Installation

Supported Clients

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

The currently supported version of the client: 2.7.4.84161

Server Deploying

Prepare Database

Manual

1. Install PostgreSQL 9.5.25.
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.

Or using docker

1. Install docker
2. Run docker-compose up from root folder (here).

Compile and run

1. Install .NET 7 SDK and runtime (just runtime, not asp.net or desktop)
2. Go to the repo directory and compile the project using this command:

dotnet publish ./src/DiIiS-NA/Blizzless.csproj --configuration Release --output ./publish

3. Skip this stage for local game Copy the config.mods.json file to the folder, and modify however you want. A file will be generated automatically from the config.ini for now.
4. Update your config.ini file on the published folder with your network's IP records (BindIP and PublicIP)
5. Go to the publish folder, launch Blizzless executable, wait until server start - it creates a hierarchy.
6. Create user account(s) using console: !account add Login Password Tag

• Example:
• !account add username@ YourPassword YourBattleTag
• Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag
• !account add username@ YourPassword YourBattleTag owner
• Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag with rank owner

Example:

!account add username@ YourPassword YourBattleTag

Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag

!account add username@ YourPassword YourBattleTag owner

Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag with rank owner

Example:

!account add username@ YourPassword YourBattleTag

Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag

!account add username@ YourPassword YourBattleTag owner

Creates an account with Login username@, password YourPassword and BattleTag YourBattleTag with rank owner

Prepare Client

Do this for each client connecting to the server.

1. Get supported client D3 (2.7.4).

2. Install certificate 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 (Windows - %WinDir%\System32\drivers\etc\hosts, Linux - /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

   // 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!

Exit portal: fix the teleport at the end of the GR so it appears and works correctly.
Resource consumption: make sure the GR Stone and gold are properly consumed when energizing the rift.
Death time penalty: implement the correct penalty (+5 seconds per death after the 3rd inside the GR).
Mob removal: clear all enemies after a GR is finished.
Next-level portal display: ensure the portal to the next GR level only appears when appropriate.
Level display bug: fix the issue that shows only GR level 13 Torment 2.
GR pillars validation: review and validate the behavior of GR pillars.

2️⃣ Items & Crafting
