Random number with condition

[micca]

How can I set random number variable two times, but for the second set I need to set it without the number, which was set in the first set of the variable?

Set it normally the first time. Then, to get the second number, increment the first by another random int with a one-smaller range and take the result modulo the expected output range. (If you need a lower bound other than 0, it's a simple arithmetic operation to shift the results.)

Example:

• Set SomeVar = (Random integer number between 0 and 10)
• Set SomeVar = ((SomeVar + (Random integer number between 1 and 10)) mod 11)

(I assume you want to do something between the two operations. Otherwise, you'll of course want to assign to a different variable the second time.)

After a few tests I found out, that this is not I am looking for. Is there a way to use random number from some set of numbers (the same way as random unit from N unit group or random player from N player group, etc.)? Then I will easily remove this number from the set, so it would only have the numbers, which have not been use yet.

Can't you just make another 'If' to random again if the 2º number is Equal to the 1º roll? Sorry if I didn't understand your question.

That would be really hard to implement, because I need 10 numbers, which as they are randomed, they cannot be randomed again. I just asked if there is an easy way like with unit groups, that it will number group and I will just take random number from this group and then remove it, so it cannot be randomed again.

I need this to work for the numbers the same way:

• Set unit_group = (Random 1 units from (Units in (Playable map area)))

If I understand correctly, you want to pick a random item from a set (regardless of type), right?

All you have to do is pick a random integer N between 0 and the number of items in your set.
Then, your random item will be the one at index N.

• Set N = (Random integer number between 1 and ItemsInSet)
• Set PickedItem = Set[N]

You can then remove the item from the set if you dont want it to be used again.

Maybe this can help.

Thank you all for your answers, this map is almost what I want.

For small number ranges make a set (using an array) of the numbers, select a random element and then remove that element from the set, repeat as required.

For a large number range you track which numbers have been rolled, and then keep retrying a random number until you get one not in that set. To prevent potential infinite loops you might want a safety clause that after 10 or so attempts you default to a value, possibly generated by the rolled number list.
