Instantiate class and set properties from the editor view Unity C#

I have the following class :

[Serializable]
public class BaseDamage : MonoBehaviour
{
    public int MaximumDamage;
    public int MinimumDamage;
    public short SpellScaling;
}

and a class which contains that class :

public class SpellDamage : MonoBehaviour
{
    public BaseDamage SpellBaseDamage;
}

When I attach SpellDamage script to a gameObject I want to be able to set the value of BaseDamage from the editor view, but it just allows me to attach a script to it.

how can i do that ?

You are on the right track. You can attach the BaseDamage script to the same gameobject which SpellDamage script is attached to.

You've added the Serializable attribute. What you need to do is write a Custom Property Drawer for BaseDamage class inside Editor folder.

Something like this:

[CustomPropertyDrawer(typeof(BaseDamage))]
public class BaseDamageDrawer : PropertyDrawer
{


static string[] propNames = new[]
{
    "MaximumDamage",
    "MinimumDamage",
    "SpellScaling",
};



public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
    // Using BeginProperty / EndProperty on the parent property means that
    // prefab override logic works on the entire property.
    EditorGUI.BeginProperty(position, label, property);

    // Draw label
    position = EditorGUI.PrefixLabel(position, GUIUtility.GetControlID(FocusType.Passive), label);

    // Don't make child fields be indented
    var indent = EditorGUI.indentLevel;
    EditorGUI.indentLevel = 0;

    SerializedProperty[] props = new SerializedProperty[propNames.Length];
    for (int i = 0; i < props.Length; i++)
    {
        props[i] = property.FindPropertyRelative(propNames[i]);
    }


    // Calculate rects
    float x = position.x;
    float y = position.y;
    float w = position.width / props.Length;
    float h = position.height;
    for (int i = 0; i < props.Length; i++)
    {
        var rect = new Rect(x, y, w, h);
        EditorGUI.PropertyField(rect, props[i], GUIContent.none);
        x += position.width / props.Length;
    }

    // Set indent back to what it was
    EditorGUI.indentLevel = indent;

    EditorGUI.EndProperty();
}
