Storyboard throws a bounch of errors....

Solar2D General Questions/Discussion
#1

Ok, I just completed my storyboard yesterday, and it seems straight forward, but I ran into problems when I added a feature to my levelselect page.

This is my code that adds several of images on the screen with small locks.

for i = 1, 10, 1 do  
 level[i] = display.newGroup()  
  
 level[i]:insert(display.newImage( "level.png" ))  
  
 local imgLock = display.newImage( "level\_lock.png" )  
 level[i]:insert(imgLock)  
 imgLock.x = 40  
 imgLock.y = 36  
  
 if(i\<6) then  
 level[i].y = screenH / 2.7  
 level[i].x = (i\*70) + 30  
 else  
 level[i].y = screenH / 1.7  
 level[i].x = ((i-5)\*70) + 30  
 end  
 level[i].tag = "level1\_" .. i  
 level[i]:addEventListener("touch", StartLevel)  
 level[i].alpha = 0  
  
 transition.to(level[i],{alpha=1,time=500})  
 group:insert(level[i])  
 end

And as soon as I switch scene the terminal gives me the following errors. I am 100% sure that it has to do with the code above.

Help, I am knee-deep into trouble here!

is that code in the createScene event handler or the enterScene event handler?

createScene must put at least one display object into group to avoid that error.

any scene file going to or coming from has to have something in group.

Hi again,

I am doing this in the enterScene handler. And I am putting the new group into the following group:

local group = self.view
…
…
…
group:insert(level[i])
as you can see in my previous post. Could there be something wrong when i am adding a new group to the group that takes care of everything?

do something like this in createScene:

local bg = display.newRect(0,0,display.contentWidth, display.contentHeight)
bg:isVisible = false
group:insert(bg)

and see if that fixes your problem.

Arghhh, stupid me - i had a loop outside my inner loop so that was not so smart :smiley:

Thanks, but your solution got me on track :wink:
