# D2-Stampede

Dota 2 replay parser written in Rust.

### Quick Start

```rust
use d2_stampede::prelude::*;
use d2_stampede::proto::*;

// Create struct that implements Default trait
#[derive(Default)]
struct Chat;

// Mark impl block with observer attribute
#[observer]
impl Chat {
    #[on_message] // Use on_message attribute to mark protobuf message handler
    fn handle_chat_msg(
        &mut self,
        ctx: &Context,
        chat_msg: CDotaUserMsgChatMessage, // Use any protobuf message as an argument
    ) -> ObserverResult {
        if let Ok(pr) = ctx.entities().get_by_class_name("CDOTA_PlayerResource") {
            let name: String = property!(
                pr,
                "m_vecPlayerData.{:04}.m_iszPlayerName",
                chat_msg.source_player_id()
            );
            println!("{}: {}", name, chat_msg.message_text());
        }
        Ok(())
    }
}

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Read replay file
    let replay = unsafe { memmap2::Mmap::map(&std::fs::File::open("replay.dem")?)? };

    // Create parser 
    let mut parser = Parser::new(&replay)?;

    // Register observers
    parser.register_observer::<Chat>();

    // Parse replay from start to end
    parser.run_to_end()?;

    // Or parse only parts of replay
    parser.jump_to_tick(10000)?;
    parser.run_to_tick(11000)?;

    Ok(())
}

```
