For the smoke, i think there is an item that smokes, i guess you cut just make a command to "CreateObject" and a command to remove the Objects again, tho i'm not sure..

Код:

 	if (strcmp("/createo", cmdtext, true, 10) == 0)
 	{
 		if(IsPlayerAdmin(playerid))
 		{
			CreateObject(modelid, Float:X, Float:Y, Float:Z, Float:rX, Float:rY, Float:rZ);
 	  	}
 	  else
 	  {
		return 0;
		}
	}

something like this i guess.. Not sure tho
