Creating a Group and how to unload?

Millerszone

I'm not very experienced with Lua, so I have a question about Creating a Group and
how to unload with Gideros. I know how to create a Group and upload with Corona.

Corona example:

-- Main menu screen   -- Create menu group local menuGroup = display.newGroup()   -- Display menu screen local menuBG = display.newImageRect("menu.png", 480, 320) menuGroup:insert(menuBG)   -- New game button newGameBTN = display.newImageRect("newgameBtn.png", 270, 36) menuGroup:insert(newGameBTN)   -- Settings button settingsBTN = display.newImageRect("settingsBtn.png", 270, 36) menuGroup:insert(settingsBTN)   -- Statistics button statisticsBTN = display.newImageRect("statsBtn.png", 270, 36) menuGroup:insert(statisticsBTN)   -- When I'm ready to unload the main menu I use this: display.remove(menuGroup); menuGroup = nil

Also is there a way to monitor Memory with Gideros like the cose below?

-- local monitorMem = function()   -- collectgarbage() -- print( "\nMemUsage: " .. collectgarbage("count") )   -- local textMem = system.getInfo( "textureMemoryUsed" ) / 1000000 -- print( "TexMem: " .. textMem ) -- end   -- Runtime:addEventListener( "enterFrame", monitorMem )

Hi,

You can use Sprites to group your display objects like:

-- Main menu screen   -- Create menu group local menuGroup = Sprite.new() stage:addChild(menuGroup) -- and add this sprite to stage   -- Display menu screen local menuBG = Bitmap.new(Texture.new("menu.png")) menuGroup:addChild(menuBG)   -- New game button newGameBTN = Bitmap.new(Texture.new("newgameBtn.png")) menuGroup:addChild(newGameBTN)   -- Settings button settingsBTN = Bitmap.new(Texture.new("settingsBtn.png")) menuGroup:addChild(settingsBTN)   -- Statistics button statisticsBTN = Bitmap.new(Texture.new("statsBtn.png")) menuGroup:addChild(statisticsBTN)   -- When I'm ready to unload the main menu I use this: stage:removeChild(menuGroup); menuGroup = nil

Currently, it's not possible to get the used texture memory but you can get the memory that Lua allocates:

local monitorMem = function() collectgarbage() print( "\nMemUsage: " .. collectgarbage("count") ) end   stage:addEventListener(Event.ENTER_FRAME, monitorMem)

I have to get use to the "Sprite" class. I think Sprite is like Display in Corona.

Thank atilim!
