Software Architecture

Resources for my thinking on UI Programming, Distributed Systems Design and Video Game Architecture. Spoilers: it's the same patterns everywhere.

• Event-Driven communication

  • Limit direct interaction between components of a system

• Data-Oriented

  • Events -> Components -> Data Updates

  • Data Updates -> Components -> Events

  • Requests -> Components -> Data Queries -> Response

• Unidirectional, immutable, pure, side-effects at boundaries

  • Functional core, imperative shell

• Domain-Driven-Design

  • Carefully architect code around core business concepts

My take on video-game architecture

When considering game architecture specifically a few extra elements become relevant:

• Zero-allocation event dispatch

  • Object pooling

• Minimal-allocation state update

  • Clever immutable data structures

• Minimal-allocation projection update

  • Infrequent projection changes can allocate

  • Frequent projection changes should be computed with no allocation

• Minimal-runtime-instantiation of game entities

  • Object pooling

• Object lifecycle handling, no dangling subscriptions
