Generating non-repeating Random numbers?

[Samer]

Hi,

So I've set up a frame with a counter in it. And have 2 lines of code, which are:

Always - Set countSelector to RRandom (1, 4)
Every Second - Set Counter to countSelector


Now, as you may have figured out, every second the counter is set between a number of 1 and 4.

My question is, how can I change up this code in order to make sure the counter doesn't display the same number twice in a row?

Thanks a lot.

Samer.

If you don' t mind using an Extension, then You could use the "Random Pool" or the "Random Multipool"-Extension.
It allows You to create a Pool of Numbers and then "draw" these Numbers off from the Pool. Every Number can only be used
once (until you refill the Pool ofcourse).

With kind regards,

You could also use a simple List-Object and draw the Numbers at Random from the List

Here is a random pool thing. Maybe it will help?

even in random sequences, there is a chance for repeated numbers... so if you still want to ensure the same number isn't regenerated you can create a variable called PreviousPick and use it to remember the previous number.
CountSelector= RRandom (1, 4).
if CountSelector<> PreviousPick then PreviousPick = CountSelector

or you could just check the counter... if counter <> countSelector then counter = CountSelector

Hi,

Unfortunately I'm creating this game for Android, so none of the extensions will work for me.

And to Tuna's suggestion, I'm not quite sure where you're coming from. Surely if CountSelector <> PreviousPick then it would only run this line if it does not match the previousPick? But the previousPick will always match CountSelector since it sets previousPick to CountSelector everytime it generates a random number. Or have I understood it completely wrong?


Thanks.

Hi,

I really appreciate your suggestions, Snail, but I'm still not getting a clear and logical picture in my head. What I've got at the moment is this:

if countSelector <> previousPick
-set previousPick to countSelector

if countSelector = previousPick
-Start loop "ran" 2 times

On loop "ran"
-Set countSelector to RRandom (1, 4)

Every Second
-Set Counter to countSelector



But for some reason, this still isn't doing the trick. :/

Any clarification would be much appreciated.

Thanks.

The List-Object should work in Andoid too. You can place it outside the Frame if you don' t want it to show in the Frame or you can even make the List invisible during Runtime
I think it' s the Easiest Way to achieve what You want. You can even populate the List with Numbers at Runtime and then draw numbers off from a Random-Line in the List and then delete that Line in the List.

Here is a cross platform example in just 3 events... should be of use! You can make the list object 'hidden' and take it out of the playarea for your games.

min-max-random.zip

Just change the Alterable Values (MinRandom and MaxRandom) to change the number scope from and to.

Hi,

Thanks Danny for the attached example. However I don't think this will work in my case, since the 4 Random numbers I need generated need to be reused rather than deleted from the list.

Any other ideas? :S

I really appreciated this, btw.
