SFML Games

Small C++ gameplay prototypes used to explore rendering loops, input handling, and mechanics outside an engine framework.

Systems experiment

C++ / SFML

Video evidence / These studies isolate low-level game-loop and interaction fundamentals from Unreal-specific tooling.

Engineering question

What becomes explicit when rendering, input, and gameplay loops are built without an engine framework?

Focus

  • Render loops
  • Input
  • Gameplay mechanics

The technical question

What was being tested

What becomes explicit when rendering, input, and gameplay loops are built without an engine framework?

Implementation notes

What I built

  1. 01

    Frame loop

    The experiments separate update and render responsibilities so frame-by-frame behaviour stays visible in the code structure.

  2. 02

    Input handling

    Player intent is handled directly through SFML rather than through Unreal input abstractions.

  3. 03

    Mechanics studies

    Small playable interactions keep the focus on loop ownership and feedback rather than on production asset scope.

System map

The working path

A compact model of the relationships this experiment was designed to make explicit.

  1. 01

    Window events

  2. 02

    Input state

  3. 03

    Gameplay update

  4. 04

    Frame render

Evidence and limits

What this proves

These studies isolate low-level game-loop and interaction fundamentals from Unreal-specific tooling.

These are small systems exercises, not a production engine or a claim of feature parity with the Unreal projects.

Next iteration

Take one mechanic through a longer play session with frame-time instrumentation and a small test harness.
