Dynamic Text in FPP
Hi,
I've been trying to incorporate a small swf hotspot into my tours, one which simply loads text from a given file and presents it against a background. The concept is for presenting information about the room being viewed. This would mean that the controlling xml would not need to be maintained should the text need altering. It is also better suited to templates.
I've tried several methods, but each time the swf loads fine, presenting the chosen background, but the text does not get loaded into the hotspot. I retain the text file in the same directory as the swf and if I run it standalone it works fine.
The very simplest form uses one line of actionscript , basically:
loadVariables("sample.txt", this);
where the file sample.txt contains the variable values.
I'm quite new to Flash, so may be missing something very obvious.
Please can you advise
Thanks
Martin

This is actually quite easy
This is actually quite easy to do. I can get you some actual code to do this when I get to my other computer.

Great!
Thanks Zephyr, I look forward to seeing how it's done.
I've also tried loading 'flipping book' swf engines as hotspots. Again they work if the page data is internally defined, but once they reference external jpegs/swfs as page data it doesn't appear. Usable, if a bit limited. I'm hoping the solution to my dynamic text woes may help ....
Cheers!

Thanks!
Hey Zephyr, that's a very detailed reply, brilliant!
Many thanks for sharing your knowledge, it is most appreciated.
This will keep me quiet for a while.
Cheers!

Hi! Thx for the detailed
Hi!
Thx for the detailed reply but what is Boxbg in your source? It seems to be a missing custom class...
Could you please also post it here?
Text box hotspot
I also needed a hotspot just consisting of a text box where I could put some text, so I pieced together this little hotspot plugin. I wouldn't say it's perfected yet (there is some matter with the "justify" parameter), but it is definitely in working order, so you are welcome to try it.
You can download it here. The zip contains the .fla, .swf and a small text file listing the supported parameters, so if you have Flash (CS3) you can modify or add as much as you like.

Tommy
