How can I prevent an object to be dragged out of a frame? I don't want to use the option "return to original position if not dropped" because I want the object to be positioned anywhere into the frame.
So far the draggable object can go outside the frame and with a black background the object disappear. How can I prevent that?
Thanks

Opus XE 5

Hi Isma,

I think this needs to be done via script as it's not an option in Opus. I don't have access to Opus 5 on this machine so cannot post an example but something like:

1. Add trigger - mouse click - to object

2. Add script that gets object's position. Checks this position against boundaries of frame. Returns object if outside boundaries.

Thanks again Mack. If you have the oportunity to send me an example I would really apreciate it, becuase I cannot program scripts but I can change parametres of easy ones as I did sometime ago with one you sent me. Opus xe can open examples made with 7.

Isma,

That's an interesting problem. Perhaps you can manage it with some standard triggers and actions.

What I would try: Create 4 narrow or long rectangles, and place them over the sides of the Frame.

For a Trigger, the most simple approach is to use 'Collision Entered' for the object being dragged... and check all 4 of the boundary rectangles. For an Action, you can either Disable the dragged object to stop it in place, or you can Move it where you want. A bit more sophisticated solution would be to have 4 triggers and detect collision enter separately for each of the 4 boundary rectangles. Then you can Move the dragged object in X or Y specifically for that boundary.

Hope that helps.

Thanks Godlike,

I have tried both possibilities, and 2nd one works ok, not perfectly but works.

I thought the methods works when I first tried them. I just reran them in Preview and find it either does not work, or does not work well. I think the speed of User dragging is a factor. I cannot think of others ways currently. You may need to try Mackavi's suggestion and use scripting.
