I made a dialog to change some defines

PHP Code:

//OnDialogResponse...case dialogid:
#undef VALUE
#define VALUE strval(inputtext) 


But when i use it example

PHP Code:

printf("VALUE = %d", VALUE); 


In this line i get error "Undefined Symbol inputtext"

and example

PHP Code:

for(new i=0; i<VALUE; i++) 


i get error "Undefined Symbol inputtext"

How to do it correctly?

Defines are constants that get changed compile time, you need to use variables for that.

Well, are you doing those things inside OnDialogResponse? Otherwise you don't have inputtext.

Yes

PHP Code:

//OnDialogResponse...case dialogid: 
#undef VALUE 
#define VALUE strval(inputtext)

I tried it..

PHP Code:

new VALUE = 25; 


complier crashes in this line

PHP Code:

new Info[MAX_PLAYERS][VALUE][ENUM];

Because compiler needs constants when initializing arrays, there is no memory allocation in pawn or dynamic array sizes.

Noway?

printf("VALUE = %d", VALUE);

pawn Code:

// ** INCLUDES

#include <a_samp>

// ** DEFINES

#define VALUE strval(inputtext)

// ** MAIN

main()
{
    print("Loaded \"blank.amx\".");

    OnDialogResponse(0, 0, 0, 0, "50");
}

// ** CALLBACKS

public OnGameModeInit()
{
    return 1;
}

public OnGameModeExit()
{
    return 1;
}

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    printf("%d", VALUE);
    return 1;
}

for(new i = 0; i < VALUE; i ++)

pawn Code:

// ** INCLUDES

#include <a_samp>

// ** DEFINES

#define VALUE strval(inputtext)

// ** MAIN

main()
{
    print("Loaded \"blank.amx\".");

    OnDialogResponse(0, 0, 0, 0, "50");
}

// ** CALLBACKS

public OnGameModeInit()
{
    return 1;
}

public OnGameModeExit()
{
    return 1;
}

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    for(new i = 0; i < VALUE; i ++)
    {
        printf("%d", i);
    }
    return 1;
}

All work.

new Info[MAX_PLAYERS][VALUE][ENUM];

Set it to the highest value being used.

Declaring dynamic arrays isn't supported by PAWN, you have to have a constant value. In this case you are relying on "strval", not a constant.

Defines are just text replacements, so you are actually doing this: (not valid)

pawn Code:

new Info[MAX_PLAYERS][strval(inputtext)][ENUM];

And in case you are using "VALUE" inside of OnDialogResponse, the error should not occur.
Also i guess its meaningless to declare a macro instead of a variable here because basically you want a better readable code and don't want to process "strval" again and again. In that case, variables are helpful not macros.

pawn Code:

new VALUE = strval(inpittext);

That's not what i mean't, but thanks!

Thanks Gammix for explanations!

Yeah, I see. The definition doesn't store values, so who knows what you were thinking. And the main post lacks of what you were trying to do.
