I remembered an old rapid prototyping challenge for a game revolving around shadows. I would like to have a character that has to move from point A to point B in a level, while staying in the shadows cast by level design blocks and one or more moving lights. He takes damage while out of the shadows.

Is there any way of detecting that a sprite is intersecting with the shadow cast by another sprite?

The only way I can think of is to check the colors at future sprite position with some detectors.

Anyone has a better idea? Thanks.

Hello, I'm a game designer by trade and I was looking for a rapid prototyping tool and found Construct, which is awesome by the way. I worked with Multimedia Fusion for a while, so the concepts are familiar to me, but Construct is already better than MF, and I love it in spite of its small flaws >_<
