Bug RangeAttribute slider broken for negative values

Hi!

I think the Unity Editor switched to using only UI Toolkit for it's inspector a view releases ago (2022.3f1 I believe, not sure). In any case: Since then, RangeSliders that involve a negative number are broken.

Just slap this MonoBehaviour onto a GameObject and observe that the 3 sliders have broken initial states. If you click on them they will work correctly UNTIL you click away and back on the GameObject, which will break it again.

Code (CSharp):

1. using UnityEngine;
2. public class RangeSliderTest : MonoBehaviour
3. {
4.     [SerializeField, Range(-1f, 0f)] private float rangeMinus1To0;
5.     [SerializeField, Range(0f, 1f)] private float range0To1;
6.     [SerializeField, Range(-1f, 1f)] private float rangeMinus1To1;
7.     [SerializeField, Range(0, 100f)] private float range0To100;
8.     [SerializeField, Range(-100f, 100f)] private float rangeMinus100To100;
9. }

 

Thanks for the reply! I reported it (IN-34646)

 

5 months later and still broken in 2022.3.0f1.
Here's a script that provides a replacement for anyone that needs it.

Code (CSharp):

1. using UnityEngine;
2.  
3. #if UNITY_EDITOR
4. using UnityEditor;
5. #endif
6.  
7. public class MRangeAttribute : PropertyAttribute
8. {
9.     public float Min { get; }
10.     public float Max { get; }
11.  
12.     public MRangeAttribute(float min, float max)
13.     {
14.         this.Min = min;
15.         this.Max = max;
16.     }
17.  
18. #if UNITY_EDITOR
19.     [CustomPropertyDrawer(typeof(MRangeAttribute))]
20.     public class Drawer : PropertyDrawer
21.     {
22.         public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
23.         {
24.             return EditorGUIUtility.singleLineHeight;
25.         }
26.  
27.         public override void OnGUI(Rect rect, SerializedProperty property, GUIContent label)
28.         {
29.             var attribute = base.attribute as MRangeAttribute;
30.  
31.             EditorGUI.BeginProperty(rect, label, property);
32.  
33.             switch (property.propertyType)
34.             {
35.                 case SerializedPropertyType.Float:
36.                     property.floatValue = EditorGUI.Slider(rect, label, property.floatValue, attribute.Min, attribute.Max);
37.                     break;
38.  
39.                 case SerializedPropertyType.Integer:
40.                     property.floatValue = EditorGUI.IntSlider(rect, label, property.intValue, (int)attribute.Min, (int)attribute.Max);
41.                     break;
42.  
43.                 default:
44.                     EditorGUI.HelpBox(rect, $"Property ({property.name}) of type ({property.propertyType}) not Supported by MRange", MessageType.Error);
45.                     break;
46.             }
47.  
48.             EditorGUI.EndProperty();
49.         }
50.     }
51. #endif
52. }

 

Thank you, just downloaded that version.
