Unique Licence Plates - jamesb93 - 17.06.2012

Hey,

I'm looking to create something to ensure the license plates are totally unique. I have some code that I have been using here:

pawn Код:

new LetterList[22][] =
{
     "A", "C", "D", "E", "F", "G", "H", "J", "K", "L", "M", "N", "P", "Q", "R", "T", "U", "V", "W", "X", "Y", "Z"
};
            
for(new i = 0; i < MAX_VEHICLES; ++i)
{
      while(vInfo[i][vPlate] == randomplate)
     {
        format(randomplate, sizeof(randomplate), "%d%d%d %s%s%s", random(9),random(9), random(9),LetterList[random(sizeof(LetterList))], LetterList[random(sizeof(LetterList))], LetterList[random(sizeof(LetterList))]);
      }
}

Right now ofcourse it tells me that 'randomplate' is not indexed.
error 033: array must be indexed (variable "randomplate")

I don't want to base it off vehicle ID's either. Can someone help me make this work? or propose a better solution?

BTW, It doesn't have the full alphabet because I dident want to see confusion between letters.

Cheers!

Not sure but when the Error is "Must be indexed" i just put something like

pawn Код:

UsingMortar[playerid]

In your case,

pawn Код:

while(vInfo[i][vPlate] == randomplate[vehicleid])

Nah, Its not an array. It's only a string I use to compile the plate.

Quick bump. Still can't figure out the best way to go about this.

Not sure, but is your variable actually a string?

pawn Код:

new randomplate; //Wrong

new randomplate[stringlengthhere]; //Correct

pawn Код:

while(vInfo[i][vPlate] == randomplate)

what is this supposed to do? compare strings? 1 char maybe? does creating a string to assign it to the plate require any presumptions?

Thats a quick mock-up I made ofc^ I'd be using strcmp.

Post all of the code relating to this. We can't do much with just that.
