You have placed wrong numbers at strcmp.

if(!strcmp(cmdtext, "/skin ", true, 3)) <--- has 5 characters (with space), but there's only 3
if(!strcmp(cmdtext, "/skin 0", true, 3)) <--- wrong too...
if (strcmp("/skin 1", cmdtext, true, 10) == 0) <--- i think it's wrong too.

I suggest you to try to do one command within checking. Ex.:

Код:

  if(!strcmp(cmdtext, "/skin", true, 4))
  {
    if(cmdtext[3]==0) return SendClientMessage(playerid, 0xFF9900AA, "USAGE: /skin [skin id]");
    new skin[11];
    strmid(skin,cmdtext[5],0,11);
    if(!strcmp(skin,"0",true)) return SendClientMessage(playerid, 0xFF9900AA, "Invalid skin ID!"); // "0" for blank input, the problem is for cj skin
    new skinid = strval(skin);
    // check here for valid skin IDs...
    // and when set the skin if it's valid.
    SetPlayerSkin(playerid, skinid);
    return 1;
  }
