Random Plate bugs help - Stefand - 09.12.2012

pawn Код:

stock getRandomLetter() {
    return 65 + random(52); // ASCII Code of capital A is 65 + 2 * 26 for all other chars in alphabet.
}

stock GetFreeVehiclePlate()
{
    for(new v = 0; v < MAX_VEHICLES; v ++)
    {
        new VPlate[255];
        new randnumb = 1 + random(9);
        format(VPlate, 255, "%c%c%c - %d%d%d", getRandomLetter(), getRandomLetter(), getRandomLetter(), randnumb,randnumb,randnumb);
        if(strcmp(Vehicles[v][Plate], VPlate, true)) return v;
    }
    return -1;
}

Its supposed to do for example AAA - 111 or BAS - 234 just random the first 3 a-z and last 3 0-9.

but it made this: яFCliams

which isnt correct...
Can someone help me out

Re: Random Plate bugs help - Vince - 09.12.2012

Lower case letters don't follow the upper case letters directly in the ASCII code.

pawn Код:

const charset[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";

new VPlate[8]; // don't waste resources
format(VPlate, sizeof(VPlate), "%c%c%c-%03d", charset[random(sizeof(charset))], charset[random(sizeof(charset))], charset[random(sizeof(charset))], (100 + random(900)));

Sorry, use new const instead of just const. I have that charset variable as a stock in one of my includes, that's why I didn't notice at first.

pawn Код:

stock GetFreeVehiclePlate()

        new const charset[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        new VPlate[8]; // don't waste resources
        format(VPlate, sizeof(VPlate), "%c%c%c - %03d", charset[random(sizeof(charset))], charset[random(sizeof(charset))], charset[random(sizeof(charset))], (100 + random(900)));
        if(strcmp(Vehicles[v][Plate], VPlate, true)) return v;
    }
    return -1;
}

shows a stupid thing like яFCliams aganin..

Ty this...

pawn Код:

stock GetFreeVehiclePlate()
{
    new VPlate[10];
    for(new v = 0; v < MAX_VEHICLES; v ++)
    {
        format(VPlate, sizeof(VPlate), "%c%c%c - %d", random(25)+65, random(25)+65, random(25)+65, (100 + random(900)));
        if(strcmp(Vehicles[v][Plate], VPlate, true)) return v;
    }
    return -1;
}

Let me check

Re: Random Plate bugs help - Stefand - 09.12.2012

Nope still doesn't work...

this code gives you a string of the type AAA -123

pawn Код:

if(strcmp(Vehicles[v][Plate], VPlate, true)) return v;

this code probably is the problematic code.

how are you calling the function?

Re: Random Plate bugs help - Stefand - 09.12.2012

it is to check if the plate that is been created isn't already in use.
