IsPlayerConnected is useful for certain situations. It's not necessary in a script a script however because this:

pawn Код:

if( !IsPlayerConnected( playerid ) )

is basically the same as:

pawn Код:

if( playerid == INVALID_PLAYER_ID )

A example situation involving when checking a player is connected method is the code below (I just wrote it up for this post, this code is not tested)

pawn Код:

CMD:slap( playerid, params[ ] )
{
     static
          s_int
     ;
     if( sscanf( params, "r", s_int ) )
          return false;

     if( s_int == INVALID_PLAYER_ID )
          return false;
 
     static
          Float:s_pos[3]
     ;
     GetPlayerPos( s_int, s_pos[0], s_pos[1], s_pos[2] );
     SetPlayerPos( s_int, s_pos[0], s_pos[1], s_pos[2] + 10 );
     return true;      
}
