lazyrts

RTS in a terminal. Like AOE2 shrunk down until only the important parts are left.

Two resources. Two unit types. Five buildings. No ages, no tech tree, no save files.

Build & Run

zig build          # compile
zig build run      # play
zig build test     # run tests

Zig 0.16.0. libvaxis fetched automatically.

Controls

Key	Action
hjkl / arrows	Move cursor
Tab	Cycle own units
Shift+Tab	Cycle own units (reverse)
n / N	Cycle own buildings
G	Gather at cursor
Shift+G	Auto-find nearest resource (W/D/F)
c	Jump to coordinate
M	Move selected unit(s)
T	Train worker at TC
W	Select idle workers
R	Resow fallow farm (selected/cursor)
Shift+dir	Add unit to selection
?	Toggle help overlay
Q / Ctrl-C	Quit

The ? overlay lists every key. It does not pause the game.

Costs

Buildings

Building	Food	Wood	Size	HP	Pop
Town Center	-	-	3x3	500	+5
House	-	30	2x2	200	+5
Barracks	25	50	2x3	300	-
Farm	-	60	3x3	100	-
Drop Pile	-	50	1x1	100	-

Farms yield 250 food then go fallow. Resow for 60 wood. Repair costs half the original wood cost.

Units

Unit	Food	Wood	HP	DPS	vs Building
Worker	50	-	50	3	2
Soldier	60	20	100	8	5

Resources

Trees yield 10 wood per trip (100 total per tile, 10 trips to fell). Deer yield 10 food per trip (100 total; deer dies on first hunt, stays as a carcass, lightens as drained, removed at 0). Farms yield 10 food per trip (250 total, then fallow; resow 60 wood).

Resource tiles/entities lighten in color as they deplete and disappear when empty.

Deer spawn in herds: one near each TC, the rest scattered with minimum spacing between herd centers. Herd deer stay near their herd center when wandering.

How it works

10 Hz tick loop, decoupled render. Game state is a plain struct — no globals, no heap in the hot path. A* for pathfinding. BFS cluster growth for map generation. Workers keep gathering until you tell them to stop.

Units regenerate 1 HP per 30 ticks (3 seconds), pausing for 5 ticks after taking damage.

Layout

src/
  main.zig, config.zig
  lib/       generic infra (time, fmt, coords, color, pathfinding, spatial, terminal)
  ui/        board, header, footer, color, input
  game/      state, tick, economy, spawning, selection, queries, movement, map, mapgen
  units/     unit, worker, soldier
  buildings/ building, town_center, house, barracks, farm, drop_pile
  resources/ resource, wildlife, deer, tree

Generic algorithms (A/*, entity-by-pos queries, color math, 2D coords) live in lib/ with no game knowledge. Game logic calls them directly. See AGENTS.md for conventions and DESIGN.md for the model. Details: roadmap.md.

Status

Milestone 3 (economy) shipped. Working on buildings (milestone 4).
