Issue in showing Facebook friends scores

Wiler_Jr · June 6, 2016, 6:24pm

I’m using the following code inside my Facebook listener to show Facebook friends scores. The printTable(data) command shows the event.response table informations with no problem in the log screen, but I can’t manage to display them in the device screen.

Is there something wrong within my code?

[lua]

–…

elseif ( “request” == event.type ) then

local response = event.response

response = json.decode( event.response )

local data = response.data

printTable(data)

for i=1, #data, 1 do

friendsScoreTable[i].name = data[i].user.name;

friendsScoreTable[i].score = data[i].score;

friendsScoreText[i] = display.newText(friendsScoreTable[i].name … " " … friendsScoreTable[i].score, 0, 0, “ARIBLK”, 16);

if(i==1)then

friendsScoreText[i].x, friendsScoreText[i].y = centerX, centerY;

else

friendsScoreText[i].x, friendsScoreText[i].y = friendsScoreText[i-1].x, friendsScoreText[i-1].y+20;

end

localGroup:insert(friendsScoreText[i]);

end

[/lua]

what output does printTable actually produce? Or better yet can you do:

print( json.prettify( response ) )

and show us that output?

Rob

Wiler_Jr · June 11, 2016, 2:40am

Yes, Rob. The outputs are as follows.

Not enough, Rob?

rob · June 14, 2016, 1:50pm

What color is your background? You could be drawing black text on a black background or white text on a white background (which ever the default is). The default color for display.newText() is white unless you’ve changed it.

Rob

Wiler_Jr · June 14, 2016, 11:38pm

My background is a dark blue and display.newText() color is default.

Nothing wrong in my code? I tried printing friendsScoreText[i].text, but nothing is displayed in the debugger. Weird, isn’t it?

rob · June 15, 2016, 2:35pm

I’m surprised Corona isn’t spewing errors consider:

&nbsp; for i=1, #data, 1 do &nbsp; &nbsp; friendsScoreTable[i].name = data[i].user.name; &nbsp; &nbsp; friendsScoreTable[i].score = data[i].score;

vs.

 for i=1, #data, 1 do friendsScoreTable[i] = {} friendsScoreTable[i].name = data[i].user.name; friendsScoreTable[i].score = data[i].score;

I don’t see where you’re telling friendsScoreTable[i] that it’s supposed to hold a table.

Rob

Wiler_Jr · June 17, 2016, 4:43pm

friendsScoreTable is created in the first lines of my code as “local friendsScoreTable = {}”.
I’m gonna test your correction and feedback about it soon. Thanks.

Wiler_Jr · June 18, 2016, 4:03am

Didn’t got it to work, Rob.

The code I’ve written and the log within device that has been produced is presented in the screenshot below.

As can be seen, the text that was supposed to be store inside friendsScoreText[1] is not printed in the log screen and it’s not being displayed on my device screen as well. Yet, data within data[1] is printed without any issue.

barak.eliau · June 18, 2016, 11:28pm

Try to initialize friendsScoreText[1] as Rob suggested.

[lua]
friendsScoreText[1] = {name = data[1].user.name,
score = data[1].score}

[/lua]

Wiler_Jr · June 20, 2016, 2:03pm

It worked! You meant friendsScoreTable[1], right? haha

Now, I’ve got another issue I don’t understand.

If I call the tables as

[lua]

friendsScoreTable[1] = {name = data[1].user.name, score = data[1].score}

friendsScoreText[1] = display.newText(friendsScoreTable[1].name … "\n " … friendsScoreTable[1].score, 0, 0, “ARIBLK”, 16);

friendsScoreTable[2] = {name = data[2].user.name, score = data[2].score}

friendsScoreText[2] = display.newText(friendsScoreTable[2].name … "\n " … friendsScoreTable[2].score, 0, 0, “ARIBLK”, 16);

[/lua]

it displays the related names and scores of indexes 1 and 2.

However, if I try to generalize as I presented in my first post as

[lua]

for i=1, #data, 1 do

local friendsScoreTable = {};

local friendsScoreText = {};

friendsScoreTable[i] = {name = data[i].user.name, score = data[i].score}

friendsScoreText[i] = display.newText(friendsScoreTable[i].name … "\n " … friendsScoreTable[i].score, 0, 0, “ARIBLK”, 16);

if(i==1)then

friendsScoreText[i].x, friendsScoreText[i].y = centerX, centerY;

elseif(i>1)then

friendsScoreText[i].x, friendsScoreText[i].y = centerX, friendsScoreText[i-1].y;

end

localGroup:insert(friendsScoreText[i]);

print(friendsScoreText[1].text)

print("\n" … friendsScoreText[2].text)

end

[/lua]

only name and score of index 1 is displayed.

Wiler_Jr · June 21, 2016, 11:15am

Solved!

To be clear for all, my mistake was calling tables

local friendsScoreTable = {};
local friendsScoreText = {};

inside the for loop.

Thanks Rob and Barak.
