Mc Map Update

Minecraft Map Update Tool

Converts ephemeral observation data into persistent spatial memory. Updates the cell-based SpatialMap with observation data from mc-observe-blocks.

Purpose

Store observation data from mc-observe into persistent spatial memory. Cell data supports spatial queries for planning. Automatically checks if current location is already mapped before observing.

Input

• observation: Observation data from mc-observe (optional - if not provided, automatically invokes mc-observe)
• radius or blocks_radius: Optional radius for mc-observe (default: 7, only used when observation is not provided)
• x, y, z: Optional coordinates (extracted from observation if not provided)

Output

Returns uniform_return format with:

• value: Summary text of update
• data: Structured result with:
  • location: {x, y, z} block coordinates
  • spatial_map: {cells_updated, total_cells, bounds}

Behavior & Performance

• If no observation is provided, automatically invokes mc-observe internally
• Populates cell schema from observation: support, surface, hazards, resources, observability, waypoints
• Updates observer cell (direct), forward cell (inferred), and neighbor cells (obstructions)
• Auto-saves SpatialMap after each update
• Coordinates rounded to block integers

Data Storage Philosophy:

• Stores only absolute properties: support_y (absolute Y coordinate), walkable, drop (has pit below)
• Does NOT store agent-relative data: blocked, step_up, step_down, delta_y_from_agent are computed at query time
• Stores raw obstruction data (obstructions.blocks_at_y) for query-time blocking computation
• Resources/hazards only recorded when on surface (Y = support_y or support_y + 1)

Cone-Based Visibility Impact:

• mc-observe uses a forward view cone (yaw ±60°, pitch -60..+90) with line-of-sight, so surface blocks behind taller obstacles may be occluded
• Observer cell and forward cell always have support_y (from downward probes, not affected by occlusion)
• Distant cells may be created from nearby_blocks but lack support_y if their surface blocks are occluded
• Cells without support_y cannot have resources/hazards recorded (requires surface Y coordinate for validation)
• This is expected behavior: incomplete data for occluded cells until observed from another angle

Guidelines

• Can be called directly without observation - will automatically invoke mc-observe-blocks if needed
• Or call after mc-observe-blocks to persist spatial knowledge from a specific observation
• Cell data enables spatial queries via mc-map-query
• Visualization via mc-map-visualize shows mapped cells
• Clear map via FastAPI Controls panel removes SpatialMap

Usage Examples

Update automatically (invokes mc-observe internally):

{"type":"mc-map-update"}

Update with custom radius:

{"type":"mc-map-update","radius":5}

Update from existing observation:

{"type":"mc-map-update","observation":"$obs"}

With explicit coordinates:

{"type":"mc-map-update","observation":"$obs","x":-112,"y":71,"z":-123}
