本期紧接着上一篇主要内容主要是实现不同炮塔、攻击行为逻辑和伤害飘字效果。
绘制炮塔UI 新增炮塔脚本配置炮塔攻击范围
[RequireComponent(typeof(CircleCollider2D))]
public class Turret : MonoBehaviour
{[SerializeField] private float attackRange 3f; // 视为攻击范围private bool _gameStarted; // 游戏是否已经开始private void Start(){_gameStarted true; // 设置游戏为已开始状态}private void OnDrawGizmos(){if (!_gameStarted){// 在Scene视图中绘制攻击范围的可视化表示GetComponentCircleCollider2D().radius attackRange; // 设置CircleCollider2D的半径为攻击范围Gizmos.DrawWireSphere(transform.position, attackRange); // 在指定位置绘制表示攻击范围的线框球体}}
}炮塔转向敌人
修改Turret
public class Turret : MonoBehaviour
{//...public Enemy CurrentEnemyTarget { get; set; }private ListEnemy _enemies;private void Start(){_gameStarted true; // 设置游戏为已开始状态_enemies new ListEnemy();}private void Update(){GetCurrentEnemyTarget();RotateTowardsTarget();}//获取当前敌人目标private void GetCurrentEnemyTarget(){if (_enemies.Count 0){CurrentEnemyTarget null;return;}CurrentEnemyTarget _enemies[0];}//面向敌人private void RotateTowardsTarget(){if (CurrentEnemyTarget null) return;Vector3 targetPos CurrentEnemyTarget.transform.position - transform.position;float angle Vector3.SignedAngle(transform.up, targetPos, transform.forward);transform.Rotate(0f, 0f, angle);}private void OnTriggerEnter2D(Collider2D other){if (other.CompareTag(Enemy)){Enemy newEnemy other.GetComponentEnemy();_enemies.Add(newEnemy);}}private void OnTriggerExit2D(Collider2D other){if (other.CompareTag(Enemy)){Enemy enemy other.GetComponentEnemy();if (_enemies.Contains(enemy)){_enemies.Remove(enemy);}};}//...
}记得修改敌人标签添加刚体和碰撞体
效果进入范围获取了目标,敌人超出范围不再跟随
生成炮弹
新增Projectile子弹控制脚本
public class Projectile : MonoBehaviour
{[SerializeField, Header(子弹移动速度)] private float moveSpeed 10f;private Enemy _enemyTarget; // 目标敌人private void Update(){if (_enemyTarget ! null){MoveProjectile();}}private void MoveProjectile(){// 将子弹向目标位置移动transform.position Vector2.MoveTowards(transform.position,_enemyTarget.transform.position,moveSpeed * Time.deltaTime);}public void SetEnemy(Enemy enemy){// 设置目标敌人_enemyTarget enemy;}
}制作子弹预制体并挂载Projectile 脚本 新增TurretProjectile控制子弹生成脚本
public class TurretProjectile : MonoBehaviour
{[SerializeField] private Transform projectileSpawnPosition; // 发射子弹的位置private ObjectPooler pooler; // 对象池管理器private Turret _turret;// 炮塔组件private Projectile _currentProjectileLoaded;// 当前装载的子弹private void Start(){pooler GetComponentObjectPooler(); // 获取对象池管理器组件_turret GetComponentTurret();}private void Update(){if (Input.GetKeyDown(KeyCode.G)){LoadProjectile(); // 测试按下G键时加载子弹}// 如果有敌人目标、已加载子弹且敌人目标的健康值大于0if (_turret.CurrentEnemyTarget ! null _currentProjectileLoaded ! null _turret.CurrentEnemyTarget._enemyHealth.CurrentHealth 0f){// 解除子弹的父节点关系_currentProjectileLoaded.transform.parent null;// 设置子弹的目标敌人_currentProjectileLoaded.SetEnemy(_turret.CurrentEnemyTarget);}}private void LoadProjectile(){GameObject newInstance pooler.GetInstanceFromPool(); // 从对象池获取一个新的子弹实例newInstance.transform.localPosition projectileSpawnPosition.position; // 设置子弹的位置为发射位置newInstance.transform.SetParent(projectileSpawnPosition); // 设置子弹的父节点为发射位置_currentProjectileLoaded newInstance.GetComponentProjectile();// 获取子弹组件newInstance.SetActive(true); // 激活子弹}
}挂载脚本并配置参数 效果
旋转我们的子弹
修改Projectile
private void Update()
{if (_enemyTarget ! null){MoveProjectile();RotateProjectile();}
}//控制子弹自动旋转
private void RotateProjectile()
{Vector3 enemyPos _enemyTarget.transform.position - transform.position; // 计算目标敌人相对于子弹的位置向量float angle Vector3.SignedAngle(transform.up, enemyPos, transform.forward); // 计算旋转角度transform.Rotate(0f, 0f, angle); // 绕Z轴旋转子弹
}效果
对敌人造成伤害回收子弹
修改Projectile
[SerializeField, Header(子弹造成的伤害值)]
private float damage 2f;
[SerializeField, Header(造成伤害的距离)]
private float minDistanceToDealDamage 0.1f;private void MoveProjectile()
{// 将子弹向目标位置移动//...// 计算子弹与目标的距离float distanceToTarget (_enemyTarget.transform.position - transform.position).magnitude;// 如果子弹与目标的距离小于最小距离造成伤害并回收子弹if (distanceToTarget minDistanceToDealDamage){_enemyTarget._enemyHealth.DealDamage(damage);ObjectPooler.ReturnToPool(gameObject);}
}效果
自动发射子弹
修改Projectile
public TurretProjectile Turretowner { get; set; }private void MoveProjectile()
{// ...// 如果子弹与目标的距离小于最小距离造成伤害并回收子弹if (distanceToTarget minDistanceToDealDamage){Turretowner.ResetTurretProjectile(); //重置装载的子弹//...}
}修改TurretProjectile
private void Update()
{if(IsTurretEmpty() _turret.CurrentEnemyTarget ! null){LoadProjectile();}//...
}
//加载子弹
private void LoadProjectile()
{//..._currentProjectileLoaded.Turretowner this;
}//判断是否没有装载子弹
private bool IsTurretEmpty()
{return _currentProjectileLoaded null;
}//重置装载的子弹
public void ResetTurretProjectile()
{_currentProjectileLoaded null;
}添加攻击间隔
修改TurretProjectile
[SerializeField, Header(攻击间隔)]
private float delayBtwAttacks 2f;//攻击间隔private float nextAttackTime;//下一次攻击时间private void Update()
{if (Time.time nextAttackTime){// 如果有敌人目标、已加载子弹且敌人目标的健康值大于0if (_turret.CurrentEnemyTarget ! null _turret.CurrentEnemyTarget._enemyHealth.CurrentHealth 0f){LoadProjectile();// 解除子弹的父节点关系_currentProjectileLoaded.transform.parent null;// 设置子弹的目标敌人_currentProjectileLoaded.SetEnemy(_turret.CurrentEnemyTarget);}nextAttackTime Time.time delayBtwAttacks;}//加载子弹private void LoadProjectile(){//。。。_currentProjectileLoaded.ResetProjectile();//重置炮弹}
}修改Projectile
//重置炮弹
public void ResetProjectile()
{_enemyTarget null;transform.localRotation Quaternion.identity;
}效果每两秒发动一次攻击
显示伤害字体
绘制字体UI
配置动画这个动画就大家自由发挥吧怎么放大缩小或者上飘
新增脚本DamageText
public class DamageText : MonoBehaviour
{public TextMeshPro DmgText GetComponentTextMeshPro();// 回收飘字public void ReturnTextToPool(){transform.SetParent(null);ObjectPooler.ReturnToPool(gameObject);}
}挂载脚本到字体动画完成时添加事件
新增DamageTextManager
public class DamageTextManager : MonoBehaviour
{public ObjectPooler Pooler { get; set; }public DamageText damageText;//飘字特效预制体public static DamageTextManager Instance;void Awake(){Instance this;}private void Start(){Pooler GetComponentObjectPooler();}
}挂载脚本配置参数
修改Projectile添加敌人受伤委托
public static ActionEnemy, float OnEnemyHit;//敌人受伤委托private void MoveProjectile()
{// 。。。// 如果子弹与目标的距离小于最小距离造成伤害并回收子弹if (distanceToTarget minDistanceToDealDamage){OnEnemyHit?.Invoke(_enemyTarget, damage);//。。。}
}新增EnemyFX
public class EnemyFX : MonoBehaviour
{[SerializeField] private Transform textDamageSpawnPosition; // 伤害数字显示位置private Enemy _enemy; // 敌人对象private void Awake(){_enemy GetComponentEnemy(); // 获取敌人组件}// 敌人受到攻击时的处理方法private void EnemyHit(Enemy enemy, float damage){if (_enemy enemy) // 判断是否为当前敌人{GameObject newInstance DamageTextManager.Instance.Pooler.GetInstanceFromPool(); // 从对象池中获取伤害数字的实例TextMeshPro damageText newInstance.GetComponentDamageText().DmgText; // 获取伤害数字的Text组件damageText.text damage.ToString(); // 设置显示的伤害数值newInstance.transform.SetParent(textDamageSpawnPosition); // 设置父物体为伤害数字显示位置newInstance.transform.position textDamageSpawnPosition.position; // 设置显示位置newInstance.SetActive(true); // 激活显示}}private void OnEnable(){Projectile.OnEnemyHit EnemyHit; // 注册敌人被攻击事件的监听}private void OnDisable(){Projectile.OnEnemyHit - EnemyHit; // 取消注册敌人被攻击事件的监听}
}挂载脚本 效果
设计通用泛型单例
新增泛型单例
using UnityEngine;//简单的泛型单例
public class SingletonT : MonoBehaviour where T : Component
{private static T instance;public static T Instance{get{if (instance null){instance FindObjectOfTypeT();if (instance null){GameObject newInstance new GameObject();instance newInstance.AddComponentT();}}return instance;}}public void Awake(){instance this as T;}
}修改DamageTextManager 简化代码
public class DamageTextManager : SingletonDamageTextManager
{public ObjectPooler Pooler { get; set; }public DamageText damageText;//飘字特效预制体private void Start(){Pooler GetComponentObjectPooler();}
}创建更多炮塔 效果
升级增加伤害
修改TurretProjectile
[SerializeField, Header(造成的伤害值)]
protected float damage 2f;
public float Damge { get; set; }private void Start()
{//。。。Damge damage;
}//加载子弹
protected virtual void LoadProjectile()
{//。。。_currentProjectileLoaded.damage Damge;
}新增TurretUpgrade
public class TurretUpgrade : MonoBehaviour
{[SerializeField]private int upgradeInitialCost; // 升级初始费用[SerializeField]private int upgradeCostIncremental; // 升级费用递增值[SerializeField]private float damageIncremental; // 伤害递增值private TurretProjectile _turretProjectile;private void Start(){_turretProjectile GetComponentTurretProjectile(); // 获取 TurretProjectile 组件}private void Update(){if (Input.GetKeyDown(KeyCode.D)){UpgradeTurret(); // 测试升级炮塔}}private void UpgradeTurret(){_turretProjectile.Damge damageIncremental; // 增加炮塔的伤害值}
}配置参数测试
效果按一次D伤害增加2
升级缩短攻击间隔
修改TurretProjectile
public float DelayPerShot { get; set; }DelayPerShot delayBtwAttacks;protected virtual void Update()
{if (Time.time _nextAttackTime){// 。。。_nextAttackTime Time.time DelayPerShot;}
}修改TurretUpgrade
[SerializeField, Header(攻击间隔递减值)]
private float delayReduce;private void UpgradeTurret()
{_turretProjectile.Damge damageIncremental; // 增加炮塔的伤害值_turretProjectile.DelayPerShot - delayReduce;// 减少炮塔的攻击间隔
}测试配置 效果
添加货币
添加
public class CurrencySystem : SingletonCurrencySystem
{[SerializeField]private int coinTest; // 测试用的初始金币数量private string CURRENCY_SAVE_KEY MYGAME_CURRENCY;public int TotalCoins { get; set; } // 总金币数量private void Start(){PlayerPrefs.DeleteKey(CURRENCY_SAVE_KEY);//开始清空金币数据LoadCoins(); // 加载金币数量}private void LoadCoins(){TotalCoins PlayerPrefs.GetInt(CURRENCY_SAVE_KEY, coinTest); // 从 PlayerPrefs 中读取金币数量默认为 coinTest 的值}public void AddCoins(int amount){TotalCoins amount; // 增加金币数量PlayerPrefs.SetInt(CURRENCY_SAVE_KEY, TotalCoins); // 将金币数量保存到 PlayerPrefsPlayerPrefs.Save(); // 保存 PlayerPrefs 的修改}public void RemoveCoins(int amount){if (TotalCoins amount){TotalCoins - amount; // 减少金币数量PlayerPrefs.SetInt(CURRENCY_SAVE_KEY, TotalCoins); // 将金币数量保存到 PlayerPrefsPlayerPrefs.Save(); // 保存 PlayerPrefs 的修改}}
}修改TurretUpgrade
public int UpgradeCost { get; set; }private void Start()
{//。。。UpgradeCost upgradeInitialCost;
}private void UpgradeTurret()
{if (CurrencySystem.Instance.TotalCoins UpgradeCost){_turretProjectile.Damge damageIncremental; // 增加炮塔的伤害值_turretProjectile.DelayPerShot - delayReduce;// 减少炮塔的攻击间隔UpdateUpgrade();}
}private void UpdateUpgrade()
{CurrencySystem.Instance.RemoveCoins(UpgradeCost);//扣除金额UpgradeCost upgradeCostIncremental;//加下次升级金额
}配置升级消耗10每次升级消耗20
效果升级扣除了金额
杀死敌人获取金币
修改CurrencySystem每杀一个敌人加一金币
private void AddCoins(Enemy enemy)
{AddCoins(1);
}private void OnEnable()
{EnemyHealth.OnEnemyKilled AddCoins;
}
private void OnDisable()
{EnemyHealth.OnEnemyKilled - AddCoins;
}效果杀死敌人金额增加
