Corona SDK：Director类和分组对象

Question

I've got a problem about Director class and grouping some objects on an external class. Here is my scripts of short example application.

main.lua

gameScene.lua

fakeScene.lua

theClass.lua

Do not be lazy to glance, scripts are very short :)

At the bottom of "theClass.lua" script, there is a line like that : "theGroup:insert(back)"

When I comment this line, there is no problem about application, but I need to group some objects in this theClass module. How can I fix this problem?

Thanks a lot!

Answer 1

Try returning the variable into a table using

local function theFunc(localGroupValue)
 localGroup = localGroupValue
 local back = display.newImage("background.png")
 back:setReferencePoint(display.TopLeftReferencePoint)
 back.x = 200
 back.y = 200

 return("back")

end

for s=1,#array do
 table.insert(array,theFunc())
end

and then insert the array into the group using

for s=1,#array do 
 theGroup:insert(array[s])
end
