There is one last issue I didn't address. You have several options. The problem is that any missing key will evaluate to nil, not false. nil == false evaluates to false. Several options include...

1) Set taraaffliction to contain every affliction, set to false. Set them to true as you afflict, false as you know they're cured.

2) use NOT. NOT changes true to false and false to true. it also changes 'nil' to true. You would do that like so:

if tarafflictions[v] == false then

changed to:

if not tarafflictions[v] then

Either option works!

This is just one possible result:


venom_priority = {
  "slickness",
  "asthma",
  "deaf_strip",
  "sensitivity",
  "powersap",
  "blindness",
  "relapsing",
  "clumsiness",
  }

tarafflictions = {}

tarafflictions.slickness = true



function doattack()

  for k, v in ipairs(venom_priority) do
    if not tarafflictions[v] then
      Note ( "Venom: " .. v )
      break
    end -- if
  end -- for

end -- func

Another possbility!


venom_priority = {
  "slickness",
  "asthma",
  "deaf_strip",
  "sensitivity",
  "powersap",
  "blindness",
  "relapsing",
  "clumsiness",
  }

tarafflictions = {}

for k, v in pairs(venom_priority) do
  tarafflictions[v] = false
end -- for


tarafflictions.slickness = true



function doattack()

  for k, v in ipairs(venom_priority) do
    if tarafflictions[v] == false then
      Note ( "Venom: " .. v )
      break
    end -- if
  end -- for

end -- func

In fact, you can put


for k, v in pairs(venom_priority) do
  tarafflictions[v] = false
end -- for

In a function to reset the table.

For the first example, you can reset it by simply doing:


tarafflictions = {}

Thank you so much for the examples Fadedparadox. I at least understand more of what you are saying, As for your examples, I've tried them.. without the:


doattack(...)

It refuses to call the tarafflictions variable. How do I make it call that variable that's called globally?

I'm not certain what you mean. tarafflictions is, in the example, global so can be called from within another function/etc, or globally.

Can you give an example of what will not work?

Your use of language is confusing me. You don't "call" variables. Are you saying the variable has a different value to what you expect?
