Unity Editor Toolbox

Introduction

Improve usability and clarity of key features in Unity Editor for better workflow!

This Toolbox not only extends functionalities, it does so with the user in mind. Written to be as flexible and optimized as possible. Now you and other programming professionals will be able to create a readable and useful component editor simply by using attributes. You’ll get fast and clear access to data from GameObjects placed in the Scene. Lastly, you’ll gain more control over the Project window. Go ahead, customize those folder icons.

It's worth to mention that prepared drawers are based on the custom, layout-based system. Additionally, I’m leaving you some useful scripts, classes, and functions that facilitate Editor extensions development.

Learn all the details about the main features below.

System Requirements

Unity 2018.x or newer

Dependencies

EditorCoroutines

Installation

Install Editor Toolbox package:
- 1 way: Find Unity Package Manager (Window/Package Manager) and add package using this git URL:
```
 https://github.com/arimger/Unity-Editor-Toolbox.git#upm
```
- 2 way: Copy and paste Editor Toolbox directory into your project (Assets/...)
Open Edit/Project Settings/Editor Toolbox window
If settings file is not found, press "Refresh" button or create new one
Manage settings in your way
- Enable/disable Hierarchy overlay, choose allowed information
- Enable/disable Project icons or/and assign own directories
- Enable/disable Toolbox drawers or/and assign custom drawers

Settings

The most important file, it allows the user to manage all available features. Can be accessed from the Project Settings window (Edit/Project Settings.../Editor Toolbox) or directly inside the Project window. Make sure to have one valid settings file per project.

Available features are divided into three groups:

Hierarchy
Project
Inspector/Drawers

Each module is described in its respective section.

Toolbox Drawers

Drawers are based on classes inherited from the ToolboxDrawer class and associated ToolboxAttribute. With this powerful custom system you are able to create really flexible drawers. You can use them without limitations (they work with sub-classes and as array children). Every ToolboxDrawer is layout-based. For proper work they need at least one settings file located in your project. You can find predefined one here - Editor Toolbox/EditorSettings.asset.

Examples 'How to' create custom ToolboxDrawers you can find HERE.

Editor Toolbox/Scripts/Attributes/ToolboxAttributes
Editor Toolbox/Editor/Drawers/ToolboxDrawers

ToolboxDecoratorAttributes

Display/create something before and after property in the desired order (using Order property).
In fact ToolboxDecoratorDrawers are like extended version of built-in DecoratorDrawers. Unfortunately, standard decorators won't always work with ToolboxDrawers so try to use this replacement instead.

[BeginGroup("Group1")]
public int var1;
public int var2;
public int var3;
[EndGroup]
public int var4;

[BeginHorizontal]
public int var1;
public int var2;
[EndHorizontal]
public int var3;

[BeginIndent]
public int var1;
public int var2;
public int var3;
[EndIndent]
public int var4;

[SpaceArea(spaceBefore = 10.0f, spaceAfter = 5.0f, Order = 1)]
public int var1;

[Label("My Custom Header", skinStyle: SkinStyle.Box, Alignment = TextAnchor.MiddleCenter)]
public int var1;

[EditorButton("MyMethodName", "<b>My</b> Custom Label", activityType: ButtonActivityType.OnPlayMode)]
public int var1;

[Highlight(0, 1, 0)]
public int var1;

[Help("Help information", UnityMessageType.Warning, Order = -1)]
public int var1;

[ImageArea("https://img.itch.zone/aW1nLzE5Mjc3NzUucG5n/original/Viawjm.png", 150.0f)]
public int var1;

ToolboxConditionDrawers

Enable/disable or show/hide properties using custom conditions. You can use them together with any other type of drawer. Every ToolboxConditionDrawer supports boolean, int, string and enum types and works even with array/list properties.

public string stringValue = "sho";
[ShowIf(nameof(stringValue), "show")] //or HideIfAttribute
public int var1;

public KeyCode enumValue = KeyCode.A;
[EnableIf(nameof(enumValue), KeyCode.A)] //or DisableIfAttribute
public int var1;

[DisableInPlayMode]
public int var1;

[Disable, ReorderableList]
public int[] vars1 = new [] { 1, 2, 3, 4 };

InLineEditorAttribute

This attribute gives a great possibility to extend all reference-related (UnityEngine.Object) fields. Using it you are able to 'inline' Editors for: components, ScriptableObjects, Materials, Renderers, MeshFilters, Textures, AudioClips, etc.

[InLineEditor]
public Transform var1;

[InLineEditor]
public AudioClip var1;

[InLineEditor(true, true)]
public Material var1;

ScrollableItemsAttribute

It's a perfect solution to inspect large arrays/lists and optimize displaying them within the Inspector window.

[ScrollableItems(defaultMinIndex: 0, defaultMaxIndex: 5)]
public GameObject[] largeArray = new GameObject[19];

Reorderable List

Custom implementation of standard ReorderableList (UnityEditorInternal). Usable as an attribute in serialized fields or a single object in custom Editors.

Editor Toolbox/Editor/Internal/ReorderableList.cs

var list = new ReorderableList(SerializedProperty property, string elementLabel, bool draggable, bool hasHeader, bool fixedSize);

[ReorderableList(ListStyle.Lined, "Item")]
public List<int> linedStyleList;

[ReorderableList(ListStyle.Round)]
public List<string> standardStyleList;

[ReorderableList(ListStyle.Boxed, fixedSize: true)]
public GameObject[] boxedStyleList = new GameObject[4];

Editor Extensions

Hierarchy

Enable and customize the presented hierarchy overlay in the ToolboxEditorSettings. Basically it provides more data about particular GameObjects directly within the Hierarchy window. Additionally, you can create special 'Header' objects using the '#h' prefix or Create menu: GameObject/Editor Toolbox/Hierarchy Header (by default created object will have EditorOnly tag).

Each row can contain:

Scripts information
Layer
Tag
Toggle to enable/disable GameObject
Icon

Editor Toolbox/Editor/ToolboxEditorHierarchy.cs

Project

Set custom folder icons in the ToolboxEditorSettings.

Properties that can be edited include:

XY position and scale of the large icon
XY position and scale of the small icon
Path to directory or name (depends on picked item type)
Optional tooltip
Large icon
Small icon

Editor Toolbox/Editor/ToolboxEditorProject.cs

Toolbar

Editor Toolbox/Editor/ToolboxEditorToolbar.cs

Check Examples for more details.

Examples/Editor/SampleToolbar.cs

using Toolbox.Editor;

[UnityEditor.InitializeOnLoad]
public static class MyEditorUtility
{
	static MyEditorUtility()
	{
		ToolboxEditorToolbar.OnToolbarGui += OnToolbarGui;
	}
	
	private static void OnToolbarGui()
	{
		GUILayout.FlexibleSpace();
		if (GUILayout.Button("1", Style.commandLeftStyle))
		{
			Debug.Log("1");
		}
		if (GUILayout.Button("2", Style.commandMidStyle))
		{
			Debug.Log("2");
		}
		if (GUILayout.Button("3", Style.commandMidStyle))
		{
			Debug.Log("3");
		}
		if (GUILayout.Button("4", Style.commandMidStyle))
		{
			Debug.Log("4");
		}
		if (GUILayout.Button("5", Style.commandRightStyle))
		{
			Debug.Log("5");
		}
	}
}

Utilities

Copy and paste all components from/to particular GameObject.

Editor Extras

I decieded to move additional editors and tools to Gist.
