Game development

BIGGI combines engine-aware coding agents with a local verification loop. It can change game code, run the project, inspect scenes and runtime state, read logs, capture screenshots, execute tests or playtest scenarios, profile performance, and report evidence in the same conversation.

Choose a game agent

AgentUse it for
GameplayMechanics, input, physics, AI behavior, and entity systems
Game ArchitectRead-only design of systems, scenes, data flow, saves, and multiplayer
Tech ArtShaders, materials, VFX, and render pipelines
PerfFrame time, allocations, draw calls, loading, and profiling

Code and Debug can also work in game projects. The game-specific agents add focused instructions and Game Loop permissions.

Supported live loops

ProjectCurrent integration
UnityManaged editor bridge for run, inspect, test, screenshot, playtest, profile, build, runtime, and selected scene operations
Godot 4Editor bridge when available, with spawn-based fallbacks for supported operations
Browser gamesManaged dev server and isolated browser for run, inspect, test, screenshot, playtest, profile, and build

Unreal and other engines receive engine-aware coding help, but do not have a dedicated live Game Loop adapter in the current release.

A reliable game task

  1. Open the game project as the VS Code workspace.
  2. Select the agent that matches the work.
  3. State the engine version and the behavior you want.
  4. Ask BIGGI to inspect the existing implementation before editing.
  5. Ask it to use available Game Loop tools to verify the result.
  6. Review the code diff and the captured test, console, scene, screenshot, or profiling evidence.

Example:

Use the Gameplay agent. Add coyote time to the existing player controller without changing the input bindings. Inspect the scene and controller first, make the smallest change, then run a focused playtest and summarize the evidence.

Capability gaps are expected

An engine operation can be unavailable because the editor is not installed, the project does not meet a tool requirement, the editor bridge is not active, the environment has no display, or the adapter does not support that operation.

BIGGI should report a capability gap instead of inventing evidence. You can then install the missing dependency, open the editor, choose a fallback verification method, or review the change manually.

Work in parallel

Use Agent Manager to isolate several tasks or compare approaches. Each managed worktree can have its own branch, session, terminal, run script, and live diff.
