First of all, I tried to search if someone already asked the question during 1 hour and didn't find anything good for my problem, but sorry in advance if the question has already been asked.
For my games, I using folders to stock every levels made with Tiled in JSON file.
The structure is I have my root folder with my .c3p project, and all the external files I need.
What I want to do is, at Runtime, be able to load external levels depending of the situation.
For exemple if my variable "ActualLevel=6" I want to be able to load the files "Root/Levels/Level(ActualLevel).JSON".
I guess I have to use "Load URL" action, but I don't know what to write inside to have acces to root folders and check files.
Thank you in advance!
