Can somebody please post a comprehensive guide on Corona's culling?

Solar2D General Questions/Discussion
#1

I haven’t been able to find anything in the docs (or maybe I’m not looking hard enough), but the only information I see is other developers posting forums topics.

Basically, the things I want to know are:

  1. Which objects are affected by culling?
  2. How often does culling occur?
  3. Under which circumstances will an object be culled?
  4. How can I know if an object has been culled?
  5. Is there any way to turn it off?

I have a word game where you can place tiles down and zoom in on the board and pan around. Sometimes the player’s tile will be out of view for a while. Do I have to worry about their tiles disappearing?

I appreciate any input. Thanks!

You do not need to worry about your tiles getting culled or disappearing.  Unless you delete an object yourself, it will always be retained.

PS - If you’re using composer, storyboard, or another scene manager, then the manager will remove objects inserted into the supplied scene group, but that is a different topic and I would expect those who use these managers will understand how they are used and when they ‘automatically’ remove content.  

Just clarifying in case someone chimes in saying ‘composer…’ or ‘storyboard…’.
