sscanf - Dr - 18.09.2011

How can I make sscanf see something that will make it understand it is separate?

Example:

A,B,C,D

How can I make sscanf recognize that the ',' is separating the letters?

Re: sscanf - Vince - 18.09.2011

Use the 'p' specifier:
pawn Код:
"p<,>cccc"


Re: sscanf - Dr - 18.09.2011

Okay and example how can I do this:

A,B,C,D | A,B,C,D

And make it recognize that one ABCD is different from another? With the p also?

pawn Код:
"p<|>ss"

Re: sscanf - Dr - 18.09.2011

No but I want it for example to separate each value with a ',' but then each line by a '|' or something similar, is that possible?

Re: sscanf - =WoR=Varth - 18.09.2011

Each line?

Re: sscanf - GrimR - 19.09.2011

The OP means A,B,C,D as a group of 4 single identifiers to be seperated
by (,) and then groups of identifiers to be seperated by (|).

Re: sscanf - Babul - 19.09.2011

just combine Vince's and =WoR=Varth's string:
Код:
"p<,>cccc"
parse the A,B,C,D, then search for the | using the single quotes ' '
Код:
"p<,>cccc'|'"
and finally parse the next... E,F,G,H ?
Код:
"p<,>cccc'|'cccc"

Umm but for example:

pawn Код:
#include <a_samp>

#define COLOR_BLUE 0x2641FEAA
#define COLOR_GREEN 0x33AA33AA
#define COLOR_RED 0xAA3333AA

The problem with that is, it doesn't load example one house string and then makes it work, it spawns the max houses, whether they are in "houses.cfg" or not and spawns them, how can I make it work, please help!

Re: sscanf - Babul - 20.09.2011

the quickest way to track any weird behavior down, it to get a lot of debug printed out. i added some SendClientMessageToAll inside the sscanf, and nested the sscanf into a if(). if an invalid line gets read, it will show you ingame what it contains.
and it seems that the file is closed too early. pay attention to the if(file)...

i cant test that out, so i did only easy stuff for debugging. its a good idea to backup all house files, and work with a "limited" version, like 3-4 houses only, all created by hand... good luck!
