Unity3D仿星露谷物语开发44之收集农作物

1、目标

在土地中挖掘后，洒下种子后逐渐成长，然后使用篮子收集成熟后的农作物，工具栏中也会相应地增加该农作物。

2、修改CropStandard的参数

Assets -> Prefabs -> Crop下的CropStandard，修改其Box Collider 2D的Size(Y)值为0.5。

3、修改GridCursor.cs脚本

添加如下代码：

[SerializeField] private SO_CropDetailsList so_CropDetailsList = null;

在IsCursorValidForTool函数中添加case ItemType.Collecting_tool代码：

private bool IsCursorValidForTool(GridPropertyDetails gridPropertyDetails, ItemDetails itemDetails)
{// Switch on toolswitch (itemDetails.itemType){case ItemType.Hoeing_tool:if (gridPropertyDetails.isDiggable == true && gridPropertyDetails.daysSinceDug == -1){#region Need to get any items at location so we can check if they are reapable// Get world position for cursorVector3 cursorWorldPosition = new Vector3(GetWorldPositionForCursor().x + 0.5f, GetWorldPositionForCursor().y + 0.5f, 0f);// Get list of items at cursor locationList<Item> itemList = new List<Item>();HelperMethods.GetComponentsAtBoxLocation<Item>(out itemList, cursorWorldPosition, Settings.cursorSize, 0f);#endregion// Loop through items found to see if any are reapable type - we are not goint to let the player dig where there are reapable scenary itemsbool foundReapable = false;foreach(Item item in itemList){if(InventoryManager.Instance.GetItemDetails(item.ItemCode).itemType == ItemType.Reapable_scenary){foundReapable = true;break;}}if (foundReapable){return false;}else{return true;}}else{return false;}case ItemType.Watering_tool:if(gridPropertyDetails.daysSinceDug > -1 && gridPropertyDetails.daysSinceWatered == -1){return true;}else{return false;}case ItemType.Collecting_tool:// Check if item can be harvested with item selected, check item is fully grown// Check if seed plantedif(gridPropertyDetails.seedItemCode != -1){// Get crop details for seed CropDetails cropDetails = so_CropDetailsList.GetCropDetails(gridPropertyDetails.seedItemCode);// if crop details foundif(cropDetails != null){// Check if crop fully grownif(gridPropertyDetails.growthDays >= cropDetails.totalGrowthDays){// Check if crop can be harvested with tool selectedif (cropDetails.CanUseToolToHarvestCrop(itemDetails.itemCode)){return true;}else{return false;}}else{return false;}}}return false;default:return false;}}

4、配置UIPanel的信息

Hierarchy -> PersistentScene -> UI -> MainGameUICanvas -> UICanvasGroup -> UIPanel，

配置SO_CropDetailsList的信息：

5、测试光标效果

种植完防风草，然后等待它们成长。

使用basket工具，发现只有成熟的防风草才会显示绿色光标，否则显示红色光标。

6、修改GridPropertiesManager.cs脚本

添加如下代码：

 /// <summary>/// Returns the Crop object at the gridX, gridY position or null if no crop was found/// </summary>/// <param name="gridPropertyDetails"></param>/// <returns></returns>public Crop GetCropObjectAtGridLocation(GridPropertyDetails gridPropertyDetails){Vector3 worldPosition = grid.GetCellCenterWorld(new Vector3Int(gridPropertyDetails.gridX, gridPropertyDetails.gridY, 0));Collider2D[] collider2DArray = Physics2D.OverlapPointAll(worldPosition);// Loop through colliders to get crop game objectCrop crop = null;for(int i = 0; i < collider2DArray.Length; i++){crop = collider2DArray[i].gameObject.GetComponentInParent<Crop>();if (crop != null && crop.cropGridPosition == new Vector2Int(gridPropertyDetails.gridX, gridPropertyDetails.gridY))break;crop = collider2DArray[i].gameObject.GetComponentInChildren<Crop>();if(crop != null && crop.cropGridPosition == new Vector2Int(gridPropertyDetails.gridX, gridPropertyDetails.gridY))break;}return crop;}/// <summary>
/// Returns Crop Details for the provided seedItemCode
/// </summary>
/// <param name="seedItemCode"></param>
/// <returns></returns>
public CropDetails GetCropDetails(int seedItemCode)
{return so_CropDetailList.GetCropDetails(seedItemCode);
}

7、修改Settings.cs脚本

添加如下代码：

    public static float pickAnimationPause = 1f;public static float afterPickAnimationPause = 0.2f;

8、修改Player.cs脚本

添加两个属性

    private WaitForSeconds afterPickAnimationPause;private WaitForSeconds pickAnimationPause;

在Start函数中增加如下代码：

pickAnimationPause = new WaitForSeconds(Settings.pickAnimationPause);
afterPickAnimationPause = new WaitForSeconds(Settings.afterPickAnimationPause);

在ProcessPlayerClickInput函数中增加如下代码：

case ItemType.Collecting_tool:

在ProcessPlayerClickInputTool函数中添加如下代码：

case ItemType.Collecting_tool:if (gridCursor.CursorPositionIsValid){CollectInPlayerDirection(gridPropertyDetails, itemDetails, playerDirection);}break;

添加CollectInPlayerDirection函数代码如下：

private void CollectInPlayerDirection(GridPropertyDetails gridPropertyDetails, ItemDetails equippedItemDetails, Vector3Int playerDirection)
{StartCoroutine(CollectInPlayerDirectionRoutine(gridPropertyDetails, equippedItemDetails, playerDirection));
}

添加CollectInPlayerDirectionRoutine函数代码如下：

private IEnumerator CollectInPlayerDirectionRoutine(GridPropertyDetails gridPropertyDetails, ItemDetails equippedItemDetails, Vector3Int playerDirection)
{PlayerInputIsDisabled = true;playerToolUseDisabled = true;ProcessCropWithEquippedItemInPlayerDirection(playerDirection, equippedItemDetails, gridPropertyDetails);yield return pickAnimationPause; // 执行完ProcessCropWithEquippedItemInPlayerDirection的时间// After animation pauseyield return afterPickAnimationPause;PlayerInputIsDisabled = false;playerToolUseDisabled = false;
}

添加ProcessCropWithEquippedItemInPlayerDirection函数代码如下：

/// <summary>/// Method processes crop with equipped item in player direction/// </summary>/// <param name="playerDirection"></param>/// <param name="equippedItemDetails"></param>/// <param name="gridPropertyDetails"></param>private void ProcessCropWithEquippedItemInPlayerDirection(Vector3Int playerDirection, ItemDetails equippedItemDetails, GridPropertyDetails gridPropertyDetails){switch (equippedItemDetails.itemType){case ItemType.Collecting_tool:if(playerDirection == Vector3Int.right){isPickingRight = true;}else if(playerDirection == Vector3Int.left){isPickingLeft = true;}else if(playerDirection == Vector3Int.up){isPickingUp = true;}else if(playerDirection == Vector3Int.down){isPickingDown = true;}break;case ItemType.none:break;}// Get crop at cursor grid locationCrop crop = GridPropertiesManager.Instance.GetCropObjectAtGridLocation(gridPropertyDetails);// Execute Process Tool Action For cropif(crop != null){switch (equippedItemDetails.itemType){case ItemType.Collecting_tool:crop.ProcessToolAction(equippedItemDetails);break;}}}

此时，Player.cs完整的代码如下：

}

9、修改Crop.cs脚本

完整代码如下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Crop : MonoBehaviour
{[HideInInspector]public Vector2Int cropGridPosition;private int harvestActionCount = 0;public void ProcessToolAction(ItemDetails equippedItemDetails){// Get grid property detailsGridPropertyDetails gridPropertyDetails = GridPropertiesManager.Instance.GetGridPropertyDetails(cropGridPosition.x, cropGridPosition.y);if (gridPropertyDetails == null)return;// Get seed item detailsItemDetails seedItemDetails = InventoryManager.Instance.GetItemDetails(gridPropertyDetails.seedItemCode);if(seedItemDetails == null) return;// Get crop detailsCropDetails cropDetails = GridPropertiesManager.Instance.GetCropDetails(seedItemDetails.itemCode);if (cropDetails == null) return;// Get required harvest actions for tool（收获此农作物所需的操作次数）int requiredHarvestActions = cropDetails.RequiredHarvestActionsForTool(equippedItemDetails.itemCode);if (requiredHarvestActions == -1) return;// Increment harvest action countharvestActionCount++;// Check if required harvest actions madeif (harvestActionCount >= requiredHarvestActions)HarvestCrop(cropDetails, gridPropertyDetails);}private void HarvestCrop(CropDetails cropDetails, GridPropertyDetails gridPropertyDetails){// Delete crop from grid propertiesgridPropertyDetails.seedItemCode = -1;gridPropertyDetails.growthDays = -1;gridPropertyDetails.daysSinceLastHarvest = -1;gridPropertyDetails.daysSinceWatered = -1;GridPropertiesManager.Instance.SetGridPropertyDetails(gridPropertyDetails.gridX, gridPropertyDetails.gridY, gridPropertyDetails);HarvestActions(cropDetails, gridPropertyDetails);}private void HarvestActions(CropDetails cropDetails, GridPropertyDetails gridPropertyDetails){SpawnHarvestedItems(cropDetails);Destroy(gameObject);  // destory当前Crop类所挂载的实例}private void SpawnHarvestedItems(CropDetails cropDetails){// Spawn the item(s) to be producedfor(int i = 0; i < cropDetails.cropProducedItemCode.Length; i++){int cropsToProduce;// Calculate how many crops to produceif (cropDetails.cropProducedMinQuantity[i] == cropDetails.cropProducedMaxQuantity[i] ||cropDetails.cropProducedMaxQuantity[i] < cropDetails.cropProducedMinQuantity[i]){cropsToProduce = cropDetails.cropProducedMinQuantity[i];}else{cropsToProduce = Random.Range(cropDetails.cropProducedMinQuantity[i], cropDetails.cropProducedMaxQuantity[i] + 1);}for(int j = 0; j < cropsToProduce; j++){Vector3 spawnPosition;if (cropDetails.spawnCropProducedAtPlayerPosition){// Add item to the players inventoryInventoryManager.Instance.AddItem(InventoryLocation.player, cropDetails.cropProducedItemCode[i]);}else{// Random positionspawnPosition = new Vector3(transform.position.x + Random.Range(-1f, 1f), transform.position.y + Random.Range(-1f, 1f), 0f);SceneItemsManager.Instance.InstantiateSceneItem(cropDetails.cropProducedItemCode[i], spawnPosition);}}}}}

10、修改InventoryManager.cs脚本

添加如下代码：

public void AddItem(InventoryLocation inventoryLocation, int itemCode)
{List<InventoryItem> inventoryList = inventoryLists[(int)inventoryLocation];// Check if inventory already contains the itemint itemPosition = FindItemInInventory(inventoryLocation, itemCode);if(itemPosition != -1){AddItemPosition(inventoryList, itemCode, itemPosition);}else{AddItemPosition(inventoryList, itemCode);}// Send event that inventory has been updatedEventHandler.CallInventoryUpdatedEvent(inventoryLocation, inventoryLists[(int)inventoryLocation]);
}

11、修改SceneItemsManager.cs脚本

增加如下代码：

private void InstantiateSceneItem(int ItemCode, Vector3 position)
{GameObject itemGameObject = Instantiate(itemPrefab, position, Quaternion.identity, parentItem);Item item = itemGameObject.GetComponent<Item>();item.ItemCode = ItemCode;
}

12、修改SO_CropDetailsList的配置

修改10006的配置：

勾选spawnCropProducedAtPlayerPosition，使得收获的农作物在Inventory中展示。

13、运行游戏

防风草种子成熟后，点击篮子进行采摘，则防风草会出现在最后一个Slot中。

如果Slot之前已经有防风草了，则会直接往上加数量。
