unity游戏开发之–人物打怪爆材料–拾进背包的实现思路

游戏实现：unity c#

1、敌人（怪物）的生命值和伤害系统

using UnityEngine;
using System.Collections.Generic;public class Enemy : MonoBehaviour
{[Header("基础属性")]public float maxHealth = 100f;public float currentHealth;[Header("掉落物品配置")]public List<DropItem> possibleDrops;  // 可能掉落的物品列表public float dropRadius = 1f;         // 掉落物品散布半径private bool isDead = false;[System.Serializable]public class DropItem{public GameObject itemPrefab;     // 物品预制体public float dropRate;            // 掉落概率(0-1)public int minQuantity = 1;       // 最小掉落数量public int maxQuantity = 1;       // 最大掉落数量}void Start(){currentHealth = maxHealth;}// 受到伤害的方法public void TakeDamage(float damage){if (isDead) return;currentHealth -= damage;// 播放受伤动画或特效PlayHitEffect();// 检查是否死亡if (currentHealth <= 0){Die();}}private void PlayHitEffect(){// 这里可以实现受伤特效，比如闪红、粒子效果等// 示例：改变材质颜色StartCoroutine(FlashRed());}private System.Collections.IEnumerator FlashRed(){SpriteRenderer sprite = GetComponent<SpriteRenderer>();if (sprite != null){Color originalColor = sprite.color;sprite.color = Color.red;yield return new WaitForSeconds(0.1f);sprite.color = originalColor;}}private void Die(){isDead = true;// 生成掉落物品DropLoot();// 播放死亡动画StartCoroutine(PlayDeathAnimation());}private void DropLoot(){foreach (DropItem item in possibleDrops){// 根据掉落概率决定是否掉落if (Random.value <= item.dropRate){// 确定掉落数量int quantity = Random.Range(item.minQuantity, item.maxQuantity + 1);for (int i = 0; i < quantity; i++){// 在随机位置生成物品Vector2 randomOffset = Random.insideUnitCircle * dropRadius;Vector3 dropPosition = transform.position + new Vector3(randomOffset.x, randomOffset.y, 0);GameObject droppedItem = Instantiate(item.itemPrefab, dropPosition, Quaternion.identity);// 添加一些物理效果使物品散开if (droppedItem.TryGetComponent<Rigidbody2D>(out Rigidbody2D rb)){float force = 3f;Vector2 randomDirection = Random.insideUnitCircle.normalized;rb.AddForce(randomDirection * force, ForceMode2D.Impulse);}}}}}private System.Collections.IEnumerator PlayDeathAnimation(){// 这里可以播放死亡动画// 示例：简单的缩小消失效果float duration = 1f;float elapsed = 0f;Vector3 originalScale = transform.localScale;while (elapsed < duration){elapsed += Time.deltaTime;float t = elapsed / duration;transform.localScale = Vector3.Lerp(originalScale, Vector3.zero, t);yield return null;}// 销毁游戏对象Destroy(gameObject);}
}

2、掉落物品的基类

using UnityEngine;public class DroppedItem : MonoBehaviour
{[Header("物品基础属性")]public string itemName;public string itemDescription;public Sprite itemIcon;public ItemType itemType;[Header("物品行为设置")]public float attractDistance = 3f;     // 开始吸引的距离public float attractSpeed = 5f;        // 吸引速度public float bobSpeed = 2f;            // 上下浮动速度public float bobHeight = 0.2f;         // 浮动高度private Transform player;private Vector3 startPosition;private float bobTime;private bool isAttracting = false;public enum ItemType{Material,    // 材料Equipment,   // 装备Consumable   // 消耗品}void Start(){// 查找玩家player = GameObject.FindGameObjectWithTag("Player").transform;startPosition = transform.position;// 添加掉落时的物理效果AddInitialForce();}void Update(){if (player == null) return;float distanceToPlayer = Vector2.Distance(transform.position, player.position);// 当玩家靠近时，物品会被吸引if (distanceToPlayer < attractDistance){isAttracting = true;Vector3 direction = (player.position - transform.position).normalized;transform.position += direction * attractSpeed * Time.deltaTime;// 如果非常接近玩家，触发拾取if (distanceToPlayer < 0.5f){OnPickup();}}else if (!isAttracting){// 上下浮动动画bobTime += Time.deltaTime;float bobOffset = Mathf.Sin(bobTime * bobSpeed) * bobHeight;transform.position = startPosition + new Vector3(0f, bobOffset, 0f);}}private void AddInitialForce(){if (TryGetComponent<Rigidbody2D>(out Rigidbody2D rb)){// 添加随机的初始力float forceMagnitude = Random.Range(2f, 4f);Vector2 forceDirection = new Vector2(Random.Range(-1f, 1f),Random.Range(0.5f, 1f)).normalized;rb.AddForce(forceDirection * forceMagnitude, ForceMode2D.Impulse);}}private void OnPickup(){// 将物品添加到玩家背包if (player.TryGetComponent<Inventory>(out Inventory inventory)){inventory.AddItem(new ItemData{itemName = itemName,itemDescription = itemDescription,itemIcon = itemIcon,itemType = itemType});}// 播放拾取效果PlayPickupEffect();// 销毁掉落物品对象Destroy(gameObject);}private void PlayPickupEffect(){// 这里可以添加拾取特效，如粒子效果、声音等// 示例：创建一个简单的闪光效果GameObject effect = new GameObject("PickupEffect");effect.transform.position = transform.position;// 添加粒子系统（这里只是示例，实际使用时应该使用预制体）ParticleSystem particles = effect.AddComponent<ParticleSystem>();var main = particles.main;main.startLifetime = 0.5f;main.startSize = 0.5f;// 自动销毁特效对象Destroy(effect, 1f);}
}// 用于传递物品数据的结构
[System.Serializable]
public struct ItemData
{public string itemName;public string itemDescription;public Sprite itemIcon;public DroppedItem.ItemType itemType;
}

3、物品管理系统（背包系统）

using UnityEngine;
using System.Collections.Generic;
using UnityEngine.Events;public class Inventory : MonoBehaviour
{[System.Serializable]public class InventoryItem{public ItemData itemData;public int quantity;}[Header("背包设置")]public int maxInventorySlots = 20;[Header("事件")]public UnityEvent<InventoryItem> onItemAdded;public UnityEvent<InventoryItem> onItemRemoved;public UnityEvent onInventoryChanged;private List<InventoryItem> items = new List<InventoryItem>();// 添加物品到背包public bool AddItem(ItemData newItem){// 检查是否已有该物品InventoryItem existingItem = items.Find(item => item.itemData.itemName == newItem.itemName);if (existingItem != null){// 增加已有物品数量existingItem.quantity++;onItemAdded?.Invoke(existingItem);onInventoryChanged?.Invoke();return true;}else if (items.Count < maxInventorySlots){// 添加新物品InventoryItem inventoryItem = new InventoryItem{itemData = newItem,quantity = 1};items.Add(inventoryItem);onItemAdded?.Invoke(inventoryItem);onInventoryChanged?.Invoke();return true;}// 背包已满Debug.Log("背包已满！");return false;}// 从背包移除物品public bool RemoveItem(string itemName, int quantity = 1){InventoryItem item = items.Find(i => i.itemData.itemName == itemName);if (item != null){item.quantity -= quantity;if (item.quantity <= 0){items.Remove(item);}onItemRemoved?.Invoke(item);onInventoryChanged?.Invoke();return true;}return false;}// 检查是否拥有足够数量的物品public bool HasItem(string itemName, int quantity = 1){InventoryItem item = items.Find(i => i.itemData.itemName == itemName);return item != null && item.quantity >= quantity;}// 获取物品数量public int GetItemCount(string itemName){InventoryItem item = items.Find(i => i.itemData.itemName == itemName);return item?.quantity ?? 0;}// 获取所有物品public List<InventoryItem> GetAllItems(){return new List<InventoryItem>(items);}
}

实现这个系统的关键点和注意事项：
