Hi all -- I've taken interest in using Livecode for displaying ticker tape
or digital signage type information. There were a few older forum posts on
this topic a few years ago but haven't seen any recent activity in that
area. Does anyone have a general direction or sample stacks I can start off
with? I have purchased Animation Engine and thought that may be the way to
go but I am only at the beginning of this project so any input would be
welcome. Thanks!
There are two basic ways to do this:
1. Put the text into a field and move the field. The "move" command
should do this efficiently, or you can use animation engine. When the
right edge of the field goes off the left edge of the stack, reposition
it with its left edge at the right side of the stack and move it again.
This produces a smooth glide.
2. Put the text into a field with enough leading spaces to visually push
the actual text off the right edge of the field. Adjust the text
repeatedly by removing the leading character and placing it at the end
of the field text. This method produces an effect more like a stock
ticker, where the text jumps from one position to the next (the way LED
lights would work.)
Both are pretty easy to script. In either case, you'll need a field with
at least locktext and dontwrap set to true.
