How do I... make a layer "solid"?

I have two layers. Each layer has at least one clickable sprite. Some of the sprites overlaps ( but on different layers ). The problem is that clicking on the top layer sprite, will trigger the click event also on the bottom layer sprite. I tried making the bottom layer invisible. Is the same. Even if I have no sprites on the top layer and this is set to "Transparent: No", it'll still trigger the click events in the bottom layer. In conclusion: can I make a layer to NOT allow clicks through?

You can add a condition "Is on layer X" to your event. Would that solve your problem?

Like a charm! Thank you!
