What is Mischief? Mischief has various meanings. It can be a group of rats. Or it can refer to being naughty and playful. This Mischief, however, is an open-source ECS Game Engine! In other words... Mischief :: Entity -> Component c => System () Mischief takes great inspiration from Bevy and Flecs, and was written in 100% Haskell, taking advantage of its great ergonomics and strong type system. It is a refreshing spin on the functional and data-driven paradigms. Package This package contains only mischief-ecs, the ECS at the core of Mischief. Other packages, such as mischief-input, mischief-assets, mischief-render are planned, but haven't yet been developed to the same level as the ECS itself. Design Goals These are the main design goals of Mischief: Ergonomic and Accessible . Mischief's main purpose is to provide a very clean, intuitive, inherently opinionated, high-level API. This is the main way we differentiate ourselves from other ECS's. Learning to use Mischief should be a painless and intuitive process. Functional and Data Driven . We strive to find a balance between functional programming and data-driven design. These are two concepts that don't interact very often, but that both stand at the core of Msichief. Modular . Mischief is meant to be modular, allowing you to plug packages in and out, whether they are made by us or a third party. Highlights Here are some highlights of Mischief: Highly Dynamic . Want to disable a system? Despawn it! Fancy Queries . Complete with transitive queries and filters. Quasi-Queries . Scripting language for writing queries. Rich Systems . Monadic Systems? Yes please. Book . Mischief has its very own book! See below. Relationships . Bob Likes Charlie. Events . And much much more.. Performance Performance-wise, Mischief still has a long way to go; there are many easy performance gains that we have just been too busy to implement, as we've been mostly focusing on ergonomics, modularity, and ease-of-use. This is a pretty strong Archetype ECS however, and it is possible to bring it to about the same asymptotic performance as Bevy or Flecs, although there will probably always be a layer of indirection (or 20) that makes it a bit slower, due to the high-level, boxed, nature of Haskell.
