Программирование на js

Оно не работает, а мне надо чтобы работало
const fs = require('fs');
const path = require('path');

// Define the root directory of the game
const rootDir = '/path/to/mindustry'; // Replace with the actual path to the Mindustry root directory

// List of valid image extensions
const imageExtensions = ['.png'];

// Array to store found textures
let textures = [];

// Function to search for textures recursively

files.forEach(file => {
const filePath = path.join(directory, file);

} else {

}
});
}

// RLE Compression Function

и ещё

}

const compressedData = rleCompress(rgbaArray);

const outputFilePath = texturePath.replace(rootDir, 'rle_textures').replace('.png', '.rle.json');

});
});
}

// Search and process all textures in the root and mods directories
searchTextures(rootDir);
searchTextures(path.join(rootDir, 'mods'));
processTextures();
