MixedValueScope

描述

Creates a group of controls that can visually represent a mixed value.

To configure a group of controls that can show a dash (-) if selected objects have different values, add `EditorGUI.MixedValueScope` before the group and set newMixedValue to true.

using UnityEditor;
using UnityEngine;

[CanEditMultipleObjects]
[CustomEditor(typeof(MixedValueComponentTest))]
public class MixedValueComponentTestEditor : Editor
{
    public override void OnInspectorGUI()
    {
        SerializedProperty serializedPropertyMyInt = serializedObject.FindProperty("MyInt");
        using (new EditorGUI.MixedValueScope(serializedPropertyMyInt.hasMultipleDifferentValues))
        {
            EditorGUI.BeginChangeCheck();
            int newValue = EditorGUILayout.IntField("My Int", serializedPropertyMyInt.intValue);
            if (EditorGUI.EndChangeCheck())
                serializedPropertyMyInt.intValue = newValue;
        }
        serializedObject.ApplyModifiedProperties();
    }
}

public class MixedValueComponentTest : MonoBehaviour
{
    public int MyInt;
}
