NaughtyAttributes

Unity 2019.4+ openupm License: MIT

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. The attributes that won't work in your custom editors are the meta attributes and some drawer attributes such as ReorderableList, Button, ShowNonSerializedField and ShowNativeProperty.
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.

NaughtyAttributes is an open-source project that I am developing in my free time. If you like it you can support me by donating.

Overview

Special Attributes

AllowNesting

This attribute must be used in some cases when you want meta attributes to work inside serializable nested structs or classes. You can check in which cases you need to use it here.

public class NaughtyComponent : MonoBehaviour
{
    public MyStruct myStruct;
}

[System.Serializable]
public struct MyStruct
{
    public bool enableFlag;

    [EnableIf("enableFlag")]
    [AllowNesting] // Because it's nested we need to explicitly allow nesting
    public int integer;
}

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;
}

inspector

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() { }
}

inspector

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;
}

inspector

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 }
		};
	}
}

inspector

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;
}

inspector

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

inspector

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;
}

inspector

Select a layer via dropdown interface.

public class NaughtyComponent : MonoBehaviour
{
	[Layer]
	public string layerName;

	[Layer]
	public int layerIndex;
}

inspector

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;
}

inspector

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;
}

inspector

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;
}

inspector

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;
}

inspector

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
}

inspector

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;
}

inspector

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;
}

inspector

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;
}

inspector

	public int firstInt;
	[BoxGroup("Integers")]
	public int secondInt;

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

inspector

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

inspector

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("NeverShow")]
	public Vector3 myVector;

	public bool AlwaysShow() { return true; }

	public bool NeverShow => false;
}

inspector

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;
}

inspector

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);

}

inspector

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")]

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;
	}
}
