Unity Physics
Unity Physics is a deterministic, high-performance physics simulation library built on the DOTS (Data-Oriented Technology Stack) framework for the Unity game engine. It provides realistic collision detection, rigid body dynamics, and physics-based interactions for 3D and 2D games and simulations. Unlike Unity's built-in physics system, it is optimized for large-scale, data-oriented applications with predictable performance.
Developers should use Unity Physics when building games or simulations that require high-performance, deterministic physics for large numbers of objects, such as strategy games, simulations, or VR/AR experiences. It is ideal for projects leveraging DOTS to maximize CPU efficiency and multi-threading, ensuring consistent behavior across different platforms and hardware. Use it when you need precise control over physics simulations for competitive or networked games where frame-rate independence is critical.
