NaughtyAttributes

NaughtyAttributes is an extension for the Unity Inspector.

It expands the range of attributes that Unity provides so that you can create powerful inspectors without the need of custom editors or property drawers. It also provides attributes that can be applied to non-serialized fields or functions.

Most of the attributes are implemented using Unity's CustomPropertyDrawer, so they will work in your custom editors. If you want all of the attributes to work in your custom editors, however, you must inherit from NaughtyInspector and use the NaughtyEditorGUI.PropertyField_Layout function instead of EditorGUILayout.PropertyField.

Overview

Drawer Attributes

Provide special draw options to serialized fields. A field can have only one DrawerAttribute. If a field has more than one, only the bottom one will be used.

AnimatorParam

Select an Animator paramater via dropdown interface.

public class NaughtyComponent : MonoBehaviour
{
	public Animator someAnimator;

	[AnimatorParam("someAnimator")]
	public int paramHash;

	[AnimatorParam("someAnimator")]
	public string paramName;
}

Button

A method can be marked as a button. A button appears in the inspector and executes the method if clicked. Works both with instance and static methods.

public class NaughtyComponent : MonoBehaviour
{
	[Button]
	private void MethodOne() { }

	[Button("Button Text")]
	private void MethodTwo() { }
}

CurveRange

Set bounds and modify curve color for AnimationCurves

public class NaughtyComponent : MonoBehaviour
{
	[CurveRange(-1, -1, 1, 1)]
	public AnimationCurve curve;
	
	[CurveRange(EColor.Orange)]
	public AnimationCurve curve1;
	
	[CurveRange(0, 0, 5, 5, EColor.Red)]
	public AnimationCurve curve2;
}

Dropdown

Provides an interface for dropdown value selection.

public class NaughtyComponent : MonoBehaviour
{
	[Dropdown("intValues")]
	public int intValue;

	[Dropdown("StringValues")]
	public string stringValue;

	[Dropdown("GetVectorValues")]
	public Vector3 vectorValue;

	private int[] intValues = new int[] { 1, 2, 3, 4, 5 };

	private List<string> StringValues { get { return new List<string>() { "A", "B", "C", "D", "E" }; } }

	private DropdownList<Vector3> GetVectorValues()
	{
		return new DropdownList<Vector3>()
		{
			{ "Right",   Vector3.right },
			{ "Left",    Vector3.left },
			{ "Up",      Vector3.up },
			{ "Down",    Vector3.down },
			{ "Forward", Vector3.forward },
			{ "Back",    Vector3.back }
		};
	}
}

EnumFlags

Provides dropdown interface for setting enum flags.

public enum Direction
{
	None = 0,
	Right = 1 << 0,
	Left = 1 << 1,
	Up = 1 << 2,
	Down = 1 << 3
}

public class NaughtyComponent : MonoBehaviour
{
	[EnumFlags]
	public Direction flags;
}

Expandable

Make scriptable objects expandable.

public class NaughtyComponent : MonoBehaviour
{
	[Expandable]
	public ScriptableObject scriptableObject;
}

HorizontalLine

public class NaughtyComponent : MonoBehaviour
{
	[HorizontalLine(color: EColor.Red)]
	public int red;

	[HorizontalLine(color: EColor.Green)]
	public int green;

	[HorizontalLine(color: EColor.Blue)]
	public int blue;
}

InfoBox

Used for providing additional information.

public class NaughtyComponent : MonoBehaviour
{
	[InfoBox("This is my int", EInfoBoxType.Normal)]
	public int myInt;

	[InfoBox("This is my float", EInfoBoxType.Warning)]
	public float myFloat;

	[InfoBox("This is my vector", EInfoBoxType.Error)]
	public Vector3 myVector;
}

InputAxis

Select an input axis via dropdown interface.

public class NaughtyComponent : MonoBehaviour
{
	[InputAxis]
	public string inputAxis;
}

MinMaxSlider

A double slider. The min value is saved to the X property, and the max value is saved to the Y property of a Vector2 field.

public class NaughtyComponent : MonoBehaviour
{
	[MinMaxSlider(0.0f, 100.0f)]
	public Vector2 minMaxSlider;
}

ProgressBar

public class NaughtyComponent : MonoBehaviour
{
	[ProgressBar("Health", 300, EColor.Red)]
	public int health = 250;

	[ProgressBar("Mana", 100, EColor.Blue)]
	public int mana = 25;

	[ProgressBar("Stamina", 200, EColor.Green)]
	public int stamina = 150;
}

ReorderableList

Provides array type fields with an interface for easy reordering of elements.

public class NaughtyComponent : MonoBehaviour
{
	[ReorderableList]
	public int[] intArray;

	[ReorderableList]
	public List<float> floatArray;
}

ReadOnly

Makes a field read only.

public class NaughtyComponent : MonoBehaviour
{
	[ReadOnly]
	public Vector3 forwardVector = Vector3.forward;
}

ResizableTextArea

A resizable text area where you can see the whole text. Unlike Unity's Multiline and TextArea attributes where you can see only 3 rows of a given text, and in order to see it or modify it you have to manually scroll down to the desired row.

public class NaughtyComponent : MonoBehaviour
{
	[ResizableTextArea]
	public string resizableTextArea;
}

Scene

Select a scene from the build settings via dropdown interface.

public class NaughtyComponent : MonoBehaviour
{
	[Scene]
	public string bootScene; // scene name

	[Scene]
	public int tutorialScene; // scene index
}

ShowAssetPreview

Shows the texture preview of a given asset (Sprite, Prefab...).

public class NaughtyComponent : MonoBehaviour
{
	[ShowAssetPreview]
	public Sprite sprite;

	[ShowAssetPreview(128, 128)]
	public GameObject prefab;
}

ShowNativeProperty

Shows native C# properties in the inspector. All native properties are displayed at the bottom of the inspector after the non-serialized fields and before the method buttons. It supports only certain types (bool, int, long, float, double, string, Vector2, Vector3, Vector4, Color, Bounds, Rect, UnityEngine.Object).

public class NaughtyComponent : MonoBehaviour
{
	public List<Transform> transforms;

	[ShowNativeProperty]
	public int TransformsCount => transforms.Count;
}

ShowNonSerializedField

Shows non-serialized fields in the inspector. All non-serialized fields are displayed at the bottom of the inspector before the method buttons. Keep in mind that if you change a non-static non-serialized field in the code - the value in the inspector will be updated after you press Play in the editor. There is no such issue with static non-serialized fields because their values are updated at compile time. It supports only certain types (bool, int, long, float, double, string, Vector2, Vector3, Vector4, Color, Bounds, Rect, UnityEngine.Object).

public class NaughtyComponent : MonoBehaviour
{
	[ShowNonSerializedField]
	private int myInt = 10;

	[ShowNonSerializedField]
	private const float PI = 3.14159f;

	[ShowNonSerializedField]
	private static readonly Vector3 CONST_VECTOR = Vector3.one;
}

Tag

Select a tag via dropdown interface.

public class NaughtyComponent : MonoBehaviour
{
	[Tag]
	public string tagField;
}

Meta Attributes

Give the fields meta data. A field can have more than one meta attributes.

BoxGroup

Surrounds grouped fields with a box.

public class NaughtyComponent : MonoBehaviour
{
	[BoxGroup("Integers")]
	public int firstInt;
	[BoxGroup("Integers")]
	public int secondInt;

	[BoxGroup("Floats")]
	public float firstFloat;
	[BoxGroup("Floats")]
	public float secondFloat;
}

Foldout

Makes a foldout group.

public class NaughtyComponent : MonoBehaviour
{
	[Foldout("Integers")]
	public int firstInt;
	[Foldout("Integers")]
	public int secondInt;
}

EnableIf / DisableIf

public class NaughtyComponent : MonoBehaviour
{
	public bool enableMyInt;

	[EnableIf("enableMyInt")]
	public int myInt;

	[EnableIf("Enabled")]
	public float myFloat;

	[EnableIf("NotEnabled")]
	public Vector3 myVector;

	public bool Enabled() { return true; }

	public bool NotEnabled => false;
}

You can have more than one condition.

public class NaughtyComponent : MonoBehaviour
{
	public bool flag0;
	public bool flag1;

	[EnableIf(EConditionOperator.And, "flag0", "flag1")]
	public int enabledIfAll;

	[EnableIf(EConditionOperator.Or, "flag0", "flag1")]
	public int enabledIfAny;
}

ShowIf / HideIf

public class NaughtyComponent : MonoBehaviour
{
	public bool showInt;

	[ShowIf("showInt")]
	public int myInt;

	[ShowIf("AlwaysShow")]
	public float myFloat;

	[ShowIf("NeverShow")]
	public Vector3 myVector;

	public bool AlwaysShow() { return true; }

	public bool NeverShow => false;
}

You can have more than one condition.

public class NaughtyComponent : MonoBehaviour
{
	public bool flag0;
	public bool flag1;

	[ShowIf(EConditionOperator.And, "flag0", "flag1")]
	public int showIfAll;

	[ShowIf(EConditionOperator.Or, "flag0", "flag1")]
	public int showIfAny;
}

Label

Override default field label.

public class NaughtyComponent : MonoBehaviour
{
	[Label("Short Name")]
	public string veryVeryLongName;

	[Label("RGB")]
	public Vector3 vectorXYZ;
}

OnValueChanged

Detects a value change and executes a callback. Keep in mind that the event is detected only when the value is changed from the inspector. If you want a runtime event, you should probably use an event/delegate and subscribe to it.

public class NaughtyComponent : MonoBehaviour
{
	[OnValueChanged("OnValueChangedCallback")]
	public int myInt;

	private void OnValueChangedCallback()
	{
		Debug.Log(myInt);
	}
}

Validator Attributes

Used for validating the fields. A field can have infinite number of validator attributes.

MinValue / MaxValue

Clamps integer and float fields.

public class NaughtyComponent : MonoBehaviour
{
	[MinValue(0), MaxValue(10)]
	public int myInt;

	[MinValue(0.0f)]
	public float myFloat;
}

Required

Used to remind the developer that a given reference type field is required.

public class NaughtyComponent : MonoBehaviour
{
	[Required]
	public Transform myTransform;

	[Required("Custom required text")]
	public GameObject myGameObject;
}

ValidateInput

The most powerful ValidatorAttribute.

public class _NaughtyComponent : MonoBehaviour
{
	[ValidateInput("IsNotNull")]
	public Transform myTransform;

	[ValidateInput("IsGreaterThanZero", "myInteger must be greater than zero")]
	public int myInt;

	private bool IsNotNull(Transform tr)
	{
		return tr != null;
	}

	private bool IsGreaterThanZero(int value)
	{
		return value > 0;
	}
}
