League of Legends Replay Observer (player)
====================================

This project provides you a way to **watch your downloaded replays directly in the League of Legend official client** like replay.gg or op.gg feature.

**Please note that is the library only** : you need to connect it with your application *(controller)* and call all available services for each routes. Replays must be downloaded with the https://github.com/EloGank/lol-replay-downloader library *(or the CLI built-in solution)*. See the documentation for more information.  
**If you want a built-in solution of this library**, please see the repository : https://github.com/EloGank/lol-replay-observer-silex.

## Features

* **A fast way to download replays data** (a 40min replay length is downloaded in ~1 minute).
* Avoid a "Bug Slat" on the beginning of the game when the computer has poor performances.
* **Easily extendable**.
* Monolog ready.

## Installation

### Requirements

For now, **this library requires [Redis](http://redis.io/)**.  
Maybe, in the future, this requirement will be optional.

### Composer

In your project, in the folder where the `composer.json` file is located, run :

``` bash
composer require elogank/lol-replay-observer
```

[What is Composer ?](https://getcomposer.org)

### Manually

Clone this repository or [download the full zipped library](https://github.com/EloGank/lol-replay-downloader/archive/master.zip).

## Configuration

Be sure to have a Virtual Host *(Apache, NGINX, or other web servers)* to handle clients requests.  
All your routes must have the prefix `/observer-mode/rest/consumer`.

See usage part below for more informations about routes configuration.

## Usage

See the [usage dedicated documentation](./docs/usage.md) for more information.

## Client configuration

To connect to your client to watch your replays, you have to retrieve some data :

* Your domain name or IP.
* The spectated region *(this is not the same as the game region)*.
* The game id.
* The game encryption key.

All are available in the `metas.json` in the downloaded replay data folder, for example :

``` json
/* metas.json */
{
    "gameKey": {
        "gameId": 1234567890,
        "platformId": "EUW1" /* region */
    },
    "gameServerAddress": "...",
    "port": ...,
    "encryptionKey": "zfBsWycQuDkkDNJhwSzdIYAmsAJu0n2s",
    ...
}
```

Then, run this command *(on Windows, run ![](http://res1.windows.microsoft.com/resbox/en/6.3/main/aa922834-ed43-40f1-8830-d5507badb56c_39.jpg) + R)* by replacing the 4 variables above and the location or your game directory :

```
"C:\Riot Games\RADS\solutions\lol_game_client_sln\releases\0.0.1.113\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator [YOUR_DOMAIN_NAME]:80 [ENCRYPTION_KEY] [GAME_ID] [REGION]"
```

Example with my `metas.json` file data above :

```
"C:\Riot Games\RADS\solutions\lol_game_client_sln\releases\0.0.1.113\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator www.foobar.com:80 zfBsWycQuDkkDNJhwSzdIYAmsAJu0n2s 1234567890 EUW1"
```

**Notes :**

* The `0.0.1.113` folder name can change when the game is updated. Be sure to update it for your users.
* The port (`:80`) is very important here, do not remove it. Of course, you can change it if your website is running on another port.
* You can found some batch files to automatically run the game on lolking.net, op.gg, or other websites that has that feature.

## Important notes

According to the new Riot Terms of Use *(1st October 2014)*, using data from another source of their official API is **not** allowed. So using data by parsing replays decoded files is not allowed.

## Reporting an issue or a feature request

Feel free to open an issue, fork this project or suggest an awesome new feature in the [issue tracker](https://github.com/EloGank/lol-replay-observer/issues).

## Known issues
