# Extending the editor

Since Airship uses Unity, most of the custom editor features will work as-is. Some examples of features you might may want to add to your project:

* [Adding editor menus](https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MenuItem.html)

Airship also has our own analogous versions of Unity features such as

* [Adding custom property inspectors for `AirshipBehaviour`s](/editor-extensions/custom-inspectors-c.md)

### Before you begin

If you are planning to write C# scripts for the editor, it's recommended you turn *off* the TypeScript compiler *while* you write C# editor code.

This will change the TypeScript menu to add options to start/stop the compiler. This can be utilized to stop the compiler recompiling each time you make a C# change.

### Airship Editor C# API

Airship has the following user editor APIs you can use:

* \
  `AirshipSerializedProperty`  and `AirshipSerializedObject` for handling Airship Behaviour property serialization
* `AirshipCustomEditors` for querying the registered custom inspectors for AirshipBehaviours
  * See [AirshipBehaviour inspectors](/editor-extensions/custom-inspectors-c.md) for how to add custom editors
* `AirshipType` which is the Airship version of `Type` for TypeScript-based types.
  * Types can be queried using `AirshipType.GetType(name)`&#x20;
* `AirshipEditorGUI` - for drawing editor properties for `AirshipSerializedProperty` instances using IMGUI.
* `AirshipGUI` for general Airship GUI state
* `TypescriptService` for general TypeScript APIs
* `TypescriptProjectsService.Project` for querying the project settings
* `TypescriptCompilationService` for querying the compiler state
