the class VoronoiGrid method paintComponent.

public void paintComponent(Graphics go) {
    Graphics2D g = (Graphics2D) go;

        for (int x = 0; x < d.getWidth(); x += cellSize) {
            nCells++;
            int closestIndex = getClosestPointIndex(new Vector2d(x, y));
            g.setColor(colors.get(closestIndex));
            g.fillRect(x, y, cellSize, cellSize);
        }
    // System.out.println(y);
    }
    System.out.println("Painted n cells: " + nCells);
    System.out.println(timer);
// if (!dimension.equals(d) || )
}

Example 2 with Vector2d

use of math.Vector2d in project SimpleAsteroids by ljialin.

the class MonkeyBall method update.

@Override
public void update() {
    s.add(v);
    v.y += gravity;
    // now take account of the anchor
    if (anchor != null) {
        // introduce a tension force on the MonkeyBall towards the anchor
        Vector2d tension = new Vector2d(anchor);
        tension.subtract(s);
        tension.mul(hooke);
        v.add(tension);
    }
    v.mul(loss);
}

Example 3 with Vector2d

use of math.Vector2d in project SimpleAsteroids by ljialin.

the class RopeGameTestController method main.

public static void main(String[] args) throws Exception {
    // make a game state
    // make a view based on the state
    // figure out a way to update it
    // the idea is to provide a simple demo of the game
    RopeGameState gameState = new RopeGameState();
    RopeGameView view = new RopeGameView(gameState);
    JEasyFrame frame = new JEasyFrame(view, "Monkey Ball");
    Random random = new Random();
    // this is the delay per frame update, but also use it
    // as the basis of switching an anchor point on and off
    int delay = 40;
    Vector2d anchor = null;
    for (int i = 0; i < 5000; i++) {
        // // each time update
        // if ((i / 40) % 2 == 0) {
        // anchor = null;
        // } else {
        // // if it is null, make a new one at a Random location
        // // otherwise leave alone
        // int w = RopeGameState.width;
        // if (anchor == null) {
        // anchor = new Vector2d(w/4 + random.nextInt(w/2), w/5 + random.nextInt(w/3));
        // }
        // }
        gameState.update(view.anchor);
        view.repaint();
        Thread.sleep(delay);
    }
