I created 10 objects this morning. I set the Object Interval down at a
ridiculous 1 minute. By the time I had the 10 objects created, they were
being sent out about one every 10 seconds. I then added an 11th object,
this one moving. Still, the objects were just sent out once a minute but
with 10 seconds between each one. I later played around with longer
times. With the object interval set to 10 minutes, they were again sent
out every 10 minutes, but with a 10 second gap between each one. I
didn't create 30 objects, but I had no reason to believe that the
program would act differently whether there one or ten or thirty
objects. No, they aren't sent at a decaying rate, but I just couldn't
get it to send 30 seconds of objects the way you were describing. I
couldn't even get it to send two objects with no gap in between.
This was on UI-View32 ver 2.03. What version of UI-View were you using?
I just couldn't replicate what you were describing. The object interval
is set in SETUP - MISCELANEOUS.
Is there anyone using an old version of UI-View32 or the really old 16
bit version that could try this?
