helix / FunctionContext

Class: FunctionContext

Defined in: core/frontend/context/index.ts:13

The author-facing context. It is just the shared plumbing (ContextBase): emit/call/version/child functions. EVERY ctx.<command>() method - sugar (say, tellraw, score ops, if, give, …) and vanilla (weather, effect, …) alike - is a FunctionContext.prototype augmentation that lives WITH its command in src/core/commands/<cmd>.ts (interface + prototype). Importing src/core/commands (done by the frontend barrel) installs them all, so each command is fully self-contained and the public API stays ctx.<command>(...).

atEntity()

atEntity(selector, build, align?): void

Defined in: core/commands/at_entity.ts:68

Run the commands emitted in build anchored at selector's position with one execute at <selector> [align <axes>] run …. A single command inlines into the run clause; multiple commands commit to one child function and the wrapper runs … run function <child> - so the selector is evaluated once, not re-scanned per command (important when it's an expensive @a[…,nbt={…}] filter). Pass align (e.g. "xyz") to snap the anchor to the block grid first - needed when block ops (fill/place) ride an entity at a fractional position.

createChildFunction()

createChildFunction(suffix): FunctionNode

Defined in: core/frontend/context/base.ts:45

A uniquely-named nested function for control-flow bodies (if/elif/else, at). Public so the if augmentation in commands/if.ts can build child bodies.

Generated helpers live under the shared PRIVATE_ROOT folder so they sort away from authored functions (a leading-underscore name sorted them to the top of the list, in the way). The name nests by parent path - tick → zzz/tick/if_0 → zzz/tick/if_0/at_0 - stripping the root from the parent so the prefix doesn't compound into noise on each nesting level.

Parameters

suffix

string

Returns

FunctionNode

Inherited from

ContextBase.createChildFunction

whenEntity()

whenEntity(selector, build, mode?): void

Defined in: core/commands/entity_guard.ts:70

Run each command emitted in build only when an entity matches selector

• one execute (if|unless) entity <selector> run <command> line per emitted command (mode defaults to "if"). The body runs against a child context, so this is the API-level way to wrap a block of commands in an entity guard without touching the IR. Pair with Selector.volume(...) for "every player inside a box" triggers.

Parameters

selector

Selector

build

(ctx) => void

mode?

"if" | "unless"

Returns

void

---

whenItems()

whenItems(target, slot, item, build, mode?): void

Defined in: core/commands/items_guard.ts:67

Run each command emitted in build only when target's slot holds an item matching item - one execute (if|unless) items entity <target> <slot> <item_predicate> run <command> line per emitted command (mode defaults to "if"). item is matched as an item predicate built from the same ItemValue you'd give, so the check sees the exact components (name/lore/model) the item was granted with. Use this to act on a precise slot when an equipment/holding predicate (worn slots only) can't reach it.

Parameters

target

Selector

slot

string

item

ItemValue

build

(ctx) => void

mode?

"if" | "unless"

Returns

void

---

whenPlayerNear()

whenPlayerNear(pos, radius, build, unlessSelector?): void

Defined in: core/commands/near_guard.ts:92

Run each command emitted in build only when a player is within radius blocks of pos. Pass unlessSelector to additionally gate on that entity being absent (a re-arm guard, so a held-down trigger doesn't refire).

By default this is a single presence check - execute positioned <pos> if entity @a[distance=..radius] … run <command> - so the body runs once no matter how many players are in range.

Opt into a per-player handle by declaring a second build parameter: the body then runs as @a[distance=..radius], once per nearby player, with the passed Selector (@s) bound to that player. Use this only when the body needs the player (e.g. ctx.tellraw(player, …)); the extra as-fan-out is why it isn't the default.

Parameters

pos

PosValue

radius

number

build

(ctx, player) => void

unlessSelector?

void
