SC2FLA-FOSS-Edition

SC2FLA-FOSS-Edition is a Free and Open-source tool for converting .sc files (Supercell's 2D asset format) into .fla (Adobe Animate) files.

The Original SC2FLA which was released by Daniil and Fred is now closed-source and has been rewritten by Daniil in a faster language with more features.

Features

This FOSS edition builds on Daniil's last public SC2FLA version. It adds basic compatibility with newer SC formats and offers extended support for SC2FLA. It does not have advanced features from the Paid Version, but it is a usable solution for those needing basic conversion capabilities. It supports:

• Basic .sc to .fla conversion
• Minor Bug fixes
• Version detection for .sc files
• Downgrade support for SC2 to SC1 format via ScDowngrade.exe
• Decode support for SCTX format via SctxConverter.exe
• Support for batch processing of files
• Creating spritesheets via SCTex.exe (soon)
• Multithreading for way faster conversion (Only bottleneck being CPU) (soon)

Support

This tool is only usable on Windows with no plans to extend OS support. I'm improving it, but new features are not a priority at all.

For any errors, feel free to message me anytime on discord @generic_name_1911 or create an issue. Do not create issues for feature requests.

Feel free to contribute to this project! Any help is greatly appreciated :D

Dependencies:

1. Python 3.10+ (Added to PATH)
2. pip
3. ScDowngrade
4. SCTX-Converter
5. SupercellFlash Texture Tool (Modified by me)

Installation and Execution

For V1.x - V3.x

1. Install dependencies:

   pip install -r requirements.txt
   

2. Download ScDowngrade.exe and SctxConverter.exe.

3. Place both binaries into the ~\lib folder.

4. Run run.bat or execute via CLI.

For V4.x+

1. Install dependencies manually as above, or run:

   .\user-scripts\setup.py
   

   This installs dependencies and downloads the latest release of ScDowngrade.exe and SctxConverter.exe.

2. Place both binaries into the ~\lib folder.

3. Run desired scripts from .\user-scripts by dragging them to the main folder and executing:

   • setup.py — Installs dependencies and downloads latest binaries
   • process folder.bat — Converts .sc files with downgrade support
   • dump raw.bat — Dumps RAW resources
   • spritesheet.bat — Creates PNG spritesheets [V5.0+]
   • clean all files.vbs — Effectively resets the tool
