Ongedraaid – How to Create a Plugin

A guide on creating your first plugin.

You’ll probably need Visual Studio 2019 Community Edition. Alongside that, this guide doesn’t tell you how to first set up your project. Here is a video on how to do that (you can also instead watch the tutorial series made by that creator):

Creating Your First Plugin

Creating plugins for Unturned requires a general knowledge of C#. If you currently do not have any knowledge behind C#, please check out Microsoft’s introduction to the language.

All plugins normally begin with class that inherits the `RocketPlugin` class. Below is an example of how to properly implement this:

using Rocket.API;
using Rocket.Core.Plugins;

namespace ExamplePlugin
{
public class ExamplePlugin : RocketPlugin
{

}
}

Notice how the `ExamplePlugin` class is public? This is so we can make it accessible to RocketMod.

Verder gaan, you can now override the `Load` and `Unload` methods contained within the `RocketPlugin` class to log the loading and unloading of your plugin:

using Rocket.API;
using Rocket.Core.Plugins;
using Rocket.Unturned;
using Rocket.Unturned.Chat;
using Rocket.Unturned.Player;
using Rocket.Core.Logging;

namespace ExamplePlugin
{
public class ExamplePlugin : RocketPlugin
{
protected override void Load()
{
Logger.Log("Example plugin loaded!");
}

protected override void Unload()
{
Logger.Log("Example plugin unloaded!");
}
}
}

The plugin will now log in the server console that the plugin has been loaded and unloaded.

You can also subscribe and unsubscribe to events when the plugin loads and unloads:

using Rocket.API;
using Rocket.Core.Plugins;
using Rocket.Unturned;
using Rocket.Core.Logging;

namespace ExamplePlugin
{
public class ExamplePlugin : RocketPlugin
{
protected override void Load()
{
Logger.Log("Example plugin loaded!");

U.Events.OnPlayerConnected += OnPlayerConnected;
}

protected override void Unload()
{
Logger.Log("Example plugin unloaded!");

U.Events.OnPlayerConnected -= OnPlayerConnected;
}

public void OnPlayerConnected(UnturnedPlayer player)
{
}
}
}

The plugin now subscribes and unsubscribes to the `U.Events.OnPlayerConnected`event on load and unload.

You can also now greet the player when they connect to the server:

using Rocket.API;
using Rocket.Core.Plugins;
using Rocket.Unturned;
using Rocket.Core.Logging;

namespace ExamplePlugin
{
public class ExamplePlugin : RocketPlugin
{
protected override void Load()
{
Logger.Log("Example plugin loaded!");

U.Events.OnPlayerConnected += OnPlayerConnected;
}

protected override void Unload()
{
Logger.Log("Example plugin unloaded!");

U.Events.OnPlayerConnected -= OnPlayerConnected;
}

public void OnPlayerConnected(UnturnedPlayer player)
{
// Do something when a player connects
UnturnedChat.Say(speler, "Welcome to the server!");
}
}
}

To conclude, This plugin will log a message when it is loaded and unloaded, and greet players when they connect to the server. Natuurlijk, you can customize the plugin to do whatever you want it to do.
