Need help with randomizing variables

[golden_thy89]

Is there a way to do this? 8)

Sure is.

code:

var a:int a:=Rand.Int (1,10)

1 is the lower limit, 10 is the upper limit. Change the parameters to whatever.
Also, there is probably something about this in the tutorials section. Be sure to check it before you post.

what about randomizing various variables, say we were making a blackjack game and we only wanted 2 out of the many various cards to pop up, but they must be randomized, how could we go that.

[lyam_kaskade]

You could put all the cards in an array.

code:

var cards:array 1..52 of int var card1, card2 for i:1..52    cards (i):=i end for %draw cards card1:=cards (Rand.Int (1,52)) loop    card2:=cards (Rand.Int (1,52))    exit when card2 not= card1 end loop

Hmmm...that's probably giving you too much help.
Oh well. Be sure to check out the walkthrough.

[lyam_kaskade]

Which part doesn't work?

[golden_thy89]

for some reason the for dosnt work

[lyam_kaskade]

Oh right.

code:

var cards:array 1..52 of int var card1, card2:int for i:1..52    cards (i):=i end for %draw cards card1:=cards (Rand.Int (1,52)) loop    card2:=cards (Rand.Int (1,52))    exit when card2 not= card1 end loop

Though you should have been able to figure that out... Read the tutorials

for turing to randomly select something to do the best command to use is the "randint"

The function, Rand.Int(), is much more flexible than the procedure, randint().
