strlen - dominik523 - 11.07.2013

Hey! I tried to add strlen to my command so users can't enter strings larger than 24 characters. This code won't work, and I have no idea why.

Код:

 
    if(sscanf(params, "s[24]", params)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /bizname [name]");
    if(strlen(params) > 24) return SendClientMessage(playerid, COLOR_GREY, "Maximum character limit is 24.");

Does anyone know what to add so it will work?

Basically s[24] makes sure that the string obtained will be at least 24 chars long, the rest is truncated. Change it to s[25] (in your string declaration aswell)

Swap the order.

where do I put params than? I mean what to use instead of sscanf to get string?

if(isnull(params)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /bizname [name]");
// rest..
