【Unity Tile自定义及转json工具】

最近新开始了一个新游戏，2D像素养成经营。地图是Tilemap制作的，需求为更换场景中建筑的样式。我这里是直接使用了Tilemap.SetTile来进行更换

自定义瓦片

Unity 自带的瓦片没有任何属性，肯定是不够用的。所以需要自定义瓦片。自定义很简单，只需要继承TileBase类就可以了，这里自定义了一个枚举，当前的瓦片是哪个部位。

更换场景中的Tile

在用Tilemap更换Tile需要一个vector3int 的位置，这里需要遍历整个Tilemap里面寻找自定义的Tile再去更改，如果每次更新都需要遍历一遍，很蠢。所以这里就提前给当前Tilemap所有自定义的Tile位置信息存储起来

更换Tile，这里的AnimalRoomTileData 是读取json获得

工具提前存储位置

遍历Tilemap中所有自定义Tile 将位置信息储存为Json，直接贴代码了

public class AnimalRoom2Json :EditorWindow
{
    private Tilemap currentAnimalRoomMap;
    private Vector2 scrollPosition;
    [MenuItem( "Tool/AnimalRoom2Json" )]
    public static void ShowWindow( )
    {
        AnimalRoom2Json window = GetWindow<AnimalRoom2Json>( );
        window.titleContent = new GUIContent( "笼舍地图转为json" );
        window.minSize = new Vector2( 540 , 520 );
        window.maxSize = new Vector2( 540 , 520 );
        window.Focus( );
    }


    private void OnGUI( )
    {
        currentAnimalRoomMap = (Tilemap)EditorGUI.ObjectField( new Rect( 20 , 20 , 500 , 20 ) , "笼舍TileMap:" , currentAnimalRoomMap , typeof( Tilemap ) );
        if( null == currentAnimalRoomMap )
        {
            return;
        }

        BoundsInt bounds = currentAnimalRoomMap.cellBounds;
        TileBase[] allTiles = currentAnimalRoomMap.GetTilesBlock( bounds );
        List<AnimalRoomTileData> tempList = new List<AnimalRoomTileData>( );
        for( int x = bounds.xMin ; x < bounds.xMax ; x++ )
        {
            for( int y = bounds.yMin ; y < bounds.yMax ; y++ )
            {
                AnimalRoomTile animalRoomTile = currentAnimalRoomMap.GetTile<AnimalRoomTile>( new Vector3Int( x , y ) );
                if( null == animalRoomTile )
                {
                    continue;
                }
                AnimalRoomTileData animalRoomTileData = new AnimalRoomTileData( x , y , (int)animalRoomTile.part );
                tempList.Add( animalRoomTileData );
            }
        }

        scrollPosition = GUI.BeginScrollView( new Rect( 20 , 60 , 500 , 380 ) , scrollPosition , new Rect( 20 , 60 , 400 , tempList.Count * 20 + 20 ) );
        {
            int height = 40;
            int i = 0;
            foreach( var data in tempList )
            {
                height += 20;
                i += 1;
                EditorGUI.LabelField( new Rect( 20 , height , 50 , 20 ) , "位置： X: " + data.x );
                EditorGUI.LabelField( new Rect( 150 , height , 50 , 20 ) , "Y：" + data.y );
                EditorGUI.LabelField( new Rect( 280 , height , 150 , 20 ) , "Part：" + ( (AnimalRoomTile.RoomPart)data.part ).ToString( ) );
            }
        }
        GUI.EndScrollView( );

        if( GUI.Button( new Rect( 20 , 460 , 500 , 50 ) , "转为Json" ) )
        {
            string message = AnimalRoomTileDataProxy.ToJson( new AnimalRoomTileDataProxy( tempList ) );
            string defaultName = "AnimalRoom" + currentAnimalRoomMap.GetComponent<AnimalRoomBuild>( ).id;
            string path = EditorUtility.SaveFilePanel( "储存" , Application.dataPath + "Asset/Resources/Json" , defaultName , "txt" );

            if( string.IsNullOrEmpty( path ) )
            {
                return;
            }

            path = Path.GetFullPath( path );
            File.WriteAllText( path , message );
            AssetDatabase.Refresh( );
            EditorUtility.DisplayDialog( "储存成功" , path , "确定" );
        }
    }
