POMaze solver looping issue java
text
Body
copied!<p>So basically what I'm trying to do is creating a maze solving algorithm with the left hand rule but I'm encountering an issue that I can't seem to get passed. </p> <p>The first two codes are the ones I'm working with and the problem I'm having is that when I try to loop the if-statements it just continues to draw a straight line up instead of turning left (in this case) and THEN looping back to the beginning and drawing a line until it hits a wall again. Note that I'm aware that this aint the finished product, I just want to make sure that alteast the first left turn and the loop works correctly.</p> <pre><code>import se.lth.cs.ptdc.window.SimpleWindow; import se.lth.cs.ptdc.maze.*; public class MazeTurtle extends Turtle { protected int Maze; public MazeTurtle(SimpleWindow w, int x, int y) { super(w, x, y); } public void walk(Maze maze) { Maze m = new Maze(1); Turtle t = new Turtle(w, m.getXEntry(), m.getYEntry()); t.penDown(); while(true){ if(m.wallAtLeft(getDirection(), getX(), getY())){ t.forward(1); } if(m.wallAtLeft(getDirection(), getX(), getY())){ t.left(90); } /** The "wallInFront" could be ignored for now */ if(m.wallInFront(getDirection(), getX(), getY())) { t.left(-90); } if(m.wallInFront(getDirection(), getX(), getY())){ t.forward(1); } SimpleWindow.delay(10); } } } </code></pre> <p>Here is the the "Test" which tries to solve the maze with the given algorithm:</p> <pre><code>import se.lth.cs.ptdc.window.SimpleWindow; import se.lth.cs.ptdc.maze.*; public class MazeTest { public static void main(String args[]) { Maze m = new Maze(1); SimpleWindow w = new SimpleWindow(600, 600, "MazeTest"); MazeTurtle t = new MazeTurtle(w, m.getXEntry(), m.getYEntry()); t.penDown(); m.draw(w); t.walk(m); } } </code></pre> <p>Here is the maze class which i'm reffering to: <a href="http://pastebin.com/gxSeEc2U" rel="nofollow">http://pastebin.com/gxSeEc2U</a></p> <p>And the turtle class that I'm using: <a href="http://pastebin.com/0RqbVudn" rel="nofollow">http://pastebin.com/0RqbVudn</a></p>
