source · [−]pub struct EntityCommands<'w, 's, 'a> { /* private fields */ }
Expand description
A list of commands that will be run to modify an entity.
Implementations
sourceimpl<'w, 's, 'a> EntityCommands<'w, 's, 'a>
impl<'w, 's, 'a> EntityCommands<'w, 's, 'a>
sourcepub fn insert_bundle(&mut self, bundle: impl Bundle) -> &mut Self
pub fn insert_bundle(&mut self, bundle: impl Bundle) -> &mut Self
sourcepub fn insert(&mut self, component: impl Component) -> &mut Self
pub fn insert(&mut self, component: impl Component) -> &mut Self
Adds a single Component
to the entity.
Example
Self::insert
can be chained with Commands::spawn
.
fn example_system(mut commands: Commands) {
// Create a new entity with `Component1` and `Component2`
commands.spawn()
.insert(Component1)
.insert(Component2);
// The following statements are equivalent to above one.
commands.spawn().insert_bundle((Component1, Component2));
commands.spawn_bundle((Component1, Component2));
}
sourcepub fn remove_bundle<T>(&mut self) -> &mut Self where
T: Bundle,
pub fn remove_bundle<T>(&mut self) -> &mut Self where
T: Bundle,
Removes a Bundle
of components from the entity.
See EntityMut::remove_bundle
for more
details.
Example
struct Dummy;
fn remove_combat_stats_system(mut commands: Commands, player: Res<PlayerEntity>) {
commands.entity(player.entity).remove_bundle::<CombatBundle>();
}
sourcepub fn remove<T>(&mut self) -> &mut Self where
T: Component,
pub fn remove<T>(&mut self) -> &mut Self where
T: Component,
Removes a single component from the entity.
See EntityMut::remove
for more details.
Example
fn convert_enemy_system(mut commands: Commands, enemy: Res<TargetEnemy>) {
commands.entity(enemy.entity).remove::<Enemy>();
}
sourcepub fn despawn(&mut self)
pub fn despawn(&mut self)
Despawns the entity.
See World::despawn
for more details.
Example
fn remove_character_system(
mut commands: Commands,
character_to_remove: Res<CharacterToRemove>
)
{
commands.entity(character_to_remove.entity).despawn();
}
