[Resolved] Issue with localGroup:insert

ht5629 · October 25, 2012, 3:17pm

First of all, I am a total noob, this is a school assignment and I have no idea what I’m doing.

The problem I have is with inserting buttonCover into localgroup, I have tried many different things, like localGroup:insert(buttonCover[totalButtons]) and localGroup:insert(button[count]). I am totally lost…

the error I get is:

Move; localGroup:insert(buttonCover); --this is the problem

to line 327 - then change to;
localGroup:insert(buttonCover[totalButtons])

I believe that should do the trick- please let me know.

That removed all errors allright, but now none of the buttonCovers show up in my game… It looks like this now:

[lua]

–Set a cover to hide the button image

buttonCover[totalButtons] = display.newImage(“button.png”);
localGroup:insert(buttonCover[totalButtons]);
buttonCover[totalButtons].x = x; buttonCover[totalButtons].y = y;
totalButtons = totalButtons + 1

–Attach listener event to each button
button[count].touch = game
button[count]:addEventListener( “touch”, button[count] )
end

end
– localGroup:insert(button);
localGroup:insert(restart);
localGroup:insert(menu);
[/lua]
This is just a new account by the way…

EDIT: So I have been trying different stuff, and whenever the error shows up the buttons show up normally and work fine, however, every time the game doesn’t find an error the buttons disappear. [import]uid: 190275 topic_id: 32330 reply_id: 128749[/import]

o2539369 · October 26, 2012, 4:11am

Okay, now I got it to work!

In addition to adding localGroup:insert(buttonCover[totalButtons]) to the line you said I added localGroup:insert(button[count]) to line 308.

So now the bottom looks like this:

for count = 1,3 do
x = x + 90
y = 20
for insideCount = 1,4 do
y = y + 90
–Assign each image a random location on grid
temp = math.random(1,#buttonImages)
button[count] = display.newImage(buttonImages[temp] … “.png”);
localGroup:insert(button[count]) --added to work
–Position the button
button[count].x = x;
button[count].y = y;
–Give each a button a name
button[count].myName = buttonImages[temp]
button[count].number = totalButtons

–Remove button from buttonImages table
table.remove(buttonImages, temp)

–Set a cover to hide the button image

buttonCover[totalButtons] = display.newImage(“button.png”);
localGroup:insert(buttonCover[totalButtons]) – added to work
buttonCover[totalButtons].x = x; buttonCover[totalButtons].y = y;

totalButtons = totalButtons + 1

–Attach listener event to each button
button[count].touch = game
button[count]:addEventListener( “touch”, button[count] )
end

end

–for countI = 0, table.getn(buttonCover)/2 do

–end

– localGroup:insert(button);
localGroup:insert(restart);
localGroup:insert(menu);

– buttonCover[totalButtons] = display.newImage(“button.png”);

return localGroup;

end

@ht5629,

Just curious, but what school are you attending and what class are you taking? I ask because I am interested in how Corona SDK is being used in schools.

I attend Høgskolen i Nord Trønderlag, Norway. Working on my bachelor in game- and experience(as in “wow, that was quite an experience”)-design. Corona is used pretty much for all mobile development along with Unity3d. This particular class is called “Multimedia and mobile devices”.

No worries, glad to help. Marking as resolved.

PS - Ed, please don’t use makeshift sigs. We will support sigs soon but for now makeshift is against guidelines; http://developer.coronalabs.com/forum/2011/05/05/forum-rules-and-guidelines - thanks.

Peach,

Thanks for the notice. I’m used to posting with signatures over at the GarageGames forums, but that’s no excuse. I should have read the guidelines.
I it looks like you or someone else has been doing some cleaning, but I found a few old posts that still have my signatures in them.
I can clean these up, but I’m afraid that doing so will move them to the ‘Active Discussions’ column which could block folks from getting attention on their threads.

Do you want me to:
A. Leave them alone,

B. Clean them myself, or

C. Leave it to you folks.

To avoid polluting the thread with more links I’ve placed the links to these files in a text file here.
3. Lastly, I am looking forward to the signature feature. It will be useful and a time saver.

Thanks again,
Ed

Hey Ed-

Sorry for the late reply, was off for the weekend.

First up - I greatly appreciate your response; thanks for understanding. I know some forums do accept this, certainly. Soon we will have a new forum and then we will have sig options.

Until then no, you absolutely don’t have to edit your old posts - if any of us see sigs like that we’ll likely snip them but we aren’t obsessive about it, especially when it’s unintentional.

Please do post your links in any thread where you can work them into the post appropriately - spreading links is just fine, just no sigs. (Soon!)

Thanks
