Unity3D仿星露谷物语开发40之割草动画

1、目标

当Player选择Scythe后，鼠标悬浮在草上，会显示绿色光标。鼠标左击，会触发割草的动画。

2、优化Settings.cs脚本

添加以下两行代码：

// Reaping（收割）
public const int maxCollidersToTestPerReapSwing = 15; // 每次收割检测的最多的碰撞体数量
public const int maxTargetComponentsToDestroyPerReapSwing = 2; // 每次收割销毁的最多的组件数量

3、优化Player.cs脚本

1）添加一个变量：

2）Awake方法中添加新的定义

3）Start方法中添加新的定义

4）PlayerClickInput方法中增加一个if条件

5）ProcessPlayerClickInput方法增加一个case条件

6）ProcessPlayerClickInputTool方法增加case条件

7）添加判断角色方向的方法：

计算的方式如下：

private Vector3Int GetPlayerDirection(Vector3 cursorPosition, Vector3 playerPosition)
{if(cursorPosition.x > playerPosition.x&&cursorPosition.y < (playerPosition.y + cursor.ItemUseRadius / 2f)&&cursorPosition.y > (playerPosition.y - cursor.ItemUseRadius / 2f)){return Vector3Int.right;}else if(cursorPosition.x < playerPosition.x&&cursorPosition.y < (playerPosition.y + cursor.ItemUseRadius / 2f)&&cursorPosition.y > (playerPosition.y - cursor.ItemUseRadius / 2f)){return Vector3Int.left;}else if(cursorPosition.y > playerPosition.y){return Vector3Int.up;}else{return Vector3Int.down;}
}

8）添加ReapInPlayerDirectionAtCursor方法

private void ReapInPlayerDirectionAtCursor(ItemDetails itemDetails, Vector3Int playerDirection)
{StartCoroutine(ReapInPlayerDirectionAtCursorRoutine(itemDetails, playerDirection));
}

9）添加ReapInPlayerDirectionAtCursorRoutine方法

private IEnumerator ReapInPlayerDirectionAtCursorRoutine(ItemDetails itemDetails, Vector3Int playerDirection)
{PlayerInputIsDisabled = true;playerToolUseDisabled = true;// Set tool animation to scythe in override animationtoolCharacterAttribute.partVariantType = PartVariantType.scythe;characterAttributeCustomisationList.Clear();characterAttributeCustomisationList.Add(toolCharacterAttribute);animationOverrides.ApplyCharacterCustomisationParameters(characterAttributeCustomisationList);// Reap in player directionUseToolInPlayerDirection(itemDetails, playerDirection);yield return useToolAnimationPause;PlayerInputIsDisabled = false;playerToolUseDisabled = false;
}

10）添加UseToolInPlayerDirection方法

private void UseToolInPlayerDirection(ItemDetails equippedItemDetails, Vector3Int playerDirection)
{if (Input.GetMouseButton(0)){switch (equippedItemDetails.itemType){case ItemType.Reaping_tool:if(playerDirection == Vector3Int.right){isSwingToolRight = true;}else if(playerDirection == Vector3Int.left){isSwingToolLeft = true;}else if(playerDirection == Vector3Int.up){isSwingToolUp = true;}else if(playerDirection == Vector3Int.down){isSwingToolDown = true;}break;}// Define centre point of square which will be used for collision testing，检测碰撞的中心点位置Vector2 point = new Vector2(GetPlayerCentrePosition().x + playerDirection.x * (equippedItemDetails.itemUseRadius / 2f),GetPlayerCentrePosition().y + playerDirection.y * (equippedItemDetails.itemUseRadius / 2f));// Define size of the square which will be used for collision testingVector2 size = new Vector2(equippedItemDetails.itemUseRadius, equippedItemDetails.itemUseRadius);// Get Item components with 2D collider located in the square at the centre point defined (2d colliders tested limited to maxCollidersToTestPerReapSwing)Item[] itemArray = HelperMethods.GetComponentsAtBoxLocationNonAlloc<Item>(Settings.maxCollidersToTestPerReapSwing, point, size, 0f);int reapableItemCount = 0;// Loop through all items retrievedfor(int i = itemArray.Length - 1; i >= 0; i--){if(itemArray[i] != null){// Destory item game object if reapableif (InventoryManager.Instance.GetItemDetails(itemArray[i].ItemCode).itemType == ItemType.Reapable_scenary){// Effect positionVector3 effectPosition = new Vector3(itemArray[i].transform.position.x, itemArray[i].transform.position.y + Settings.gridCellSize / 2f,itemArray[i].transform.position.z);Destroy(itemArray[i].gameObject);reapableItemCount++;if (reapableItemCount >= Settings.maxTargetComponentsToDestroyPerReapSwing)break;}}}}
}

11）添加onEnable和onDisable方法

private void OnDisable()
{EventHandler.BeforeSceneUnloadFadeOutEvent -= DisablePlayerInputAndResetMovement;EventHandler.AfterSceneLoadFadeInEvent -= EnablePlayerInput;
}private void OnEnable()
{EventHandler.BeforeSceneUnloadFadeOutEvent += DisablePlayerInputAndResetMovement;EventHandler.AfterSceneLoadFadeInEvent += EnablePlayerInput;
}
