Unity3D仿星露谷物语开发22之选择道具特效

1、目标

当在库存栏中选择道具时，Slot会红色高亮，表明一个道具已被选中。再次点击道具红色高亮消失。

2、优化InventoryManager.cs脚本

（1）新建被选中项目的变量

我们允许有多个库存列表，比如属于player的即库存栏中，也有chest（未使用过）的。

库存列表位于一个按库存位置索引的数组中。

新增一个变量表明对应库存位置索引下被选中的物品code。

    private int[] selectedInventoryItem; // the index of the array is the inventory list, and the value is the item code,表明每个位置对应被选中物品的code

其在Awake中的初始化如下：

// Initialize selected inventory item array
selectedInventoryItem = new int[(int)InventoryLocation.count];for(int i = 0; i < selectedInventoryItem.Length; i++)
{selectedInventoryItem[i] = -1;
}

其中：

InventoryLocation为枚举类。
-1表示没有选中任何项目

（2）添加选中项目的函数

public void SetSelectedInventoryItem(InventoryLocation inventoryLocation, int itemCode)
{selectedInventoryItem[(int)inventoryLocation] = itemCode;  
}

（3）添加删除项目的函数

 public void ClearSelectedInventoryItem(InventoryLocation inventoryLocation){selectedInventoryItem[(int)inventoryLocation] = -1;}

此时InventoryManager.cs中的完整代码如下：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class InventoryManager : SingletonMonobehaviour<InventoryManager>
{private Dictionary<int, ItemDetails> itemDetailsDictionary;private int[] selectedInventoryItem; // the index of the array is the inventory list, and the value is the item code,表明每个位置对应被选中物品的codepublic List<InventoryItem>[] inventoryLists; // 每个位置的库存清单// 每个位置的库存数。 The index of the array is the inventory list(from the// InventoryLocation enum), and the value is the capacity of that inventory list[HideInInspector] public int[] inventoryListCapacityIntArray; [SerializeField] private SO_ItemList itemList = null;protected override void Awake(){base.Awake();// Create Inventory listsCreateInventoryLists();// Create item details dictionaryCreateItemDetailsDictionary();// Initialize selected inventory item arrayselectedInventoryItem = new int[(int)InventoryLocation.count];for(int i = 0;

}

3、优化UIInventoryBar.cs脚本

（1）清除选中高亮特效

添加Bar中清除所有选中的红色高亮框的函数：

/// <summary>
/// Clear all highlight from the inventory bar
/// </summary>
public void ClearHighlightOnInventorySlots()
{if (inventorySlot.Length > 0){// loop through inventory slots and clear highlight spritesfor (int i = 0; i < inventorySlot.Length; i++){if (inventorySlot[i].isSelected){inventorySlot[i].isSelected = false;inventorySlot[i].inventorySlotHighlight.color = new Color(0f, 0f, 0f, 0f);// Update inventory to show item as not selectedInventoryManager.Instance.ClearSelectedInventoryItem(InventoryLocation.player);}}}
}

（2）增加选中高亮特效

/// <summary>
/// Set the selected highlight if set on all inventory item positions
/// </summary>
public void SetHighlightedInventorySlots()
{if(inventorySlot.Length > 0){// loop through inventory slots and set highlight spritesfor(int i = 0; i < inventorySlot.Length; i++){SetHighlightedInventorySlots(i);}}
}/// <summary>
/// Set the selected highlight if set on an inventory item for a given slot item position
/// </summary>
/// <param name="itemPosition"></param>
public void SetHighlightedInventorySlots(int itemPosition)
{if(inventorySlot.Length > 0 && inventorySlot[itemPosition].itemDetails != null){if (inventorySlot[itemPosition].isSelected){inventorySlot[itemPosition].inventorySlotHighlight.color = new Color(1f, 1f, 1f, 1f);// Update inventory to show item as selectedInventoryManager.Instance.SetSelectedInventoryItem(InventoryLocation.player, inventorySlot[itemPosition].itemDetails.itemCode);}}
}

在InventoryUpdated函数中增加SetHighlightedInventorySlots()的调用。

此时UIInventoryBar.cs的完整代码如下：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class UIInventoryBar : MonoBehaviour
{[SerializeField] private Sprite blank16x16sprite = null; // 插槽默认图案[SerializeField] private UIInventorySlot[] inventorySlot = null; // 所有插槽集合public GameObject inventoryBarDraggedItem;[HideInInspector] public GameObject inventoryTextBoxGameobject;private RectTransform rectTransform;private bool _isInventoryBarPositionBottom = true;public bool IsInventoryBarPositionBottom { get { return _isInventoryBarPositionBottom;} set { _isInventoryBarPositionBottom = value; } }private void Awake(){rectTransform = GetComponent<RectTransform>();}private void OnDisable(){EventHandler.InventoryUpdatedEvent -= InventoryUpdated;}private void InventoryUpdated(InventoryLocation inventoryLocation, List<InventoryItem> inventoryList){if (inventoryLocation == InventoryLocation.player){ClearInventorySlots();if (inventorySlot.Length > 0 && inventoryList.Count > 0){for (int i = 0; i < inventorySlot.Length; i++){if (i < inventoryList.Count){int itemCode = inventoryList[i].itemCode;ItemDetails itemDetails = InventoryManager.Instance.GetItemDetails(itemCode);if (itemDetails != null){// add images and details to inventory item slotinventorySlot[i].inventorySlotImage.sprite = itemDetails.itemSprite;inventorySlot[i].textMeshProUGUI.text = inventoryList[i].itemQuantity.ToString();inventorySlot[i].itemDetails = itemDetails;inventorySlot[i].itemQuantity = inventoryList[i].itemQuantity;SetHighlightedInventorySlots(i);}}else{break;}}}}}private void ClearInventorySlots(){if(inventorySlot.Length > 0){// loop through inventory slots and update with blank spritefor(int i = 0; i < inventorySlot.Length; i++){inventorySlot[i].inventorySlotImage.sprite = blank16x16sprite;inventorySlot[i].textMeshProUGUI.text = "";inventorySlot[i].itemDetails = null;inventorySlot[i].itemQuantity = 0;}}}private void OnEnable(){EventHandler.InventoryUpdatedEvent += InventoryUpdated;}private void Update(){// Switch inventory bar position depending on player positionSwitchInventoryBarPosition();}private void SwitchInventoryBarPosition(){Vector3 playerViewportPosition = Player.Instance.GetPlayerViewportPosition();if (playerViewportPosition.y > 0.3f && IsInventoryBarPositionBottom == false){rectTransform.pivot = new Vector2(0.5f, 0f);rectTransform.anchorMin = new Vector2(0.5f, 0f);rectTransform.anchorMax = new Vector2(0.5f, 0f);rectTransform.anchoredPosition = new Vector2(0f, 2.5f);IsInventoryBarPositionBottom = true;}else if (playerViewportPosition.y <= 0.3f && IsInventoryBarPositionBottom == true) {rectTransform.pivot = new Vector2(0.5f, 1f);rectTransform.anchorMin = new Vector2(0.5f, 1f);rectTransform.anchorMax = new Vector2(0.5f, 1f);rectTransform.anchoredPosition = new Vector2(0f, -2.5f);IsInventoryBarPositionBottom = false;}}/// <summary>/// Clear all highlight from the inventory bar/// </summary>public void ClearHighlightOnInventorySlots(){if (inventorySlot.Length > 0){// loop through inventory slots and clear highlight spritesfor (int i = 0; i < inventorySlot.Length; i++){if (inventorySlot[i].isSelected){inventorySlot[i].isSelected = false;inventorySlot[i].inventorySlotHighlight.color = new Color(0f, 0f, 0f, 0f);// Update inventory to show item as not selectedInventoryManager.Instance.ClearSelectedInventoryItem(InventoryLocation.player);}}}}/// <summary>/// Set the selected highlight if set on all inventory item positions/// </summary>public void SetHighlightedInventorySlots(){if(inventorySlot.Length > 0){// loop through inventory slots and set highlight spritesfor(int i = 0; i < inventorySlot.Length; i++){SetHighlightedInventorySlots(i);}}}/// <summary>/// Set the selected highlight if set on an inventory item for a given slot item position/// </summary>/// <param name="itemPosition"></param>public void SetHighlightedInventorySlots(int itemPosition){if(inventorySlot.Length > 0 && inventorySlot[itemPosition].itemDetails != null){if (inventorySlot[itemPosition].isSelected){inventorySlot[itemPosition].inventorySlotHighlight.color = new Color(1f, 1f, 1f, 1f);// Update inventory to show item as selectedInventoryManager.Instance.SetSelectedInventoryItem(InventoryLocation.player, inventorySlot[itemPosition].itemDetails.itemCode);}}}
}

4、优化UIInventorySlot.cs脚本

（1）新增Slot是否被选中的变量

[HideInInspector] public bool isSelected = false;

（2）添加IPointerClickHandler处理函数

处理在Slot上的鼠标点击事件。

public void OnPointerClick(PointerEventData eventData)
{// if left clickif (eventData.button == PointerEventData.InputButton.Left){// if inventory slot currently selected then deselectif (isSelected == true){ClearSelectedItem();}else  // 未被选中且有东西则显示选中的效果{if(itemQuantity > 0){SetSelectedItem();}}}
}/// <summary>
/// Set this inventory slot item to be selected
/// </summary>
private void SetSelectedItem()
{// Clear currently highlighted itemsinventoryBar.ClearHighlightOnInventorySlots();// Highlight item on inventory barisSelected = true;// Set highlighted inventory slotsinventoryBar.SetHighlightedInventorySlots();// Set item selected in inventoryInventoryManager.Instance.SetSelectedInventoryItem(InventoryLocation.player, itemDetails.itemCode);
}private void ClearSelectedItem()
{// Clear currently highlighted iteminventoryBar.ClearHighlightOnInventorySlots();isSelected = false;// set no item selected in inventoryInventoryManager.Instance.ClearSelectedInventoryItem(InventoryLocation.player);
}

（3）修改DropSelectedItemAtMousePosition方法

private void DropSelectedItemAtMousePosition()
{if(itemDetails != null && isSelected){Vector3 worldPosition = mainCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, -mainCamera.transform.position.z));// Create item from prefab at mouse positionGameObject itemGameObject = Instantiate(itemPrefab, worldPosition, Quaternion.identity, parentItem);Item item = itemGameObject.GetComponent<Item>();item.ItemCode = itemDetails.itemCode;// Remove item from player's inventoryInventoryManager.Instance.RemoveItem(InventoryLocation.player, item.ItemCode);// If no more of item then clear selectedif(InventoryManager.Instance.FindItemInInventory(InventoryLocation.player, item.ItemCode) == -1){ClearSelectedItem();}}
}

增加isSelected的判断。

如果库存列表中不存在商品，那么增加清除红色高亮。

（4）修改OnBeginDrag函数

增加SetSelectedItem()调用。

开始拖动的时候，就可以显示红色高亮。

（5）修改OnEndDrag函数

增加ClearSelectedItem()调用。

结束拖动的时候，就可以清除红色高亮了。

此时UIInventorySlot.cs的完整代码如下：

using UnityEngine;
using TMPro;
using UnityEngine.UI;
using UnityEngine.EventSystems;
using System;public class UIInventorySlot : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler, IPointerEnterHandler, IPointerExitHandler, IPointerClickHandler
{private Camera mainCamera;private Transform parentItem; // 场景中的物体父类private GameObject draggedItem; // 被拖动的物体private Canvas parentCanvas;public Image inventorySlotHighlight;public Image inventorySlotImage;public TextMeshProUGUI textMeshProUGUI;[SerializeField] private UIInventoryBar inventoryBar = null;[SerializeField] private GameObject itemPrefab = null;[SerializeField] private int slotNumber = 0; // 插槽的序列号[SerializeField] private GameObject inventoryTextBoxPrefab = null;[HideInInspector] public ItemDetails itemDetails;[HideInInspector] public int itemQuantity;[HideInInspector] public bool isSelected = false;private void Awake(){parentCanvas = GetComponentInParent<Canvas>();}private void Start(){mainCamera = Camera.main;parentItem = GameObject.FindGameObjectWithTag(Tags.ItemsParentTransform).transform;}public void OnBeginDrag(PointerEventData eventData){if(itemDetails != null) {// Disable keyboard inputPlayer.Instance.DisablePlayerInputAndResetMovement();// Instatiate gameobject as dragged itemdraggedItem = Instantiate(inventoryBar.inventoryBarDraggedItem, inventoryBar.transform);// Get image for dragged itemImage draggedItemImage = draggedItem.GetComponentInChildren<Image>();draggedItemImage.sprite = inventorySlotImage.sprite;SetSelectedItem();}}public void OnDrag(PointerEventData eventData){// move game object as dragged itemif(!draggedItem != null){draggedItem.transform.position = Input.mousePosition;}}public void OnEndDrag(PointerEventData eventData){// Destroy game object as dragged itemif (draggedItem != null) {Destroy(draggedItem);// if drag ends over inventory bar, get item drag is over and swap thenif (eventData.pointerCurrentRaycast.gameObject != null && eventData.pointerCurrentRaycast.gameObject.GetComponent<UIInventorySlot>() != null) {// get the slot number where the drag endedint toSlotNumber = eventData.pointerCurrentRaycast.gameObject.GetComponent<UIInventorySlot>().slotNumber;// Swap inventory items in inventory listInventoryManager.Instance.SwapInventoryItems(InventoryLocation.player, slotNumber, toSlotNumber);// Destroy inventory text boxDestroyInventoryTextBox();// Clear selected itemClearSelectedItem();}else{// else attemp to drop the item if it can be droppedif (itemDetails.canBeDropped){DropSelectedItemAtMousePosition();}}// Enable player inputPlayer.Instance.EnablePlayerInput();}}/// <summary>/// Drops the item(if selected) at the current mouse position. called by the DropItem event/// </summary>private void DropSelectedItemAtMousePosition(){if(itemDetails != null && isSelected){Vector3 worldPosition = mainCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, -mainCamera.transform.position.z));// Create item from prefab at mouse positionGameObject itemGameObject = Instantiate(itemPrefab, worldPosition, Quaternion.identity, parentItem);Item item = itemGameObject.GetComponent<Item>();item.ItemCode = itemDetails.itemCode;// Remove item from player's inventoryInventoryManager.Instance.RemoveItem(InventoryLocation.player, item.ItemCode);// If no more of item then clear selectedif(InventoryManager.Instance.FindItemInInventory(InventoryLocation.player, item.ItemCode) == -1){ClearSelectedItem();}}}public void OnPointerEnter(PointerEventData eventData){// Populate text box with item detailsif(itemQuantity != 0){// Instantiate inventory text boxinventoryBar.inventoryTextBoxGameobject = Instantiate(inventoryTextBoxPrefab, transform.position, Quaternion.identity);inventoryBar.inventoryTextBoxGameobject.transform.SetParent(parentCanvas.transform, false);UIInventoryTextBox inventoryTextBox = inventoryBar.inventoryTextBoxGameobject.GetComponent<UIInventoryTextBox>();// Set item type descriptionstring itemTypeDescription = InventoryManager.Instance.GetItemTypeDescription(itemDetails.itemType);// Populate text boxinventoryTextBox.SetTextboxText(itemDetails.itemDescription, itemTypeDescription, "", itemDetails.itemLongDescription, "", "");// Set text box position according to inventory bar positionif (inventoryBar.IsInventoryBarPositionBottom){inventoryBar.inventoryTextBoxGameobject.GetComponent<RectTransform>().pivot = new Vector2(0.5f, 0f);inventoryBar.inventoryTextBoxGameobject.transform.position = new Vector3(transform.position.x, transform.position.y + 50f, transform.position.z);}else{inventoryBar.inventoryTextBoxGameobject.GetComponent<RectTransform>().pivot = new Vector2(0.5f, 1f);inventoryBar.inventoryTextBoxGameobject.transform.position = new Vector3(transform.position.x, transform.position.y - 50f, transform.position.z);}}}public void OnPointerExit(PointerEventData eventData){DestroyInventoryTextBox();}private void DestroyInventoryTextBox(){if (inventoryBar.inventoryTextBoxGameobject != null) {Destroy(inventoryBar.inventoryTextBoxGameobject);}}public void OnPointerClick(PointerEventData eventData){// if left clickif (eventData.button == PointerEventData.InputButton.Left){// if inventory slot currently selected then deselectif (isSelected == true){ClearSelectedItem();}else  // 未被选中且有东西则显示选中的效果{if(itemQuantity > 0){SetSelectedItem();}}}}/// <summary>/// Set this inventory slot item to be selected/// </summary>private void SetSelectedItem(){// Clear currently highlighted itemsinventoryBar.ClearHighlightOnInventorySlots();// Highlight item on inventory barisSelected = true;// Set highlighted inventory slotsinventoryBar.SetHighlightedInventorySlots();// Set item selected in inventoryInventoryManager.Instance.SetSelectedInventoryItem(InventoryLocation.player, itemDetails.itemCode);}private void ClearSelectedItem(){// Clear currently highlighted iteminventoryBar.ClearHighlightOnInventorySlots();isSelected = false;// set no item selected in inventoryInventoryManager.Instance.ClearSelectedInventoryItem(InventoryLocation.player);}
}

运行程序效果如下：
