name: hyrule-navigator description: Autonomous navigation agent for Oracle of Secrets. Uses static map data and dynamic RAM state to localize Link and route him to destinations.

Hyrule Navigator

Scope

• Localize Link in the game world (Dungeon Room or Overworld Screen).
• Plan paths between rooms (Macro-Pathing) using world_graph.json.
• Steer Link to specific coordinates (Micro-Pathing) within a room.
• Handle transitions (Doors, Stairs, Entrances).

Core Capabilities

1. Localization

Identify where Link is using RAM:

• Dungeon: RoomID ($7E00A0), X ($7E0022), Y ($7E0020).
• Overworld: ScreenID (Calc from X/Y), Global X/Y.
• Context: Indoors flag ($7E001B).

2. Macro-Pathfinding

Route from current location to a target room/screen.

• Uses world_graph.json (compiled from z3ed data).
• Returns a sequence of actions: [Go West Door, Take Stairs Up, Enter Cave].

3. Micro-Steering

Move Link to a specific pixel/tile coordinate.

• Input: Target X, Y.
• Control: PID-like loop reading RAM and pressing D-Pad.
• Safety: Checks for collisions (future) and stuck states.

Workflow

1. Where am I?
   • navigator locate -> "Room 0x1B (Dungeon), Tile (10, 20)".
2. Route:
   • navigator route --to 0x1A -> "Path: West Door -> Room 0x1A".
3. Execute:
   • navigator drive --path ... -> Autonomously moves Link.

Dependencies

• Data: ~/src/hobby/yaze/world_graph.json (Must be up-to-date with ROM).
• Tools: z3ed (for map data), Mesen2 socket CLI (for RAM/Input).
• Scripts: ~/src/hobby/yaze/scripts/ai/navigator.py.

Commands

• navigator locate: Print current localization info.
• navigator route <target_id>: Plan path to target.
• navigator goto <target_id>: Plan and execute movement.

Example Prompts

• "Where am I currently located in the game?"
• "Navigate Link to Room 0x1A from the current position."
• "Find a path to the nearest Dungeon Exit."
• "What are the neighbors of the current room?"

Troubleshooting

• "Neighbors: []": Check world_graph.json connectivity. Run map_compiler.py again.
• Localization Failed: Ensure Mesen2 socket control is running (/tmp/mesen2-*.sock). Verify RAM addresses in navigator.py match the active ROM version.
• Stuck Walking: Micro-pathing collision avoidance is primitive. Manually guide Link if stuck on complex geometry.
