POMove Point - Centroid
text
Body
copied!<p>The purpose of the method is to take in a Point (c), then move the current centroid (x,y) to the new coordinated provided. This is done through finding the difference of the two and then translating the point to the new coordinate. However, I do not know how to set the new centroid value since I am setting the methods as voids.... Any ideas? Sorry for all of the code, tried to put as little as possible. Translate takes the point(x,y) and adds the values given (dx,dy).</p> <pre><code>private Point centroid; Triangle(Point a, Point b, Point c) { this.a = a; this.b = b; this.c = c; triPoints = new Point[] { a, b, c }; } public Point getCentroid() { Point centroid; double x = 0.0; double y = 0.0; x = (a.getX() + b.getX() + c.getX()) / 3; y = (a.getY() + b.getY() + c.getY()) / 3; centroid = new Point(x, y); return centroid; } public void move(double dx, double dy) { centroid = getCentroid(); System.out.println(centroid.getX() + " "+ centroid.getY()); centroid = centroid.translate(dx, dy); Point newCentroid = new Point(centroid.getX(),centroid.getY()); System.out.println(newCentroid.getX() + " "+ newCentroid.getY()); if(getCentroid().equals(newCentroid)){ }else{ } for (int index = 0; index < triPoints.length - 1; index++) { triPoints[index].translate(dx, dy); } } public void move(Point c) { double firstx = 0.0; double firsty = 0.0; Point f = getCentroid(); System.out.println(f.getX()+ " "+ f.getY() + " "+ c.getX()+ " "+ c.getY()); if (f.getX() >= c.getX()) { firstx = c.getX() - f.getX();} else{ firstx = Math.abs(f.getX() - c.getX()); } if (f.getY()>= c.getY()){ firsty = c.getY() - f.getY(); } else { firsty = Math.abs(f.getY() -c.getY()); } move(firstx, firsty); //System.out.println(centroid.getX() + " " + centroid.getY()); } </code></pre>
