I am working on a game that retrieves information from text files to construct a variety of in game objects. The architecture of my data folder looks like this:
data
data/ships
data/ships/Interceptor.txt
data/sprites
data/sprites/modules
data/sprites/weapons
data/sprites/weapons/Laser.png
data/sprites/projectiles
data/sprites/projectiles/Laser.png
data/sprites/ships
data/sprites/ships/Interceptor.png
data/weapons
data/weapons/Laser.txt
the first class to try and call a file is this:
- class Ship extends Object{
- PVector v;
- Ship target;
- String[] input;
- Boolean snapcam, piloted;
- float velocity, translation, acceleration, rotationspeed, shield, shieldregenrate;
- ArrayList weapons;
- Ship(String file){
- angle = 0;
- velocity = 0;
- translation = 0;
- weapons = new ArrayList();
- input = loadStrings("ships/" + file + ".txt"); //<<<<<<<<<<<<<<<<<<<<<<<<<<<<<*ERROR*
- sprite = loadImage("sprites/" + input[0] + ".png");
- speed = float(input[1]);
- acceleration = float(input[2]);
- rotationspeed = float(input[3]);
- shield = float(input[4]);
- shieldregenrate = float(input[5]);
- for (int i = 7; i <= 7 + int(input[6])*3; i+=3){
- weapons.add(new Weapon(input[i], float(input[i+1]), float(input[i+2]) ) );
- }
- }
when called, the following error occurs and stops the sketch:
The file "ships/Interceptor.txt" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

Trouble shooting steps I've taken so far,
*Made sure all files existed and had correct names and extensions.
*Ran test sketches to confirm I know how to use loadStrings() and that it's working.
*Made sure there are no properties of the file making it inaccessible to the sketch.
*Changed the encoding of the .txt file to UTF-8
*Restarted processing, restarted computer.
Note, I have extremely limited internet access.
Thank you for your help! :)
**additional note, when all file references are commented out of the code a null pointer exception occurs without any information on where it occurred. That did not happen previous to the files or file reading code being added.
