Unreal Game Development

Build version-pinned Unreal projects with deliberate C++/Blueprint boundaries, explicit gameplay ownership, automated tests, and release-like packaged evidence.

Use When

• The project uses Unreal Engine, Gameplay Framework, C++, Blueprints, replication, Unreal assets, or Unreal packaging.

Do Not Use When

• Multiplayer architecture is the primary decision; load online-multiplayer-and-game-backend first.
• The exact engine/plugin versions are unknown.

Required Inputs

Engine/source distribution and version, plugins, target platforms/hardware, network topology, module/asset map, performance budgets, build farm, acceptance criteria, and tests.

Workflow

1. Inspect .uproject, modules, targets, plugins, config, maps, assets, source, automation, and packaging settings.
2. Record boundaries among engine framework classes, C++ domain/components, Blueprints, data assets, subsystems, and online services.
3. Define server/client authority, replicated properties, RPC contracts, relevance/update budgets, and late-join state when networked.
4. Enforce asset naming/dependency and map/cook rules; validate redirectors and unintended hard references.
5. Add automation for pure logic, gameplay integration, multiplayer network profiles, cook/package, and target-hardware smoke tests.
6. Profile and retain packaged-build CPU/GPU/network/memory evidence; preserve symbols and manifests.

Quality Standards

• Blueprint accessibility is not a reason to hide ownership, authority, or failure handling.
• Exact APIs follow pinned official Unreal documentation, not copied book snippets.
• Editor/PIE success does not replace packaged target or network-condition testing.

Outputs

Unreal architecture and version manifest; module/Blueprint contract; authority/replication spec; asset validation report; automation results; packaged build evidence.
