Azalea is a framework for creating Minecraft bots.
Internally, it's just a wrapper over [`azalea_client`], adding useful
functions for making bots. Because of this, lots of the documentation will
refer to `azalea_client`. You can just replace these with `azalea` in your
code, since everything from azalea_client is re-exported in azalea.
# Installation
First, install Rust nightly with `rustup install nightly` and `rustup
default nightly`.
Then, add one of the following lines to your Cargo.toml:
Latest bleeding-edge version:
`azalea = { git="https://github.com/mat-1/azalea" }`\
Latest "stable" release:
`azalea = "0.5.0"`
## Optimization
For faster compile times, make a `.cargo/config.toml` file in your project
and copy
[this file](https://github.com/mat-1/azalea/blob/main/.cargo/config.toml)
into it. You may have to install the LLD linker.
For faster performance in debug mode, add the following code to your
Cargo.toml:
```toml
[profile.dev]
opt-level = 1
[profile.dev.package."*"]
opt-level = 3
```
# Examples
```rust,no_run
//! A bot that logs chat messages sent in the server to the console.
use azalea::prelude::*;
use parking_lot::Mutex;
use std::sync::Arc;
#[tokio::main]
async fn main() {
let account = Account::offline("bot");
// or Account::microsoft("example@example.com").await.unwrap();
loop {
let e = azalea::ClientBuilder::new()
.set_handler(handle)
.start(account, "localhost")
.await;
eprintln!("{:?}", e);
}
}
#[derive(Default, Clone, Component)]
pub struct State {}
async fn handle(bot: Client, event: Event, state: State) -> anyhow::Result<()> {
match event {
Event::Chat(m) => {
println!("{}", m.message().to_ansi());
}
_ => {}
}
Ok(())
}
```
# Plugins
Azalea uses [Bevy ECS](https://docs.rs/bevy_ecs) internally to store information about the world and clients. Bevy plugins are more powerful than async handler functions, but more difficult to use. See [pathfinder](azalea/src/pathfinder/mod.rs) as an example of how to make a plugin. You can then enable a plugin by adding `.add_plugin(ExamplePlugin)` in your client/swarm builder.
Also note that just because something is an entity in the ECS doesn't mean that it's a Minecraft entity. You can filter for that by having `With<MinecraftEntityId>` as a filter.
See the [Bevy Cheatbook](https://bevy-cheatbook.github.io/programming/ecs-intro.html) to learn more about Bevy ECS (and the ECS paradigm in general).
