<h2 class="title">About AlexGames</h2>
<p>AlexGames is a platform for simple games written in Lua, Rust, or C/C++, currently supporting HTML (the page you are currently visiting), and experimental implementations in Android, and Windows/MacOS/Linux (using wxWidgets). The idea is that someone can throw together the "fun parts" of a game in a few hundred lines of Lua, Rust, or C++, and then the boilerplate to get it running on their platform of choice should be already taken care of. Adding support for a new platform should be relatively easy.</p>
<p>For further convenience (both for game developers and game players), you can develop and/or play your own Lua game just by uploading a bundle of Lua code to the browser client. If you want to put together a simple game, but don't want to bother building this project, you shouldn't need to: just download <a href="example_game_apidemo.zip">the example Lua game zip</a>, consult the <a href="game_api_doc.html" target="_blank">Lua API reference</a>, and then you can modify the existing example Lua code or write your own, and then zip your files. Then you can upload that zip file into the web client, or send it to a friend.</p>
<p>It also supports some helpful features like a built in English dictionary (for word puzzle games), sharing state via URL, and saving state and browsing previously saved states. Previews of saved states are generated using the same code the programmer wrote to render the game itself. The logic for handling this is included as a library to the game platform itself: very little extra code should be needed for game developers or developers of new "clients" (more on what a "client" is below).</p>
<p>One of the goals is for the API to be very convenient both for game developers, and for developers of new "platforms". In this context a "platform" is a device that the game is built for: there is a platform for browsers, developed in HTML/JS/WASM, a native Android platform, and a wxWidgets platform that allows for playing games natively on Windows, MacOS, and Linux.</p>
