The Xs tell you where you've been and the arrows tell you how to get back. Walking the maze you might take some chalk, put an X in the middle of any room you visit and draw an arrow every time you go through a door. Oh, and if you get out of the rooms, you're done. 'backing up' is coming out of the recursive call. If you have tried all directions, back up one room and try another direction. If you can't go left, try another direction. If there's a door to your left and you haven't already been there, go left.

Think about how you'd tell a 5th grader to walk a maze of rooms. okay lets not visit again'ДЄlso on the internet there are alot of algorithsm to solve a maze quickly however I need to do it 'manually' so to speak, my mouse needs to explore the maze and then find the best path based on that information.Д¬ool discussion, hope you're having fun doing this! I would like it to say make intelligent steps by going 'have I been to teh cell on the right? yes. So far I've made it detect walls and walk the maze in a random fashion, which eventually solves teh maze, however extremely ineffeciently. This is using the greenfoot environment, all the calls to Mouse etc are super's and they (mouse class) can't be changed. List Brick = myWorld.getObjectsAt(x+2, y, Brick.class) List Brick = myWorld.getObjectsAt(x-2, y, Brick.class) List Brick = myWorld.getObjectsAt(x, y+2, Brick.class) List Brick = myWorld.getObjectsAt(x, y-2, Brick.class) TuxLeft = new GreenfootImage(getImage()) Import greenfoot.* // (World, Actor, GreenfootImage, and Greenfoot) I asssume I need to store in a 2d array all the co-ordinates and then assign them values related to say how many walls there are and the type of exits and how many times i've visted?

This section explains how to save created images in an appropriate format.Recursion as in backtracking? I understand the theory, however implementing it where I come undone. This section describes how to create an image and how to use the image itself as a drawing surface. This section teaches how to display images using the drawImage method of the Graphics and Graphics2D classes. This section explains how to load an image from an external image format into a Java application using the Image I/O API Drawing an image The basic operations with images are represented in the following sections: Reading/Loading an image Provides methods for accessing specific pixels within the image.Provides a mechanism for creating multiple subimages from a single image data buffer.Represents the rectangular coordinates of the image.The Raster performs the following functions: The ColorModel provides a color interpretation of the image's pixel data. A BufferedImage has a ColorModel and a Raster of image data. It is therefore more efficient to work directly with BufferedImage. Since BufferedImage is a subclass of Image it can be rendered by the Graphics and Graphics2D methods that accept an Image parameter.ДЄ BufferedImage is essentially an Image with an accessible data buffer. It manages the image in memory and provides methods for storing, interpreting, and obtaining pixel data. The BufferedImage class is a cornerstone of the Java 2D immediate-mode imaging API. Applications can directly construct instances of this class. class, which extends the Image class to allow the application to operate directly with image data (for example, retrieving or setting up the pixel color). class is the superclass that represents graphical images as rectangular arrays of pixels. The are two main classes that you must learn about to work with images: This lesson teaches you the basics of loading, displaying, and saving images. Saving the contents of a Java 2D image to an external GIF, PNG, or JPEG image file.Drawing the contents of a Java 2D image on to a drawing surface.Directly creating a Java 2D image and rendering to it.Loading an external GIF, PNG JPEG image format file into the internal image representation used by Java 2D.There are a number of common tasks when working with images. Images lesson, Images are described by a width and a height, measured in pixels, and have a coordinate system that is independent of the drawing surface.
