Unity实战案例全解析 类宝可梦回合制的初级案例 源码分析（加了注释和流程图）

这是一个老教程了，但是对于没有写过回合制的初级程序同学来讲是比较适合的，也可以直接看源码，半小时内可以解决战斗

当然，我也没写过回合制系统所以就到处找，思路明白了就能自己修改了

实现效果 

流程图 

Start进入PlayerAttack，之后便是几个枚举状态之间的循环了

主要代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;// 定义战斗状态的枚举
public enum BattleState { START, PLAYERTURN, ENEMYTURN, WON, LOST }public class BattleSystem : MonoBehaviour
{// 玩家和敌人的预制体public GameObject playerPrefab;public GameObject enemyPrefab;// 玩家和敌人的战斗位置public Transform playerBattleStation;public Transform enemyBattleStation;// 玩家和敌人的单位Unit playerUnit;Unit enemyUnit;// 对话文本public Text dialogueText;// 玩家和敌人的HUDpublic BattleHUD playerHUD;public BattleHUD enemyHUD;// 当前战斗状态public BattleState state;// Start is called before the first frame updatevoid Start(){// 初始化战斗状态为STARTstate = BattleState.START;// 启动设置战斗的协程StartCoroutine(SetupBattle());}// 设置战斗的协程IEnumerator SetupBattle(){// 实例化玩家和敌人的预制体GameObject playerGO = Instantiate(playerPrefab, playerBattleStation);playerUnit = playerGO.GetComponent<Unit>();GameObject enemyGO = Instantiate(enemyPrefab, enemyBattleStation);enemyUnit = enemyGO.GetComponent<Unit>();// 更新对话文本dialogueText.text = "A wild " + enemyUnit.unitName + " approaches...";// 设置玩家和敌人的HUDplayerHUD.SetHUD(playerUnit);enemyHUD.SetHUD(enemyUnit);// 等待2秒yield return new WaitForSeconds(2f);// 切换到玩家回合state = BattleState.PLAYERTURN;PlayerTurn();}// 玩家攻击的协程IEnumerator PlayerAttack(){// 玩家攻击敌人并检查敌人是否死亡bool isDead = enemyUnit.TakeDamage(playerUnit.damage);// 更新敌人的HP和对话文本enemyHUD.SetHP(enemyUnit.currentHP);dialogueText.text = "The attack is successful!";// 等待2秒yield return new WaitForSeconds(2f);// 如果敌人死亡，结束战斗；否则，切换到敌人回合if(isDead){state = BattleState.WON;EndBattle();} else{state = BattleState.ENEMYTURN;StartCoroutine(EnemyTurn());}}// 敌人回合的协程IEnumerator EnemyTurn(){// 更新对话文本dialogueText.text = enemyUnit.unitName + " attacks!";// 等待1秒yield return new WaitForSeconds(1f);// 敌人攻击玩家并检查玩家是否死亡bool isDead = playerUnit.TakeDamage(enemyUnit.damage);// 更新玩家的HPplayerHUD.SetHP(playerUnit.currentHP);// 等待1秒yield return new WaitForSeconds(1f);// 如果玩家死亡，结束战斗；否则，切换到玩家回合if(isDead){state = BattleState.LOST;EndBattle();} else{state = BattleState.PLAYERTURN;PlayerTurn();}}// 结束战斗的方法void EndBattle(){if(state == BattleState.WON){dialogueText.text = "You won the battle!";} else if (state == BattleState.LOST){dialogueText.text = "You were defeated.";}}// 玩家回合的方法void PlayerTurn(){dialogueText.text = "Choose an action:";}// 玩家治疗的协程IEnumerator PlayerHeal(){// 玩家恢复HPplayerUnit.Heal(5);// 更新玩家的HP和对话文本playerHUD.SetHP(playerUnit.currentHP);dialogueText.text = "You feel renewed strength!";// 等待2秒yield return new WaitForSeconds(2f);// 切换到敌人回合state = BattleState.ENEMYTURN;StartCoroutine(EnemyTurn());}// 攻击按钮的事件处理方法public void OnAttackButton(){if (state != BattleState.PLAYERTURN)return;StartCoroutine(PlayerAttack());}// 治疗按钮的事件处理方法public void OnHealButton(){if (state != BattleState.PLAYERTURN)return;StartCoroutine(PlayerHeal());}
}

次要代码

战斗单位脚本，主要是属性

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Unit : MonoBehaviour
{public string unitName;public int unitLevel;public int damage;public int maxHP;public int currentHP;public bool TakeDamage(int dmg){currentHP -= dmg;if (currentHP <= 0)return true;elsereturn false;}public void Heal(int amount){currentHP += amount;if (currentHP > maxHP)currentHP = maxHP;}}

 更新UI代码
 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class BattleHUD : MonoBehaviour
{public Text nameText;public Text levelText;public Slider hpSlider;public void SetHUD(Unit unit){nameText.text = unit.unitName;levelText.text = "Lvl " + unit.unitLevel;hpSlider.maxValue = unit.maxHP;hpSlider.value = unit.currentHP;}public void SetHP(int hp){hpSlider.value = hp;}}
