Then this is for you. You can download it as an archive and unpack to a new unity project, or connect it as git submodule. - -xNode is super userfriendly, intuitive and will help you reap the benefits of node graphs in no time. -With a minimal footprint, it is ideal as a base for custom state machines, dialogue systems, decision makers etc. - -

- -### Key features -* Lightweight in runtime -* Very little boilerplate code -* Strong separation of editor and runtime code -* No runtime reflection (unless you need to edit/build node graphs at runtime. In this case, all reflection is cached.) -* Does not rely on any 3rd party plugins -* Custom node inspector code is very similar to regular custom inspector code -* Supported from Unity 5.3 and up - -### Wiki -* [Getting started](https://github.com/Siccity/xNode/wiki/Getting%20Started) - create your very first node node and graph -* [Examples branch](https://github.com/Siccity/xNode/tree/examples) - look at other small projects - -### Installation -
Instructions - -### Installing with Unity Package Manager -***Via Git URL*** -*(Requires Unity version 2018.3.0b7 or above)* - -To install this project as a [Git dependency](https://docs.unity3d.com/Manual/upm-git.html) using the Unity Package Manager, -add the following line to your project's `manifest.json`: - -``` -"com.github.siccity.xnode": "https://github.com/siccity/xNode.git" -``` - -You will need to have Git installed and available in your system's PATH. - -If you are using [Assembly Definitions](https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html) in your project, you will need to add `XNode` and/or `XNodeEditor` as Assembly Definition References. - -***Via OpenUPM*** - -The package is available on the [openupm registry](https://openupm.com). It's recommended to install it via [openupm-cli](https://github.com/openupm/openupm-cli). - -``` -openupm add com.github.siccity.xnode -``` - -### Installing with git -***Via Git Submodule*** - -To add xNode as a [submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) in your existing git project, -run the following git command from your project root: - -``` -git submodule add git@github.com:Siccity/xNode.git Assets/Submodules/xNode -``` - -### Installing 'the old way' -If no source control or package manager is available to you, you can simply copy/paste the source files into your assets folder. - -

-### xNode -Thinking of developing a node-based plugin? Then this is for you. You can download it as an archive and unpack to a new unity project, or connect it as git submodule. - -xNode is super userfriendly, intuitive and will help you reap the benefits of node graphs in no time. -With a minimal footprint, it is ideal as a base for custom state machines, dialogue systems, decision makers etc. - -

- -

- -### Key features -* Lightweight in runtime -* Very little boilerplate code -* Strong separation of editor and runtime code -* No runtime reflection (unless you need to edit/build node graphs at runtime. In this case, all reflection is cached.) -* Does not rely on any 3rd party plugins -* Custom node inspector code is very similar to regular custom inspector code -* Supported from Unity 5.3 and up - -### Wiki -* [Getting started](https://github.com/Siccity/xNode/wiki/Getting%20Started) - create your very first node node and graph -* [Examples branch](https://github.com/Siccity/xNode/tree/examples) - look at other small projects - -### Installing with Unity Package Manager -*(Requires Unity version 2018.3.0b7 or above)* - -To install this project as a [Git dependency](https://docs.unity3d.com/Manual/upm-git.html) using the Unity Package Manager, -add the following line to your project's `manifest.json`: - -``` -"com.github.siccity.xnode": "https://github.com/siccity/xNode.git" -``` - -You will need to have Git installed and available in your system's PATH. - -If you are using [Assembly Definitions](https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html) in your project, you will need to add `XNode` and/or `XNodeEditor` as Assembly Definition References. - -### Node example: -```csharp -// public classes deriving from Node are registered as nodes for use within a graph -public class MathNode : Node { - // Adding [Input] or [Output] is all you need to do to register a field as a valid port on your node - [Input] public float a; - [Input] public float b; - // The value of an output node field is not used for anything, but could be used for caching output results - [Output] public float result; - [Output] public float sum; - - // The value of 'mathType' will be displayed on the node in an editable format, similar to the inspector - public MathType mathType = MathType.Add; - public enum MathType { Add, Subtract, Multiply, Divide} - - // GetValue should be overridden to return a value for any specified output port - public override object GetValue(NodePort port) { - - // Get new a and b values from input connections.

Then this is for you. You can download it as an archive and unpack to a new unity project, or connect it as git submodule. - -xNode is super userfriendly, intuitive and will help you reap the benefits of node graphs in no time. -With a minimal footprint, it is ideal as a base for custom state machines, dialogue systems, decision makers etc. - -

- -### Key features -* Lightweight in runtime -* Very little boilerplate code -* Strong separation of editor and runtime code -* No runtime reflection (unless you need to edit/build node graphs at runtime. In this case, all reflection is cached.) -* Does not rely on any 3rd party plugins -* Custom node inspector code is very similar to regular custom inspector code -* Supported from Unity 5.3 and up - -### Wiki -* [Getting started](https://github.com/Siccity/xNode/wiki/Getting%20Started) - create your very first node node and graph -* [Examples branch](https://github.com/Siccity/xNode/tree/examples) - look at other small projects - -### Installation -
Instructions - -### Installing with Unity Package Manager -***Via Git URL*** -*(Requires Unity version 2018.3.0b7 or above)* - -To install this project as a [Git dependency](https://docs.unity3d.com/Manual/upm-git.html) using the Unity Package Manager, -add the following line to your project's `manifest.json`: - -``` -"com.github.siccity.xnode": "https://github.com/siccity/xNode.git" -``` - -You will need to have Git installed and available in your system's PATH. - -If you are using [Assembly Definitions](https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html) in your project, you will need to add `XNode` and/or `XNodeEditor` as Assembly Definition References. - -***Via OpenUPM*** - -The package is available on the [openupm registry](https://openupm.com). It's recommended to install it via [openupm-cli](https://github.com/openupm/openupm-cli). - -``` -openupm add com.github.siccity.xnode -``` - -### Installing with git -***Via Git Submodule*** - -To add xNode as a [submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules) in your existing git project, -run the following git command from your project root: - -``` -git submodule add git@github.com:Siccity/xNode.git Assets/Submodules/xNode -``` - -### Installing 'the old way' -If no source control or package manager is available to you, you can simply copy/paste the source files into your assets folder. - -
