Lol damn! I don't know strcmp well! I use ZCMD!

I'll try it! You need more than 1 command, 'cause there are more than 1 fightingstyle:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    new cmd[30];
    new idx;
    cmd = strtok(cmdtext, idx);
    
   if(strcmp(cmd, "/boxingstyle", true) == 0)
   {
   new tmp[30];
   tmp = strtok(cmdtext, idx);
   new otherplayer = strval(tmp);

   if(IsPlayerConnected(otherplayer))
   {
        SetPlayerFightingStyle (playerid, FIGHT_STYLE_BOXING);
        SendClientMessage(playerid, COLOR, "You've successfully set a player's fightingstyle to boxing!");
   }
   return 1;
}
    return 0;
}

Tell me, if it worked or not! If yes, just copy this command, change it's name and set the fightingstyles different! Here you can find all of them:
