Rust Bevy Query Option

The Rust Bevy game engine does not have a built-in query option. However, you can use the bevy_ecs crate to implement a query system in your Rust Bevy project. The bevy_ecs crate provides the Query struct, which allows you to query entities based on specific component criteria.

To use the Query struct, you need to define a system that takes a Query parameter. Here's an example of how you can implement a simple query system in Rust Bevy:

use bevy::prelude::*;

struct Position {
    x: f32,
    y: f32,

struct Velocity {
    dx: f32,
    dy: f32,

fn move_system(mut query: Query<(&mut Position, &Velocity)>) {
    for (mut position, velocity) in query.iter_mut() {
        position.x += velocity.dx;
        position.y += velocity.dy;

fn main() {

In this example, we define two components: Position and Velocity. The move_system function queries entities that have both Position and Velocity components and updates their positions based on the velocity.

Please note that this is a simplified example, and you can customize the query criteria and system logic based on your specific requirements.
