Friends at Uni

I’m in halls and lowkey my floor is kinda dry. I’ve tried lots to socialise with people and organise hangouts in the common room but always to no fruition. Everyone has their own groups and some people just outright refuse to acknowledge each other (I’m also with some of my mates on the floor who complain about it) I’m wondering is it just the first few days or am I better off making friends in clubs and classes. I’m a fairly sociable personality and it’s a first time encountering a dilemma like this so please I would appreciate any type of advice I could get. FYI, I floor hop a lot but I hate to impose a lot since they have started getting real close to each other.
