enums - Roai - 26.12.2013

i'm trying to work with enums but i have problem with those,

PHP код:



enum Pam

{

pamo[256],

};

enum Times

{

lMinute,

lHour,

sName[30],

paranum,

Pam:sParamater[30],

};

new Loop[MAX_LOOPS][Times];

Loop[0][sParamater.1] = " ";

Quote:

C:\Users\win7\Desktop\samp03x_svr_R1-2_win32\gamemodes\lvdm.pwn(41) : error 010: invalid function or declaration

41:

PHP код:



Loop[0][sParamater.1] = " ";

can someone explain to me how to use it right?

Re: enums - Patrick - 26.12.2013

In my understanding you want to reset the string stored inside that variable?

pawn Код:

Loop[0][sParamater.1] = '\0';

Re: enums - Konstantinos - 26.12.2013

Those are invalid:

pawn Код:

Pam:sParamater

and

pawn Код:

[sParamater.1]

You cannot use a 2D inside an enum either so the best solution for it is:

pawn Код:

enum Times 
{ 
    lMinute, 
    lHour, 
    sName[30], 
    paranum
}; 

new Loop[MAX_LOOPS][Times]; 
new Loop_sParamater[MAX_LOOPS][30][128]; // 256 is not needed, it'll be fine with lowered value.
    
// somewhere:
Loop_sParamater[0][1] = " ";

In case you want to reset the string as pds2k12 said:

pawn Код:

Loop_sParamater[0][1][0] = EOS;
// EOS or '\0'

The funny thing is you can actually stack enums

Thats actually valid code

pawn Код:

enum enum1 {
    var1,
    var2,
    array1[5]
}

enum enum2 {
    var3,
    var4,
    array2[enum1]
}

new Array[enum2];

main() {
    printf("%d", Array[var3]);
    printf("%d", Array[var4]);
    printf("%d", Array[array2][var1]);
    printf("%d", Array[array2][var2]);
    printf("%d", Array[array2][array1][0]);
}

But well there is no advantage at all with this

thanks a lot

Re: enums - Roai - 29.12.2013

another question - how do i take enum as a paramater?

AW: enums - Nero_3D - 29.12.2013

Since enums can't have two dimensions you have to trick it
We just multiply the last two values

pawn Код:

#define MAX_LOOPS 10

enum Pam
{
    pamo[256],
    firstpam[256]
}

#define idx(%0,%1,%2) (%2 + (%0 * %0:%1))

enum Times
{
    lMinute,
    lHour,
    sName[30],
    paranum,
    sParameter[idx(Pam, 50, Pam: 0)]
}
new Loop[MAX_LOOPS][Times];

main() {
    strcat(Loop[0][sParameter][idx(Pam, 25, pamo)], "Hello World", 256);
    strcat(Loop[0][sParameter][idx(Pam, 20, pamo)], "Hello World 2", 256);

    printf(Loop[0][sParameter][idx(Pam, 20, pamo)]);
    printf(Loop[0][sParameter][idx(Pam, 25, pamo)][4]);
}

Edit: Should be working now, it useses now a macro, should be easier
