as the title says code a random number system? i want it to give a random bank pin and it should only be 4digit and non repeating

Re: 4digit random numbers - Universal - 18.01.2011

use:

Above the main():

pawn Код:

new pBankPin [ MAX_PLAYERS ];

And heres the functions:

pawn Код:

stock GenerateBankPin() {
 new pin =  random(9999);
 return pin;
}

stock GivePlayerBankPin ( playerid ) {
new bpin = GenerateBankPin();

for ( new i = 0; i < MAX_PLAYERS ; i++ ) {
 if ( IsPlayerConnected ( i ) && pBankPin [ i ] ==  bpin ) {
  bpin = GenerateBankPin();
 }
}
 return bpin;
}

Havent tested it.

Re: 4digit random numbers - Macluawn - 18.01.2011

with your example the pin could be 3digit, 2digit and even 1digit number.
use

Код:

pin =  1000+random(8999);

with this the pin minimum can be 1000 and maximum of 9999 (1000+8999=9999)

My version of your code -

Код:

stock GenerateBankPin(playerid) 
{
  new pin =  1000+random(8999); //generates a number
  for ( new i = 0; i < GetMaxPlayers() ; i++ )  //loops through all the server player slots (defined in server.cfg)
  {
    if ( IsPlayerConnected ( i ) && pBankPin [ i ] ==  bpin && i!=playerid) pin =  1000+random(8999); //checks if player in that slot is connected and if its pin is the same as the playerid's then it generates a new pin.
  }
  return pin;
}

This isn't the best sollution offcourse and in some cases the number may be the same.

Re: 4digit random numbers - THE_KNOWN - 18.01.2011

afaik random only generates numbers ranging between 0 to max(9999) so i think this wont work (havent tested).

Re: 4digit random numbers - THE_KNOWN - 18.01.2011

@macluan how do make a 8digit number which wont repeat?(for phonenumbers)

Re: 4digit random numbers - Macluawn - 18.01.2011

the same as my other example, but changing the minimum and the maximum ammount.

Код:

phonenumber = 10000000+random(89999999);
