In short :slight_smile:

How to dispose properly this object

local imageSheet = graphics.newImageSheet()

it has no functions or variables assigned to it, just .userdata

imageSheet:dispose()
nor
imageSheet:removeSelf()
nor
imageSheet = nil

does not free the memory, even when no sprites from this sheet were created.

Hi,
the blog post says:

boomBloesemAnim7:removeSelf( )
boomBloesemAnim7=nil
boomBloesemImageSheet=nil

Might be the garbage collecting that is garbage.

local boomBloesemImageSheet = graphics.newImageSheet("…")
boomBloesemImageSheet = nil

does not free memory or do i miss something ?

imageSheet object does not have any functions nor parameters to change. It can just be nulled.

Any ideas where is problem ?

ive been trying to test it and have no positive results.
It seems that GC is NOT collecting imageSheet object.

Might be that GC thinks it is not needed yet and that it will dispose after a while if other things take up more memory.
I always thought reference counting was a pain in Obj C, now I actually prefer it to this thing Lua/corona does. [import]uid: 100901 topic_id: 25570 reply_id: 103838[/import]

Solution to this one is to run GC with slight delay like 1-10 ms then it properly clean memory from sprite objects. [import]uid: 111283 topic_id: 25570 reply_id: 106312[/import]
