Unity黑魂学习笔记P16 Weapon Stamina Drain

数据部分

在WeaponItem里新增体力衰减的数据

        [Header("Weapon Stamina")]
        public float baseStamina; //20
        public float lightAttackMultiplier; //1
        public float heavyAttackMultiplier; //2

逻辑实现

我们的PlayerStats记录了玩家的各个数据，包括血量以及体力等。
PlayerAttacker是实现玩家攻击的脚本。
WeaponSlotManager是管理Item的脚本。
在WeaponSlotManager中进行实际的逻辑执行

        #region Handle Stamina Drainage
        public void DrainStaminaLightAttack()
        {
            playerStats.TakeStaminaDamage(Mathf.RoundToInt(attackingWeapon.baseStamina * attackingWeapon.lightAttackMultiplier));
        }

        public void DrainStaminaHeavyAttack()
        {
            playerStats.TakeStaminaDamage(Mathf.RoundToInt(attackingWeapon.baseStamina * attackingWeapon.heavyAttackMultiplier));
        }
        #endregion

在PlayerStats中完成数值计算

        public void TakeStaminaDamage(int damage)
        {
            currentStamina = currentStamina - damage;
            //Set Bar
            staminaBar.SetCurrentStamina(currentStamina);
        }

在StaminaBar中完成UI的更新

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class StaminaBar : MonoBehaviour
{
    public Slider slider;
    private void Start()
    {
        slider = GetComponent<Slider>();
    }
    public void SetMaxStamina(int maxStamina)
    {
        slider.maxValue = maxStamina;
        slider.value = maxStamina;
    }
    public void SetCurrentStamina(int currentStamina)
    {
        slider.value = currentStamina;
    }
}
