Here all three commands are in dcmd:

put under OnPlayerCommandText

Код:

{
     dcmd(x, 1, cmdtext);
     dcmd(y, 1, cmdtext);
     dcmd(z, 1, cmdtext);
}

dcmd_x(playerid, params[])
{
     new
          Float:x,
          Float:y,
          Float:z;
     if(!strlen(params))
       return SendClientMessage(playerid, 0xFFFF00FF, "USAGE: \"/x [positive or negative float]\"");
     GetPlayerPos(playerid, x, y, z);
     SetPlayerPos(playerid, x+params, y, z);
     return true;
}

dcmd_y(playerid, params[])
{
     new
          Float:x,
          Float:y,
          Float:z;
     if(!strlen(params))
       return SendClientMessage(playerid, 0xFFFF00FF, "USAGE: \"/y [positive or negative float]\"");
     GetPlayerPos(playerid, x, y, z);
     SetPlayerPos(playerid, x, y+params, z);
     return true;
}

dcmd_z(playerid, params[])
{
     new
          Float:x,
          Float:y,
          Float:z;
     if(!strlen(params))
       return SendClientMessage(playerid, 0xFFFF00FF, "USAGE: \"/z [positive or negative float]\"");
     GetPlayerPos(playerid, x, y, z);
     SetPlayerPos(playerid, x, y, z+params);
     return true;
}

Should work.
