Code:
public cmd_hp(id, level, cid)
{
     if (!cmd_access(id, level, cid, 3))
        return PLUGIN_HANDLED

     new Arg1[24]
     new Arg2[4]

     //Get the command arguments from the console
     read_argv(1, Arg1, 23)
     read_argv(2, Arg2, 3)

     //Convert the health from a string to a number
     new Health = str_to_num(Arg2)

     //Is the first character the @ symbol?
     if (Arg1[0] == '@')
     {
          new Team = 0
          //Check which team was specified.
          //Note that we start from [1], this is okay
          // it just means the @ isn't included
          if (equali(Arg1[1], "CT"))
          {
               Team = 2
          } else if (equali(Arg1[1], "T")) {
               Team = 1
          }
          new players[32], num
          //This function will fill the players[32] variable
          // with valid player ids.  num will contain the number
          // of players that are valid.
          get_players(players, num)
          new i
          for (i=0; i<num; i++)
          {
               if (!Team)
               {
                    //Set this player's health
                    set_user_health(players[i], Health)
               } else {
                    if (get_user_team(players[i]) == Team)
                    {
                         set_user_health(players[i], Health)
                    }
               }
          }
     } else {
          //finds a player id that matches the partial name given
          //the 1 means that it will not target the player if he
          // has immunity access
          new player = cmd_target(id, Arg1, 1)
         if (!player)
          {
               //this will print a message to the user who tried the command
               //The format for this command is called "format()" style,
               // where the first string formats the message according
               // to any number of following parameters.
               //  %s means a string
               //  %d or %i means an integer
               //  %f means a float
               // so "Hello %s, I am %d years old" will 
               //  require a string and integer to follow
               console_print(id, "Sorry, player %s could not be found or targetted!", Arg1)
               return PLUGIN_HANDLED
          } else {
               set_user_health(player, Health)
          }
     }

     return PLUGIN_HANDLED
}
okay i just looked in the DOC tutorial section on amxmodx.org and i don't understand one command...

in the code:

new player = cmd_target(id, Arg1, 1)
if (!player)

what is "!player" means?

why is the "!" mark is infront of player? what function does it gives player?
