Description

Jan Mróz publishes a beginner-friendly Verlet integration template on Procedural Pixels for building a custom stylized physics engine in Unity over roughly one evening.

The guide defines sphere state with previous and current positions plus radius, orders velocity integration, dynamic sphere-sphere collisions, optional distance constraints for ropes or cloth, and static collider resolution, comparing the minimal feature set to Unity's built-in rigid bodies.

Beginners and jam developers who want soft bodies, chains, or stylized motion without PhysX complexity are the intended readers; no advanced math beyond vectors is required.

It is a single tutorial article with step-by-step Unity implementation guidance and links to community Verlet cloth references, offered free on the blog.

The post is a common entry point on Procedural Pixels for developers prototyping lightweight simulation before adopting the author's more advanced SDF and grid-culling articles.
