Only use the beta versions when you use the beta server from https://altv.mp/#/downloads

Download from https://altv.mp/#/downloads, you can select stable or beta and windows or linux.

• Add csharp-module to server.cfg

...
modules: ["csharp-module"]
...

or with node-module

...
modules: [
"csharp-module"
"node-module"
]
...

resource.cfg:

type: "csharp",
main: "AltV.Net.Example.dll"

(empty index.mjs) resource.cfg:

type: "js",
main: index.mjs
client-main: "client.mjs",
client-files: [ "client.mjs" ]

client-files specify files downloaded by the client

client-files: [ 
"file1.mjs"
"file2.mjs"
index.html
image.png
]

"" around files are optional

wildcards are also supported

client-files: [ 
"client/*"
]

server.cfg:

resources: [
"login-screen"
]

client file imports are based on ecmascript2015 imports https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Statements/import but require full path import like import * as auth from 'client/auth.mjs'; (relative from resource folder)

• https://www.nuget.org/packages/AltV.Net
• optional async module https://www.nuget.org/packages/AltV.Net.Async

.NET Core SDK can be found here. You have to install the sdk, the runtime isn't needed.

• Go to "File -> New -> Project..." now the Project Wizard should appear.
• In the left Column select "Installed -> Visual C# -> .NET Core".
• Now select "Class Library (.NET Core)" and choose "Name", "Location" and the "Solution name".
• To setup the correct NuGet Packages open the Manager under "Tools -> NuGet Package Manager -> Manage NuGet Packages for Solution..."
• Select Browse and search for AltV.Net and install the packages "AltV.Net", ("AltV.Net.Async" when you need async thread save api access)
• Now go to "Project -> {Your Project Name} Properties... -> Build", here you can select the Output path where the dll should be saved.

To get the Resource running on the server, you have to create a "resource.cfg" file. Copy the resource.cfg, AltV.Net.dll and all other dependencied with your resource dll file to altv-server/resources/{YourResourceName}/.

MyResource.cs

using System;

namespace My.Package
{
    internal class MyResource : Resource
    {
        public override void OnStart()
        {
            Alt.OnServerEvent += (name, args) => { Alt.Log(name + " " + args.Length); };
            Alt.Emit("test");

            Console.WriteLine("Started");
        }

        public override void OnStop()
        {
            Console.WriteLine("Stopped");
        }
    }
}

Alt.OnPlayerConnect += OnPlayerConnect;
Alt.OnPlayerDisconnect += OnPlayerDisconnect; (play disconnected)
Alt.OnPlayerRemove += OnPlayerRemove; (player entity removed from memory)
Alt.OnVehicleRemove += OnVehicleRemove;
Alt.OnConsoleCommand += (name, args) => { };
Alt.OnPlayerEvent += (player, name, args) => { Alt.Log("event:" + name); }; (generic event handler for all event names)
...(and a lot more)

Alt.Emit is used to illustrate event triggering from server -> server, in most use cases the client would trigger the events.

null, bool, int, uint, long, ulong, double, string, object, float

All types above as an array, eg. int [], string[], ....

Furthermore Dictionaries with string-Type as Key, eg. Dictionary<string, object>

But also all interfaces of the AltV API or extend these, eg. IEntity, IVehicle, IBlip, ICheckpoint, MyVehicle ...

Alt.On("test", args => { Alt.Log("args=" + args[0]); });

Alt.Emit("test", "bla");

Alt.On<string>("test", str => { Alt.Log("str=" + str); });

Alt.Emit("test", "bla");

Alt.On("test", delegate(string str){ Alt.Log("str=" + str); });

Alt.Emit("test", "bla");

Alt.On<string>("test", bla);
void bla(string str) {
    Alt.Log("str=" + str);
}
Alt.Emit("test", "bla");

The first Generics (in our example below int and string) are the Types for the parameters, the last generic (bool) is the return-type.

Note: Return types are optional at events

Alt.On<int, string, bool>("test", (number, str) => {
    Alt.Log("str=" + str + " - " + number);
	return true;
});

You can send objects when the objects are implementing IWritable.

e.g.

List<WritableObject> objects;
player.Emit("objects", objects);

WritableObject.cs:

public class WritableObject : IWritable
{
    private readonly string test;

    public WritableObject()
    {
        test = "123";
    }

    public void OnWrite(IMValueWriter writer)
    {
        writer.BeginObject();
        writer.Name("test");
        writer.Value(test);
        writer.EndObject();
    }
}

Needed when you want to improve performance by not using entity.GetData(..), entity.SetData(...) but entity.MyData... instead

SampleResource.cs:

public class SampleResource : Resource
...
public override IEntityFactory<IVehicle> GetVehicleFactory()
{
    return new MyVehicleFactory();
}
...(also supports player, blip, checkpoint, ....)

MyVehicleFactory.cs:

namespace My.Package
{
    public class MyVehicleFactory : IEntityFactory<IVehicle>
    {
        public IVehicle Create(IntPtr vehiclePointer, ushort id)
        {
            return new MyVehicle(vehiclePointer, id);
        }
    }
}

MyVehicle.cs

namespace AltV.Net.Example
{
    public class MyVehicle : Vehicle, IMyVehicle
    {
        public int MyData { get; set; }

        public MyVehicle(IntPtr nativePointer, ushort id) : base(nativePointer, id)
        {
            MyData = 6;
        }
    }
}

All entity apis can be found in the interfaces of the entities IPlayer IVehicle IBlip ICheckpoint
