Struct CastContext 

pub struct CastContext {
    pub caster: Entity,
    pub targets: Vec<Entity>,
    pub origin: Option<Vec3>,
}

Context passed to each Rune when a spell is executed.

Contains the caster and an arbitrary number of targets, supporting single-target, multi-target, and self-cast spells uniformly.

origin carries a pre-computed world position. It is primarily used by post-death (OnDespawn) runes that fire after the caster entity is gone, so rune logic can fall back to this position instead of querying the (now-despawned) entity’s Transform.

Fields

caster: Entity

The entity that is casting the spell.

targets: Vec<Entity>

Every entity targeted by this cast. May be empty for self-cast spells.

origin: Option<Vec3>

Optional world position override. Populated for OnDespawn enchantments so runes can locate the origin without a live entity.

Implementations

impl CastContext

pub fn new(caster: Entity) -> Self

Creates a self-cast context with no targets.

pub fn with_targets(self, targets: impl IntoIterator<Item = Entity>) -> Self

Builder-style: attach targets to the context.

pub fn with_target(self, target: Entity) -> Self

pub fn with_origin(self, origin: Vec3) -> Self

Set the origin position override (used by OnDespawn runes).
