Loading/Iterating through an images folder to store in a table

Solar2D General Questions/Discussion

Hello!

I’m relatively new to Corona SDK development, but have been working exclusively in iPhone dev for roughly 2 years now…

So, here’s my question!

I’m trying to create a slideshow that loads screenshots for a movie.

I want to code my class file so that it automatically counts the “Images” folder and then iterates through the images into the slideshow.

How would I begin to approach that using Lua and the Corona SDK?

Thank you very much for your help! :smiley: [import]uid: 10211 topic_id: 16975 reply_id: 316975[/import]

You would simply iterate through every image filename found in the folder and assign them to a table.

@Danny, that is interesting, how do you enumerate the files in a directory using CoronaSDK?

I can provide a proper example in a few hours.

But basically you would use lua’s io library to read the contents of a folder [import]uid: 84637 topic_id: 16975 reply_id: 63671[/import]

oh that will be wonderful… I know of ways to make it work but requires c extensions, pure lua code that runs in CoronaSDK sandbox will be so awesome.

Each day is such a learning…

My way to manage this would be to have a list of the files that are included with the app and everytime a new file is added or removed, that list is updated, so I would just read that list and know the file that exist.

if it can be dynamically enumerated as you say, that will be wonderful…

cheers,

Hey Danny,
Thank you for your help so far!

By any chance, did you get around to writing that example? I’d like to see it, if you don’t mind. :slight_smile:

I realize this isn’t a feature request, but I just wanted to add a +1!

It would be great to preload assets without having to hardcode them in. [import]uid: 49447 topic_id: 16975 reply_id: 64086[/import]

+1 one here.
Danny, have you been able to figure this out, or any other way to read the contents of documents directory ?
