Hi again,

I have two other beginner questions please :roll: .

1)When you have two .brs files in the source folder, can you use the objects created in one file in the other?

I have a main.brs, with a Main() function that ends like this :

print "my_array"
print my_array
return my_array
Second()
end sub

Then i have a second .brs file, which starts like this :

Sub Second()
	print "my_array"
	print my_array

On the debugger console, I see :

my_array
1
2
3
4
5

my_array
<UNINITIALIZED>

The Second() function is called, so I think that the "return my_array" of the Main() has been done, but it doesn't want to print the array. Is there a special way to take an object from another file, or do I have to create all the functions that will use the array in the same .brs file?

2) Is it possible to return more than one object? For example if I create two arrays in my main(), can i use :

return my_array
return my_second_array

or

return my_array ; my_second_array

(or use a "," instead of the ";")

?

Thank you

Edit : I tried to copy the function Second() under my function Main() and deleted the second .brs file, but it wasn't called this time, as the debugger console stopped after printing "1 2 3 4 5" this time.
So i set it as it was the first time, with two files, and now the Second() function isn't called anymore :cry:

The variable is only available in the scope it was created, so once you left the method it was no longer available. You can pass the variable as a parameter and update it, then the new values will come back, or you can set it up as a function that returns the variable. Another option is to look into the global "m", but in any programming language you should be careful when using global variables.

My Main() function already returns the array.
Or i didn't understand what you're telling me?

You mean to change my Main() to Main(roArray my_array) as object?

[SkipFire]

Specific to your function you will want something like:

Sub Main()
MainArray = Second()
End Sub

Function Second() As roArray
MyArray = new roArray
dostuff
return MyArray
End Function

OR

Sub Main()
MainArray = new roArray()
Second(MainArray)
End Sub

Sub Second(MyArray As roArray)
dostuff
End Sub

If the main function hits a return, it will exit the channel. What you really want is:

sub main()
my_array=[1]
my_array=second(my_array) 'pass my_array to the second function and get the altered array back.
print my_array
stop
end sub

function second(my_array as object) as object
for i=2 to 5
my_array.push(i)
return my_array
end for
end function

you have to explicitly pass the array to the function and explicitly return the array back to the calling function.

It doesn't matter which .brs file a function is in, they are all treated as if they are in the same file. Sub main is the first subroutine that is called when a channel is launched and when sub main() exits, the channel exits.

Perfect, I also managed to divide the array in three smaller arrays thanks to this method 😄 .
Thank you very much.

As an extra note, the channel will also exit once there are no more open screens even if there is code left in the method.

Hello,
Guess who has another beginner question :roll:

I have created a SpringBoard like this :

o = CreateObject("roAssociativeArray")
    o.Title = title
    o.Description = description
    o.SDPosterUrl = sdposterurl
    o.HDPosterUrl = hdposterurl
    o.ReleaseDate = releasedate

My problem is that though I haven't defined the starRating, I still have the stars on the screen. They are all grey, but still here. Is it possible to remove them or to put them white so that they would become invisible?

Thank you.

Use SetStaticRatingEnabled(false). Many of the other fields will just not show if there is no value in them.
