I created an Enum and some variables are arrays. When I try to reset these variables to "", I get an error.

pawn Код:

enum playerInfo
{
    var1[16],
    var2[145],
    var3[20];
}

new pInfo[MAX_PLAYERS][playerInfo];

//In some callback
pInfo[playerid][var1] = ""; //line 1093
pInfo[playerid][var2] = ""; //line 1094
pInfo[playerid][var3] = ""; //line 1095

pawn Код:

(1093) : error 047: array sizes do not match, or destination array is too small
(1094) : error 047: array sizes do not match, or destination array is too small
(1095) : error 047: array sizes do not match, or destination array is too small

This is a pawn entity

Use strcat instead, https://sampwiki.blast.hk/wiki/Strcat

pawn Код:

strcat(pInfo[playerid][var1], "");

Or: (dont know if it works, just an idea)

pawn Код:

pInfo[playerid][var1][0] = EOF;
//or
pInfo[playerid][var1][1] = EOF;

If you got some time, feel free to test it, would be interesting to know if it works, as this would be much faster than strcat.
Basically, EOF is a symbol that tells pawn that the string is over here. Every string has this at the end, this is why
new txt[32];
could save a maximum of 31 chars.

Wouldn't strcat just join a variable with ""?
Like, pInfo[playerid][var1] = "Hello";
Wouldn't strcat just make it "Hello "?
As for EOF, it turns the first character of the string into a я.

pawn Код:

pInfo[playerid][var1] = "test";

Even this gives me: error 047: array sizes do not match, or destination array is too small.

To store a string, I always use format:

pawn Код:

format(pInfo[playerid][var1], sizeof(pInfo[playerid][var1]), "test");

If you would print this string using:

pawn Код:

print(pInfo[playerid][var1]);

This would print: "test" (without the ").

To clear a string, I use 0:

pawn Код:

pInfo[playerid][var1] = 0;

Printing it again would print: "<null>" (without the ").

Thanks Mauzen and PowerPC603.
I still wonder though, why I can't use pInfo[playerid][var1] = ""; when I can do it on this variable.

pawn Код:

new msg[128];
msg = "Hello";
msg = "";

Oh ok, I will have to read some things again then.

@PowerPC603: Hm, never tried it with a 0


The problem why you cant use it like this:

pawn Код:

new msg[128];
msg = "Hello";
msg = "";

is caused by the way pawn handles strings.
A String is just a integer-array, with one int for each character. And if you use the normal '=' operator, pawn tries to write a string (array, e.g. "Hello", length 5) into another array (msg[128]). But as you can see, these both array do not have the same size, so you cant just set the on‌e=the other. This gives you the error then.

Actually you can use it like that. I've used it like that many times and it works and compiles fine with no errors. But I get what you're saying.
