Extreme Noob question regarding capabilities

Thu Sep 01, 2011 6:51 pm

All,

First, I am really new here with development for the Roku, but I have some programming experience, so I'm looking at tackling a channel. Is it possible to create a slideshow with individual slides that contain text and images (and maybe video) and just have them cycle endlessly with some kind of timing? I'm thinking of those TVs in the lobbies of buildings that cycle through event slides or videos of what a company develops or new things it is announcing... Is that possible?

oh, and how hard (relatively) is that to do?

Thanks!!

Tony

roSlideshow can do that minus the video. What's easy for us might not be easy for you. You basically populate your slideshow graphics, your overlay text, and set the interval and it does everything else.

That sounds great.

But could I write a script that incorporates the slideshow and once it completes, show some videos, and then start over? I'm thinking of an overall presentation thing where it might be:

1) slideshow
2) short videos
3) more slides (different than #1)
4) some animation
5) more short videos
6) GOTO #1


Thanks again. I appreciate it!

You might, if you're tracking how much time has passed for the slideshow.

I would, try to figure out how to do it with roImageCanvas, instead. A bit trickier, just because imagecanvas is kinda weird, but ultimately you can do it pretty much exactly the way you want it.

Also, don't use goto unless you have no choice, instead, use a while loop

while true

...do stuff
if stuff=done then exit while

end while
