D2NG

Building the project

This project builds with .NET 8 and can be built by running dotnet build on the command line from the root of the Solution.

Functionality

Initially based on https://github.com/dkuwahara/D2NG, but now with a lot more features.

• Bots: Mephisto, Travincal, Pindle, Cows, Cs, Baal (and it's easy to add new bots)
• Pathing module using https://github.com/jcageman/d2mapapi
• Gambling, pickit, muling

Configuring

Commandline parameters: config="D:\projects\diablo2bot\config.json" muleconfig="D:\projects\diablo2bot\muleconfig.json" The above config.json should look as follows:

{
    "bot": {
        "realm": "xx.xxx.xxx.xxx",
        "keyOwner": "test",
        "gameNamePrefix": "test",
        "gamePassword": "x",
        "gameDescriptions": ["trade","offer soj"],
        "difficulty" : "hell",
        "channelToJoin": "",
        "gamefolder": "C:\\Diablo II1.09D",
        "botType" : "mephisto",
	"logFile": "meph1log.txt",
	"mephisto" : {"username": "test", "password": "testpass", "character" : "testcharacter"}
	},
    "externalMessaging" : {
        "telegramApiKey": "5231-xxerew",
        "telegramChatId": 1234
    },
    "map" : {
       "apiUrl" : "http://localhost:8080"
    }
}

The realm ip address can be retrieved with a tool like https://www.wireshark.org/. Start filtering on tcp port 6112 (in wireshark the filter would be tcp.port == 6112 as filter). You should receive packets and as soon as you enter the login screen. The source or destination address of the packets is the ip address you need to fill in for the bot.realm parameter. Source/Destination can be your own ip or the ip of the diablo 2 server, so double check the ip you enter is not your own by using something like https://www.whatismyip.com/

The above muleconfig.json should look as follows:

{
	"mule": {
		"accounts": [
			{
				"username": "test1",
				"password": "testpass",
				"excludedCharacters" : ["testchar1"],
				"matchesAny": [
					{
						"matchesAll" : [{"itemName" : "ring", "qualityType" : "unique" }]
					},
					{
						"matchesAll" : [{"itemName" : "perfectSkull"}]
					}
				]
			},
			{
				"username": "test2",
				"password": "testpass",
				"excludedCharacters" : ["testchar2", "testchar3"],
				"matchesAny": [
					{
						"matchesAll" : [{"notFilter" : true, "itemName" : "ring", "qualityType" : "unique" }, {"notFilter" : true, "classificationType" : "gem"}]
					}
				]
			},
			{
				"username": "test2",
				"password": "testpass",
				"includedCharacters" : ["testchar3"],
				"matchesAny": [
					{
						"matchesAll" : [{"itemName" : "perfectDiamond"}]
					},
					{
						"matchesAll" : [{"itemName" : "perfectAmethyst"}]
					},
					{
						"matchesAll" : [{"itemName" : "perfectEmerald"}]
					},
					{
						"matchesAll" : [{"itemName" : "perfectRuby"}]
					},
					{
						"matchesAll" : [{"itemName" : "perfectDiamond"}]
					}
				]
			}
		]
	}
}

See https://core.telegram.org/bots for configuration of the telegram bot

To be able to run the bot you also need to configure the MapClient from https://github.com/jcageman/d2mapapi If you run this locally this runs on localhost port 8080 (which is also the default in the above config)

Future ideas

1. Implement pickit using .nip files (used in many other bots)
2. Improve chicken/pot behavior (currently runs in a separate thread, probably better to use task scheduling)
3. Auto leveling / rushing bots

Analyzing Packets

Besides the ConsoleBot there is another CLI project called PacketSniffer, which you can use to analyse packets send by the bot, but also by any started diablo client connected to a realm. The PacketSniffer currently only monitors packets send by the game server (i.e. the packets send when you are in a game). This is 100% safe to use in all cases and undetectable. You could use this is you are not sure if your server is using the same version of 1.09d or if you simply want to analyze the game server yourself.
