Necsus is an entity component system (ECS) library for the Nim programming language that leverages Nim’s macro capabilities to minimize boilerplate code in ECS-based applications. In Necsus, components are standard Nim types, systems are regular procedures, and entity management is abstracted away, simplifying the development process. This design approach aims to keep the cognitive load low while providing the benefits of an ECS architecture.

To define an application using Necsus, developers apply the necsus pragma to a function declaration, integrating various systems into the application’s lifecycle. Systems can be designated to execute during startup, each loop iteration, or teardown phases, offering flexibility in application behavior. This structured methodology facilitates the creation of complex, efficient applications with clear separation of concerns.

Spacial Indexing: The Adaptive Hash Grid Algorithm

I’ve been exploring spatial indexing lately, trying to find a balance performance and simplicity. While looking at the Hierarchical Spacial Grid Hash algorithm, I had a thought about how to combine its layering system with a flat spatial hash. I’ve been searching for prior art to determine if this is a “new” idea, but haven’t found any yet. I’m sharing this approach to collect feedback. For the purpose of this article, I’m calling this the Adaptive Hash Grid algorithm (AHGrid). As I said, it’s a twist on a spatial hash that incorporates the size of the object into the hash key generation. The benefit is that objects in an AHGrid will only ever be stored in a single cell within the grid, which simplifies the process of queries and updates. It’s also capable of easily storing objects of varying size spread out across a basically unbound space (low(int32)..high(int32)). ...
