thank you for your help !! I understood that with the plugins-de_dust.ini so far. but i think that will not solve my problem or my plan.
my thought is. I set the zombie plague so that it runs from 7 p.m. to 6 a.m. I would like that only dust2 is active at this time. no other map voted. and no other map is loaded from the mapcycle after 20 minutes.
the server should then be a standard counter strike server from 6 a.m. to 7 p.m.
That's why I think that I can't get any further with your idea.
