pues quisiera saber si se puede hacer un macro de params[] (como los params que utiliza dcmd)
public OnPlayerCommandText(playerid, cmdtext[])
{
new cmd[20], params[80];
sscanf(cmdtext, "ss", cmd, params);
//...
return 0;
}
public OnPlayerCommandText(playerid, cmdtext[])
{
new idx, cmd[20], params[80];
cmd = strtok(cmdtext, idx);
params = strtok(cmdtext, index);
//...
return 0;
}
Si lo quieres en OnPlayerCommandText:
Sscanf pawn Код:

pero no quiero usar sscanf, ni ningun procesador (ya que estoy creando uno y necesito saber como es esto) entonces esos params me daran los datos asi? ejemplo params[0] params[1] params[2]?
saludos |
/*----------------------------------------------------------------------------*-
Function:
sscanf
Params:
string[] - String to extract parameters from.
format[] - Parameter types to get.
{Float,_}:... - Data return variables.
Return:
0 - Successful, not 0 - fail.
Notes:
A fail is either insufficient variables to store the data or insufficient
data for the format string - excess data is disgarded.
A string in the middle of the input data is extracted as a single word, a
string at the end of the data collects all remaining text.
The format codes are:
c - A character.
d, i - An integer.
h, x - A hex number (e.g. a colour).
f - A float.
s - A string.
z - An optional string.
pX - An additional delimiter where X is another character.
'' - Encloses a litteral string to locate.
u - User, takes a name, part of a name or an id and returns the id if they're connected.
Now has IsNumeric integrated into the code.
Added additional delimiters in the form of all whitespace and an
optioanlly specified one in the format string.
