Ejemplo, ingresas el comando /sethealth 0 100, params serнa igual a "0 100", si lo usas asi, params[0] serнa el 0 y params[1] serнa el espacio que le sigue.
Acб es donde entra en juego strtok o sscanf, si no queres usar sscanf el plugin, hay una versiуn el cуdigo de sscanf, obviamente sigue siendo rбpida pero es menos ineficiente que el plugin que estб hecho en C++.

/*----------------------------------------------------------------------------*-
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.
