[Consider donating](https://github.com/sponsors/Genbox) to support the effort.\n\n## What is this?\nVelcro Physics is a high performance 2D collision detection system with realistic physics responses. It can be used to create games or real-time robotic simulations.\n\n## What is it good for?\nYou can create a game, robotic simulatons or even UI feedback systems using this engine and associated tools. Everything from a simple platform game to Marsrover simulations are possible.\n\n## Features\nWe have tons of features!\n\n* Continuous collision detection (with time of impact solver)\n* Contact callbacks: begin, end, pre-solve, post-solve\n* Convex and concave polygons and circles.\n* Multiple shapes per body\n* Dynamic tree and quad tree broadphase\n* Fast broadphase AABB queries and raycasts\n* Collision groups and categories\n* Sleep management\n* Friction and restitution\n* Stable stacking with a linear-time solver\n* Revolute, prismatic, distance, pulley, gear, mouse joint, and other joint types\n* Joint limits and joint motors\n* Controllers (gravity, force generators)\n* Tools to decompose concave polygons, find convex hulls and boolean operations\n* Factories to simplify the creation of bodies\n\n## Packages\nYou can use VelcroPhysics as a normal .NET library. We also have zero-copy integration with [MonoGame](http://www.monogame.net/).\n\n* [![NuGet](https://img.shields.io/nuget/v/Genbox.VelcroPhysics.svg?style=flat-square\u0026label=Library)](https://www.nuget.org/packages/Genbox.VelcroPhysics/)\n* [![NuGet](https://img.shields.io/nuget/v/Genbox.VelcroPhysics.MonoGame.svg?style=flat-square\u0026label=MonoGame)](https://www.nuget.org/packages/Genbox.VelcroPhysics.MonoGame/)\n\n## Sponsored Project\nThis is a [sponsored project](https://github.com/sponsors/Genbox). That means in order to create issues and pull requests, or use the project commercially, you must become a sponsor. Projects like this take up a lot of time and effort, so please help keeping open-source projects alive by becoming a sponsor today. You can stop your sponsorship anytime you want.","funding_links":["https://github.com/sponsors/Genbox","http://paypal.me/IanQvist"],"categories":["Physics","GameEngine Design","Libraries"],"sub_categories":["C#"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FGenbox%2FVelcroPhysics","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FGenbox%2FVelcroPhysics","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FGenbox%2FVelcroPhysics/lists"}
