function is a set of operations that return a value. The value is obtrained by ether calculating it from the parameters passed to it, or by fetching the value from else where (such as from a database).

basically function is like a procedure (techincally procedure is a void function) that returns a value. Just like in math really

think of a function as the black box

you shove something in
and something else comes out

you can shove multiple things in, but only onething comes out

Ok thanks. One more question though. How does this part of my code relate to another if.


function collided (x1, x2, y1, y2, radius : int) : boolean
    for xCheck : x1 - radius .. x1 + radius
        if xCheck >= x2 - radius and xCheck = y2 - radius and yCheck
