tables and randoms

[DakiLLa]

hi. i have one problem here... well, i have a table with objects. How to get randomly an object and make with him some operations?

lets suppose something like this: 'board from fallout'

rows = 10 
columns = 10 
board = {} 
  
local count = 0 
function createBoard () 
    for i = 1,rows do 
        for j = 1, columns do 
            board[count] = createObject ( 1697, -2274.5741875 + 4.466064 * j, 1858.0903320313 + 5.362793 * i, 102.6078, math.deg( 0.555 ), 0, 0 ) 
            count = count + 1 
        end 
    end 
end 
addEventHandler ( "onResourceStart", getResourceRootElement ( getThisResource () ), createBoard ) 

and i want to attach a marker to one of these blocks (randomly).

function test () 
    rndBlock = math.random (1, #board) 
    m_block = board[rndBlock] 
    m = createMarker ( 0, 0, 0, "corona", 2.0, randInt(0,255), randInt(0,255), randInt(0,255), 150 ) 
    attachElementToElement ( m, m_block ) 
end 
addCommandHandler ( "test", test ) 

but something wrong, i dont know how to make it..can you help ?

I'm noticing that lots of people here are extremely good at giving loads and loads of info.

Do you get any errors?

oh, ye, i see it too.. but sorry, my mistake

well, i have nothing when i write 'test' command.. no errors, no warnings..

Hmm... I can't really spot any mistakes, but you might want to change the color thingies to, say, a minimum of 100. So, 100 + math.random(1,155), since a marker with 0,0,0 will not be black, but invisible. I don't know how many times you tried, but this can also be the reason you didn't see anything.

lol, really working perfect..

i've just tryed to create an object and attach it to block and it works..

well, may be i will have some questions later, so,

thx rob anyway

well another question. If i want to destroy block then i need to remove it from table as i think cse i have warnings when i try to destroy it again (object destroyed, but not removed from table so, you cant destroy nothing). How to do this ? (with my examples ofcourse, with board { } table..)

function destroy ( wut ) 
  for i = #board, 1, -1 do 
    if ( board[ i ] == wut ) then 
      destroyElement ( board[ i ] ) 
      table.remove ( board, i ) 
      break 
    end 
  end 
end
