%roomGetRadiusItems()

    This function returns an array of item pointers for items that are found
    within the requested @radius of the @source. The @source may be the ID of
    a room or a pointer to a room, mobile, or item. Flags may be set to
    determine specific rules for room traversal. For instance, by default the
    room of origin is NOT included but this can be changed by setting the
    "includeOrigin" flag. Following is a list of currently supported flags:

        includeOrigin       - include the origin room in the results
        allowNoDirection    - traverse exits flagged as noDirection
        allowSecret         - traverse exits flagged as secret
        allowClosed         - traverse closed doors
        allowDeathtrap      - include deathtrap rooms

    Example:

        //
        // Create a cyclone of debris.
        //

        @flags = %array( includeOrigin )
        @items = %roomGetRadiusItems( @caster, 5, "includeOrigin" )

        foreach( @items as @item )
        {
            %move( @item, %where( @caster ) )
        }
        endforeach

        %echo( "A cyclone manifests and takes shape as it pulls in "
        \      "nearby debris." )

        //
        // Smack the players around with the debris similar to what we do
        // with whirlwind.
        //
