Spells

Casting, levelling spells, cooldowns, and the missiles casts send out.

Casting

A client asks to cast from one of its champion’s slots with CastSpell, at a point or at a unit. A server answers with SpellCastAnswer, which says the unit is casting and carries the whole casting: the spell, its level, its target, its timings and the missile it will send. A client shows the cast from that answer; CastSpell alone shows nothing. A server then sets how long until the slot is ready with SpellCooldown, and, for a spell with uses, how many are left with SpellCharges. A client reports a cooldown it sets by itself with CooldownSet.

Which slots a client lets its player cast from at all is a value of the champion’s that replication carries.

A client casts nothing for a casting record whose length disagrees with its count of targets.

The casting record names the spell by the hash of its name, and a client casts nothing for a spell it has not loaded.

A spell held down before it is let go charges where the cast answer leaves its flags clear. While it charges, a client sends SpellCharge with the cursor’s position, and once more as the charge ends.

A server ends a spell’s aiming on a client with CancelTargeting, shows and takes away a spell’s targeter on a client’s own champion with SpellTargeterShown and SpellTargeterHidden, and sets which spells a unit casts by itself with Autocast.

Levelling

A client asks to put a point into a spell with UpgradeSpell. A server answers with SpellUpgraded, and a client shows the new level; SpellLevel sets a level outright. The spell points a champion has to spend are what LevelUp carries. A server can set how far each spell can be raised, and at which champion levels, with SpellRankLimits.

A client spends the point as it sends UpgradeSpell. LevelUp states the champion’s level and its points.

What a slot holds

SpellInSlot puts a spell in a slot. SpellSlotChanged changes one thing about a spell already there: how it is aimed, its name, its ranges, its icon, or the units it is cast from. SpellTargetingChanged, SpellNameChanged, SpellRangeChanged, SpellIconChanged and SpellOffsetTargetChanged each change one of these alone, and SpellSlotChangedForOwner changes a slot as SpellSlotChanged does, for the owner’s client alone. SpellToggled turns a spell on or off, SpellNumbers fills in the numbers a client shows beside a unit’s spells, and SpellCostChanged changes what a spell costs. A server can also draw rings around its player’s cursor with CursorRings.

A marker has no slots. A server MUST NOT send SpellInSlot naming a marker: a client fails on it, whatever the slot.

Missiles

A missile is named by its own id. MissileState says where one is and what it is doing, with the casting that sent it; MissileLaunched says the missile a swing or a cast prepared has left the unit. A server changes what a missile flies at with MissileRetarget and how fast with MissileSpeed, says what it struck with MissileHits, and is rid of it with DestroyMissile. A missile that bounces from unit to unit does so with BounceMissile, and a server can name in advance the units a chain missile will strike with ChainTargets. MissileCourse sets where a missile starts and how fast it flies, and restarts its flight. A client reports where a missile that flies straight is, and where it is going, with MissileReport, which a server MAY ignore.

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).

`CastSpell`

What a client sends to cast something from a slot, at a point or at a unit. The header names the sender’s champion.

`ChainTargets`

What a server sends to name the units a chain missile will strike in turn. The header names the missile.

Definition.

In 1.0.0.130–1.0.0.137

Carried on events, sent by the server, reliable, under these commands:

Builds	Command
1.0.0.130–1.0.0.131	111
1.0.0.132–1.0.0.137	112

Where the client already holds the missile, the missile takes the list; otherwise the list waits for the caster’s next chain missile.

Field	Type	What it is
count	i32	How many of the slots are used, 0 to 32.
caster	u32	The unit casting the missile.
targets	32 × u32	Always 32 slots; those past count have no effect.

In 1.0.0.138–1.0.0.143

Command 114 on events, sent by the server, reliable.

A client drops the message unless the match is running, it holds caster, and caster has a cast in progress. It keeps the list for the caster’s next chain missile, even where it already holds the missile.

Field	Type	What it is
count	i32	How many of the slots are used, 0 to 32.
caster	u32	The unit casting the missile.
targets	32 × u32	Always 32 slots; those past count have no effect.

`MissileCourse`

What a server sends to set where a missile starts from and how fast it travels, which restarts its flight. The header names the missile.

Definition.

In 1.0.0.132–1.0.0.134

Command 66 on events, sent by the server, reliable.

Field	Type	What it is
driver	u8	How the missile is driven; only 1, homing, exists.
kind	u32	Must be 1, or the block is ignored.
target	u32	The unit homed on.
height	f32	Added to the target’s height.
targetX	f32	The point homed on, which the client refreshes from the target while it exists.
targetY	f32	Its height.
targetZ	f32	Its other ground axis.
motionA	f32	A value of the homing motion; what it does is not recorded.
motionB	f32	Another.
motionC	f32	Another.
motionD	f32	Another.
last	u32	Kept with the homing; what it does is not recorded.
