# RemoveQuads

### Introduction

RemoveQuads can be used to remove quads from the MapDrawableBatch by index. This method is useful in situations where you want to remove tiles from the MapDrawableBatch at runtime, such as when creating Entities from the contents of a tile map.

### Code Example

The following shows how to remove the first three tiles from the MapDrawableBatch:

```
List<int> toRemove = new List<int>();
toRemove.Add(0);
toRemove.Add(1);
toRemove.Add(2);
// assuming MyLevel is a valid LayeredTileMap:
MyLevel.MapLayers[0].RemoveQuads(toRemove);
```

For more information on LayeredTileMap, see the [LayeredTileMap page](https://github.com/flatredball/FlatRedBallDocs/blob/main/frb/docs/index.php).

### Code Example - Removing Quads With the Cursor

Often the internal quad ordering is unknown. Therefore, the MapDrawableBatch class provides a GetQuadIndex method to convert world X and Y to an index. If no tile is located at the index, a value of null is returned. The following code could be used to remove quads when the user clicks a mouse:

```
var cursor = GuiManager.Cursor;
if(cursor.PrimaryPush)
{
  var quadIndex = MapLayer.GetQuadIndex(cursor.WorldX, cursor.WorldY);

  if(quadIndex != null)
  {
    // RemoveQuads takes an IEnumerable so that multiple quads can be removed at once
    List quads = new List(){quadIndex.Value};
    MapLayer.RemoveQuads(quads);
  }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flatredball.com/flatredball/tiled-plugin/flatredball-tilegraphics-mapdrawablebatch/removequads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
