I'm quite sure of that. Anyway, I'm unable to do that before anyone shows me how to do it. I'm currently thinking about writing quests in XML as events but I probably won't do anything serious anytime soon (next week I'm away from my laptop, then I have to prepare for my exams and after that there are holidays...). But posting a tips (especially if anyone would post an example of code) makes me to think again about it
