But it is simple and small enough to be understood by\nenthusiasts without much effort, in a short time.\n\n## Building\nAlong with the ECS itself (which is header-only), this repo contains a little benchmark\ntool which can be build and executed. Since it doesn't depend on any libraries except\nthe C++ standard library, It can be built with most C++ toolchains out there.\n\nOn a Linux box (and generally any Unix-like box with `g++`) you can build it with\n(this includes optimizations):\n```sh\ng++ main.cpp -o a.out -O3\n```\n\nOn Windows, you should be able to build it with [MinGW](https://www.mingw-w64.org/)\nor the Visual Studio compiler.\n\n## Running\nJust run the resulting executable (It will be `a.out` if you used the command above)\nand give it the number of entities to be created for test on the standard input\n(usually your terminal). On a Unix-like shell, you can also run:\n```sh\necho N | ./a.out\n```\nWhere `N` is the number of entities for the test.\nThen, it will print the time spent on creating the entities and running some\nnear real-life queries on them. For more details, you can look inside `main.cpp`.\n\n---\nThe \"cover art\" is created using [Rnote](https://rnote.flxzt.net) and inspired by\nan image in [Skypjack](https://github.com/skypjack)'s blog post mentioned above\nand thus is distributed under\n[CC BY-NC-SA 4.0](https://creativecommons.org/licenses/by-nc-sa/4.0/).","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fovershifted%2Fsent","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fovershifted%2Fsent","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fovershifted%2Fsent/lists"}
