The good news is, your original issue is solved!
The bad news is that now you have to fix your sorting function!
I’m not sure what you mean by this. tableb is the array. You are sorting the contents of tableb. I’m going to call each thing inside tableb an “item”.
Each of these {Type = "Player", Name = "RussellSchutle"} is an item. Your sorting functions receives a and b, which are both items. You don’t know which items it will give you beforehand. Your sort function is supposed to return true if a belongs before b. How you define which items are supposed to go before other items is up to you.
In other words, your sort function is supposed to answer the question, “is a in front of b?”
The line that’s erroring is the following:
if a.Type == "Team" and b.Type == "Player" and Players:FindFirstChild(b.Name).Team.Name == a.Name then
with the following error: attempt to index a nil value [Line 5]
This means that one of the following things must be nil:
abPlayersPlayers:FindFirstChild(b.Name)- or
Players:FindFirstChild(b.Name).Team
We don’t know which one is nil. If I were you, I’d add temporary prints to print all those things out so you can tell which ones are nil.
Some notes:
- If your sort function is inconsistent, it will either error, or
a or b will end up nil at some point. A sort function is inconsistent when it says that an item should be both before and after some other item at the same time. That’s not possible, so it breaks the sorter.
- If there is no player in the game with the name
b.Name then it will error.
I can tell you now that if you have a few players in the array, your sort function will error. It will first ask “is Player1 in front of Player2?” then ask “is Player2 in front of Player1?” You are returning yes (true) for both of those questions, which doesn’t make sense!
Could you elaborate on how exactly you want these player and team items sorted?
I’m guessing that these represent labels for each team or player, like how they would show on the player list. I’m also guessing that you want each player to be grouped with its team label. Additionally, I’m guessing that within each team you want to sort players by score or name and that you want each team group sorted by name.
The following is an example that puts all those guesses into practice:
local Players = game:GetService("Players")
function sortPlayerEntries(a, b)
if a.Team == b.Team then
if a.Type == b.Type then -- sort between two players on the same team
return a.Name < b.Name -- sort names alphabetically
else -- sort between player label and team label for the same team
return a.Type == "Team" -- team labels always come first
end
else
return a.Team < b.Team -- sort groups of team+player labels alphabetically by team name
end
end
tableb = {
{Type = "Player", Name = "RussellSchutle", Team = "TeamA"},
{Type = "Team", Name = "TeamA", Team = "TeamA"},
{Type = "Team", Name = "TeamB", Team = "TeamB"}
}
table.sort(tableb,sortPlayerEntries)
for i,v in pairs(tableb) do
print(game:GetService("HttpService"):JSONEncode(v))
end
