CoreFriendCollection

Contains a set of results from CoreSocial.GetFriends(). Depending on how many friends a player has, results may be separated into multiple pages. The .hasMoreResults property may be checked to determine whether more friends are available. Those results may be retrieved using the :GetMoreResults() function.

Properties

Property Name	Return Type	Description	Tags
`hasMoreResults`	`boolean`	Returns `true` if there are more friends available to be requested.	Read-Only

Functions

Function Name	Return Type	Description	Tags
`GetResults()`	`Array`<`CoreFriendCollectionEntry`>	Returns the list of friends contained in this set of results. This may return an empty table for players who have no friends.	None
`GetMoreResults()`	`CoreFriendCollection`	Requests the next set of results for this list of friends and returns a new collection containing those results. Returns `nil` if the `hasMoreResults` property is `false`. This function may yield until a result is available, and may raise an error if an error occurs retrieving the information.	None

Examples

Example using:

`hasMoreResults`

`GetResults`

`GetMoreResults`

A player's list of friends is split into multiple pages of data. In this example, we implement a set of useful functions, not only for loading the pages, but for moving forward and backwards through the collection.

local friendCollection = nil

local pages = {}
local pageIndex = 0

function Setup(player)
    friendCollection = CoreSocial.GetFriends(player)
    local firstPage = friendCollection:GetResults()
    pages = { firstPage }
    pageIndex = 1
end

function GetCurrentPage()
    return pages[pageIndex]
end

function HasPreviousPage()
    return pageIndex > 1
end

function HasNextPage()
    return pageIndex < #pages or friendCollection.hasMoreResults
end

function PreviousPage()
    pageIndex = pageIndex - 1
    if pageIndex < 1 then
        pageIndex = 1
    end
    return GetCurrentPage()
end

function NextPage()
    pageIndex = pageIndex + 1
    if pageIndex > #pages then
        if friendCollection.hasMoreResults then
            friendCollection = friendCollection:GetMoreResults()
            local newPage = friendCollection:GetResults()
            table.insert(pages, newPage)
        else
            pageIndex = #pages
        end
    end
    return GetCurrentPage()
end

function PrintPage(pageData)
    for _,entry in ipairs(pageData) do
        print(entry.name .. ":" .. entry.id)
    end
end
