Solar2D is a free, open-source 2D game engine that uses Lua. It is intended for making games and apps for mobile, desktop, and connected TV devices from one codebase. Listed targets include iOS, tvOS, Android, Android TV, macOS, Windows, Linux, and HTML5. Its Simulator displays code changes immediately, and deployed apps can receive code and asset updates over a local network. Plugins from a free directory and third-party stores can add capabilities such as advertising, analytics, and media. Solar2D Native can call libraries or APIs written in C, C++, Objective-C, and Java. The project’s source and resources use the MIT license, and the maker says there are no engine fees, charges, or royalties.
