Non-Unity Common Patterns

This document collects repeatable, battle-tested patterns for integrating OGAL in Unreal, Godot, web clients, backend services, and indexers.

These are not theoretical examples. They reflect how OGAL is intended to be used in production, and how teams typically structure non-Unity integrations today.

If you follow these patterns, you will:

  • Keep gameplay and UI code clean
  • Preserve upgrade flexibility
  • Get predictable, debuggable behavior
  • Make your backend and indexer workflows resilient

Pattern 1: Treat OGAL as Read-Mostly Infrastructure​

Principle
Most runtime systems should read OGAL state, not mutate it.

Why

  • Ownership and mutability rules are enforced on-chain
  • Reads are cheap and permissionless
  • Writes are intentional, explicit user actions

Recommended

  • Query OGAL manifests to verify ownership
  • Use OGAL state to gate features, not drive frame logic
  • Centralize all OGAL writes in a small number of services

Avoid

  • Calling OGAL instructions directly from game loops
  • Sprinkling manifest updates throughout the codebase

Pattern 2: Centralize Chain Writes Behind a Service Layer​

Principle
UI or gameplay code should not assemble transactions.

Why

  • Transaction composition is error-prone
  • Error handling becomes inconsistent
  • UX suffers when logic leaks into the client

Recommended

  • Web: a single transaction builder module (e.g., web3.js or wallet adapter flow)
  • Unreal/Godot: backend service that builds transactions and returns a payload for signing
  • Backend: a dedicated mint/update service with clear interfaces

Avoid

  • Building transactions in UI widgets or gameplay scripts
  • Duplicating PDA derivations across multiple clients

Pattern 3: Explicit User Actions for All Writes​

Principle
Every on-chain write must correspond to a clear user action.

Why

  • Wallet prompts are disruptive
  • Silent writes break trust
  • Retry semantics are explicit by design

Recommended

  • Tie writes to buttons, confirmations, or editor actions
  • Surface signing status and failures in UI
  • Persist transaction intent in logs or a job queue

Avoid

  • Background writes
  • “Auto-save” behavior that triggers transactions
  • Retrying writes without user confirmation

Pattern 4: Separate On-Chain Truth from Off-Chain Metadata​

Principle
Do not assume metadata drives gameplay directly.

Why

  • Metadata is off-chain
  • Gateways can degrade
  • Runtime assets must be validated

Recommended

  • Treat OGAL manifest hash as the source of truth
  • Validate metadata before using it
  • Cache reconstructed assets locally when appropriate

Avoid

  • Pulling JSON every frame
  • Trusting metadata without hash validation

Pattern 5: Use Indexers for Scalable Reads​

Principle
RPC reads are good for verification; indexers are better for analytics and bulk queries.

Why

  • RPC rate limits are real
  • You will eventually need historical queries
  • Latency matters for player-facing flows

Recommended

  • Subscribe to ObjectMinted and ManifestUpdated events
  • Maintain a lightweight asset table keyed by manifest PDA + mint
  • Use your indexer for search, filters, and feeds

Avoid

  • Full account scans on every page load
  • Depending on RPC for large historical queries

Pattern 6: Make Failures First-Class Outcomes​

Principle
A failed transaction is a valid result, not an exception.

Why

  • Users reject signature requests
  • Network conditions vary
  • Chain state can change between compose and submit

Recommended

  • Model results as:
    • Success
    • User rejected
    • Network failure
    • Validation failure
  • Surface errors clearly to the UI or logs
  • Let users decide when to retry

Avoid

  • Catch-and-ignore patterns
  • Automatic retry loops in gameplay code

Pattern 7: Share PDA Derivation Logic​

Principle
All clients should derive PDAs in one canonical way.

Why

  • PDA seed mismatches are the #1 source of integration bugs
  • Multiple languages can drift if logic diverges

Recommended

  • Put PDA derivation in a shared library (Rust/TS) or a backend API
  • Add unit tests that validate known PDAs from the Protocol Identity

Avoid

  • Re-implementing PDA derivations in every client without tests

Pattern 8: Configuration Over Hardcoding​

Principle
Everything that can vary should live in configuration.

Examples

  • RPC endpoints
  • Program IDs per environment
  • Rate limits
  • Retry policies

Why

  • Faster iteration
  • Safer updates
  • Easier environment switching

Avoid

  • Hardcoded RPC URLs
  • Magic numbers in mint flows
  • Environment-specific logic in code

Pattern 9: Ship a Thin Vertical Slice First​

Principle
Prove one full flow before expanding.

Recommended first slice

  1. Fetch and decode an OGAL manifest
  2. Verify ownership
  3. Load metadata and validate hash
  4. Update a manifest via a user action
  5. Confirm the update via indexer or RPC

Why

  • Surfaces real constraints early
  • Validates assumptions
  • Prevents architectural drift

Summary​

If you remember nothing else:

  • OGAL is truth, not logic
  • Writes are explicit
  • Failures are visible
  • Indexers are your scale layer
  • PDA derivations must be shared

Follow these patterns and the system will stay predictable, debuggable, and scalable as your project grows.
