# AddCollisionFrom

### Introduction

The AddCollisionFrom method can be used to add AxisAlignedRectangle instances to the TileShapeCollection from a tile map (MapDrawableBatch).

### Code Examples

AddCollisionFrom provides lots of flexibility for adding collision. The simplest form is to add collision from a tile by the tile name. The following code adds collision for all tiles named "CollisionTile":

```lang:c#
SolidCollisions.AddCollisionFrom(CurrentTileMap,"CollisionTile");
```

Using names is simple, but can also be restrictive. For example, we can check a tile to see if any of its properties are named "IsSpikes":

```lang:c#
SpikeCollisions.AddCollisionFrom(CurrentTileMap,(list => 
                 list.Any(item => item.Name == "IsSpike" && item.Value == "true")));
```

Note that if adding collision based on tile property names alone (not the value), see the AddCollisionFromTilesWithProperty method: [http://flatredball.com/documentation/tools/tiled-plugin/glue-gluevault-component-pages-tile-graphics-plugin-tileshapecollection/addcollisionfromtileswithproperty/](/flatredball/tiled-plugin/glue-gluevault-component-pages-tile-graphics-plugin-tileshapecollection/addcollisionfromtileswithproperty.md)

## 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/glue-gluevault-component-pages-tile-graphics-plugin-tileshapecollection/addcollisionfrom.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.
