Randy Hoyt's Robot Maze - Pt.2 - (!this.maze) always returns false.

I had an error in my code on the last line in "Maze.prototype.canMove" method (maze.js). The problem was that it was returning false after all the checks:

if (this.spaces[forwardX][forwardY][opposites[direction]]) { return false; } return false; }

This was preventing me from moving the robot forward at all - always alerting "No." no matter where the robot was placed within the maze.

I was able to trace it by doing a diff on my maze.js and the project files, but I'd like to gain a better understanding of the root of the problem before I wash my hands of this.

After changing the last statement within the "Maze.prototype.canMove" method to the following I was able to move forward... until...

if (this.spaces[forwardX][forwardY][opposites[direction]]) { return false; } return true; }

Until I got around to the space 5,3! And now I'm stuck because I've done a diff on both robot.js and maze.js and I have no differences...

I'm guessing it's as simple as doing another diff to verify my above work, and also run a diff on the maze interface, however I'd like to hear if anyone has any other ideas of how to go about debugging this...

I'm at the point where I put in a break point on the first line inside the "Robot.prototype.canMoveForward" (robot.js), but it is always returning false, even when I can move forward.. so I feel stuck.

Any suggestions would be greatly appreciated!
