Problem with Random

RUPAS

hi all, I have a small problem with the random, I'm making a game with boards, a trivial, I have 200 questions and random, the probability of a recurrence is 0.00025 and yet are repeated a lot, do not understand, there is some how to improve this problem?

Why not just use attributes to store when a question has been asked, and if it has already been asked, don't ask it again? Maybe clear those attributes every x seconds if you don't mind repeats (but just want less frequent repeats) ?

I would just wait for writable tables. Then you'll be able to delete questions from the table after they are asked. Writable tables are supposed to be released in .9.9.93 this week.

You can tend to get that if you just use plain random. Sometimes you get better results if you do something like random(game.milliseconds)%5
That way you avoid things like, if you start a level twice, the first thing you seed being the same.

Thanks all!

I have this rule:

"change atribute game.whatquestion to random(1,tablerowcount(game.TBPACKQUESTION)"

is correct?

this pack contains 200 questions, but repeats much,

some help?

hotMagic

That sounds good, but I was saying above, just to really get it random, something like this (and forgive me i don't have GS open, so it's not exact)

random(1, game.milliseconds)%tablerowcount(game.TBPACKQUESTION)

That way you are getting a random from the game timer which is all over the place, then the % allows you to constrain it to how many questions you have. Like 200 for example.

If you just make a test game with a blank square that shows the results of that formula, and have it do that whenever you click it, you'll probably see some really random selections.

any help? I prove random(1, game.clock.milliseconds)%tablerowcount(game.TBPACKQUESTION) but no is correct

@Rupas … use the new read/write tables in .93
create/import the original table
create a blank Table for runTime usage

gameAttribute: index type … name: what? … this will be your row #

Copy Table behavior … original to temp
use the Add/Remove behavior to delete used rows in the temp table

@MotherHoose yes I use, but my game is a quiz, if I delete the rows can not play again, or if you can?

RUPAS

oh yes, I think I understand I will try

MotherHoose

@Rupas … good you got it! … with the incomplete directions (now edited)

for restart or replay have a button that changes the what? to 0
then copies the original to temp
