完成了技能树上的格挡技能的UI逻辑

Parry_SKill.cs

核心功能

代码主要围绕以下功能展开：

（1）技能解锁

通过绑定解锁按钮的点击事件（onClick），来解锁技能。
每个技能都依赖一个 UI_SKillTreeSlot（可能是一个技能树的 UI 元素），通过检测其 unlocked 属性判断技能是否解锁成功。

（2）技能效果

a. 使用技能 (UseSkill)

在技能使用时，检查特定效果是否已解锁，并执行对应功能。
恢复生命值的功能：

b. 格挡幻影 (MakeMirageOnParry)

如果 parrtWithMirageUnlocked 解锁，生成一个幻影（类似分身）：

UI逻辑：

UI_SKillTreeSlot 是解锁按钮的一个组件，应该包括：

一个布尔变量 unlocked 表示当前技能是否解锁。
一个 Button 组件用作解锁触发点。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class Parry_SKill : Skill
{[Header("反击")]//parry[SerializeField] private UI_SKillTreeSlot parryUnlockButton;public bool parryUnlocked{ get; private set; }[Header("反击恢复")]//Parry restor[SerializeField] private UI_SKillTreeSlot restorUnlockButton;[Range(0f,1f)][SerializeField] private float restoreHealthPercentage;public bool restorUnlocked{ get; private set; }[Header("格挡幻影")]//Parry mirrage[SerializeField] private UI_SKillTreeSlot parrtWithMirageUnlockButton;public bool parrtWithMirageUnlocked { get; private set; }public override void UseSkill(){base.UseSkill();if(restorUnlocked){int restoreAmount = Mathf.RoundToInt(player.stats.GetMaxHealthValue() * restoreHealthPercentage);player.stats.IncreaseHealthBy(restoreAmount);}}protected override void Start(){base.Start();parryUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockParry);restorUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockParryRestor);parrtWithMirageUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockParrtWithMirage);}private void UnlockParry(){if (parryUnlockButton.unlocked)parryUnlocked = true;}private void UnlockParryRestor(){if (restorUnlockButton.unlocked)restorUnlocked = true;}private void UnlockParrtWithMirage(){if (parrtWithMirageUnlockButton.unlocked)parrtWithMirageUnlocked = true;}public void MakeMirageOnParry(Transform _respawnTransform){if (parrtWithMirageUnlocked)SkillManager.instance.clone.CreateCloneWithDelay(_respawnTransform);}
}

PlayerGroundedState.cs

修改了格挡技能Q的逻辑判断

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerGroundedState : PlayerState
{public PlayerGroundedState(Player _player, PlayerStateMachine _stateMachine, string _animBoolName) : base(_player, _stateMachine, _animBoolName){}public override void Enter(){base.Enter();}public override void Exit(){base.Exit();}public override void Update(){base.Update();if (Input.GetKeyDown(KeyCode.R))stateMachine.ChangeState(player.blackHole);if (Input.GetKeyDown(KeyCode.Mouse1) && HasNoSword())stateMachine.ChangeState(player.aimSword);if (Input.GetKeyDown(KeyCode.Q) && player.skill.parry.parryUnlocked)stateMachine.ChangeState(player.counterAttack);if (Input.GetKeyDown(KeyCode.Mouse0))//GetKeyDown改成GetKey按住就可以攻击了stateMachine.ChangeState(player.primaryAttack);if (!player.IsGroundDetected())stateMachine.ChangeState(player.airState);if (Input.GetKeyDown(KeyCode.Space) && player.IsGroundDetected())stateMachine.ChangeState(player.jumpState);}private bool HasNoSword(){if (!player.sword){return true;}player.sword.GetComponent<Sword_Skill_Controller>().ReturnSword();return false;}
}

PlayerCounterAttackState.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerCounterAttackState : PlayerState
{private bool canCreateClone;public PlayerCounterAttackState(Player _player, PlayerStateMachine _stateMachine, string _animBoolName) : base(_player, _stateMachine, _animBoolName){}public override void Enter(){base.Enter();canCreateClone = true;stateTimer = player.counterAttackDuration;player.anim.SetBool("SuccessfulCounterAttack", false);}public override void Exit(){base.Exit();}public override void Update(){base.Update();player.SetZeroVelocity();Collider2D[] colliders = Physics2D.OverlapCircleAll(player.attackCheck.position, player.attackCheckRadius);//这行代码在 Unity 中用于检测一个圆形区域内的所有碰撞体，并返回它们的数组。foreach (var hit in colliders)//foreach循环是一个迭代器，它可以遍历数组、集合、列表、字典等数据结构。攻击到敌人后，调用伤害函数{if (hit.GetComponent<Enemy>() != null){if (hit.GetComponent<Enemy>().CanBeStunned()){stateTimer = 10;//大于1的数，保证不会进入idle状态player.anim.SetBool("SuccessfulCounterAttack", true);player.skill.parry.UseSkill();if (canCreateClone){canCreateClone = false; player.skill.parry.MakeMirageOnParry(hit.transform);}}}}if (stateTimer < 0 || triggerCalled)stateMachine.ChangeState(player.idleState);}
}

Dash_Skill.cs

修改了一些变量

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;//2024年11月19日添加解锁技能逻辑
public class Dash_Skill : Skill
{[Header("Dash")][SerializeField] private UI_SKillTreeSlot dashUnlockButton;public bool dashUnlocked { get; private set; }[Header("Clone on dash")][SerializeField] private UI_SKillTreeSlot cloneOnDashUnlockButton;public bool cloneOmDashUnlocked { get; private set; }[Header("Clone on arrival")][SerializeField] private UI_SKillTreeSlot cloneOnArrivalUnlockButton;public bool cloneOnArrivalUnlocked { get; private set; }public override void UseSkill(){base.UseSkill();}protected override void Start(){base.Start();dashUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockDash);cloneOnDashUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockCloneOnDash);cloneOnArrivalUnlockButton.GetComponent<Button>().onClick.AddListener(UnlockCloneOnArrival);}private void UnlockDash(){if (dashUnlockButton.unlocked)   dashUnlocked = true;}private void UnlockCloneOnDash(){if (cloneOnDashUnlockButton.unlocked)cloneOmDashUnlocked = true;}private void UnlockCloneOnArrival(){if (cloneOnArrivalUnlockButton.unlocked)cloneOnArrivalUnlocked = true;}public void CloneOnDash(){if (cloneOmDashUnlocked)SkillManager.instance.clone.CreateClone(player.transform, Vector3.zero);}public void CloneOnArrival(){if (cloneOnArrivalUnlocked)SkillManager.instance.clone.CreateClone(player.transform, Vector3.zero);}}
