game-arch-patterns SKILL.md skillA
game-arch-patterns from hermeticormus/claude-code-game-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Game architecture code patterns: a fixed timestep loop with accumulator, an EventBus, ECS-style composition in Godot, Resource-based game data, an autoload service locator, and a game state stack. Use when laying out the core structure of a game or untangling one that has grown messy.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Game Architecture Patterns
## Fixed Timestep Game Loop with Accumulator
```gdscript
# Fixed physics timestep decoupled from variable render rate
# Based on Glenn Fiedler's "Fix Your Timestep!" (2004)
class_name GameLoop extends Node
const PHYSICS_DELTA: float = 1.0 / 60.0 # Fixed 60Hz physics
const MAX_DELTA: float = 0.25 # Spiral-of-death prevention
var _accumulator: float = 0.0
var _previous_time: float = 0.0
var _alpha: float = 0.0 # Interpolation factor for rendering
func _ready() -> void:
_previous_time = Time.get_ticks_msec() / 1000.0
func _process(_delta: float) -> void:
var current_time := Time.get_ticks_msec() / 1000.0
var frame_time := min(current_time - _previous_time, MAX_DELTA)
_previous_time = current_time
_accumulator += frame_time
# Fixed timestep physics integration
while _accumulator >= PHYSICS_DELTA:
_physics_step(PHYSICS_DELTA)
_accumulator -= PHYSICS_DELTA
# Render interpolation between previous and current state
_alpha = _accumulator / PHYSICS_DELTA
_render(_alpha)
func _physics_step(delta: float) -> void:
# Deterministic physics: same delta every time
pass

How to install
mdr add hermeticormus/claude-code-game-development/game-arch-patterns@sha256:5dfda6ac58ea05ebThe line at the top of this page pins the label git:20260930.4aecd99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
