I know it’s possible to extract these files from the game with OpenIV, modify headers and extension and then decompile them with various software like Sothink SWF Decompiler or JPEXS Free Flash Decompiler to get editable ActionScript files.
But how to compile them back into swf after making changes? I know it’s possible, because people sometimes release resources with custom, modified gfx that override the originals.
To edit .gfx files, which are commonly used for game graphics or user interfaces, you’ll need a few tools depending on the specific game or software you’re working with. Here’s a general guide to help you edit .gfx files:
1. Understand the File Format
.gfx files are often used for Flash-based graphical elements in games, so they might be associated with Adobe Flash or Scaleform GFX. Some games use custom versions of .gfx, which means they require special tools to be edited.
.gfx files might contain vector graphics, textures, or even action scripts for UI elements.
2. Tools You Might Need
Depending on the format of the .gfx file, you can use one of the following tools:
JPEXS Free Flash Decompiler: This tool is used to open and decompile .gfx files based on Flash or Scaleform GFX. It allows you to edit both the graphical and scripting components of these files.
Scaleform GFx SDK: If you’re dealing with Scaleform .gfx files (commonly used in game UI development), you might need the Scaleform GFx SDK.
Note: The Scaleform SDK is a professional-grade tool used by game developers, and it may require a license.
You can use tools like Autodesk Scaleform or 3rd party utilities that are compatible with it.
Adobe Animate (Formerly Flash Professional): If the .gfx file is a Flash-based graphic, you can import it into Adobe Animate for editing.
3. Conversion to SWF
In some cases, you may need to convert .gfx files to .swf (Shockwave Flash) format, edit them, and then convert them back. Tools like FFDec (JPEXS Flash Decompiler) can help with this process:
Open the .gfx file in FFDec.
Convert the .gfx to .swf.
Edit the .swf file in a Flash editor (like Adobe Animate or JPEXS).
Convert it back to .gfx after editing.
4. Modifying Assets
Once you’ve decompiled or opened the .gfx file, you can:
Edit graphical elements: Use vector or raster graphic editing tools to modify images, icons, and textures.
Change UI elements: Adjust scripts or animations within the file to change the way elements behave.
5. Repackaging
After editing the .gfx file, you’ll need to repackage it for use in the game or software. Make sure that the modified .gfx file is saved correctly and that it’s compatible with the game engine or application you’re working with.
6. Testing
After editing and repackaging the .gfx file, test it in-game or within the software to ensure your changes are applied correctly.
If you’re working with .gfx files for a specific game, let me know which one, and I can guide you with more precise instructions for that particular case.
