sorry right i missed the ! which in this case is verry important .. hehe also if that is the case i have to say u can't use the +1 method cause it will never return 0 = > if the value is 1-20 the if statement will never be true ..

aye your way is great if i wanted to execute something different on a number returned but all i wanted was something to be executed with a 1 in 20 chance which [!rand 20] did perfectly cheers

Hey guys

All i needed was a small easy way to make my bot kick someone with a 1 in 20 chance of them triggering the proc kinda a russian roulette thing so 0 - 19 or 1 - 20 would do exactly the same thing at the end of the day thanks again for your replys hope you all had a good xmas.

easyest way is to use switch

Code:

switch  -- [rand 20] {  "0" {    # code   }  "1" {    # code   }  "2" {    # code  }  #... i gues you get the picture ..}

or ..

Code:

switch  -regexp [rand 20] {  "(0|3|6)" {    # code   }  "(1|4|7)" {    # code   }  "(2|5|8)" {    # code  }}

if you don't have that mutch conditions.. to shorten the code.. don't see the use but hell..

The result of [rand 20] will allways be a number betwen 0 and 19 (0 and 19 included), while the result of [expr [rand 20] +1] will be from 1 to 20 (1 and 20 included). And if you read again he did said 1 to 20 not 0 to 19.

that's exactly what i meant
however, he didn't say "1 to 20", he said "1 in 20" (chance), so if you take 0-19 or 1-20 doesn't matter

Nevermind. You haven't got my "1 to 20" point.

0 to 19 are exactly 20 numbers, hence 1 in 20

@caesar: that's needed if he wants numbers from 1 to 20. but if he just wants a 1 of 20 chance, demond's solution is fine

Hey guys merry xmas.

Need a hint on how to code probability

Instead of just using rand to choose wether something is executed or not im looking for a way to give it say a 1 in 20 chance of being executed rather that a 1 in 2 chance. I did a search for probability but came up empty.

Any help would be greatly appreciated.

Thanks again.

Jon.
