Question

我想将Tilemap中的所有单元格都放入一个数组，我尝试过：

Vector3Int[] Example = Examplemap.cellBounds

但这没用。请帮助我

枚举Tilemap.cellBounds.allPositionsWithin，在每个循环中应返回BoundsInt。使用HasTile检查Tilemap中是否有该位置的图块。如果该位置有一块图块，请使用Tilemap.CellToWorld将位置隐蔽到世界中，然后将其添加到List中。

List<Vector3> GetCellsFromTilemap(Tilemap tilemap)
{
    List<Vector3> worldPosCells = new List<Vector3>();
    foreach (var boundInt in tilemap.cellBounds.allPositionsWithin)
    {
        //Get the local position of the cell
        Vector3Int relativePos = new Vector3Int(boundInt.x, boundInt.y, boundInt.z);
        //Add it to the List if the local pos exist in the Tile map
        if (tilemap.HasTile(relativePos))
        {
            //Convert to world space
            Vector3 worldPos = tilemap.CellToWorld(relativePos);
            worldPosCells.Add(worldPos);
        }
    }
    return worldPosCells;
}

要使用：

Tilemap Examplemap = ...;
List<Vector3> cells = GetCellsFromTilemap(Examplemap);

如果您希望将单元格位置返回本地空间，请用tilemap.CellToWorld(relativePos)替换tilemap.CellToLocal(relativePos)。

List<Vector3> GetCellsFromTilemap(Tilemap tilemap)
{
    List<Vector3> worldPosCells = new List<Vector3>();
    foreach (var boundInt in tilemap.cellBounds.allPositionsWithin)
    {
        //Get the local position of the cell
        Vector3Int relativePos = new Vector3Int(boundInt.x, boundInt.y, boundInt.z);
        //Add it to the List if the local pos exist in the Tile map
        if (tilemap.HasTile(relativePos))
        {
            //Convert to world space
            Vector3 localPos = tilemap.CellToLocal(relativePos);
            worldPosCells.Add(localPos);
        }
    }
    return worldPosCells;
}

最后，如果只希望Vector2Ints不进行转换，则只需将循环中的数据直接添加到List：

List<Vector3Int> GetCellsFromTilemap(Tilemap tilemap)
{
    List<Vector3Int> cells = new List<Vector3Int>();
    foreach (var boundInt in tilemap.cellBounds.allPositionsWithin)
    {
        //Get the local position of the cell
        Vector3Int relativePos = new Vector3Int(boundInt.x, boundInt.y, boundInt.z);
        //Add it to the List if the local pos exist in the Tile map
        if (tilemap.HasTile(relativePos))
            cells.Add(relativePos);
    }
    return cells;
}

我可以从Boundsint获取所有Vector2Ints吗？ C＃Unity
