Brody — Your Game Dev Homie

Meet Brody, Your Game Dev Homie.

Brody is an in-editor AI game development agent for Unity that understands your scenes, scripts, and project assets—enabling you to plan, build, and verify changes directly inside the Editor.

IMPORTANT: Brody Cloud requires a Brody account, internet connection, and uses credit-based metering. Asset Store purchasers receive 3 months of Brody Cloud Pro with 30,000 BC/month plus lifetime BYOK access. Third-party provider charges may apply when using BYOK.

External chat workflows often require developers to manually transfer project context between Unity and the assistant. Brody works directly inside Unity with access to the project context needed for the requested task: it reads your active scene graph, wires serialized references, batches multi-object hierarchy setups, and compiles C# through an in-memory Roslyn compiler gate before saving files to disk.

Key Capabilities

1. Roslyn In-Memory Compile Gate & Autonomous Self-Healing

Every generated script is compiled and validated in memory before touching your Assets directory. If a compiler diagnostic occurs (such as CS0103, CS0246, or missing namespaces), Brody detects the diagnostic, applies targeted repairs, and re-verifies the fix automatically without locking the editor in compilation loops.

2. Live Scene Graph & Hierarchy Automation

Control your active scene hierarchy through natural instructions. Brody inspects existing GameObjects, instantiates prefabs, adjusts transforms, attaches components, and configures materials in batches. All scene operations integrate directly with Unity's native

Undo system (Ctrl+Z).

3. Dependency-Aware C# Architecture & Refactoring

Brody scans existing scripts, custom namespaces, and MonoBehaviour signatures to understand how your classes interact. When refactoring existing code or adding new mechanics, it preserves public APIs, maintains serialized fields, and respects established coding conventions to prevent breaking dependent systems.

4. Visual Code Diffs & Checkpoint Rollbacks

Every modification creates an isolated atomic snapshot under .brody/backups/. Review line-by-line additions and deletions directly in the editor before accepting changes, with instant one-click rollback if you wish to revert to any previous checkpoint.

5. Real-Time Console Diagnostics & Error Debugging

Brody connects directly to the Unity Editor console. When runtime exceptions, null references, or obsolete API warnings occur, Brody reads the full stack trace, identifies the offending lines across your scripts, and proposes tested solutions.

6. Physics, Camera & Gameplay Systems Setup

Quickly scaffold complex gameplay assemblies. Brody can configure CharacterControllers, Rigidbody physics, joint constraints, raycast ground checks, Cinemachine/review cameras, and player input hooks with verified component wiring.

7. Render Pipeline Intelligence

Brody automatically detects whether your project runs on the Built-in Render Pipeline, Universal Render Pipeline (URP), or High Definition Render Pipeline (HDRP), preventing pipeline-specific shader, post-processing, and lighting mismatches.

8. Multi-Camera Scene Review & Spatial Verification

Brody can spawn temporary scene cameras at designated coordinates to capture rendering passes from multiple angles, verifying that geometry placement, scale, and lighting align with your spatial intentions.

9. Texture & Sound Prototyping Labs

Includes built-in generative labs for rapid prototyping: generate PBR textures directly configured into ready-to-use Unity Materials, or create prompt-based sound effects exported as native .mp3 AudioClips with 15 built-in presets.

10. Assembly Reload & Domain Resilience

Designed specifically for Unity's domain reload lifecycle. Brody persists task state across C# assembly reloads, verifying scene post-conditions and resuming active execution plans without losing context or dropping operations.

Technical Stack & Architecture

Brody is engineered as a production-grade Unity extension with zero external environment requirements:

• Engine Layer: 100% native C# package (Decnet.BrodyAI.Editor). Zero Python environments, pip packages, virtualenvs, or background daemon processes.

• Compiler Layer: Microsoft Roslyn C# syntax trees and diagnostic analyzers running in-editor for pre-save validation.

• Scene Mutation Layer: Deep integration with Unity's Undo, PrefabUtility, SerializedObject, and SceneManager APIs for non-destructive operations.

• Dual Inference Pipeline:Cloud Engine: High-throughput hosted reasoning cluster with streaming SSE delivery.

• BYOK Engine: Client-side direct HTTP/REST pipeline communicating directly with provider endpoints.

• Local Storage & State: Local EditorPrefs storage for API credentials, atomic .brody/backups/ directory for rollback history, and lightweight session cache in Library/BrodyAI/.

Dual Mode: Cloud Pro + Lifetime BYOK

Choose the workflow that fits your project requirements:

• Brody Cloud (Founder's Pro Included):Zero-setup hosted reasoning cluster. Asset Store purchasers receive 3 months of complimentary Brody Cloud Pro with 30,000 Brody Credits (BC) per month (90,000 BC total allowance).

• BYOK (Bring Your Own Key):Direct local inference using your own provider credentials. Fully supported providers include Anthropic Claude (3.5 / 3.7 Sonnet), OpenAI (GPT-4o, o3-mini), Google Gemini (1.5 Pro, 2.0 Flash), DeepSeek (V3, R1), Groq, local offline models via Ollama and LM Studio, and custom OpenAI-compatible endpoints.

Privacy, Performance & Compliance

• Strict Editor-Only Assembly: Isolated under Decnet.BrodyAI.Editor. Brody has zero runtime footprint and adds 0 bytes to standalone player builds.

• Local Key Security: In BYOK mode, API keys are stored in Unity's local EditorPrefs on your workstation. Keys are never transmitted to Decnet servers.

• Offline Development: Local inference is supported through Ollama and LM Studio after initial account and entitlement setup.

• Transparent Quota Metering: Cloud credit balance is displayed in real time in the editor status bar. BYOK mode consumes zero cloud credits.

• Opt-in Telemetry: Optional analytics and telemetry are opt-in and can be disabled at any time.

• Data Privacy Protection: Brody only processes project context required for requested functionality and does not use customer project data to train general-purpose models without explicit consent.
