在一个函数中将非全局变量用于单独的函数（Javascript）

Question

I've been trying to use the "rx" and "ry" variables in a seperate function ( http://i.stack.imgur.com/tV8ln.png ) And I cant figure out how to do it, I've tried using rx and ry as parameters for calling the function and even the function itself but It hasn't worked. And I am unable to make it a global variable because it requires many others leading up to it. Ive looked up how to do it and nothing has worked, so I thought I would ask here because there are many experienced coders on here that probably know how and I'm just a noob,

Here's the raw paste, If anyone can help me solve this It would be greatly appreciated :) http://pastebin.com/UWY8QKbW

Pass them in:

PlayerCell.prototype.borderCheck = function(rx, ry) {

And call appropriately:

this.borderCheck(rx, ry);
