What's wrong with getting the UUID in this function?

[Gamerboy59]

Hi,
I'm about getting the UUID of a user to add them to a text file. It somehow doesn't work. :/

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

local addusertofile = function(OtherPlayer)     if OtherPlayer:GetName() == Split[3] then         if OtherPlayer:GetUUID() == nil or OtherPlayer:GetUUID() == "" then             friendusername = cMojangAPI:GetUUIDFromPlayerName(Split[3], true)         else             friendusername = OtherPlayer:GetUUID()         end         local file = io.open(friendDir.."\\friends.txt", "a")         file:write(friendusername.."\n")         file:close()         Player:SendMessageSuccess("Friend added. You can check with /friend [playername]")     else         Player:SendMessageFailure("Fail")     end end if not cRoot:Get():FindAndDoWithPlayer(Split[3], addusertofile) then     Player:SendMessageFailure("Invalid Playername") end end

=> Always says "Invalid Playername" ingame so FindAndDoWith... was not successfull?!

Try this instead:

1 2 3 4 5 6 7 8 9 10

local UUID = cMojangAPI:GetUUIDFromPlayerName(Split[3], true) if (UUID == "") then    Player:SendMessageFailure("Invalid Playername")    return true end   local file = io.open(friendDir .. "/friends.txt", "a") file:write(UUID, "\n") file:close() Player:SendMessageSuccess("Friend added. You can check with /friend [playername]")

You're using FindAndDoWithPlayer, but that means he already came online at least once. This means his UUID is already known in the database.

I've got now:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

local addusertofile = function(OtherPlayer)     if OtherPlayer:GetName() == Split[3] then         friendusername = OtherPlayer:GetUUID()         local file = io.open(friendDir.."\\friends.txt", "a")         file:write(friendusername.."\n")         file:close()         Player:SendMessageSuccess("Friend added. You can check with /friend [playername]")     else         Player:SendMessageFailure("Fail")     end end if not cRoot:Get():FindAndDoWithPlayer(Split[3], addusertofile) then     local UUID = cMojangAPI:GetUUIDFromPlayerName(Split[3], true)     if (UUID == "" or UUID == nil) then         Player:SendMessageFailure("Invalid Playername")     return true     end     local file = io.open(friendDir .. "/friends.txt", "a")     file:write(UUID, "\n")     file:close()     Player:SendMessageSuccess("Friend added. You can check with /friend [playername]") end

Still invalid player.

You don't need FindAndDoWithPlayer. Try my code instead of all your code..

What's the difference between cClientHandle UUID and MojangAPI UUID call? I though the latter one uses more bandwidth (performance?).

[NiLSPACE]

cClientHandle:GetUUID is a member variable. You can only get it when a player is online. cMojangAPI, when using cached only, will get the info from a sql database next to the executable. It won't affect the bandwidth at all.

I see, thanks for explaining.

I've got now the following code:

1 2 3 4 5 6 7 8 9

local friendusername = cMojangAPI:GetUUIDFromPlayerName(Split[3], true) if (friendusername == "" or friendusername == nil) then     Player:SendMessageFailure("Invalid Playername")     return true end local file = io.open(friendDir.."\\friends.txt", "a") file:write(friendusername.."\n") file:close() Player:SendMessageSuccess("Friend added. You can check with /friend [playername]")

Still invalid playername. Is the MojangAPI broken?
I tried another function (/useruid <friendusername>):

1 2	local friendusername = cMojangAPI:GetUUIDFromPlayerName(Split[2], true) Player:SendMessageInfo("Found player:"..friendusername)

Returns nil while the player definitely exists.

The username you're trying to get did already come online right? Also, I believe the function is case sensitive. If I search for gamerboy59 while you logged in as Gamerboy59 you wouldn't show up.

No.

Yes, tried case sensitive doesn't matter.

You are using true in the function cMojangAPI:GetUUIDFromPlayerName(Split[2], true).
True means that only the local cache will be used to lookup the uuid of the player. Set it to false, then it will connect to mojang to get the uuid.
cMojangAPI:GetUUIDFromPlayerName(Split[2], false)
