# CHANGED_REGION

*LSL constant*

```lsl
integer CHANGED_REGION = 0x100;
```

Constant groups: [ChangeType](/constants/groups/ChangeType/)

The object has changed region by crossing a region boundary (or by teleporting, if attached). This event only occurs in the root prim of a linkset. This event does not occur in child prims of objects when they cross a region boundary.

## Examples

<summary>Example 1</summary>

```lsl
default
{
    changed(integer change)
    {
        if (change & CHANGED_REGION) //note that it's & and not &&... it's bitwise!
        {
            llOwnerSay("The region the object is in has changed.");
        }
    }
}
```
