I've written an XCMD for HyperCard that does diagonal screen wipes. Although
I am not quite happy with it yet, I'd like to ask at this point if the following
is kosher under HyperCard:
Drawing into the current Grafport.
I do save the penState. Is this ok? I've only tried it on a II, and it works
fine, even under color.
Will this code break? Since there currently is no way to add in your own
visual effects, and the only way I have figured to get a bitmap of the
destination card ('go to next card' type thing) is to use the clipboard, and
lockScreen. Any suggestions?
Also, while I am at it, are there any requests for styles of visual effects
that I might try? I am planning to offer all four diagonal wipe directions,
and can easily add more.
My interface is as follows:
myWiper 1, "ffffffffffffffff"
The first arg is the number of ticks to use as a delay during the wipe,
effectively offering different speeds. The second arg is the pattern to
use for the wipe. A third arg will probably be inserted between these,
offering a numeric selector for wipe style (i.e. directions aren't yet
implemented...)
Is there a nicer way? Can I do the following:
myWiper slowly, "ffffffffffffffff"
Will that be better? Offering say, 0 through 5 for tick delays?
Any ideas/comments are appreciated.
