Units

How a server puts objects on the field and takes them away: champions, minions, neutral monsters, turrets, pets, markers and props. What a unit then does is in Movement, Combat and Spells, and what it is worth in Replication.

Every object is named by a net id, and Objects and identifiers says what removes each kind of object.

Creating

Each kind of object has its own message:

a champion, CreateChampion, which, carrying the client’s own client id, also makes that champion the client’s own; a bot’s champion, the same CreateChampion naming no client, or SpawnBot;
a minion sent out from a side’s barracks, SpawnFromBarracks, and a unit like one, such as a ward, SpawnUnit;
a monster of no side, CreateNeutral; a pet, SpawnPet;
a turret, CreateTurret (The client’s data says how it names one), and a turret of the server’s choosing, SpawnTurret;
an object that follows a unit, CreateFollower, and a change to what it follows, FollowerMaster;
an unseen marker, SpawnMarker, which other messages can name and MarkerMoved moves;
a prop, a thing that stands on the map and is looked at, MapProp, and a change to one, MapPropChanged.

CharacterPreload has a client load a character’s art ahead of need.

In 1.0.0.25–1.0.0.60

A client acts on a CreateChampion or a CreateNeutral whenever it arrives, before CharacterSelected as after.

In 1.0.0.96

A client drops a CreateChampion or a CreateNeutral that arrives before it has loaded the map’s ground grid, which it loads while loading the match.

In 1.0.0.126

A client acts on a CreateChampion or a CreateNeutral whenever it arrives. Once it has reconnected, it drops a SpawnFromBarracks, SpawnUnit or CreateNeutral for an object it already holds.

A client builds a prop from the character its MapProp names, loading that character from its own files when it has not already, and fails soon after the prop comes near what it draws where it cannot load it. A server MUST name in MapProp only characters the client can load.

Changing and removing

TeamChanged moves a unit to another side, and ChampionRemoved takes a champion out of the world. A unit’s death is in Combat.

Bots

A server can tell a client what a bot is thinking (BotDebug), weighing (BotTargets) or doing (BotState). None of them changes what a player sees.

Messages

Each message of this system in this book, with each layout it has across the book’s patches and every note its definition carries. A layout is the message’s body, after the header its channel’s family puts in front (see Messages).

`CreateChampion`

What a server sends to put a champion on the field. The header carries zero or names the object this is about; a client accepts either.

Definition.

In 1.0.0.25–1.0.0.57

Command 6 on events, sent by the server, reliable.

The champion takes the id in champion, not the header’s; a client first removes any object holding that id. For the client’s own seat, name also becomes its own player’s name.

Field	Type	What it is
champion	u32	The name the champion answers to, so later messages can name it.
clientId	u32	The client id of the player the champion belongs to, or 4294967295 where it belongs to none, as a bot’s does. A client takes the champion carrying its own client id as its own.
node	u8	Which network node the object belongs to, in a field of its own.
skillLevel	u8	It has no effect.
side	u8	Nonzero for side 100, zero for side 200.
bot	u8	Nonzero where a bot plays the seat and nobody holds it. A client only keeps it; the shown name is name as sent.
spawnIndex	u8	Where the champion first stands and faces. From 0 to 5, its side’s base position plus the offset the map sets for the side’s head count (players and bots) and this index plus one, facing as the map sets for them. A client works out the head count itself, counting SpawnStart’s bots in it. From 6 up, the base position itself, facing along +X. Movement or sight data replaces it.
skin	i32	Which look it wears.
name	text, 40 bytes	What the seat holding it is called. Written out in full and padded with zero bytes to the width above.
asset	text, 128 bytes	The champion it is: the name the client loads its art and sound under, written and padded as above.

A client ignores the message for a prop it does not know. Whatever the change, it then reads the same bytes again as grouped effects: where the ninth byte of name is not zero, it adds that many effects from the bytes after it, so a name of nine or more characters adds effects besides.
