i'm editing the tv vex plugin, and it sets kicked people to freq 0 initially, i changed this to 85, but now i want this to be a random freq in 3-99 instead

sendPrivate(parse->item, "*setfreq 85");

thats what it is right now, i've read over the mervbot tutorial, with the section on random numbers and players, but it failed to work, and yes, i did include time.h

my guess is that my syntax was wrong or something, this is what i thought it should have been:

srand(time(NULL));
rand();
int tempkickofffreq = (int) (99 * ((float)rand()/RAND_MAX));
sendPrivate(parse->item, "You were kicked from the freq");
sendPrivate(parse->item, "*setfreq " + tempkickofffreq);

tho that would do 0-99 correct? (still didn't work btw)
i also tried putting the last tempkickofffreq as: int(tempkickofffreq)

and vegito suggested this to me:

srand(time(NULL));
int Random = rand()%51 + 1;
sendPrivate(parse->item, "You were kicked from the freq");
sendPrivate(parse->item, "*setfreq " + Random);

none have worth thus far, i'm hoping someone here will know what i'm talking about and can correct me

ty in advanced

Code: Show/Hide inline int randrange(int low, int high) {     return rand() / (RAND_MAX / (high - low + 1)) + low; }

It crashed my program when I passed values with a too big difference to it I think, but I guess you won't have such problems.

Should work:

Code: Show/Hide rand() * 97 + 2

sendPrivate(parse->item, "*setfreq " + tempkickofffreq);

should be:

sendPrivate(parse->item, "*setfreq " + (String) tempkickofffreq);

[bigshot3754]

ty you three, i'll try yours first underlord

[Mr Ekted]

rand() % 97 + 3 will result in numbers from 3 to 99

rand % 97? you mean rand() * 97?

No, rand gives an int. The modulo operator (%) will take the remainder when devided by 97. Means you get a random number from 0 to 96.

+3 gives the proper offset.

I thought rand gave a decimal between 0 and 1

[Deadly]

blah, that random stuff confuses me.. i tried making a lottery plugin didnt work, gay random

its wierd.. it chooses a random number, then i make it say "*arena Number: " +(String)temp or whatever, for testing so i can guess the number and see if it works.. but it didnt work, i think when it sends the arena its choosing a new number by doing +(String)temp..

Code: Show/Hide          if(countdown[0] == 14){             srand(time(NULL));              rand();             int temp = (int) (51 * ((float)rand()/RAND_MAX));             sendPublic("*arena Number for this round is " +(String)temp +".");          }

if someone can help me out with that.. that would be good

that code works fine deadly

rand() returns an int between 0 and RAND_MAX (32767)

never use something like 'rand() % 97'. The way the random number generator works, doing that will give 'less random' numbers, and often cycle between odd/even numbers.

[Cyan~Fire]

Ooops. I got confused with BASIC for a sec there.

[D1st0rt]

shows how much I know, in Java Math.random() returns a double between 0 and 1

Can we see a little more of that code, please?

[50% Packetloss]

Uint16 random_range(Uint16 lowest_number, Uint16 highest_number)
{
if(lowest_number > highest_number){
swap(lowest_number, highest_number);
}
Uint16 range = highest_number - lowest_number + 1;
return lowest_number + Uint16(range * rand()/(RAND_MAX + 1.0));
}


this is the function that i have used to do random ranges. I think i got it off a website. Its more efficient to just use the modulus operator.

Merv comes with a prng

[bigshot3754]

ok, this is still failing to work for me

[Cyan~Fire]

Replace

Code: Show/Hide sendPrivate(parse->item, "*setfreq " + (String) tempkickofffreq);

with

Code: Show/Hide sendPrivate(parse->item, String("*setfreq " + (String) tempkickofffreq)).msg;

Should work.

Really it's better do do something like:

Code: Show/Hide String message("*setfreq"); message += tempkickofffreq; sendPrivate(parse->item, message.msg);

More lines of C++, less lines of ASM (without optimization).

[bigshot3754]

i know this is an old thread, but thank you very much cyan~fire, what you posted worked perfectly

if anyone knows how to make this 2-99, that would be great:

Code: Show/Hide int tempkickofffreq = (int) (99 * ((float)rand()/RAND_MAX));

[Cyan~Fire]

Wow, you really didn't understand anything we told you?

First of all, rand() returns an int. Why are you float-ing it?

Second, learn what the % operator does and then modify the code yourself (to use it).

[Underlord]

Code: Show/Hide srand(time(NULL)); rand(); int tempkickofffreq = (int) (97 * ((float)rand()/RAND_MAX)) + 2;

[Dr Brain]

Code: Show/Hide int tempkickofffreq = (rand() % 97) + 2;

[bigshot3754]

Again, thank you for the resonses

@Cyan~Fire:
I'm very sorry I couldn't comprehend much from reading some lines of code involving the simplicities of random numbers. I'm always thankful for the help, but nothing provided to me so far has actually worked (what you gave me compiled fine but doesn't work when the command is sent :S) but I'm not complaining, I'm going to continue to use the items given here and hopefully get it working properly.
