Restricting a player

What a server can stop a player from doing, one player at a time. The rules for everyone are in Server rules.

Member	Effect
`setCuffed(true)`	hands behind the back; they can only walk and look, and only the upper body takes the pose
`noclipAllowed = false`	no flying with `NoClip`; true by default and again on rejoining, so set it in `playerJoin` (Free camera)
`frozen = true`	held in place; see below
`putInPillory(name?)`, `releaseFromPillory()`	the pillory
`setPace(mode)`	forbids running or sprinting
`stopFight(opponent)`	ends a fight
`makePeace()`	ends every fight they are in; `opponents` lists who they fought in the last 15 s
`setInteraction(name, allowed)`	the game's interactions for this player; see Server rules; `interactionAllowed(name)` reads one
`trespassAllowed`, `combatMarker`	read: whether they may be in private areas now, and whether they see the combat marker
`setLockable(false)` (client)	combat targeting on this machine cannot pick that player, as for someone lying wounded

frozen works like Npc.frozen. Their game lets through only looking around and menus, and a modified game that moves the body anyway is put back within a second. A script's teleport moves the spot where they are held. It ends when they leave the server.

Locking on: a player struck in melee by another player while locked on nobody locks on the striker, as the game locks on an NPC that attacks. stopFight and makePeace drop the lock again.

Making peace: makePeace() ends every fight the player is in, with each of opponents, the players they swung at or who swung at them in the last 15 seconds. Offer it on a key the player holds:

// client
const { Keybinds } = kcds.ui;
Keybinds.add('make_peace', { label: 'Make peace', key: 'h' });
let since = 0;
Keybinds.on('make_peace', (id, state) => {
  if (state === 'down') {
    since = Date.now();
  } else if (Date.now() - since >= 1000) {
    kcds.core.Events.toServer('peace');
  }
});

kcds.core.Events.fromClient('peace', (player) => {
  player.makePeace();
});
