Bevy Despawn With

此crate实现了对Commands的扩展trait，即DespawnAllCommandsExt，该trait包含两个方法despawn_all和despawn_all_recursive，用于销毁多个实体

fn despawn_system(
    mut commands: Commands,
) {
    commands.despawn_all::<(With<People>, With<Shoes>, Without<Laces>)>();
}

用法

将依赖项添加到项目的Cargo.toml文件中的[dependencies]部分

bevy_despawn_with = "0.15.0"

然后销毁一些东西

use bevy_despawn_with::DespawnAllCommandsExt;

fn despawn_system(mut commands: Commands) {
    // Despawn all entities with a MenuUiMarker component
    commands.despawn_all::<With<MenuUiMarker>>();

    // Despawn all entities without a SomeOtherMarker component, 
    // and despawn those entities descendants.
    commands.despawn_all_recursive::<Without<SomeOtherMarker>>();

    // Despawn all entities with a MenuUiMarker component, or with a changed GlobalTransform.
    commands.despawn_all::<Or<(With<MenUiMarker>, Changed<GlobalTransform>)>>();
}

示例

cargo run --example despawn_with
cargo run --example despawn_without
