[Solved] A way to randomize variables in a checklist format?

[bruunk]

Hi,

I've recently gotten myself into a very complicated thing. What I'm looking to do is have, for instance, 15 different variables that all have unique info stored in them and randomly give 1 of the 15 variables to a player. However, the tricky part (for me at least) is that I do not want an already given variable to be given to the player a second time. It needs to be set aside once called upon.

Eg: In an event, a player receives variable #13. The next time the variable randomises it will exclude variable no.13 from the random number. If it goes again and the player gets #5, next roll will exclude #'s 5 AND 13. So, if the player rolls 14 times, there should be a 100% chance to get the single, final remaining number.


Is there a way to do this through GUI? I have absolutely 0 JASS knowledge & would be very appreciative for any advice/help

 

[Deserted]

Yes, definitely.

Make an real/integer array of 15.

Let N[A] = Ath element of the array.

Let T = number of taken numbers, by default T = 0.

When you pick a number:
Set R = random integer from 0 to (14-T).
Give N[R] to the player.
Move your array by 1:

For A from R to (14-T-1) {

N[A] = N[A+1].​

}​

Increase T by 1.

>Ath element of the array.
>N[A] = N[A+1]

sorry, dumbass here, what is A exactly?

 

[bruunk]

Deserted, you are truly a legend. Thank you so much. I've attempted to implement what you've said however I'm very uncertain as to whether or not I got it right, especially since I want it to be multiplayer friendly so I needed to add in more arrays to ensure they don't cross over when someone performs an action.

Does this look correct/did I screw something up?

Also, I'm planning on having 5 players total in a game- would I need to create an instance of "N" for each player?

Forgive me, I'm really struggling to understand all this...

Let N[A] = Ath element of the array.

Just a nonspecific index for explanation purposes.

You don't need to have every variable as array, only the RQTracker_Playerblablabla. I'm not sure what you're trying to do with the dialogs, if they're different for each player or not, but if it is then the dialog variable should be array.
I took the liberty to put the deserted's idea into triggers.
Be warned, the indexes here start at 0 and end at 4, which means it's still 5 elements or whatever you may call it. If you're going to use them as players then start at index 1. You won't need the Player((RQRandomizer + 1)) thing.

    • Set VariableSet RQTracker[3] = 3
    • Set VariableSet RQTracker[4] = 4
    • Set VariableSet RQTakenNumbers = 0

• Randomize
  • Events
    • Player - Player 1 (Red) types a chat message containing random as An exact match
  • Conditions
  • Actions
    • Set VariableSet RQRandomizer = (Random integer number between 0 and RQTakenNumbers)
    • -------- use RQTracker[RQRandomizer] for all your actions --------
    • -------- e.g: --------
    • Dialog - Show Dialog[(RQRandomizer + 1)] for (Player((RQRandomizer + 1)))
    • For each (Integer RQLoop) from 0 to ((4 - RQTakenNumbers) - 1), do (Actions)
      • Loop - Actions
        • Set VariableSet RQTracker[RQLoop] = RQTracker[(RQLoop + 1)]
    • Set VariableSet RQTakenNumbers = (RQTakenNumbers + 1)

Basically, Deserted's idea is to keep the index order while picking a random one and removing it.
So...
Indexes: 1 2 3 4 5
3 is picked.
Loop and reassign 3 to 4 and 4 to 5
Indexes: 1 2 3 4

Wrda, you as well have made my day. Many thanks to you. However, I can't seem to get this to work and all the math involved with this is something I have a lot of trouble working out my myself. I set it up as you've shown (or at least I think I did...) and it doesn't seem to function.

To clear things up on 'what' it is I'm even doing with this; there will be an item in a shop where once bought it will bring up a series of random questions. The reason I'm trying to add arrays to the variables is so that when another player comes up and tries to take the questionnaire it does not interfere with the person who is still taking it. (EG. If P1 gets question 10 it does not mean that P2/3/4/5 can no longer see question 10.)

Hopefully you, or someone else, can take a look here and let me know what I'm doing wrong.

When I buy the item it will show Race_dialog_0_setup, however when I click a button the menu simply vanishes. The questions are in an array of their own, independent from the setup.

Players cannot be given variables. It would be like a person eating data. The concepts are philosophically incompatible.

You can map data to players. This data could be a reference to other data such as an array index which can be used with an array variable to retrieve data. It looks like this concept was explained above.

To clear things up on 'what' it is I'm even doing with this; there will be an item in a shop where once bought it will bring up a series of random questions. The reason I'm trying to add arrays to the variables is so that when another player comes up and tries to take the questionnaire it does not interfere with the person who is still taking it. (EG. If P1 gets question 10 it does not mean that P2/3/4/5 can no longer see question 10.)

Use an array of player groups. The idea is that the question entities have a member that represents which players have done the question. When a player answers a question you add them to the player group for that question.

When selecting a question one iterates through all questions and add the indices of questions that do not contain the triggering player inside their player group to an array list. One can then randomly select an index from this array list to give the player a unique question which they have not already seen. The array list is emptied each time so it only ever contains the list of possible questions for the current player.

To prevent multiple players doing the same question at the same time you can add another member to the question entity representing if the question is currently being answered. This could be a Boolean that defaults to false and is set true when a player has been allocated a question and set back false again after the question has been answered. One would extend the possible question list generation code (described above) to only add questions which have that Boolean currently false.

I absolutely do not understand this in any way whatsoever. I've been trying to figure it out but it's not working for me. Is there any way someone can show me what this looks like?

Edit: I don't need the final part, just what's quoted here.

@Pyrogasm thank you, it took me a long time but I think I finally have it figured out for the most part. I only have 2 questions that I can't figure out on my own.

1) At the first trigger group, it says "Set HasBeenGivenThing[(Integer A)] = (Empty player group)" I can't find any setting to set a playergroup to empty, it only allows me to select things like this (or a list of players from 1 to 24, including Neut. Hostile, Neut. Passive, etc.)

Hidden

2)At the very end during the "Player Group - Add ThingPlayer to HasBeenGivenThing[RandomThing]" function, I notice you've managed to put an integer (RandomThing) with an array in without the array attached. Is this a new variable, or is it the same one that should have an array? If so, how is this accomplished?

Set the size of the array. It will initialize all indices up to size with an empty player group making those actions unnecessary.

Otherwise custom script will need to be used. The following sets the player group variable "TempPlayerGroup" to a new empty group which can then be transferred to another variable using standard GUI actions.

set udg_TempPlayerGroup = CreateForce()

Appears to be a typo. The action likely should read...

• Player Group - Add ThingPlayer to HasBeenGivenThing[ThingToGive]

It looks like I finally got it working. Now, the only step is to make sure it works flawlessly while multiple users are taking it at the same time which I will test at a later date. I want to give a massive thank you to everyone who chimed in to help me and for being patient as well. It's awesome to have such a helpful community for wc3 mapping. Thank you all, +rep too.


Edit: I spoke too soon, it seems. The point of this was so that the questions would be random every time, but I'm noticing they are given to the player in a specific sequence: 14, 15, 10, 4, 5, 1, 7, 3, 12, 13, 14(again), 11, 8, 2, 9, 6

Not sure if that has significance, but that's the order they appear every time.
Also, somehow 14 has snuck in there for a second time.

Any thoughts on why this might be?

 

[Dr Super Good]

Any thoughts on why this might be?

World Editor defaults to testing maps with a fixed seed. Hence the same sequence of RNG calls results in the same rolls. One can turn off this option for testing.

In multiplayer the RNG is seeded before every game start. Hence this is of no consequence.

Also, somehow 14 has snuck in there for a second time.

Off by one error? Maybe when building a list of possible questions.

You can debug the trigger by printing messages at the various stages of execution. For example you could print the state of all the questions after one is selected to confirm that the questions are changing as expected. One could also print the list of selected possible questions before one is picked to see that it is selecting the questions correctly.

Without seeing your triggers all we can do is guess as to what the cause is.

Ah, I never would've guessed. Your insight is on another level.

Without seeing your triggers all we can do is guess as to what the cause is.

I'll post my triggers here in case, but I'm now wondering if it's because of the aforementioned 'issue' of the default seed. It could also be this additional trigger that I've added to initialize the whole thing, maybe it doesn't count the first question asked.

Edit: skip this, issue is resolved.
