Return a table

[TheChosenPessimist]

local PlayersInZone = pUnit:GetPlayersInZone(1583)

function GetPlayers(pUnit, event)
	PlayersInZone[1]
end

The command GetPlayerInZone() returns the players in the zone. How do i put this in a variable?

You can see my attempt above.

Thank you for any help.

local PlayersInZone = pUnit:GetPlayersInZone(1583)

function GetPlayers(pUnit, event)
for k,v in pairs (PlayersInZone) do
v:dostuff...
end
end

This will get all the players in the zone, and v = the players... So ...

v:SendBroadcastMessage("Mmmmm cake")

Would make all the players in zone 1583 send a message to themselves saying "Mmmmm cake".

This is an easy way to do it, i'm not entirely sure on how to return tables, and there is no table defined either so we can't get a value either.

Hope this helps.

Not quite the explanation i was looking for.

GetPlayersInZone(zone id) : Returns a table containing all the players in the zone.

I would like to specify one of the players.
Like so:
GetPlayersInZone[1]

Get my point?

You could try using

Players = {}
local PlayersInZone = pUnit:GetPlayersInZone(#)
dostuff...
table.getn (PlayersInZone)

That should return the number. Not entirely sure though, try looking around in the guides section otherwise. If you can't find anything i can look this over when i get home as i'm currently in school.

I've never really looked into how tables work in Lua, I would assume that it is columns and rows though.

for _,v in pairs (pUnit:GetPlayersInZone()) do

_ because there is only 1 column, and v would be the rows. So try using v[0] and see if it returns something, use a script like such:

function x()
local i = -1
while (i~=5) do
i = i + 1
print(v[i])
end

There's not only one column? Or is it?

When you use GetPlayersInZone() it returns the following:

GetPlayersInZone = {1, 2, 3, 4, 5, 6}

1-6 being players.

I hope im not missunderstanding you.

GetPlayersInZone() returns an indexed table. Thus if you were to print its content (using "for k,v in ipairs(GetPlayersInZone()) do print (k,v) end") you would get the following:

1      playerdata
2      playerdata
3      playerdata
4      playerdata

Tables in Lua start off with index 1, unlike arrays in C-like languages which start off at 0.

If I were to retrieve the player which is the first in the table I would use GetPlayersInZone()[1]. However, the value returned by GetPlayersInZone() could be nil (as there could be zero players in the zone), thus you'd be better off by assigning the table to a local variable (to avoid polluting the global namespace), then checking if the table contains any playerdata at index 1, and then finally perform an action on the player.
For instance:

local zonePlayers = GetPlayersInZone(some zone);
if (zonePlayers[1] ~= nil) then
    zonePlayers[1]:DoSomething();
end

If you wanted to store the player in another value it is as simple as assigning any other variable, i.e. local player = zonePlayers[1].

Thank you for the answer, this is the answer i was looking for.
