Active Picture with alpha- selecting just 1 object

[aidmm]

I've got a simple app (for my kids) where I can drag and drop pictures (JPG and PNG) into the frame. Each time an image is dropped into the frame, it creates a new Active Picture with that image. I'm using PNGs mostly, so there are transparent areas.

I can move the images around in my frame with my mouse. All works well, until they start overlapping.

My Problem:
It seems that when the mouse is clicked, it detects the entire square of the Image, not just the parts that are opaque.

My hope is to find a way to only move the image that is clicked by the mouse on the NON-FULLY-TRANSPARENT portions of the Active Picture Object.

A way to determine the top-most Active Picture Object could be a great way to handle this.

any ideas?

thanks.

I just figured out a way to move only one object at a time...

I simply added: "Only once action when event loops" with my "User Clicks on Active Picture" condition.

(gotta love that condition!)

It would still be great to move the pictures ONLY by clicking on the opaque areas of the image.

Active picture doesn't have this option. They work as rectangles for collisions and such. It's just like an active with "Use fine detection" disabled.

You could get around this using an overlay outside the frame to detect the colour of the pixel you clicked. But it's a bit more complex...
