Donchitos ad540fe75d Game Studio Agent Architecture — complete setup (Phases 1-7)

48 coordinated Claude Code subagents for indie game development:
- 3 leadership agents (creative-director, technical-director, producer)
- 10 department leads (game-designer, lead-programmer, art-director, etc.)
- 23 specialist agents (gameplay, engine, AI, networking, UI, tools, etc.)
- 12 engine-specific agents (Godot, Unity, Unreal with sub-specialists)

Infrastructure:
- 34 skills (slash commands) for workflows, reviews, and team orchestration
- 8 hooks for commit validation, asset checks, session management
- 11 path-scoped rules enforcing domain-specific standards
- 28 templates for design docs, reports, and collaborative protocols

Key features:
- User-driven collaboration protocol (Question → Options → Decision → Draft → Approval)
- Engine version awareness with knowledge-gap detection (Godot 4.6 pinned)
- Phase gate system for development milestone validation
- CLAUDE.md kept under 80 lines with extracted doc imports

Unreal Engine 5.7 — Deprecated APIs

Last verified: 2026-02-13

Quick lookup table for deprecated APIs and their replacements. Format: Don't use X → Use Y instead

Input

Deprecated	Replacement	Notes
`InputComponent->BindAction()`	Enhanced Input `BindAction()`	New input system
`InputComponent->BindAxis()`	Enhanced Input `BindAxis()`	New input system
`PlayerController->GetInputAxisValue()`	Enhanced Input Action Values	New input system

Migration: Install Enhanced Input plugin, create Input Actions and Input Mapping Contexts.

Rendering

Deprecated	Replacement	Notes
Legacy material nodes	Substrate material nodes	Substrate is production-ready in 5.7
Forward shading (default)	Deferred + Lumen	Lumen is default in UE5
Old lighting workflow	Lumen Global Illumination	Real-time GI

World Building

Deprecated	Replacement	Notes
UE4 World Composition	World Partition (UE5)	Streaming large worlds
Level Streaming Volumes	World Partition Data Layers	Better level streaming

Animation

Deprecated	Replacement	Notes
Old animation retargeting	IK Rig + IK Retargeter	UE5 retargeting system
Legacy control rig	Control Rig 2.0	Production-ready rigging

Gameplay

Deprecated	Replacement	Notes
`UGameplayStatics::LoadStreamLevel()`	World Partition streaming	Use Data Layers
Hardcoded input bindings	Enhanced Input system	Rebindable, modular input

Niagara (VFX)

Deprecated	Replacement	Notes
Cascade particle system	Niagara	Cascade is fully deprecated

Audio

Deprecated	Replacement	Notes
Old audio mixer	MetaSounds	Procedural audio system
Sound Cue (for complex logic)	MetaSounds	More powerful, node-based

Networking

Deprecated	Replacement	Notes
`DOREPLIFETIME()` (basic)	`DOREPLIFETIME_CONDITION()`	Conditional replication for optimization

C++ Scripting

Deprecated	Replacement	Notes
`TSharedPtr<T>` for UObjects	`TObjectPtr<T>`	UE5 type-safe pointers
Manual RTTI checks	`Cast<T>()` / `IsA<T>()`	Type-safe casting

Quick Migration Patterns

Input Example

// ❌ Deprecated
void AMyCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) {
    PlayerInputComponent->BindAction("Jump", IE_Pressed, this, &ACharacter::Jump);
}

// ✅ Enhanced Input
#include "EnhancedInputComponent.h"

void AMyCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) {
    UEnhancedInputComponent* EIC = Cast<UEnhancedInputComponent>(PlayerInputComponent);
    if (EIC) {
        EIC->BindAction(JumpAction, ETriggerEvent::Started, this, &ACharacter::Jump);
    }
}

Material Example

// ❌ Deprecated: Legacy material
// Use standard material graph (still works but not recommended)

// ✅ Substrate Material
// Enable: Project Settings > Engine > Substrate > Enable Substrate
// Use Substrate nodes in material editor

World Partition Example

// ❌ Deprecated: Level streaming volumes
// Load/unload levels manually

// ✅ World Partition
// Enable: World Settings > Enable World Partition
// Use Data Layers for streaming

Particle System Example

// ❌ Deprecated: Cascade
UParticleSystemComponent* PSC = CreateDefaultSubobject<UParticleSystemComponent>(TEXT("Particles"));

// ✅ Niagara
UNiagaraComponent* NiagaraComp = CreateDefaultSubobject<UNiagaraComponent>(TEXT("Niagara"));

Audio Example

// ❌ Deprecated: Sound Cue for complex logic
// Use Sound Cue editor nodes

// ✅ MetaSounds
// Create MetaSound Source asset, use node-based audio

Summary: UE 5.7 Tech Stack

Feature	Use This (2026)	Avoid This (Legacy)
Input	Enhanced Input	Legacy Input Bindings
Materials	Substrate	Legacy Material System
Lighting	Lumen + Megalights	Lightmaps + Limited Lights
Particles	Niagara	Cascade
Audio	MetaSounds	Sound Cue (for logic)
World Streaming	World Partition	World Composition
Animation Retarget	IK Rig + Retargeter	Old Retargeting
Geometry	Nanite (high-poly)	Standard Static Mesh LODs
