Code inspection: Incorrect Odin's group attribute type

This inspection ensures consistency across group definitions for class members when using Odin Inspector grouping attributes.

How it works

In Odin Inspector, a group must have a consistent type. Defining the same group path with different attribute types (e.g., mixing BoxGroup and HorizontalGroup for the same path) is ambiguous and can lead to unpredictable layout behavior in the Unity Inspector.

The analyzer collects all grouping attributes within a class and identifies conflicts where a specific group path (e.g., "General/Settings") is associated with more than one type of attribute. If a member uses an attribute that differs from the one already established for that group path, it flags the attribute name and suggests the expected attribute.

Example

In this example, field1 defines "MyGroup" as a BoxGroup, but field2 incorrectly attempts to use HorizontalGroup for the same path. The quick-fix changes the attribute to match the rest of the group.

                public class MyScript : MonoBehaviour
                {
                    [BoxGroup("MyGroup")]
                    public int field1;

                    // Reported: Group "MyGroup" is already defined as BoxGroup
                    [HorizontalGroup("MyGroup")]
                    public int field2;
                }
            

                public class MyScript : MonoBehaviour
                {
                    [BoxGroup("MyGroup")]
                    public int field1;

                    // After fix: Attribute corrected to match the group definition
                    [BoxGroup("MyGroup")]
                    public int field2;
                }
