{F1300 layout=right, float, size=full, alt="Echo logo"} **Echo** is a cross-platform C++ framework and game engine for mobile, desktop and consoles. It is free and open source, under the permissive [[https://en.wikipedia.org/wiki/MIT_License|MIT licence]]. The primary goals of Echo are: - Facilitate experimentation with consistent abstractions for a wide variety of platforms, toolchains and C++ standards, enabling write once core logic. - Performance is important so abstractions are designed to give target implementations the flexibility to deal with details as needed. In some situations it is possible to pre-process and prepare code and data to optimise for the target. - Enable a minimum level of graphics support that "echoes" past capabilities. This doesn't mean modern features won't be available (e.g PBR) but those won't necessarily backwards compatible. - Be modular and easy to port a subset or all functionality to new platforms without too much trouble. - Provide base functionality to enable software to run on older or unusual hardware. This often sacrifices some C++ standard features in place of platform abstractions to ensure target hardware is capable of running code. If this is not important to your then you can ignore the corresponding Echo implementations of features in place of C++ standards. Development for Echo is primarily done on a [[https://en.wikipedia.org/wiki/Linux|Linux]] PC, with deployment options for other major platforms, so that is the recommended development setup. [[http://ubuntu.com/|Ubuntu]]-based distributions are recommended. Some users have had success on other distributions though. Development on Windows can be made easier using [[https://github.com/SeanTasker/edepbuild|edepbuild]] for which there is a PowerShell version available.
