before we get to algorithm # 3 ( accelerate towards the mouse ) , we need to cover one more rather important aspect of working with vectors and the pvector object : the difference between using static functions and instance methods . forgetting about vectors for a moment , take a look at the following code : var x = 0 ... | here 's how we would write the static version of add ( ) : pvector.add = function ( v1 , v2 ) { var v3 = new pvector ( v1.x + v2.x , v1.y + v2.y ) ; return v3 ; } ; there are several differences here : we define the function directly on the object , not on its prototype we never access the this keyword inside the funct... | so.. how is static functions even useful ? |
