Removing Group Vs Removing Children

Getting Started Newbie Questions
#1

Hi I’m new to programming and just wondering what the difference is between using object:removeSelf() on the group vs iterating through the group and removing the children first before removing the group? Is there a big difference in the memory that you get back?

#2

I know there is more good answer than this but based on my understanding *If your object:removeSelf() means group:removeSelf()* If you remove the group directly without iterating then there is no way for you to remove its child’s memory usage. *Were the childs memory usage will still be there and also with texture usage*

Iterating first is much better before removing the group

Hope this helps =)

There is no difference. If you remove the group, all its children will be removed.

display.remove( myGroup )
myGroup = nil

–OR

myGroup:removeSelf()
