I have some sprites that literally only have two frames and I need to switch between them based on user activity. But as best I can tell from Beebe’s tutorial, the frame data is read only?
Is there a way to simply set the frame? (Or maybe a way to play an animation in reverse?) Neither seems possible but it’s entirely possible I’m missing something.

Hey Richard,
Are you using the new sprite API or the “old” sprite API? [import]uid: 52491 topic_id: 26462 reply_id: 107390[/import]
The new stuff. Always the new stuff for me!
I’m guessing maybe the only way is to make a custom animation frame table with reverse order, and then detect which frame it is? Seems like an awful lot of work just to flip frames…
EDIT: Oh, I guess you can’t do that.
When I specify a frame order that does not go forward, even partially, I receive a warning that Corona is attempting to reference frame index 0 and the frame sequence sort of randomly sputters. [import]uid: 41884 topic_id: 26462 reply_id: 107406[/import]
Yep, it’s possible. I recently covered this with another user; scroll down to comment #15 and onward in the following discussion:

The key is, you still need to make the object into a sprite. You can’t just swap frames from an image sheet directly. Once it’s a sprite, you can set the frame with one command.
Hope this helps,

Perfect! Thanks Brent! I was hoping for a frame setting command but lost hope since the API Docs and the Tutorial both do not discuss it.
The frame order thing…I guess I should submit that as a bug? OOO frames seems like a really obvious thing to have given how we need to manually set frame order in the sequence table… [import]uid: 41884 topic_id: 26462 reply_id: 107513[/import]
