Key Actions API

Key actions

A key action is something that runs when a player presses a key combination: a command, your own code, or both. ControlCore detects the keys during play, lets every player rebind them (Keymaps tab, /cc-bind) and lets admins change the server's keys. Read Key binds first for which keys the server can detect.

KeymapsApi keymaps = ControlCoreApi.get().keymaps();

keymaps.register(KeyAction.of("homes", "go-home")          // id homes:go-home
        .displayName("Go home")
        .describedAs("Teleports you to your home.")
        .command("home {player}")                          // run as the player who pressed it
        .defaultKeys(Key.CTRL, Key.NUM_3)                  // held together
        .alternativeKeys(Key.MOUSE_MIDDLE)                 // another combination for the same action
        .onPress(player -> log("home!")));                 // optional: your own code

Building an action

Method	Does
KeyAction.of(modId, action)	the id modId:action; same rules as setting ids
.displayName(…), .describedAs(…)	names in Keymaps and /cc-keys (plain text or Text)
.command("…")	runs the command as the player; {player} and {uuid} are filled in; no leading / needed
.onPress(player -> …)	runs your code with the player's PlayerId
.defaultKeys(…)	inputs held together; leave out for no default
.alternativeKeys(…)	a second combination
.defaultKeys(KeyBinds.parse("ctrl+f | alt+3").value())	the same from text
.keepGameAction()	don't cancel the key's own game action (see below)
.runAsServer()	run the command as the server console
.permission("node")	only players with this full node can see and use it

An action needs command or onPress (or both); otherwise register fails with Keys.NothingToRun.

Inputs

defaultKeys and alternativeKeys take any mix of:

• Key: Key.A … Key.Z, Key.NUM_0 … Key.NUM_9, Key.CTRL, Key.ALT, Key.SHIFT, Key.SPACE, Key.MOUSE_LEFT, Key.MOUSE_RIGHT, Key.MOUSE_MIDDLE, Key.F1 …, Key.TAB, Key.CAPS, …
• GameAction: GameAction.CROUCH, SPRINT, WALK, JUMP, STAND_STILL, INTERACT, ABILITY_1 … ABILITY_4, DODGE, HOTBAR_1 … HOTBAR_9, ATTACK, SECONDARY_ACTION, PICK_BLOCK, SWITCH_GAME_MODE.

Every Key and GameAction is accepted, but only the ones Hytale reports can fire (see which keys work); the others are saved and shown as "not available". Pick defaults that work: Key.CTRL, Key.R or Key.ALT, Key.NUM_3 are good choices; Key.H is not.

How it runs

• Commands go through Hytale's command manager with the player's permissions, on a virtual thread.
• onPress also runs on a virtual thread: hop to the world thread (world.execute(…)) before touching the world.
• A 250 ms cooldown stops repeats.
• When several actions match a press, the one with the most held keys wins (Ctrl+F over F); equal ones all run.
• The pressed key's own game action (ability, interact, attack, game mode switch) is cancelled unless you call .keepGameAction(). Hotbar changes are never cancelled.

Running as the server

keymaps.register(KeyAction.of("admintools", "announce")
        .displayName("Announce restart")
        .command("say Restart in 5 minutes ({player})")
        .runAsServer()                          // console, every permission
        .permission("admintools.announce")      // optional; default ofatech.controlcore.keys.server
        .defaultKeys(Key.CTRL, Key.O));

Only players with the permission see the action and can use it; for others its keys keep their normal behaviour. Every server-run press is logged.

Keys of an action

SettingId id = SettingId.of("homes:go-home");
KeyBinds mine = keymaps.keysFor(id, playerId);    // what fires for this player
KeyBinds server = keymaps.serverKeys(id);         // the server's keys
keymaps.bind(id, playerId, "alt+3");              // a player's own keys
keymaps.resetBind(id, playerId);
keymaps.bindServer(id, "ctrl+h");                 // the server's keys
keymaps.resetServerBind(id);

The mod's defaults apply until an admin changes the server's keys; a player's own keys win over both.

Errors

Code	When
Keys.NothingToRun	no command and no onPress
Keys.InvalidCombo	key text that can't be read
Keys.UnknownAction	no such action, or the player may not use it
Keys.InvalidName	a bad name for an admin bind
Keys.ReservedId	the mod id custom, which is reserved for admins' binds

Storage

The server's keys go to KeyBinds.json; players' keys to players.json.
