        if (property.propertyType == SerializedPropertyType.Integer)
        {
            int v = EditorGUI.IntField(position, label, property.intValue);
            property.intValue = (int)Mathf.Max(v, attribute.min);
        }
        else if (property.propertyType == SerializedPropertyType.Float)
        {
            float v = EditorGUI.FloatField(position, label, property.floatValue);
            property.floatValue = Mathf.Max(v, attribute.min);
        }
        else
        {
            EditorGUI.LabelField(position, label.text, "Use Min with float or int.");
        }
    }
}
