We have the snake eating the apple; however, there aren't any consequences to this. As a part of the game, we need to make the snake increase the length of his body for each apple he eats. Our requirements for this are as follows:
Add a body part to the snake when it eats an apple
As the snake moves, the body parts should follow
There will be multiple body parts
First, let's create a class that will contain the length of the snake's body. This can take the form of an inner class for now:
private class BodyPart {
private int x, y;
private Texture texture;
public BodyPart(Texture texture) {
this.texture = texture;
}
public void updateBodyPosition(int x, int y) {
this.x = x;
this.y = y;
}
public void draw(Batch batch) {
if (!(x == snakeX && y == snakeY)) batch.draw(texture, x, y);
}
}As you can see, it contains the x and y components...
