This feature includes the stamina feature, and includes as a package abilities that automatically add stamina and others to trigger the addition (just like mana has currently).

IMPORTANT: This feature (as well as others that change the stats enum) will remove every stats in you game, this includes: monsters, some abilities, heros, save (bonus stats) etc. I advice following this guide so that you don’t ever have this problem:

Change “Stats.cs”

(1) Add the following param to the “EStat” enum

    public enum EStat
    {
       ... //others
        Stamina = 8
    }

Add (+1) to the “StatCount” variable:

    public class Stats
    {
        public const int StatCount = 9; //changed from 8 to 9
      ... 
     }

Change “ActiveAbilitySheet.cs”:

Add the following:

        [SerializeField] private int m_staminaCost = 0;
        public int staminaCost => m_staminaCost;

Change “ActiveAbilityBase.cs”

Add param to the enum:

    public enum EAbilityFireCheckResult
    {
        //others
        NotEnoughStamina //add this
    }

Add inside the “Fire” method after the “ConsumeMana();”:

public void Fire(UnityAction onAbilityEnded)
{
  //..othercode
    ConsumeStamina(); //add this
  //..othercode
}

Add the “ConsumeStamina” method after the (ConsumeMana) method

  protected virtual void ConsumeStamina()
  {
      m_character.ConsumeStamina(abilitySheet.staminaCost);
  }

Inside method “CanFire()” before the “return” add:

if (m_character.currentStats[EStat.Stamina] < abilitySheet.staminaCost)
{
    return EAbilityFireCheckResult.NotEnoughStamina;
}

//return EAbilityFireCheckResult.Valid; (before this return)

Change CharacterBase.cs

Add the following, after the method “ConsumeMana”:

public void RecoverStamina(int value, EEffectVisualFlags visualFlags = EEffectVisualFlags.None)
{
    int missingStamina = m_stats[EStat.Stamina] - m_currentStats[EStat.Stamina];
    m_currentStats[EStat.Stamina] += math.min(value, missingStamina);
    //GameManager.NotificationSystem.manaRecovered.Invoke(this, value, visualFlags); (this is optional)
}
public void ConsumeStamina(int value, EEffectVisualFlags visualFlags = EEffectVisualFlags.None)
{
    m_currentStats[EStat.Stamina] -= math.min(value, m_currentStats[EStat.Stamina]);
    //GameManager.NotificationSystem.staminaConsumed.Invoke(this, value, visualFlags); (this is optional)
}

UI Bar

For the UI, just open the prefab “User Interface”, inside of “HUD->Resources Bars” duplicate one of the bars and change it’s name to “Stamina Bar”. In the inspector, change the stat to Stamina [image in attachment] Also, change the “Stamina Bar->Slider->Fill Area-> Fill” background image to the green one [image in attachment]

Translations

Change the config file “CFG_Game” in “Demo->Database->Config”, include the following in both placed like you see in the images

Finally install this package!

Let me know if anything goes wrong!
