So at first only the first part of text will be shown, then player shoud press <space> and "...AN ORC!" will be appended to the same subtitle. Note, this is not two different subtitles, but just one shown part by part."I am not a real elf, i must say you i am an.... [extend] ...AN ORC!"
Is anything like that in DialogueSys out of the box? I would like it, to make dialogues more vivid. Or maybe some SequencerCommands could be used here? At least they pause the response menu until end.
