1、目标

当从道具栏中拖出一个道具到地面的时候，光标区域会显示是否可放置物体的可视化显示。绿色表示可以放置物体，红色表示不可以放置物体。

2、优化InventoryManager脚本

添加2个方法：

    /// <summary>/// Returns the itemDetails（from the SO_ItemList）for the currently selected item in the inventoryLocation,/// or null if an item isn't selected/// </summary>/// <param name="inventoryLocation"></param>/// <returns></returns>public ItemDetails GetSelectedInventoryItemDetails(InventoryLocation inventoryLocation){int itemCode = GetSelectedInventoryItem(inventoryLocation);if(itemCode == -1){return null;}else{return GetItemDetails(itemCode);}}/// <summary>/// Set the selected inventory item for inventoryLocation to itemCode/// </summary>/// <param name="inventoryLocation"></param>/// <param name="itemCode"></param>public void SetSelectedInventoryItem(InventoryLocation inventoryLocation, int itemCode){selectedInventoryItem[(int)inventoryLocation] = itemCode;  }

完整的代码如下：

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;

}

3、创建GridCursor脚本

在Assets -> Scripts -> UI 下创建脚本命名为GridCursor。

完整代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class GridCursor : MonoBehaviour
{private Canvas canvas; // 存储白色画布，UI光标位于其中private Grid grid;  // tilemap地图private Camera mainCamera; // 对主相机的引用[SerializeField] private Image cursorImage = null;[SerializeField] private RectTransform cursorRectTransform = null;  // 光标对象的引用[SerializeField] private Sprite greenCursorSprite = null;[SerializeField] private Sprite redCursorSprite = null;private bool _cursorPositionIsValid = false;public bool CursorPositionIsValid { get => _cursorPositionIsValid; set => _cursorPositionIsValid = value; }private int _itemUseGridRadius = 0;public int ItemUseGridRadius { get => _itemUseGridRadius; set => _itemUseGridRadius = value; }private ItemType _selectedItemType;public ItemType SelectedItemType { get => _selectedItemType; set => _selectedItemType = value; }private bool _cursorIsEnabled = false;public bool CursorIsEnabled { get => _cursorIsEnabled; set => _cursorIsEnabled = value; }private void OnDisable(){EventHandler.AfterSceneLoadEvent -= SceneLoaded;}private void OnEnable(){EventHandler.AfterSceneLoadEvent += SceneLoaded;}// Start is called before the first frame updatevoid Start(){mainCamera = Camera.main;canvas = GetComponentInParent<Canvas>();}// Update is called once per framevoid Update(){if (CursorIsEnabled){DisplayCursor();}}private Vector3Int DisplayCursor(){if (grid != null){   // 之所以需要Grid是因为某些定位是基于grid的// Get grid position for cursorVector3Int gridPosition = GetGridPositionForCursor();// Get grid position for playerVector3Int playerGridPosition = GetGridPositionForPlayer();// Set cursor sprite,基于gridPosition和playerGridPosition设置光标的有效性SetCursorValidity(gridPosition, playerGridPosition);// Get rect transform position for cursorcursorRectTransform.position = GetRectTransformPositionForCursor(gridPosition);return gridPosition;}else{return Vector3Int.zero;}}public Vector3Int GetGridPositionForCursor(){// z is how far the objects are in front of the camera - camera is at -10 so objects are(-)-10 in front = 10Vector3 worldPosition = mainCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, -mainCamera.transform.position.z));return grid.WorldToCell(worldPosition);}public Vector3Int GetGridPositionForPlayer(){return grid.WorldToCell(Player.Instance.transform.position);}public Vector2 GetRectTransformPositionForCursor(Vector3Int gridPosition){Vector3 gridWorldPosition = grid.CellToWorld(gridPosition);Vector2 gridScreenPosition = mainCamera.WorldToScreenPoint(gridWorldPosition);return RectTransformUtility.PixelAdjustPoint(gridScreenPosition, cursorRectTransform, canvas);}private void SceneLoaded(){grid = GameObject.FindObjectOfType<Grid>();}private void SetCursorValidity(Vector3Int cursorGridPosition, Vector3Int playerGridPosition){SetCursorToValid();// Check item use radius is validif(Mathf.Abs(cursorGridPosition.x -  playerGridPosition.x) > ItemUseGridRadius|| Mathf.Abs(cursorGridPosition.y - playerGridPosition.y) > ItemUseGridRadius){SetCursorToInvalid();return;}// Get selected item details ItemDetails itemDetails = InventoryManager.Instance.GetSelectedInventoryItemDetails(InventoryLocation.player);if(itemDetails == null){SetCursorToInvalid();return;}// Get grid property details at cursor positionGridPropertyDetails gridPropertyDetails = GridPropertiesManager.Instance.GetGridPropertyDetails(cursorGridPosition.x, cursorGridPosition.y);if(gridPropertyDetails != null){// Determine cursor validity based on inventory item selected and grid property detailsswitch (itemDetails.itemType){case ItemType.Seed:if (!IsCursorValidForSeed(gridPropertyDetails)){SetCursorToInvalid();return;}break;case ItemType.Commodity:if (!IsCursorValidForCommodity(gridPropertyDetails)){SetCursorToInvalid();return;}break;case ItemType.none:break;case ItemType.count:break;default:break;}}else{SetCursorToInvalid();return;}}private bool IsCursorValidForSeed(GridPropertyDetails gridPropertyDetails){return gridPropertyDetails.canDropItem;}private bool IsCursorValidForCommodity(GridPropertyDetails gridPropertyDetails){return gridPropertyDetails.canDropItem;}private void SetCursorToValid(){cursorImage.sprite = greenCursorSprite;CursorPositionIsValid = true;}private void SetCursorToInvalid(){cursorImage.sprite = redCursorSprite;CursorPositionIsValid = false;}/// <summary>/// DisableCursor is called in the UIInventorySlot.ClearCursors() method when an inventory slot item is no longer selected/// </summary>public void DisableCursor(){cursorImage.color = Color.clear;CursorIsEnabled = false;}/// <summary>/// EnableCursor is called in the UIInventorySlot.SetSelectedItem() method when an inventory slot item is selected and its itemUseGrid radius>0/// </summary>public void EnableCursor(){cursorImage.color = new Color(1f, 1f, 1f, 1f);CursorIsEnabled = true;}}

4、优化UIInventorySlot脚本

增加如下变量：

private GridCursor gridCursor;

在Start()中添加：

gridCursor = FindObjectOfType<GridCursor>();

添加如下方法：

private void ClearCursors()
{// Disable cursorgridCursor.DisableCursor();// Set item type to nonegridCursor.SelectedItemType = ItemType.none;
}

在SetSelectedItem方法中添加如下方法：

        // Set use radius for cursors gridCursor.ItemUseGridRadius = itemDetails.itemUseGridRadius;// If item requires a grid cursor then enable cursorif(itemDetails.itemUseGridRadius > 0){gridCursor.EnableCursor();}else{gridCursor.DisableCursor();}// Set item typegridCursor.SelectedItemType = itemDetails.itemType;

在ClearSelectedItem方法中添加：

ClearCursors();

在DropSelectedItemAtMousePosition方法中，删除如下3行代码：

替换为：

if (gridCursor.CursorPositionIsValid) {Vector3 worldPosition = mainCamera.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, -mainCamera.transform.position.z));
