Open Question: How can I tell if he's attracted to me?

there’s this country club i go to and there my friends and i met a new group of people

so there’s this one guy i’m interested in… we got to know each other and we talk a lot and we teamed up in a game and he took silly pictures of me and bought me a beer, asks me about my day, makes fun of me a little sometimes, and one day while I was fixing my hair in the mirror he was like «you look good»… he has the potential of being interested but at the same time i’m thinking it’s just him being a very friendly and nice guy.

we talked and made plans to do things and even travel and he keeps telling me he’ll call me or that he’ll text me, but he never even asked for my number. And he’d do things like sit on the armrest of my chair or he’d beckon me to sit beside him, except it could all be interpreted as friendliness

I don’t know what else to do. how can I spark his interest? i don’t want to be friendzoned by this guy, but I can’t tell if he’s attracted or not
