Generate2dmap

Overview

Build the smallest map bundle that satisfies the game. Decide the map as a pipeline, not as a single strategy label:

1. visual_model: baked_raster | layered_raster | tilemap | layered_tilemap | parallax_layers
2. runtime_object_model: none | separate_props | y_sorted_props | interactive_entities | foreground_occluders
3. collision_model: none | coarse_shapes | precise_shapes | tile_collision | polygon_walkmesh | trigger_zones
4. engine_target: raw_canvas | Phaser | Tiled_JSON | LDtk | Godot_TileMap | Unity_Tilemap | project-native

Use user-specified parameters when present. When the user does not specify them, infer the lightest pipeline from the existing game, camera, collision needs, map scale, and editing needs.

Read references/map-strategies.md when the pipeline choice is not obvious. Read references/layered-map-contract.md before implementing a layered raster map. Read references/prop-pack-contract.md before batching generated props into a sheet.

Image Generation First

This skill is image-generation-first for visual assets. Use built-in image_gen as the default creative art source for base maps, dressed references, prop sheets, prop sprites, tileset art, parallax layers, battle backgrounds, and other visible map assets.
