How to change the names of a Vector 3 that is set in the inspector

Question

Is there a way to change the names of the X, Y, and Z in a vector 3 that is set in the inspector? alt text

Answer 1

If you don't want to have an additionnal structure, (especially if you manage Vector2, Vector3, ...) here is a custom property drawer I made:

VectorLabelsAttribute.cs in your Scripts folder

 using UnityEngine;

 public class VectorLabelsAttribute : PropertyAttribute
 {
     public readonly string[] Labels;
 
     public VectorLabelsAttribute( params string[] labels )
     {
         Labels = labels;
     }
 }

VectorLabelsAttributeDrawer.cs in an Editor folder

 using UnityEditor;
 using UnityEngine;
 
 [CustomPropertyDrawer( typeof( VectorLabelsAttribute ) )]
 public class VectorLabelsAttributeDrawer : PropertyDrawer
 {
     private static readonly GUIContent[] defaultLabels = new GUIContent[]{ new GUIContent( "X" ), new GUIContent( "Y" ), new GUIContent( "Z" ), new GUIContent( "W" ) };
 
     private const int twoLinesThreshold = 375;
 
     public override float GetPropertyHeight( SerializedProperty property, GUIContent label )
     {
         int factor = Screen.width < twoLinesThreshold ? 2 : 1;
         return factor * base.GetPropertyHeight( property, label );
     }
 
     // Draw the property inside the given rect
     public override void OnGUI( Rect position, SerializedProperty property, GUIContent label )
     {
         VectorLabelsAttribute vectorLabels = (VectorLabelsAttribute)attribute;
 
         if ( property.propertyType == SerializedPropertyType.Vector2Int )
         {
             int[] array = new int[] { property.vector2IntValue.x, property.vector2IntValue.y };
             array = DrawFields( position, array, ObjectNames.NicifyVariableName( property.name ), EditorGUI.IntField, vectorLabels );
             property.vector2IntValue = new Vector2Int( array[0], array[1] );
         }
         else if ( property.propertyType == SerializedPropertyType.Vector3Int )
         {
             int[] array = new int[] { property.vector3IntValue.x, property.vector3IntValue.y, property.vector3IntValue.z };
             array = DrawFields( position, array, ObjectNames.NicifyVariableName( property.name ), EditorGUI.IntField, vectorLabels );
             property.vector3IntValue = new Vector3Int( array[0], array[1], array[2] );
         }
         else if ( property.propertyType == SerializedPropertyType.Vector2 )
         {
             float[] array = new float[] { property.vector2Value.x, property.vector2Value.y };
             array = DrawFields( position, array, ObjectNames.NicifyVariableName( property.name ), EditorGUI.FloatField, vectorLabels );
             property.vector2Value = new Vector2( array[0], array[1] );
         }
         else if ( property.propertyType == SerializedPropertyType.Vector3 )
         {
             float[] array = new float[] { property.vector3Value.x, property.vector3Value.y, property.vector3Value.z };
             array = DrawFields( position, array, ObjectNames.NicifyVariableName( property.name ), EditorGUI.FloatField, vectorLabels );
             property.vector3Value = new Vector3( array[0], array[1], array[2] );
         }
         else if ( property.propertyType == SerializedPropertyType.Vector4 )
         {
             float[] array = new float[] { property.vector4Value.x, property.vector4Value.y, property.vector4Value.z, property.vector4Value.w };
             array = DrawFields( position, array, ObjectNames.NicifyVariableName( property.name ), EditorGUI.FloatField, vectorLabels );
             property.vector4Value = new Vector4( array[0], array[1], array[2] );
         }
     }
 
     private T[] DrawFields<T>( Rect rect, T[] vector, string mainLabel, System.Func<Rect, GUIContent, T, T> fieldDrawer, VectorLabelsAttribute vectorLabels )
     {
         T[] result = vector;
 
         bool twoLinesLayout = Screen.width < twoLinesThreshold;
 
         // Get the rect of the main label
         Rect mainLabelRect = rect;
         mainLabelRect.width = EditorGUIUtility.labelWidth;
         if ( twoLinesLayout )
             mainLabelRect.height *= 0.5f;
 
         // Get the size of each field rect
         Rect fieldRect = rect;
         if ( twoLinesLayout )
         {
             fieldRect.height *= 0.5f;
             fieldRect.y += fieldRect.height;
             fieldRect.width = rect.width / vector.Length;
         }
         else
         {
             fieldRect.x += mainLabelRect.width;
             fieldRect.width = ( rect.width - mainLabelRect.width ) / vector.Length;
         }
 
         EditorGUI.LabelField( mainLabelRect, mainLabel );
 
         for ( int i = 0 ; i < vector.Length ; i++ )
         {
             GUIContent label            = vectorLabels.Labels.Length > i ? new GUIContent( vectorLabels.Labels[i] ) : defaultLabels[i] ;
             Vector2 labelSize           = EditorStyles.label.CalcSize( label );
             EditorGUIUtility.labelWidth = Mathf.Max( labelSize.x + 5, 0.3f * fieldRect.width );
             result[i]                   = fieldDrawer( fieldRect, label, vector[i] );
             fieldRect.x                += fieldRect.width;
         }
 
         EditorGUIUtility.labelWidth = 0;
 
         return result;
     }
 }

In your main script

     [VectorLabels("Foo", "Bar")]
     public Vector3 Vector;

     [VectorLabels("My axis", "Other axis")]
     public Vector2 Vector2;
