🔄 Turn Order

34 rollover steps130 player steps164 total

Everything below is the game's own order of operations, extracted from the doTurn() functions in the shipped source. When two things seem to happen "at the same time" — a build finishing and a tech completing, a character dying and an event firing — this page tells you which one the engine actually resolves first. Step order is source order; every step carries its file:line.

How a round is structured

The engine advances turns from Game.testTurn() (Game.cs:3257): once every currently-active player has ended their turn (shouldIncrementTurn, Game.cs:3359), nextTeamTurn() (Game.cs:4238) moves play along. A full round looks like this:

Players play, team by team (or all at once in simultaneous multiplayer). When a player's turn ends, their 0-HP units die and stunned units drop to a normal cooldown (processEndTurn, Player.cs:16906).
The tribe turn. After the last team, tribal and unaffiliated characters take their character turns (Game.cs:4381), the AI moves tribal units, every tribal unit runs its unit turn, and tribal cities act (playCurrentTurn, Game.cs:3269–3314).
The turn rollover. When the tribe turn finishes, incrementTurn() bumps the turn counter and runs Game.doTurn() — the first band below — then checks game over (Game.cs:3175–3188, Game.cs:4247–4250). So the world updates after the tribes act and before the first player's new turn.
Each player's turn begins. As a player becomes current, Player.doTurn() — the second band below — runs before they get control (Game.cs:4316).

Multiplayer nuances visible in the source: in simultaneous mode all players' turn-start processing runs back-to-back in player-index order in one pass (Game.cs:4310–4322); in play-by-cloud / server games the save uploads and "your turn" notifications go out right after a human's turn-start processing (Game.cs:4324–4353); hotseat autosaves and switches the active player (Game.cs:4354–4360).

Common ordering questions

Does a build or a tech finish first?: City production applies and builds finish at step P18.7; Science is banked right after at step P19 — where it goes straight into the current tech and can complete it — with any remainder flushed at step P24. So builds finish first, techs immediately after, both before your units and characters are processed.
When are ambitions checked?: At the very end of turn-start processing: progress recomputes at step P49, expired ambitions fail at step P51, and new offers roll at step P54 — all after that turn's event rolls (step P42). Whatever you finished last turn is already counted.
Do characters die before or after events fire?: Death rolls happen inside each character's yearly tick during step P34 — before the player's story-event rolls at step P42. The leader deliberately goes last (step P34), and missions resolve after all character turns (step P46) so mid-event state changes can't invalidate them.
When do my units heal?: During your turn-start unit processing (step P29): healing applies at sub-step P29.23, and the idle bonus only counts if the unit took no action last turn. Units heal before you move anything.
When do tribes and raiders act?: Tribal units and cities act in their own turn slot after all players (see "How a round is structured"). On top of that, camps roll raids during the rollover at step R4.8, and each of your cities rolls for distant raids at step P18.3.
When does the market move?: Prices drift once per round during the rollover (step R3), before any player's turn. Forced debt sales (step P26) therefore trade at the already-adjusted price.

What this page does not pin down

Which event fires. The order of the event rolls is exact, but event selection inside doEventTrigger is weighted and subject-filtered — there is no fixed priority between individual events.
AI decision details. AI.doDecisions, doAutomatedCityBuilds and the AI diplomacy passes delegate into PlayerAI.cs; their internal ordering isn't part of the turn skeleton shown here.
Relative order between players. Within one rollover, per-player loops run in player-index order (host's setup order); in simultaneous multiplayer that ordering is internal and not visible in-game.

Source: Game.cs doTurn() / testTurn() / nextTeamTurn(), Player.cs doTurn() / processTurn(), plus the nested Tile, Tribe, City, Unit and Character turn functions — extracted by scripts/build_turn_order.py into src/data/turn_order.json. R = rollover step, P = player step.
