computer
and the user happy.
You will then also have the control you need to keep another sprite
"attached" to this one.
