Description
Fetch a specific leaderboard belonging to this Instant Game.
FBInstant.getLeaderboardAsync(name,callback)
Parameters
name: (string) The name of the leaderboard. Each leaderboard for an Instant Game must have its own distinct name.
callback: (function) A function that will be called with two arguments: Result with the matching leaderboard, rejecting if one is not found. An error code if the function failed.
Examples
Example
FBInstant.getLeaderboardAsync("my_aweome_leaderboard", function(result,error)
print("getLeaderboardAsync result:",result)
end)
<br/>
Example 2
FBInstant.getLeaderboardAsync("my_aweome_leaderboard", function(result,error)
print("name",result:getName()) -- should display 'my__awesome_leaderboard'
print("context id",result:getContextID()) -- eg 12345678 or null if not tied to a context
result:getEntryCountAsync( function (result,error) -- Fetches the total number of player entries in the leaderboard.
if result then
print("Count",result)
end
end)
--Update the player's score. If the player has an existing score, the old score will only be replaced if the new score is better than it.
-- NOTE: If the leaderboard is associated with a specific context, the game must be in that context to set a score for the player.
result:setScoreAsync(level,FBInstant.player.getName(),function(self,result,entry)
if result then
print("score ok",entry)
for key,val in pairs(entry.entry) do
print(key,val)
end
end
end)
-- Retrieves the leaderboard's entry for the current player, or null if the player has not set one yet.
result:getPlayerEntryAsync( function (self,result,entry)
if entry and entry.entry then -- important you check this as it may not exist...
for key,val in pairs(entry.entry) do
print(key,val)
if key=="player" then
for key2,val2 in pairs(val) do
print(" ",key2,val2)
end
end
end
end
end)
-- Retrieve a set of leaderboard entries, ordered by score ranking in the leaderboard.
-- parameter: count number The number of entries to attempt to fetch from the leaderboard. Defaults to 10 if not specified. Up to a maximum of 100 entries may be fetched per query.
-- parameter: offset number The offset from the top of the leaderboard that entries will be fetched from.
result:getEntriesAsync(10,0,function(self,result,entries)
print(self,result,entries)
for loop=1,#entries do
local e=entries[loop].entry
print("at entry",loop)
for key,val in pairs(e) do
print(key,val)
if key=="player" then
for key2,val2 in pairs(val) do
print(" ",key2,val2)
end
end
end
end
end)
-- Most useful of all:
-- Retrieve a set of connected player leaderboard entries, ordered by score ranking in the leaderboard.
-- parameter: count number The number of entries to attempt to fetch from the leaderboard. Defaults to 10 if not specified. Up to a maximum of 100 entries may be fetched per query.
-- parameter: offset number The offset from the top of the leaderboard that entries will be fetched from.
result:getConnectedPlayerEntriesAsync(10,0,function(self,result,entries)
print(self,result,entries)
for loop=1,#entries do
local e=entries[loop].entry
print("at entry",loop)
for key,val in pairs(e) do
print(key,val)
if key=="player" then
for key2,val2 in pairs(val) do
print(" ",key2,val2)
end
end
end
end
end)
end)
<br/>
Example 3 - global leaderboard
FBInstant.getLeaderboardAsync("my_aweome_leaderboard",function (e,error)
print("global leaderboard event",e)
if e then
for key,value in pairs(e) do
print(key,value)
end
else
print("global leaderboard error",error)
end
end)
<br/>
Example 4 - group leaderboard
fbContextId=FBInstant.context.getID()
if fbContextId~="null" then
print("context",fbContextId)
FBInstant.getLeaderboardAsync("Highest Level Achievers."..fbContextId,function (e,error)
print("group leaderboard event",e)
print("group leaderboard error",error)
end)
else
print("You may have tried to access a context high score in solo mode!")
end
