Hi,
i’am currently trying to create a starfield within Corona. But i cannot see any ability to :
Am i seeing anything wrong here ?
I cannot find a like: beforeEnterFrame or so
So my question: Can we make use of a backbuffer to draw everything before showing to screen and how ?
Cheers,

Another thing:
How to remove / release an object or child within a group ? [import]uid: 2734 topic_id: 282 reply_id: 365[/import]
Conceptually, there is no back-buffer: You register “enterframe” event handlers, within those handlers you update your display objects, after, and *ONLY* after, Corona has called all registered “enterframe” handlers, Corona then draws all active display objects to the screen.
Now, since Corona uses OpenGL ES, behind the scenes there is, of course, a front/back-buffer scheme being used to avoid flickering/tearing of the screen image, but those using the SDK don’t need to be concerned about that.
As to your second question, you’d use the “group:remove(IndexOrChild)” method to remove an object from a group, and then make sure there are no references to the removed object so it gets garbage-collected properly.
BTW, more detail answers to both your questions can be found in the docs …
