My Snake isn't Growing

Question about the task

Resolved

Somehow I was able to complete all the tasks, but my snake doesn't grow. I can't post my code because I've "completed" the tasks. Does anyone know what could be causing the issue without seeing my code?

Probably in your public void move apple you forget to add the head to the snakeParts.

public void move(Apple apple) {
    GameObject head =  createNewHead();
    if(checkCollision(head)){
        isAlive = false;
    }
    else {
        if (head.x == apple.x && head.y == apple.y) {
            apple.isAlive = false;
            snakeParts.add(0, head);
        } else {
            if (head.x < 0 || head.y < 0 || head.x >= SnakeGame.WIDTH || head.y >= SnakeGame.HEIGHT) {
                isAlive = false;
            } else {
                snakeParts.add(0, head);
                removeTail();
            }
        }
    }
}

I had the same problem.. snake wasn't growing.. however my move(Apple) method was correct. The issues was in my draw(Game game) method... was missing the for loop changing the colour of each new non-body segment. So I was growing invisibly and then suddenly dying mid-game running into my invisible tail.

public void draw(Game game) {
        Color color;

        if (!isAlive) {
            color = Color.RED;
        } else color = Color.OLIVE;

        game.setCellValueEx(snakeParts.get(0).x, snakeParts.get(0).y, Color.NONE, HEAD_SIGN, color, 75);

        for (int i = 1; i < snakeParts.size(); i++) {
            game.setCellValueEx(snakeParts.get(i).x, snakeParts.get(i).y, Color.NONE, BODY_SIGN, color, 75);
        }
    }
