…application/x-www-form-urlencoded if it has traditional post data added. This was added because Universal Game Translator needed it for DeepL support. Should probably add a way to override with any desired content-type tag someday

Seth's GL/GLES messy multi-platform C++ game SDK. Can output to Windows, Linux (including the Raspberry Pi), HTML5, OS X, iOS, Android

A component based toolbox of useful things built up over the last ten years. Instead of a giant .lib you link only the .cpp files used when possible to simplify multiplatform support as well as keep code size down.

It's kind of an SDL-like on steroids (while also being able to target SDL2 for setup/input/audio itself when needed) but generally gets the best results with its own native implementations of things. For example, it can target the following audio subsystems: SDL2_mixer, Audiere, FMOD, FMODStudio, Native iOS, Native Android, Denshion, Native Flash

It's designed with a "Write stuff in Windows with Visual Studio 2017, then compile/export to other platforms as needed" mentality.

Deprecated platforms no longer actively supported: Flash, BBX, WebOS

Some things written with Proton:

  • Growtopia - 2D MMO, a good example of using Proton's GUI for many screen sizes.
  • Dungeon Scroll - A word game. (HTML5 version)
  • Dink Smallwood - Good example of porting old code to Proton to add touch controls and multiplatform support. Open source. HTML5 version
  • Mind Wall - 3D puzzle game
  • Tanked - 3D multiplayer tank combat game including four player split screen support as well as internet match making.
  • Arduboy Simulator - Allows you to write and debug Arduboy apps with MSVC as well as output HTML5 playable versions (included with Proton SDK) HTML5 Example game
