Unity3D仿星露谷物语开发36之锄地动画2

news 来源：原创 2025/4/21 6:42:09

1、目标

当角色锄地之后，地面会显示开垦后的样貌。

2、思路

上一篇中，虽然角色dig了hoe，同时grid属性也改变了，但是没有任何可视化的反馈。我们现在将添加新的功能，动态地将"dug ground"瓷砖添加到"GroundDecoration1"的tilemap上。

将使用如下的tileset进行绘制。

为了设置正确的dug ground tile，我们需要检查下周边的tiles是否被dug，此时存在16种组合方式。

第1、2种组合方式：

第3、4种组合方式：

第5、6种组合方式：

第7、8种组合方式：

第9、10种组合方式：

第11、12种组合方式：

第13、14种组合方式：

第15、16种组合方式：

连接周边grid的情况：

我们将增加"dug ground" tiles到GroundDecoration1 tilemaps。我们将标记GroundDecoration1和GroundDecoration2 tilemap层，以便可以快速定位到他们，这些标记放到Tag.cs脚本中。

修改GridPropertiesManager.cs脚本如下：

修改Player.cs脚本

3、修改Tag.cs脚本

public static class Tags
{public const string BoundsConfiner = "BoundsConfiner";public const string ItemsParentTransform = "ItemsParentTransform";public const string GroundDecoration1 = "GroundDecoration1";public const string GroundDecoration2 = "GroundDecoration2";
}

添加了下面的2个静态变量。

4、修改GridPropertiesManager.cs脚本

// 修改public为private
private Grid grid;// 添加变量
private Tilemap groundDecoration1;
private Tilemap groundDecoration2;
[SerializeField] private Tile[] dugGround = null;// 添加函数private void ClearDisplayGroundDecorations(){// Remove ground decorationsgroundDecoration1.ClearAllTiles();groundDecoration2.ClearAllTiles();}private void ClearDisplayGridPropertyDetails(){ClearDisplayGroundDecorations();}private void ConnectDugGround(GridPropertyDetails gridPropertyDetails)

{GridPropertyDetails gridPropertyDetails = GetGridPropertyDetails(xGrid, yGrid);if(gridPropertyDetails == null){return false;}else if(gridPropertyDetails.daysSinceDug > -1){return true;}else{return false;}
}private void DisplayGridPropertyDetails()
{// Loop throught all grid itemsforeach(KeyValuePair<string, GridPropertyDetails> item in gridPropertyDictionary){GridPropertyDetails gridPropertyDetails = item.Value;DisplayDugGround(gridPropertyDetails);}
}// 优化ISaveableRestoreScene函数public void ISaveableRestoreScene(string sceneName){// Get sceneSave for scene - it exists since we created it in initialiseif(GameObjectSave.sceneData.TryGetValue(sceneName, out SceneSave sceneSave)){// get grid property details dictionary - it exists since we created it in initialiseif(sceneSave.gridPropertyDetailsDictionary != null){gridPropertyDictionary = sceneSave.gridPropertyDetailsDictionary;}// If grid properties existif(gridPropertyDictionary.Count > 0){// grid property details found for the current scene destroy existing ground decorationClearDisplayGridPropertyDetails();// Instantiate grid property details for current sceneDisplayGridPropertyDetails();}}}// 优化AfterSceneLoaded函数

5、修改Player.cs脚本

在HoeGroundAtCursorRoutine函数中添加如下代码：

6、设置绘图

（1）创建新的Palette

Create New Palette，并且命名为DugGround，保存到Assets -> Tilemap -> Tile Palettes下。

（2）创建新的Tiles

在Assets -> Sprites -> Sprite Textures -> Tile Sprites 下找到DugGround.

将DugGround拖到右边的Palette中，弹出的目录选择Assets -> Tilemap -> Tiles，创建新的目录Dug Ground，保存到该目录下。

左边灰色为Dug后的grid图案，右边银色为Water之后的grid图案。

7、配置Tile信息

点击Assets -> Tilemap -> Tiles -> Dug Ground，然后点击Open。

点击PersistentScene -> GridPropertiesManager，将Dug Ground中灰色的图片拖入到Dug Ground的List中。

8、添加Tag

点击GridPropertiesManager，点击Add Tag。

添加GroundDecoration1和GroundDecoration2两个Tag。

然后依次给Scene1/Scene2/Scene3场景Tilemap Grid下的GroundDecoration1和GroundDecoration2对象设置GroundDecoration1和GroundDecoration2两个Tag。

设置Prefabs -> Maps -> Tilemap Grid下的GroundDecoration1和GroundDecoration2对象设置GroundDecoration1和GroundDecoration2两个Tag。

9、运行游戏
