You are getting these errors because you have already defined X, Y and Z earlier in your script. Try this:

Код:

  if(strcmp(cmdtext, "/roadblock", true)==0)
  {
    	new Float:pX, Float:pY, Float:pZ, Float:pA;
    	GetPlayerPos(playerid, pX, pY, pZ);
    	GetPlayerFacingAngle(playerid, pA);
    	CreateObject(981, pX, pY, pZ, 0.0, 0.0, pA);
    	SendClientMessage(playerid, COLOR_GREEN, "RoadBlock Successfully Deployed");
  	return 1;
  }

X, Y and Z have been renamed to pX, pY and pZ. A has been changed to pA too just to match :P
