## Pull Requests
Try to keep your pull requests relevant, neat, and manageable. If you are adding multiple features, try splitting them into separate commits.
Try to keep your pull requests relevant, neat, and manageable. If you are adding multiple features, split them into separate PRs.
* Avoid including irellevant whitespace or formatting changes.
* Comment your code.
* Spell check your code / comments
* Use consistent formatting

If your feature aims to cover something not related to editing nodes, it generally won't be accepted. If in doubt, ask on the Discord channel.
## Coding conventions
Skim through the code and you'll get the hang of it quickly.
Using consistent formatting is key to having a clean git history. Skim through the code and you'll get the hang of it quickly.
* Methods, Types and properties PascalCase
* Variables camelCase
* Public methods XML commented
* Public methods XML commented. Params described if not obvious
* Explicit usage of brackets when doing multiple math operations on the same line
## Formatting
I use VSCode with the C# FixFormat extension and the following setting overrides:
```json
"csharpfixformat.style.spaces.beforeParenthesis": false,
"csharpfixformat.style.indent.regionIgnored": true
```
* Open braces on same line as condition
* 4 spaces for indentation.

* 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:
