display.save() saves everything and not just display group?

Games
#1

I thought display.save() would only save the group in the parameter, but it does not seem to be the case, or I’m doing something wrong.

I want to save only the screen display, without the navigation buttons. So I have
local localGroup = display.newGroup()
local pixGroup = display.newGroup()

Then I insert the navigation buttons directly into localGroup, but I insert the background and other images into pixGroup, then pixGroup into localGroup, to keep them separate.
pixGroup:insert(bg)
localGroup:insert(pixGroup)

When I do the save, I got everything including the navigation buttons
display.save( pixGroup, fileN, baseDir )

Am I doing something wrong?

Thanks

Are you inserting pixGroup into localgroup or vice versa? If you are then that is the problem [import]uid: 84637 topic_id: 26211 reply_id: 106572[/import]

Hi Danny,

Yes, I inserted pixGroup into localGroup for display, but my save statement is only for pixGroup
display.save( pixGroup, fileN, baseDir )

Why wouldn’t just save pixGroup? [import]uid: 108015 topic_id: 26211 reply_id: 106670[/import]

Hey Fly,

I am not sure if I misunderstood or not but testing this;
[lua]local myObject1 = display.newRect( 50, 50, 100, 150 )
local myObject2 = display.newCircle( 100, 300, 50 )
local myObject3 = display.newCircle( 210, 300, 50 )

local g = display.newGroup()
local t = display.newGroup()

g:insert(myObject1)
t:insert(myObject2)
t:insert(g)
t:insert(myObject3)

local baseDir = system.DocumentsDirectory
display.save( g, “entireGroup.jpg”, baseDir )[/lua]

Seems to work just fine for me.

Do you have a sample that shows the issues you having you could share? [import]uid: 52491 topic_id: 26211 reply_id: 106682[/import]

Hi Peach,

Thanks for looking into this. I wonder if my test version is a bit out-of-date, my ui.lua was not behaving the way things are described, and it was fixed when I downloaded the latest version. Will look a bit later.

Any how:
I insert the background and some line drawings into pixGroup, then insert pixGroup into localGroup;
I insert the navigation buttons directly into localGroup

 local localGroup = display.newGroup() -- whole display  
 local pixGroup = display.newGroup() -- bg and images   
...  
  
 local function bgimage() -- inserting a background image  
 local bgname = bgpix[1]  
 local bg = display.newImageRect(bgname, dimx, dimy)  
 bg.x = halfx bg.y = halfy  
 pixGroup:insert(bg)  
 localGroup:insert(pixGroup)  
 end  
  
 local function sizbutton() -- navigation and control buttons  
 localGroup.pb00 = ui.newButton{  
 defaultSrc = "b00.png", defaultX = 70, defaultY = 40,  
 overSrc = "b00.png", overX = 70, overY = 40,  
 text = textSize,  
 textColor = { 51, 51, 51, 255 },  
 size = 22,  
 }  
 localGroup:insert(localGroup.pb00)  
 localGroup.pb00.x = butx5 localGroup.pb00.y = buty59  
 ...  
 end  
  
 function newLine(event) -- draw some lines  
 ...  
 end  
  
 function savef() -- save the bg and lines  
 local baseDir = system.DocumentsDirectory  
 local date = os.date( "\*t" )  
 local fileN = fname .. date.year .. date.month .. date.day .. "\_" .. date.hour .. date.min .. date.sec .. ".png"  
 fnid[findex] = fileN  
 display.save( pixGroup, fnid[findex], baseDir )  
 findex = findex + 1  
 fprev = findex  
 end

It saves ok, but looking at the save file shows the navigations buttons as well.

Thanks

Hard to tell from the code you posted but just for the record, you should only need to insert pixgroup into localgroup once.

OK thanks, will work on my code a bit more. [import]uid: 108015 topic_id: 26211 reply_id: 106972[/import]
