# King of the Hill — Round Signals & Game End

This step wires up announcements for each new round and explains how the game ends automatically when the final round completes.

## How Signal Volumes Work

Signal volumes have special tags (`SignalRoundStart`, `SignalPhaseTick`, `SignalPhaseStart`, etc.) that the runtime writes to at the right moment. When the tag value changes, Hytale fires the volume's `TAG_ADDED` trigger, which runs the attached effects.

Every signal volume must also have `MinigameId` set so the runtime knows which game's signals to respond to.

## Round 2 Announcement

When Round 2 begins, fire a message to all players announcing the new hill location.

**Volume type:** Any (Tag Added trigger is conventional for signal volumes — the volume is never physically entered, it is fired by the runtime)

**Tags:**

| Tag | Value |
|---|---|
| `MinigameId` | `King_Of_The_Hill` |
| `MapId` | `Hillside` |
| `SignalRoundStart` | `2` |

**Effects:**

| Effect | Fields |
|---|---|
| `SendMinigameMessage` | `MinigameId = King_Of_The_Hill`, `MessageKey = round_2_start`, `Target = ALL` |

> `MessageKey` references a translation key in your server's language files. If you do not have a dedicated translations setup, you can skip `SendMinigameMessage` for now — the HUD already shows the updated round number automatically.

## Round 3 Announcement

Same structure, fires when Round 3 begins.

**Tags:**

| Tag | Value |
|---|---|
| `MinigameId` | `King_Of_The_Hill` |
| `MapId` | `Hillside` |
| `SignalRoundStart` | `3` |

**Effects:**

| Effect | Fields |
|---|---|
| `SendMinigameMessage` | `MinigameId = King_Of_The_Hill`, `MessageKey = round_3_start`, `Target = ALL` |

---

## How the Game Ends Automatically

When the Round 3 timer expires, the runtime calls `end()` automatically (because `TotalRounds = 3` and neither `OvertimeEnabled` nor `SuddenDeathEnabled` are set). No extra timer volume is needed.

The end sequence fires in this order:

1. `SignalPhaseStart=ENDING` fires — use this for a scoreboard display, player freeze, or end announcement.
2. HUDs are removed, inventories restored, rewards distributed.
3. `on_game_end` event fires (with `reason = "rounds_complete"`).
4. Runtime is removed from the active list.
5. `SignalPhaseStart=RESETTING` fires — use this to restore blocks, re-enable the queue pad, etc.
6. `on_arena_reset` event fires.

You do not need a `StartTimer`/`SignalOnTimerExpire` pair to end the game.

## ENDING Phase Volume (Optional)

To show a final message or freeze players briefly at game end, respond to `SignalPhaseStart=ENDING`:

**Tags:**

| Tag | Value |
|---|---|
| `MinigameId` | `King_Of_The_Hill` |
| `MapId` | `Hillside` |
| `SignalPhaseStart` | `ENDING` |

**Example effects:**

| Effect | Fields |
|---|---|
| `SendMinigameMessage` | `MinigameId = King_Of_The_Hill`, `MessageKey = game_over`, `Target = ALL` |

---

## Round 1 Announcement (Optional)

Round 1 begins immediately when the game goes ACTIVE (there is no `SignalRoundStart=1` in the current round implementation for the initial round). If you want a Round 1 announcement, fire it from the `SignalPhaseStart=ACTIVE` volume set up in step 03:

**Tags:**

| Tag | Value |
|---|---|
| `MinigameId` | `King_Of_The_Hill` |
| `MapId` | `Hillside` |
| `SignalPhaseStart` | `ACTIVE` |

**Effects:**

| Effect | Fields |
|---|---|
| `SendMinigameMessage` | `MinigameId = King_Of_The_Hill`, `MessageKey = round_1_start`, `Target = ALL` |
