non-duplicate random number generation

The topic title is a mouthful, but accurate lol. I have a game I'm tinkering with titled Froggo (at least it's called that for now) it involves the play area having random numbers from 1-75 on 24 different tiles. You can play the prototype on yoyo here To get the numbers on the tiles, I put in the tile object creation event:

number=floor(random(74))+1

Using the floor command gets rid of any decimals, but I'm running into a problem with duplicate number (ie number 25 on 6 different tiles). The ideal is to have no duplicate numbers on any of the tiles. I know putting the code in the create event probably isn't the smartest way to go about it, but I'm just not sure how create the desired result. Any pointers?

Regards,

John,

can you give more actions for it like if there was something in the draw event

What I'm missing is a way to determine when there's duplicates, and then take some sort of action to correct it... or something I'm suspecting I need something in the room create code, I just can't quite wrap my mind around what I would need to meet my desired result :p Thanks all the same though!

maybe something like this

room code

Code:

global.empty=0

then on your event put it in the step event

Code:

if global.empty=0
{
number=floor(random(74))+1
global.empty=1
}

then try that if that does not work you might have to make different varibles and objects for each square

lol, we were both thinking along the same lines I think something like this might do it I'm going to try it out

Hey! were'd my last message go!?! I had a bunch of code writting out similar to what you have, and now it's gone! >:c anyway, I'm going to try it out

k

Ug, it didn't really work out, even if I set up global variables to account for the numbers, I don't know how to make the object "reset" to try again. Even if I could, in theory, it could go on forever until it reaches a untaken number. I'm stumped

no i meant like
on the second on

room create

Code:

global.squareone=0
global.squaretwo=0
//ect.

step

on sqaure one

Code:

if global.squareone=0
{
number=floor(random(74))+1
global.empty=1
}

and same for the rest of square accept on square two the varible would be global.squaretwo ect..

Sorry, I don't get it How would that prevent duplicate numbers? Thank you for helping! I'm not smart lol

... wow...

This topic is still open! i can't figure it out Thanks to all who have replied

could you like give me a gmk whith just the blocks with the numbers in it

I could do a quick mock-up, I'll make it asap thanks!

i will probally finnish it on monday if don't get on the computer

Posted a GMK on our SkyDrive to help clarify the problem, you can find it here:

Thanks to all who reply

Well you could just do the really hard thing to do and make like 50 individual tiles. And then if the number of two(or more) tiles is the same all the tiles get new numbers.

One thing I'm trying to avoid is having the numbers change after the object is created (although if I can't figure out a way to do that, I guess I'll have to live with it ) That idea isn't bad though, I'll have to keep kicking around that idea I didn't know this would be so hard

Thanks for your help!

Just to let you know I meant only the tiles that have the same numbers.

Fixed the problem using a ds_list! Thanks for helping everyone!
