fac-nearest

name	fac-nearest
description	Find the nearest resource in Factorio — iron-ore, copper-ore, coal, stone, water, wood — within 500 tiles of your character. Use when you need ore/fuel and don't know where a patch is; fac-observe then shows the patch details once you're near.
args	{"resource":"required string — \"iron-ore\" (or \"iron\"), \"copper-ore\", \"coal\", \"stone\", \"uranium-ore\", \"water\", \"wood\""}

fac-nearest

Nearest-resource scan via the game bridge (500 tiles around your character).

Behavior

• Returns the position of the closest matching resource tile and its distance from you. Walk there (fac-walk), then fac-observe to see the patch's extent and size, then fac-harvest or place a miner.
• "iron", "copper", "uranium" are accepted shorthand for the -ore names.
• Errors if nothing matches within 500 tiles.
