Any help to get three random unique flags values :?

[Presidium]

Hi guys,

I'm asking for some help here. I need to get some three random numbers from 1 to 10.

Flag01 set random value: 1 - 10
Flag02 set random value: 1 - 10
Flag03 set random value: 1 - 10

But they must be unique, and cannot be repeated.

Three different flags with three different values.

I know I can do it with a bunch of FLAG EQUAL FLAG and FLAG IS LESS THAN FLAG checks. But it's so tedious and long, and it has no sense to make so many triggers and conditions for such easy piece of code... (I wish there was a FLAG NOT EQUAL FLAG).

Any help would be greatly appreciate!

Thank you!

Hi, here a script to do that (and a .miz to test -> flags are defined every 5 seconds with message that gives values) :

local values = {1,2,3,4,5,6,7,8,9,10}
for j = 1, 3 do
local i = math.random(#values)
trigger.action.setUserFlag("0"..j, values[i])
table.remove(values, i)
end

@toutenglisse has the right answer here with minimal processing.

I missed the "unique, and cannot be repeated" part

In your example, nothing prevents results to be the same.

Hi, My take would be like this, first generate the three random values:

 

 

Then regenerate the 2nd number until it is different from the other two:

 

 

Finally, regenerate the third number until it too is different from the others:

 

 

For testing, the last triggers displays the three flags:

 

 

Runs like this:

 

 

Here is the mission if you want to try it:

Wow! I love to see so different approachs to the same problem!

Removing values for a table was a neat idea toutenglisse!

But I will stay with Rudel_chw approach: just 3 lines and do not have to use a script/predicate LUA. Clean, fast and easy, just perfect!

I'm working on a civilian mission for the huey and you've save me so many lines of checkings and conditions!
Thanks **A LOT** guys! I TRULY APPRECIATE YOUR HELP!!

I love you ALL!!! :)))

@Presidium and @Rudel_chw, I've tested Rudel's random number miz and I can't say why, but same numbers still happen.

Attached modified miz (modified the 3 flags trigger to fire every 4 seconds, and added a time message and made the messages continuous - updated every second)

I tested because my hesitation with this method was : maybe flags would still be activated with potential same numbers and detected like this before being changed, due to "switched cond" triggers being evaluated every sec. But it seems that this is not an issue, while there is another one. (unidentified, but soon or late flags are activated with same numbers)

FWIW with script the 2nd and 3rd flags can only be activated with values from 1 to 10 but without value(s) of previous flag(s).

Hi @toutenglisse .. you are correct, I tested my triggers more times and it did in fact sometimes generated repeated numbers .. my two SWITCHED CONDITION loops were not working properly. I had to add two explicit flags to get the loops to work:

 

 

I tested this a lot of times and now seems to work well

Hey, I just took a look and still same flags values occures. No clue what's wrong though.

  I've checked and re-checked my logic, and can't find the fault ... pity

Perhaps something is up with Switched Condition. I think I made a unit spawner that had to randomize the order of 4 groups, but it used Continuous Action if I recall. Maybe that trigger type will work as expected?

The problem with Continuous triggers is that they execute once per second from the start up to the finish of the mission, not only producing overhead, but on this case it wouldn't be useful that the trigger altered the numbers after the moment the were needed.

Hi guys, nice logic challenge

I have modified a little Rudel's approach (thanks @Rudel_chw for template) , see attached.

Basically, i have generated the flags one after other: first flag is generated, the after 1 second, flag two comes and check if is equal with F1.

If yes, regenerate, else, after 1 second, Flag 3 enters, check again, regenerate if equal with F1 or F2, else all good, show result after TIME MORE 20 seconds.

I did several tests, all seems ok, but let me know your test results.

At the end, the little snippet shared by @toutenglisse seems the easier solution here.

And this is my 'script' version (tested and working) that is far quicker and easier than using the ME and setting flags etc..

-- 1. Create a MISSION START Trigger, with no condition and the action of do script file and load this file.

-- 2. Then when you want to generate them, create a trigger with the action of 'do script' and do this:

-- RFVG:SetFlagsToRandomValuesBetweenMinAndMax(1, 10, "A", "B", "C", false)

-- The last value - if true will output to the screen for everyone. If false then it won't.

The 1 and 10 are the MIN and MAX - change these however you want with each call you make. 

A, B and C are the flags you're using, either numbers or words but they have to be in the quotes.
