how do I get this to work, the error occurs when I try -
if(carName == Glendale)
I get error
C:\Users\Keiren\Desktop\Used\Games\GTA San Andreas\samp\gamemodes\aussieroleplay2.pwn(535) : error 033: array must be indexed (variable "carName")

Re: [CODE] if statements with strings - help please - DR3AD - 05.04.2012

Man, I understand what you trying to do.. in other languages that would work a think, at least some of it

Код:

format(Bravura, sizeof(Bravura), "Bravura");
format(Glendable, sizeof(Glendale), "Glendale");    // this instead the "=" operator to give them a value

Then you have to do the same thing for carName

Код:

format(carName, sizeof(carName), "%s", params);

And to compare the two, you use

Код:

strcmp(Glendale, carName, true);   //and not the "=="

Hope I helped you somehow

Re: [CODE] if statements with strings - squomp - 05.04.2012

yeah thanks but when I do -
if(strcmp(Glendale, carName, true));
CreateVehicle(401,1667.5986,-1887.8107,13.2885,89.9480,78,76,0);
if(strcmp(Bravura, carName, true));
CreateVehicle(401,1667.5986,-1887.8107,13.2885,89.9480,78,76,0);

the two get mixed up and Glendale creates bravura and Bravura creates Glendale so I then have to do -

if(strcmp(Bravura, carName, true));
CreateVehicle(466,1667.5986,-1887.8107,13.2885,89.9480,78,76,0);
if(strcmp(Glendale, carName, true));
CreateVehicle(401,1667.5986,-1887.8107,13.2885,89.9480,78,76,0);

Re: [CODE] if statements with strings - DR3AD - 05.04.2012

The strcmp() returns a value if the values match and another if they dont

Like this

Код:

 if(strcmp(Glendale, carName, true) == 0)
               // then you create a glendale
         else if(strcmp(Bravura, carName, true == 0)
              // then you create a bravura
         else
              // The car isnt a bravura or a glendale

You can see here when strcmp returns true https://sampwiki.blast.hk/wiki/Strcmp
"0" means that they are equal

you can't use two if's because it will do the two if's and thats not what you want
if it is a bravura, you can a piece of code, else if it is a glendale you run other piece of code and if it isn't a bravura or a glendale (the "else" part), then you can for example send a message saying "Invalid vehicle

Re: [CODE] if statements with strings - Harish - 05.04.2012

you used a static CarName[32];

static function will store the last used value ever..so try using new CarName[32];

and i had no idea where you placed that CarName = params;

Re: [CODE] if statements with strings - squomp - 05.04.2012

okay thanks for the help guys

Re: [CODE] if statements with strings - squomp - 05.04.2012

I see why it wasnt working its because I had to do - if(strcmp(Glendale, carName, true) == 0)

but i was doing - if(strcmp(Glendale, carName, true))
