bevy input

Bevy is a popular open-source game engine written in Rust. It provides a high-level API for building interactive applications, including games.

To handle input in Bevy, you can use the Input plugin provided by the Bevy ecosystem. This plugin allows you to capture user input events such as keyboard presses, mouse movements, and button clicks.

Here's a basic example of how to set up input handling in Bevy:

1. Add the bevy_input dependency to your Cargo.toml file:

[dependencies]
bevy = "0.5"
bevy_input = "0.5"

1. Import the necessary modules in your Rust code:

use bevy::prelude::*;
use bevy_input::prelude::*;

1. Set up an event handler system to process input events:

fn input_system(
    keyboard_input: Res<Input<KeyCode>>,
    mouse_input: Res<Input<MouseButton>>,
) {
    // Check for keyboard events
    if keyboard_input.just_pressed(KeyCode::Space) {
        println!("Space key pressed");
    }

    // Check for mouse events
    if mouse_input.just_pressed(MouseButton::Left) {
        println!("Left mouse button pressed");
    }
}

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_startup_system(setup.system())
        .add_system(input_system.system())
        .run();
}

In this example, the input_system function is registered as a system to handle input events. It retrieves the keyboard_input and mouse_input resources using the Res resource type, which allows access to the current state of keyboard and mouse input.

The input_system function checks for specific input events, such as the space key being pressed or the left mouse button being clicked. You can customize this logic to handle different input events based on your application's requirements.

Note that this is just a basic example, and Bevy provides more advanced input handling features, such as input mappings and input event filtering. You can refer to the Bevy documentation for more details on how to use these features.

That's it! You now have a basic understanding of how to handle input in Bevy using the bevy_input plugin.
