I think he likes me how do i get him?

i'm a freshman in college n i find this guy that i've seen around campus to be very attravtive. he usually works in the computer room n he would always look @ me n give me attitude when i saw him. on wednesday he was being more annoyin n sarcastic towards me bombarding me with questions n flirtin wit me so i have dis feeling that he likes me since he's very cute n has that player look i didnt want 2 give in becuz i wasnt sure so i kinda played hard to get. then i left without givin a number or anything. so i want 2 no wat should my next move be since im interested?
