Pick a random?

[FWCentral]

Ok i have 3 numbers, How can i pick a random number out of them?

[Castillo]

math.random 

[FWCentral]

Doesn't that only work say if i put math.random(1,20) it will pick a random number between them? and i should have said the 3 numbers are non consecutive.

Create a table.

E.g:

local numbers = { 1, 5, 8, 10 } 
  
outputChatBox ( numbers  [ math.random ( #numbers ) ] ) 

[FWCentral]

The numbers are coming from a db, so like this?

  
local skins = ( skin1, skin2, skin3 ) 
skins [ math.random ( #skins )  ] 
  
  

[Castillo]

No, wait, you're using parenthesis, not { }.

local skins = { skin1, skin2, skin3 } 
skins [ math.random ( #skins )  ] 

[Stanley Sathler]

I guess is like this, not?

local skins = { skin1, skin2, skin3 } 
skins[math.random(#skins)] 
-- Note: I used "{ }", and not "( )" in table declarations

Forget, you fixed your post.

@StanleySathler: It has to get a random index from the table, so you have to give the max index in math.random, which you get with: #table, only if is a indexed table of course.

Solidsnake, yes bro, I got it. I fixed my post, I had forgotten this detail.

You're welcome.

I didn't want to start a new topic but i got another problem, Im trying to spawn a player;

  
function spawn(source, spawn) 
outputChatBox("work1") 
local gang = executeSQLQuery("SELECT gang FROM Spawn WHERE name = ?",tostring(spawn)) 
if gang == "none" then 
outputChatBox("work2") 
elseif gang ~= "none" then 
outputChatBox("work3") 
end 
end 
  

It shows in the chatbox work1 and work3 but the gang in the db is "none" (without quotes)

[Castillo]

function spawn ( source, spawn ) 
    outputChatBox ( "work1" ) 
    local gang = executeSQLQuery ( "SELECT gang FROM Spawn WHERE name = ?", tostring ( spawn ) ) 
    if ( gang ) then 
        local gangName = gang [ 1 ] [ "gang" ] 
        if ( gangName == "none" ) then 
            outputChatBox ( "work2" ) 
        else 
            outputChatBox ( "work3" ) 
        end 
    end 
end

It works thank you! but how does this work? local gangName = gang [ 1 ] [ "gang" ]

[Castillo]

What do you mean by how does it work? you can google to check how SQLite works .

P.S: You're welcome.

[Stanley Sathler]

The SQLQuery return a table. So you access the first item from table (gang[1]) and the column (["gang"]). Is it, I think.

Ok thanks Solidsnake and Stanley

Indeed, that's exactly what it is.

No problem, FWCentral.
