Ground Zero Biome Resource Pass

The Ground Zero map now has a first pass of biome-appropriate natural resources based on the selected tile's coastal California scrub/woodland biome, terrain height, slope, and drainage-candidate analysis.

Resource Types

• Wood: scrub/woodland and hillside patches.
• Fiber: grassland, scrub, and drainage-candidate areas.
• Edible plants: coastal scrub, grassland, and drainage-candidate forage patches that yield the MVP food item.
• Stone: slope, exposed terrain, and valley-edge areas.

Freshwater is separate from depleting resource nodes. Ground Zero uses BP_FreshWaterSource, an interactable water actor that restores thirst through the survival component.

Implementation

• Added BP_StoneResourceNode through Scripts/setup_playable_blueprints.py.
• Added BP_EdiblePlantResourceNode through Scripts/setup_playable_blueprints.py.
• Updated Scripts/setup_ground_zero_demo_map.py to place deterministic Ground Zero resource nodes.
• Added Scripts/verify_ground_zero_resources.py to validate node presence, yield item IDs, and remaining harvests.
• Freshwater placement and interaction are covered by Scripts/verify_ground_zero_water_source.py and Scripts/verify_water_gathering_interaction.py.

Counts

The map now contains:

• Wood nodes: 4
• Fiber nodes: 5
• Edible plant nodes: 3
• Stone nodes: 4

These counts include the original demo wood and fiber nodes so the first player path remains intact while expanding the broader tile resource layer.

Respawn Rules

MVP respawn rules separate renewable surface resources from nonrenewable stone:

• Wood nodes respawn after 900 seconds once fully depleted.
• Fiber nodes respawn after 600 seconds once fully depleted.
• Edible plant nodes respawn after 1200 seconds once fully depleted.
• Stone nodes do not respawn in the MVP.

Respawn restores the node to its configured MaxHarvests value and re-enables visibility/collision through the same replicated depletion state used by gathering.

Follow-Up

Future passes should replace the prototype meshes with real coastal scrub, grass, rock, and woodland assets, then drive density from land-cover and hydrography data instead of fixed authored points.
