Create Unity Custom Editor - Basics (Part 1)

In this basic lessons we will be going to create our own custom inspectors inside unity.

Before we dive in lets get to know what custom inspectors are

A custom inspector is basically an overridden inspector window which can help artist and designers to interact with the inspector in a more user friendly manner. It also helps to create a neat looking inspector for your scripts attached to gameobjects.

So lets get started with the initial project setup

Steps to follow:

1) Start a fresh project

2) Create a folder name Scripts
This will hold all the scripts(typically monobehaviour) which will be attached to a gameobject in the scene.

3) Create a folder name Editor (Note : it should be the exact same name)
This will hold all the Editor scripts and Unity will automatically detect weather or not the project contains any editor scripts for component scripts.

With this done we have the basic fundamental structure setup for us to create an Inspector Editor.

So lets start by adding a sample icon to our GUI elements. I'll be using this image as a sample You can use any image that you would like to based on your needs. We need to import this image inside Unity. Create a folder named Resources inside the Editor Folder and then import the image inside this folder like this Now select the image and set the texture property to GUI as we will be using this image for our GUI elements. Now in our Code add the following lines We create a Texture2D object to hold our GUI texture that we just imported. We create a GUIContent object that will help us to add text,icon and tooltip field to our GUI elements. In OnInspectorGUI() method we will load our texture from our resources folder.
