Brues 9b5d12c8a1 Document C_Spell.CastAtCursor / C_Item.UseAtCursor 2026-06-03 14:55:00 -05:00
Brues d1bab7a3a4 Add C_Spell.CastAtCursor / C_Item.UseAtCursor
Vanilla 1.12.1 requires a manual click on the AoE reticle to land a
ground-target spell. This pair of functions fires the cast (or
on-use item spell) and immediately commits placement at the
cursor's current world position, matching modern `[@cursor]`
semantics:

  C_Spell.CastAtCursor(spellID)
  C_Item.UseAtCursor(itemInfo)

Chains the engine's own primitives — name-resolver to spellbook
slot, cast dispatcher, then a screen→world raycast via the existing
mouseover machinery and the placement-commit function. Cancels
cleanly when the spell isn't ground-target or the cursor is over
UI / off-screen.

Also extracts the bag-search pattern (used by `UseAtCursor` and
existing by-name action APIs) into `Item::Location::FindByArgInBags`,
alongside the existing `FindByItemID` / `FindByGUID` family.

Brues e657bac266 Suppress fatal-error code 10 so engine accepts ClassicAPI's file overrides
Vanilla 1.12.1 hashes FrameXML.toc + Bindings.xml + each addon's
contents and compares against signature blobs (Interface\FrameXML.sig
+ per-addon stored hash). ClassicAPI's file-read hook diverges those
in memory — Bindings.xml splice and the embedded !!!ClassicAPI addon
— so the engine fires FUN_00401560(10) and terminates with "Your
game interface files are corrupt".

Hook FUN_00401560 and drop calls with code 10. Other codes (login
failures, etc.) pass through unmodified. Stock vanilla binaries
(WoW.exe without a runtime patcher) now load ClassicAPI without
needing TLS-bootloader-style modifications.

Bindings.xml load time, so they appear in the keybind UI alongside
native targeting bindings instead of orphaned at the bottom.

### Bindings (`FOCUSTARGET` / `TARGETFOCUS`)
Two key bindings appear in the keybind UI (`Esc` → Key Bindings)
under the **Targeting Functions** group, between `PETATTACK` and the
Interface section:
| Binding | Lua action | Use |
|---------|------------|-----|
| `FOCUSTARGET` | `FocusUnit("target")` | Pin current target as focus |
| `TARGETFOCUS` | `TargetUnit("focus")` | Switch target to the focus |
No default key — assign one in the keybind UI like any other binding.
The two together give you a quick "set focus → swap to focus" loop
common in PvP / heal-tank-while-killing-add scenarios.
Implementation note: addon-side `Bindings.xml` files always render at
the bottom of the keybind list (orphaned from any `header="..."` they
declare) because the engine's binding registry is linearly indexed by
insertion order and addons load after FrameXML. To land inside the
TARGETING block, the DLL splices the two `<Binding>` entries into the
engine's `Interface\FrameXML\Bindings.xml` at file-read time via a
hook on `FUN_FILE_READ` — see [`src/bindings/Inject.cpp`](../src/bindings/Inject.cpp).

### `C_Item.UseAtCursor(itemInfo)`
Uses `itemInfo` at the player's current cursor world position —
ClassicAPI's `[@cursor]` analog for ground-target on-use items
(Iron Grenade, Bombling, demolition charges, etc.). Returns `true`
when the cursor-placement leg landed (the item fires at terrain);
`false` for items that aren't ground-target (the item still fires
normally with no implicit target), unparseable input, items not in
bags, cursor over UI / off-screen, etc.
`itemInfo` accepts the same shapes as
[`C_Item.UseItemByName`](#c_itemuseitembynameiteminfo--unit) — itemID,
bare `"item:N"`, full chat link, or localized name.
```lua
C_Item.UseAtCursor(4068) -- Iron Grenade at cursor
C_Item.UseAtCursor("Iron Grenade")
```
Implementation chains the existing item-use path
(`Item::Location::FindByArgInBags` + `FUN_ITEM_USE`) with
[`Spell::AtCursor::Resolve`](#c_spellcastatcursorspellid) — same
cursor-resolution helper `C_Spell.CastAtCursor` uses. When the item
fires a non-ground-target spell, the cursor leg no-ops and returns
`false`; the item still uses normally (any implicit target — current
selection, etc. — applies).
Cancels placement automatically when the cursor isn't on terrain —
the item-use packet is never sent, so an off-screen click doesn't
waste the grenade.

### `C_Spell.CastAtCursor(spellID)`
Casts a ground-target spell at the player's current cursor world
position, bypassing the manual click on the AoE reticle the engine
would otherwise require. ClassicAPI's analog of modern's
`/cast [@cursor] Blizzard`. Returns `true` when the cursor-placement
leg landed; `false` for non-ground-target spells (cast still fires
normally on the current target), unknown spellIDs, cursor over UI /
off-screen, etc.

Two-stage internally:
1. Initiates the cast through the same path
[`CastSpellByName`](docs/API.md#numeric-spellids-in-cast-and-castspellbyname)
uses (`FUN_RESOLVE_SPELL_NAME_TO_SLOT` + the engine's cast
dispatcher). If the spell needs a ground target, the engine
enters placement mode and arms the AoE reticle.
2. Refreshes the cursor's screen→world raycast via
`FUN_REFRESH_CURSOR_RAYCAST` (the same internal the engine fires
on every mouse move when placement is active), confirms the
cursor hit terrain (not a UI frame or a unit), and commits
placement via `FUN_COMMIT_PLACEMENT_COORDS` with the resolved
`(x, y, z)`. Cancels placement cleanly via `FUN_STOP_PLACEMENT`
when the cursor isn't on terrain or when the spell wanted a
unit-target rather than ground.
For non-placement spells (regular target casts, self-buffs, etc.)
the cast fires normally; the placement-resolve no-ops since the
engine never set the placement flag, and we return `false`.
The companion item version is
[`C_Item.UseAtCursor`](#c_itemuseatcursoriteminfo) — same chain via
the item-use path for grenades / on-use ground-target items.

// `C_Spell.CastAtCursor(spellID)` — cast a ground-target spell at
// the player's current cursor world position, bypassing the manual
// click on the AoE reticle.
//
// Implementation chains the engine's existing primitives:
//
// 1. Initiate the cast the same way `Script_CastSpellByName` does:
// resolve `spellID` (via our `Spell::CastByID` numeric-name hook)
// to a spellbook slot through `FUN_RESOLVE_SPELL_NAME_TO_SLOT`,
// then dispatch through `FUN_SPELL_CAST_DISPATCH`. For a ground-
// target spell, the engine enters placement mode at this point
// (sets `VAR_SPELL_PLACEMENT_STATE`); for a normal cast, it
// fires immediately.
//
// 2. `Spell::AtCursor::Resolve()` then refreshes the cursor's world
// raycast via `FUN_REFRESH_CURSOR_RAYCAST` and commits the
// placement at the resulting world coords via
// `FUN_COMMIT_PLACEMENT_COORDS`. Self-cancelling when the spell
// isn't ground-target (unit-target placement → cancel) or when
// the cursor isn't on terrain (over UI / off-screen → cancel).
//
// Returns `true` from `Resolve()` when we successfully placed at
// cursor; `false` otherwise (no placement was needed, or cursor was
// invalid). The cast itself proceeds either way — `Resolve()`'s
// return tells the caller whether the cursor-placement leg landed.
