    Posted by Chi-ho Lee on April 14, 2005 at 5:19 pm

    Hey All,

    Wonder if anyone has an answer for this….I’m using Edge Collision to make things bounce around the screen. But they are bouncing outside action safe. Is there a way to contract the bounce edge so they are closer to the Action safe lines…..know what I mean?

    I’ve tried cropping the layer, but that didn’t work, it’s still using the original 720×480 as the bounce edge.

    Many Thanks,

    CHL

    Me neither. Orlando Luna and Damian Allen both said to export it as a movie and re-import and scale down or create a new project based on action safe frame size and re-import into regular sized project file. It may be a good update request since if we are watching it on a TV, we can’t see the object bounce against the TV screen since it is outside of action safe.

    You could try convert to keyframes, then drag the resulting position keyframes in the canvas towards action safe.

    Can you set the bouncing objects in a bigger background and then bounce that? For example, let’s say you want to bounce a still around the screen. Open this sill in Photoshop, expand the canvas size by 30 percent for this element. Now your elements edges are further away and will bounce within action safe. Make sense?

    Ah, yes, I see. Interesting idea. I did crop the edges of the stills to make them smaller so they will bounce closer to the edges. Here’s the rub….it’s for a DVD menu – once I make it for action safe, when someone watches it on a computer, then the bounce is no longer decent since there is no action safe….what’s an editor to do?

    Yeah, that’s what I thought when I first read this, plus the fact that different TVs have different screen areas, right? So it’s never going to be perfect.

    Maybe create arwork that looks like a frame of some sort and have it inside that?

    Anyway, I think Creative Mac (David Nagel) had a tutorial on creating a pong game with a ball bouncing off of paddles. This used edge collision that wasn’t the screen, but was objects. Maybe you can look that up and it will help?

    Here it is:

    I think the credit should go to Jayson Steckler really 🙂
