SC Tools

This module is intended to unpack, edit and repack .sc files from Supercell games.

SC files are unpacked to disk as projects. Projects contain textures and readable configuration files. These files can be edited, and a new SC file can be repacked from a project at anytime.

For a better understanding of SC file structures, look at the files in the lib/supercell-sc directory.

This tool has been successfully tested on Brawl Stars assets from Q1 2022.

Todo:

• Add engine web example
• Check sc compression perf

Recipes

Unpack SC File(s) to Project(s)

import { basename, join } from 'path';
import glob from 'glob';
import { unpack } from '@ultrapowa/sc-tools';

const sourcePattern = 'path/to/apk/assets/e30a1e4a93c76bea755877299ebebf535e1b3d73/sc/*.sc';
const projectDir = 'path/to/local/workspace/brawl-stars-33.127';

const files = glob.sync(sourcePattern)
  .filter((filePath) => !filePath.includes('_tex.sc')); // those will be processed within the regular .sc files

for (const filePath of files) {
  const projectName = basename(filePath, '.sc');
  await unpack(filePath, join(projectDir, projectName), {
    shapeOuterColor: { // remove this options for total transparency
      red: 0, green: 255, blue: 0, alpha: 255,
    },
  });
}

Pack Project to SC File

import { pack } from '@ultrapowa/sc-tools';

await pack('path/to/local/workspace/clash-royale/spell_goblin_barrel');

Extract SC File Shapes as PNG Images

import { basename, join } from 'path';
import glob from 'glob';
import { unpack, buildPngShapes } from '@ultrapowa/sc-tools';

const sourcePattern = 'path/to/apk/**/*.sc';
const projectDir = 'path/to/local/workspace/brawl-stars-38.111';

const files = glob.sync(sourcePattern)
  .filter((filePath) => !filePath.includes('_tex.sc')); // those will be processed within the regular .sc files

for (const filePath of files) {
  const projectName = basename(filePath, '.sc');
  const projectDirectory = join(projectDir, projectName);
  await unpack(filePath, projectDirectory, { flattenShapes: true });
  await buildPngShapes(projectDirectory); // still sync
}

Export Movie Clips to Render in a Browser

This part of the code is not migrated yet.

import path from 'path';
import { exportMovieClips } from '@ultrapowa/sc-tools';

const filePath = 'path/to/apk/assets/e30a1e4a93c76bea755877299ebebf535e1b3d73/sc/level.sc'; 
const outputDir = 'path/to/workspace/rendering';

await exportMovieClips(filePath, outputDir);
