Strmid - Incorrect Usage? - DrakeX - 01.07.2014

I changed:

pawn Код:

format(PlayerInformation[playerid][String], 64, "N/A");

to:

pawn Код:

strmid(PlayerInformation[playerid][String], "N/A", 0, 64);

And it doesn't seem to have an effect -- does strmid only work when copying strings?

Real helpful...

Anyways, for anyone wondering how I managed to fix this, I changed:

pawn Код:

strmid(PlayerInformation[playerid][String], "N/A", 0, 64);

to:

pawn Код:

strmid(PlayerInformation[playerid][String], "N/A", 0, strlen("N/A"), 64);

That method is very inefficient if I'm writing a long message, as the line is going to be huge.

An easier method can be this:

pawn Код:

new string[128];
strmid(string, "N/A", 0, sizeof(string), 128);

Correct me if im wrong.

Why would you want to use strmid anyway?

pawn Код:

format(PlayerInformation[playerid][String], 64, "N/A");

Is a lot easier in your case.

If you wanted to use strmid, it would need to be this:

pawn Код:

new string[126];
format(string, 126, "N/A");
strmid(PlayerInformation[playerid][String], string, 0, strlen(string), 126);

I'm sure you can tell the difference between the two - using strmid brings in unneeded lines and usage. Normally you would use strmid for something like this:

pawn Код:

new string[126];
format(string, 126, "%s", GetPlayersName(playerid));
strmid(PlayerInformation[playerid][Name], string, 0, strlen(string), 126);

Even then, you can use format, which in my opinion is a lot easier, because it would turn into:

pawn Код:

format(PlayerInformation[playerid][Name], 126, "%s", GetPlayersName(playerid));

I gave you a page that explains EXACTLY what strmid is used for, and why you SHOULDN'T be using it for this situation.

Don't! Format is slower - in fact, the best way to copy a string to another is memcpy or strcat (https://sampforum.blast.hk/showthread.php?tid=309130).
