Hey, I need some help with wall hugging(my question is here because I base my wall smoothing implementation on wall smoothing). I am using PEZ's wall smoothing code to hug walls. The only differences being that when I call the method I use getHeadingRadians() instead of absoluteBearing and I also removed -Math.PI/2*direction from the variable goalDirection. My problem here is not when it hug the walls clockwise(it hugs them perfectly), but when it tries reverse direction by going anticlockwise. It seizes up and oscillates between a few pixels. Thanks in advance --[[User:Khanguy|Khanguy]] 21:44, 10 April 2011 (UTC)

Hmm, kind of hard to say without seeing the code. My guesses would be your back-as-front method is messed up (you have right angle to move in but aren't moving that way correctly), you're not calculating current direction correctly, or you just lost some direction-sensitive piece of logic in your adaptation of the code. Can you draw (or even just print out) the angles that are being considered, like in [http://www.youtube.com/watch?v=SrbNxXiNp3k this YouTube video]? That should offer some clues. --[[User:Voidious|Voidious]] 02:01, 11 April 2011 (UTC)

Hey, I need some help with wall hugging(my question is here because I base my wall smoothing implementation on wall smoothing). I am using PEZ's wall smoothing code to hug walls. The only differences being that when I call the method I use getHeadingRadians() instead of absoluteBearing and I also removed -Math.PI/2*direction from the variable goalDirection. My problem here is not when it hug the walls clockwise(it hugs them perfectly), but when it tries reverse direction by going anticlockwise. It seizes up and oscillates between a few pixels.
