A3 Gui editor
Hey guys,
I know it's a little bit late for a tool like this, but better late than never! I finally got tired of losing my mind manually calculating coordinates and typing out config.cpp files for custom dialogs, so I decided to put together a visual editor as a personal project.
A3L GUI Editor is just a free, web-based canvas I made to make building UI completely painless. Instead of guessing numbers in a text editor, you can just drag, resize, multi-select, and layer your controls right in your browser. It handles all the annoying Arma math for you and automatically resolves complex expressions for GUI_GRID, SafeZone, and Pixel Grid.
You don't even have to start from scratch. I packed it with 51 presets covering standard Arma and Life/RP base classes, and you can import your existing config.cpp files to just edit them visually. It respects Arma's class inheritance too, so the code it spits out is super clean and only includes the stuff you actually changed. I also added Photoshop-style tabs for managing multiple dialogs, alignment guides to snap things into place, and a way to upload PNGs so you can actually preview your textures on the canvas.
Since it’s just a web app, there's nothing to download or install. It's totally free and just something I built to make modding a bit easier.
I'll drop the link to try it out in the comments below! Let me know what you guys think, or if you run into any weird bugs.
