How To Create Plugins

This page may be too technical for most readers to understand. Please help improve it to make it understandable to non-experts, without removing the technical details.

Plugins are used to add more Components and ProtoFlux nodes to Resonite by programming them using C#. They are not to be confused with Mods which do not add things into the Data Model.

This page is about writing plugins and should not be confused with the Plugin overview page.

Please see the plugin guidelines before getting started, to familiarize yourself on what is and is not allowed.

Getting started

You will need to know the basics of the C# Programming Language to write plugins.

1. Download Visual Studio Community edition, which allows for easier programming and compilation of plugins. However, you can use your favourite code editor as long as you know how to compile C# into a .dll
   • During installation, ensure to select .NET desktop development which will give you the .NET Framework development tools, which are required to compile a plugin
2. Create a new project using the Class Library template (please ensure it is the C# option). Guidelines follow:
   1. The project name should be the name of your plugin, same with the solution name. It is recommended to not check the box for Place solution and project in the same directory, as you may have multiple parts to your plugin, such as a ProtoFlux Binding generator.
   2. Select the default framework, we'll be manually editing this later.
3. Add references to the following libraries by right clicking on Dependencies, clicking Add Project Reference and then Browse.
   1. FrooxEngine.dll - Found in Resonite/Resonite_Data/Managed/FrooxEngine.dll
   2. Elements.Core.dll - Found in Resonite/Resonite_Data/Managed/Elements.Core.dll
4. Change the referenced framework to net48. To do this:
   1. Double click on your namespace, this will be under your solution
   2. Change the line <TargetFramework>whatever_you_selected_earlier</TargetFramework> to <TargetFramework>net462</TargetFramework> and saving the file
5. Change Your Assembly Info file to tell FrooxEngine what type of plugin you are making.
   1. You will need to add the following line into your Project properties file:
      <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
      inside of a PropertyGroup
   2. Create a folder inside your project called Properties
   3. Create a file called AssemblyInfo.cs which contains the line [assembly: DataModelAssembly(t)], where t is a DataModelAssemblyType.

The framework net462 (step 4) is going to be changed in the future, this will most likely happen with the switch from Unity to Sauce

You're now ready to start writing plugins! Please see the following pages for in depth guides on how to code individual parts of plugins:

• Creating custom Components
• An introduction to creating custom ProtoFlux nodes
• Creating a ProtoFlux Binding

Please note: you are not limited to these guides, you may use any C# syntax.

Object Reference

Object	Description
Components	Used to create custom components
ObjectFunctionNode	A ProtoFlux Node which returns a singular object
ProtoFlux Binding	The binding for a ProtoFlux Node. Without this, a node cannot be loaded into Resonite.
ValueFunctionNode	A ProtoFlux Node which returns a singular value
VoidNode	A ProtoFlux Node which doesn't use return to give an output. Used for nodes with multiple outputs.
