Bevyengine 消失时出现恐慌

Question

我使用 bevy 0.6 和 rapierphysicals_2d 0.12.0 清理现场后我感到恐慌。我有以下两个函数：：

fn cleanup_player(mut commands: Commands, player_data: Res<PlayerData>, query: Query<Entity>) {
  commands
      .entity(player_data.player_entity)
      .despawn_recursive();
  commands
      .entity(player_data.camera_entity)
      .despawn_recursive();
}

fn cleanup(mut commands: Commands, query: Query<Entity>) {
  for entity in query.iter() {
      commands.entity(entity).despawn_recursive();
  }
}

如您所见，它们只是消失之前创建的实体。但如果我使用其中任何一个，都会引起恐慌。

我实际上试图在从 InGame 更改为 MainMenu 时调用它们（通过按 ESC）

impl Plugin for PugPlugin {
    fn build(&self, app: &mut App) {
        app.add_plugin(RapierPhysicsPlugin::<NoUserData>::default())
        .add_system(camera_follow_player.label("Camera system"))
            .add_system_set(
                SystemSet::on_enter(crate::AppState::InGame)
                    .with_system(sprite_spawn)
                    .with_system(spawn_floor),
            )
            .add_system_set(
                SystemSet::on_update(crate::AppState::InGame)
                    .with_system(check_delete)
                    .with_system(myphysics::player_jumps.label("Player Jumps System"))
                    .with_system(myphysics::jump_reset.label("Jump Reset System"))
                    .with_system(myphysics::player_movement.label("Player Movement System"))
                    .with_system(death_by_height.label("Death system"))
                    ,
            )
             .add_system_set(SystemSet::on_exit(AppState::InGame).with_system(cleanup).with_system(cleanup_player))
            ;
    }
}

您可以在最后看到系统设置。所以我想从 InGame Set 切换到主菜单，但它不起作用。

即使没有任何到 MainMenu 或其他的转换，只是清理功能也无法在场景内工作。所以我什至不能从我的游戏中删除任何实体。

所以这是我的 rapier2d 物理插件的问题！

cargo update -p bevy_rapier2d

从 0.12.0 更新到 0.12.1 解决了我的问题
