A high-performance 2D collision detection and physics engine for .NET, ideal for games and simulations.
Velcro Physics is a high-performance 2D collision detection system with realistic physics responses, designed for creating games, robotic simulations, or interactive UI feedback systems. It solves the problem of simulating accurate physical interactions in 2D environments, from simple platformers to complex Mars rover simulations.
Game developers and simulation engineers working with .NET or MonoGame who need a reliable 2D physics engine for real-time applications.
Developers choose Velcro Physics for its comprehensive feature set, including continuous collision detection, multiple joint types, and efficient broadphase queries, all optimized for performance in .NET ecosystems.
High performance 2D collision detection system with realistic physics responses.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements continuous collision detection with a time of impact solver, ensuring smooth and accurate object interactions even at high speeds, as highlighted in the README.
Supports convex and concave polygons, circles, and multiple shapes per body, enabling complex physical representations for games or simulations.
Uses dynamic tree and quad tree broadphase for fast AABB queries and raycasts, optimizing performance in dynamic 2D environments.
Includes revolute, prismatic, distance, and other joint types with limits and motors, allowing for detailed mechanical simulations.
Offers zero-copy integration with MonoGame via a dedicated NuGet package, simplifying setup for .NET game developers.
Requires sponsorship for commercial use and issue creation, which can limit accessibility and community engagement for open-source projects.
Marked as 'under construction' in the README, leading to potential instability, breaking changes, and incomplete features during updates.
Tightly coupled with .NET and MonoGame, making it unsuitable for projects using other frameworks like Unity or web-based engines without significant adaptation.
As a comprehensive physics engine, it requires deeper understanding of physics concepts and coding compared to simpler, more integrated solutions.
