Hi everyone,

A Patron is asking how we hide unboosted stats in the UI window. You can update the UpdateStatFields() function with the following line (highlighted in green):

    public void UpdateStatFields()
    {
        if (!player) return;

        // Get a reference to both Text objects to render stat names and stat values.
        if (!statNames) statNames = transform.GetChild(0).GetComponent<TextMeshProUGUI>();
        if (!statValues) statValues = transform.GetChild(1).GetComponent<TextMeshProUGUI>();

        // Render all stat names and values.
        // Use StringBuilders so that the string manipulation runs faster.
        StringBuilder names = new StringBuilder();
        StringBuilder values = new StringBuilder();

        // Add the current health to the stat box.
        if(displayCurrentHealth)
        {
            names.AppendLine("Health");
            values.AppendLine(player.CurrentHealth.ToString());
        }

        FieldInfo[] fields = typeof(CharacterData.Stats).GetFields(BindingFlags.Public | BindingFlags.Instance);
        foreach (FieldInfo field in fields)
        {
            // Render stat names.
            names.AppendLine(field.Name);

            // Get the stat value.
            object val = field.GetValue(player.Stats);
            float fval = val is int ? (int)val : (float)val;

            // Print it as a percentage if it has an attribute assigned and is a float.
            PropertyAttribute attribute = (PropertyAttribute)PropertyAttribute.GetCustomAttribute(field, typeof(PropertyAttribute));
            if (attribute != null && field.FieldType == typeof(float))
            {
                float percentage = Mathf.Round(fval * 100 - 100);

                // If the stat value is 0, just put a dash.
                if (Mathf.Approximately(percentage, 0))
                {
                    values.Append('-').Append('\n');
                }
                else
                {
                    if (percentage > 0)
                        values.Append('+');
                    values.Append(percentage).Append('%').Append('\n');
                }
            }
            else
            {
                if(Mathf.Approximately(fval, 1)) values.Append('-').Append('\n');
                else values.Append(fval).Append('\n');
            }

            // Updates the fields with the strings we built.
            statNames.text = PrettifyNames(names);
            statValues.text = values.ToString();
        }
    }
