I ended up in a very specific situation, I need to choose index 46 of the AOB if it exists, but if I do an if and it doesn't exist, the "out of bounds" error will obviously occur, so... what do I do? Is there any way to ignore this error and jump to the else block?

Code:


ResultadoAobGuidlineP1 = AOBScan("00 00 31 40 00 00 00 00 00 00 2C 40")


if ResultadoAobGuidlineP1[46] then
    EnderecoParaGuidlineP1 = ResultadoAobGuidlineP1[36]
else
    EnderecoParaGuidlineP1 = ResultadoAobGuidlineP1[14]
end

You can check how many elements there are with the "Count" property
Code:
local results = AOBScan('...')
local whatever

-- AOBScan returns nil on failure
if results then
  if results.Count >= 47 then
    whatever = results[36]
  elseif results.Count >= 15 then
    whatever = results[14]
  end

  -- don't forget to destroy the stringlist (if it exists)
  results.destroy()
end
