Put a random icon on the screen.

(1/4) > >>

iOtero:
To put on the screen of my layout a certain icon of the path / icons, I use the following code:


--- Code: ---
local icon = fe.add_image("icons/icon01.png", flx*0.215, fly*0.025, flw*0.1, flh*0.08);
icon.preserve_aspect_ratio = true;
icon.trigger = Transition.EndNavigation;


--- End code ---

And it works perfectly.
   
But what I want is to put on the screen any of the icons contained in /icons in a random way, that comes out any of those that are inside /icons.

But I do not know how to do it. And I do not find anything either. Somebody could help me?

Sorry for my bad english.

Thanks in advance.

I created a random function.

Pass array length. It return number. Use it as index in array to update image on your transition.

Okay thank you very much.
But, I'm not an expert programmer.

I tried this, but it does not work for me:


--- Code: ---fe.load_module( "module-master" );

// Posters
local my_film = randInt(6);

local film = fe.add_image("posters/films/[my_film].png", 0, 0, flw*0.4, flh*0.3);
film.preserve_aspect_ratio = true;
film.trigger = Transition.EndNavigation;


--- End code ---

Being 1.png, 2.png, etc. my film icons.

And I do not know what I'm doing wrong ... I'm sorry.

Edit:

The module.nut I downloaded it from here:
://github.com/keilmillerjr/helpers-module

I have copied the module "module.nut"  in "E:\arcade\attract\ modules", renaming it "module-master.nut".

keilmillerjr:
Break your string and insert the variable and then continue the string.

Too many languages I do and stressed out at work. Format either “str” . var . “str” or substitute the periods for plus signs.

If you can’t figure it out, I’ll do you up a chunk of code to try - tonight.

Solved:


--- Code: ---local my_film = randInt(6);
my_film = my_film.tostring() + ".png";
local film = fe.add_image("posters/films/" + my_film, 0, 0, 0, 0);

--- End code ---

Thank you very much.
