I possible got it:

[pawn]if(strcmp("/carcolor", cmdtext, true, 10)== 0)[/pawn[

Notice that "10"? It checks if that's the string length. Just remove it.

Replace it by:

pawn Код:

if(strcmp("/carcolor", cmdtext, true)== 0)

So you'll get:

pawn Код:

if(strcmp("/carcolor", cmdtext, true)== 0)
  {
    if(!IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid, COLOR_BRIGHTRED, "You must be in a vehicle to use this command !");
    new tmp[4];
    tmp = strtok(cmdtext,idx);
    if(!strlen(tmp)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /carcolor [color1] [color2]");
    new color1 = strval(tmp);
    tmp = strtok(cmdtext,idx);
    if(!strlen(tmp)) return SendClientMessage(playerid, COLOR_WHITE, "USAGE: /carcolor [color1] [color2]");
    new color2 = strval(tmp);
    ChangeVehicleColor(GetPlayerVehicleID(playerid), color1, color2);
  return 1;
  }

Tip for saving time:

pawn Код:

if(strcmp(cmdtext,"/bla",true) == 0)

Checks if it compares.

pawn Код:

if(!strcmp(cmdtext,"/bla",true))

Does the same.
