# Installation

## Supported Clients

Each version of the client includes changes to structures, opcodes and attributes.

The currently supported version of the client: **2.7.3.82785**

## Server Deploying

1. Install [PostgreSQL 9.5.25](https://www.enterprisedb.com/downloads/postgres-postgresql-downloads).
2. Create databases in PostgreSQL: `diiis` and `worlds`.
3. Change you account and password in `database.Account.config` and `database.Worlds.conifg`.
4. Restore `worlds.backup` to `worlds` database.
5. Compile by [VS 2019/2022](https://visualstudio.microsoft.com/).
6. [Skip this stage for local game] Copy the [config.ini](configs/config.ini) file to the server folder (It overwrites the default settings):
	- Update the parameter entries with your IP record on the network: `BindIP` and `PublicIP`.
7. Launch wait until server start, it creates a hierarchy.
8. Create user account(s) using console: `!account add Login Password Tag`

## Prepare Client

Do this for each client connecting to the server.

1. Get [supported client](#supported-clients) Diablo 3.

2. Install certificate [bnetserver.p12](src/DiIiS-NA/bnetserver.p12), password - `123` (the game verifies the CA root certificates).

3. Setting up redirects client to your server:

	**Method #1 - Hosts**

	  Add redirects to the `hosts` file (`%WinDir%\System32\drivers\etc\hosts`):  
	  `127.0.0.1 us.actual.battle.net`  
	  `127.0.0.1 eu.actual.battle.net`

	  !After the modification the official Battle.Net application will not be able to connect to the server!

	  **Method #2 - Modify main executable file**

	  ```c
	  // Find null-terminated string enum and rewrite with HexEditor to your IP server.
	  eu.actual.battle.net/
	  us.actual.battle.net/
	  cn.actual.battle.net/
	  kr.actual.battle.net/
	  ```

4. Launch client (`x64` or `x86`) with arguments `"Diablo III64.exe" -launch`

5. Login to the game using your credentials.

6. [Skip this stage for local game] After that, when creating a game (in client), indicate the creation of a public game. Other players, when connecting, must also indicate a public game, and at the start they will connect to you.

7. You're in the game world!

## Using Docker
