So this codeA:

public FiringCommandGroup extends CommandGroup {

     public FiringCommandGroup() {
          addSequential(new FireCommand1());
          addSeqiential(new waitCommand(1));
          addSequential(new FireCommand2());
     }
}

...is quite different than this codeB:

public void execute() {
     if (timeSinceInitialized() < sometime) {
          do something;
     } else if(timeSinceInitialized() < some bigger time) {
          do nothing;
     } else {
          do something2;
     }
}

...because codeA executes FireCommand1() once, then waits, then executes FireCommand2() once, and exits.

whereas codeB executes "something" repeatedly, then waits, then executes "something2" repeatedly.

Yes?
