Getting Started

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 0.1)]
    [Description("Makes epic stuff happen")]

    class EpicStuff : BlockstormPlugin
    {
        // The rest of the code and magic
    }
}

The Title variable is what defines your plugin. This should be a unique codename or short description such as Pets.

The Author variable is used to show who made the plugin. This should match your OxideMod.org username if releasing.

The Version variable is used to tell if the plugin is outdated or not, and is incremented with each release. Semantic Versioning recommended.

The Description variable helps explain to users what your plugin does, in case the title isn’t enough. Make it good, but not too long!

Timers (Basic)

Timers are great for delaying code, allowing it to be run later.

Single timer

timer.Once(3f, () =>
{
    Puts("Hello world!")
});

Executes the specified function once after the specified delay.

Repeating timer

timer.Repeat(5f, 0, () =>
{
    Puts("Hello world!")
});

Executes the specified function every “delay” seconds.

If “repeats” is specified, the function will only be called “repeats” times.

Next frame timer

NextFrame(() =>
{
    Puts("Hello world!");
});

Executes the specified function at the next frame.

Web Requests

Web requests allow you to send a HTTP GET or POST to a specified URL.

The request will return true if the web request was sent, false if not. The callback is called with 2 parameters - an integer HTTP response code and a string response.

Basic Get method

using Oxide.Core.Libraries.Covalence;

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 1.0)]
    [Description("This example illustrates how to use a GET WebRequest")]

    class EpicStuff : CovalencePlugin
    {
        [Command("get")]
        void GetRequest(IPlayer player, string command, string[] args)
        {
            webrequest.EnqueueGet("http://www.google.com/search?q=oxide", (code, response) => GetCallback(code, response, player), this);
        }

        void GetCallback(int code, string response, IPlayer player)
        {
            if (response == null || code != 200)
            {
                Puts($"Error: {code} - Couldn't get an answer from Google for {player.Name}");
                return;
            }

            Puts($"Google answered for {player.Name}: {response}");
        }
    }
}

This uses the raw connection to a web page as you would on your browser.

Basic POST method

using Oxide.Core.Libraries.Covalence;

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 1.0)]
    [Description("This example illustrates how to use a POST WebRequest")]

    class EpicStuff : CovalencePlugin
    {
        [Command("post")]
        void PostRequest(IPlayer player, string command, string[] args)
        {
            webrequest.EnqueuePost("http://www.google.com/search?q=oxide", "param1=value1&param2=value2", (code, response) => PostCallback(code, response, player), this);
        }

        void PostCallback(int code, string response, IPlayer player)
        {
            if (response == null || code != 200)
            {
                Puts($"Error: {code} - Couldn't get an answer from Google for {player.Name}");
                return;
            }
            Puts("Google answered for " + player.Name + ": " + response);
        }
    }
}

Advanced GET method

using Oxide.Core.Libraries.Covalence;

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 1.0)]
    [Description("This example illustrates how to use a GET WebRequest")]

    class EpicStuff : CovalencePlugin
    {
        [Command("get")]
        void GetRequest(IPlayer player, string command, string[] args)
        {
            // Set a custom timeout (in milliseconds)
            var timeout = 200f;

            // Set some custom request headers (eg. for HTTP Basic Auth)
            var headers = new Dictionary<string, string> { { "header", "value" } };

            webrequest.EnqueueGet("http://www.google.com/search?q=oxide", (code, response) => GetCallback(code, response, player), this, headers, timeout);
        }

        void GetCallback(int code, string response, IPlayer player)
        {
            if (response == null || code != 200)
            {
                Puts($"Error: {code} - Couldn't get an answer from Google for {player.Name}");
                return;
            }

            Puts($"Google answered for {player.Name}: {response}");
        }
    }
}

Advanced POST method

using Oxide.Core.Libraries.Covalence;

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 1.0)]
    [Description("This example illustrates how to use a POST WebRequest")]

    class EpicStuff : CovalencePlugin
    {
        [Command("post")]
        void PostRequest(IPlayer player, string command, string[] args)
        {
            // Set a timeout (in milliseconds)
            var timeout = 200f;

            // Set some custom request headers (eg. for HTTP Basic Auth)
            var headers = new Dictionary<string, string> { { "header", "value" } };

            webrequest.EnqueuePost("http://www.google.com/search?q=oxide", "param1=value1&param2=value2", (code, response) => PostCallback(code, response, player), this, headers, timeout);
        }

        void PostCallback(int code, string response, IPlayer player)
        {
            if (response == null || code != 200)
            {
                Puts($"Error: {code} - Couldn't get an answer from Google for {player.Name}");
                return;
            }
            Puts("Google answered for " + player.Name + ": " + response);
        }
    }
}

Plugin Calling

Oxide allows you to expose methods in your plugin and make them available to other plugins. This allows you to access objects or properties from other plugins without having to replicate functionality yourself.

Exposing a plugin’s method

namespace Oxide.Plugins
{
    [Info("EpicStuff", "Unknown", 0.1)]
    [Description("Makes epic stuff happen")]

    class EpicStuff : CovalencePlugin
    {
        // Plugin methods can be a simple bool that is returned
        bool GetReturn()
        {
            return true;
        }

        // Plugin methods can take parameters and return simple types
        string TakeParam(string param, int secondParam)
        {
            if (param == "first parameter") return param;
            else return "First parameter didn't match!";
        }

        // To return complex types, they should first be converted
        // into builtin types (e.g. JSON.net types like JObject, JArray, etc. or builtin
        // collections like System.Collections.Generic.Dictionary)
        JObject ReturnObject()
        {
            var myObject = new JObject();
            myObject["key"] = "value";
            myObject["array"] = new JArray();
            return myObject;
        }

        // Plugin methods don't have to return something
        void SendMessage()
        {
            Puts("You just called the 'SendMessage' method!");
        }
    }
}

Exposing a plugin’s method allows other plugins to call that method.

For example, you could write a plugin that does some player management, then allow other plugins to “query” it to get a list of players who have certain privileges set in the original plugin.

Calling a plugin’s method

namespace Oxide.Plugins
{
    [Info("SecondEpicStuff", "Unknown", 0.1)]
    [Description("Makes more epic stuff happen")]

    class SecondEpicStuff : CovalencePlugin
    {
        // First, add a reference to the plugin you are trying to call
        // The name of this field needs to be the exact name of the desired plugin
        // eg. We are referencing the example plugin above which is called 'EpicStuff'
        [PluginReference] Plugin EpicStuff;

        // It's a good idea to check if the plugin you're trying to call
        // has been loaded by oxide (otherwise you can't call the method)
        void OnServerInitialized()
        {
            // Note: Trying to do this check in the plugin Init() method may
            // fail, as the plugin load order may be different each time
            if (EpicStuff == null)
            {
                PrintWarning("Plugin 'EpicStuff' was not found!");
            }
        }

        void CallPlugin()
        {
            // Plugin methods return objects, so cast the API call to the type
            // you're expecting
            var getTypedReturn = (bool)EpicStuff?.Call("GetReturn");

            // Send parameters through as variables after the method name
            var takeParam = (string)EpicStuff?.Call("TakeParam", "param1", 1024);

            // Use JSON.net to process the returned object
            var returnedObject = EpicStuff?.Call("ReturnObject");

            // Call a plugin to do some work without returning anything
            EpicStuff?.Call("SendMessage");
        }
    }
}

Calling a plugin’s method allows you to access results from another plugin.
