*You can find an example of the former being used in an InDesign like app in Design Patterns by the Gang of Four if you want further reference on how to set that up. Greenfoot will detect as many keys down as you put in your code. I don't make games for a living so I'm sure there are even better ways to do it. When the pivot point is no longer valid (the snake no longer has any parts that cross the pivot) I'd remove it from the array. If I was implementing it I'd use an array of pivot points that would tell the snake how to turn pieces of the snake as it traverses the board. As the snake moves you can just increment over the array and change the points to take into account the direction of movement and how far to move. The snake object could have an array (or better yet an ArrayList) that stores the coordinates of the blocks that make up a snake. It wouldn't be unreasonable to let the snake draw itself on the board* or at least store it's display information for the board to handle. If it detects a collision on between the snake and itself, the game would end. If it the game board detects a collision between the snake and food, it would move the food sprite to the next position and invoke Eat() on the snake object in play. Probably a better idea would be to move user input elsewhere and have the game board communicate state changes to the various sprites (snake, food, wall etc) including collision detection. It looks like you're trying to put a lot of sprite interaction logic in your snake class. I'm getting the feeling your question is more general than simple array handling. GetWorld().addObject ( new Food(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(400)) * Write a description of class Snake here.Īctor a = getOneIntersectingObject(Food.class) The class Snake: import greenfoot.* // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) * Constructor for objects of class WorldofSnake.ĪddObject ( new Food(), Greenfoot.getRandomNumber(600), Greenfoot.getRandomNumber(400)) The world: public class WorldofSnake extends World Got a new task in School to code the Snake Game from scratch and need to use a array to add a new Snake bodypart when the Snakehead eats food and at the beginning the Snake need to have 1 head and 2 bodyparts.and I have no idea how to do this.can someone out there help me on right direction.how to start? Here is my code so far:
