I’m working on a tilemap-based game and I’m thinking it is a lot more efficient if I just create one catch-all touch listener instead of adding a listener for each map element.
From what I’ve seen from the API and the sample apps, you usually attach an event listener to an image or a button. What do I do if I want to catch a touch, say, between (0,0) and (100,100) ?

You can attach event listeners to Runtime for global listeners:
Runtime:addEventListener("touch", listener) Does anyone know if doing it that way is more efficient? I have listeners added separately to up to 40 tiles and that seems to work fine. [import]uid: 12108 topic_id: 4614 reply_id: 14573[/import]
Thanks for the tip.
In my case a catch-all listener makes sense - I’ll use it for empty tiles.

jhocking - I guess you’re right. Setting up individual listeners makes the code a lot clearer. And it isn’t probably any more inefficient than setting up a catch-all listener. Thanks for the tip, though. [import]uid: 7026 topic_id: 4614 reply_id: 14631[/import]
