function startlogin()
drawall()
showPlayerHudComponent ( "radar", false )
loc = math.random(#locations) 
smoothMoveCamera( locations[loc][1], locations[loc][2], locations[loc][3], locations[loc][4], locations[loc][5], locations[loc][6], locations[loc][7], locations[loc][8], locations[loc][9], locations[loc][10], locations[loc][11], locations[loc][12], locations[loc][13])
cameratimer = setTimer(function()
loc = math.random(#locations) 
smoothMoveCamera( locations[loc][1], locations[loc][2], locations[loc][3], locations[loc][4], locations[loc][5], locations[loc][6], locations[loc][7], locations[loc][8], locations[loc][9], locations[loc][10], locations[loc][11], locations[loc][12], locations[loc][13])
end, 21000, 0)
theme = playSound("sounds/theme.mp3", true)
setSoundVolume(theme, 1.0)
end
addEventHandler("onClientResourceStart",getResourceRootElement(getThisResource()),startlogin)

so I made a table of locations for the smoothmovecamera, locations are random but sometimes it repeats, how to make it not repeat despite the locations being random? it's the hard way, the easy way is just to make the sequence in order(this seems like the easiest choice) but if possible i'd like them all random but not repeating but it seems hard.

local loc_
if #locations > 1 then
  repeat
      loc_ = math.random(#locations) 
  until loc_ ~= loc
else
  loc_ = locations[1]
end
loc = loc_

To not repeat, you need to repeat .

once again, thank you so much.
