Can anyone make this actor move automatically forward 60px and back 60px like super mario Heres the code: import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class GoldenBall here. * * @author (your name) * @version (a version number or a date) */ public class Lobster extends Actor { /** * Act - do whatever the GoldenBall wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { checkGoldenBall(); } public boolean canMove(int x, int y) { Actor sand; sand=getOneObjectAtOffset(x,y,sandroad.class); //the section below checks if there is a block you can move to // if there is it sets sand to a vlaue otherwise it says null // The errors are in this section boolean flag=false; if (sand !=null) { flag=true; } return flag; } /** * Check if Lobster eats the ball */ private void checkGoldenBall() { Actor GoldenBall= getOneIntersectingObject(GoldenBall.class); if (GoldenBall !=null ) { getWorld().removeObject(GoldenBall); } } }

So I spent a good amount of time on this (it's my first game), and was excited to find that you can run Greenfoot games on Android (with Droidfoot). However, my game does not seem to want to run on mobile devices. I receive heap-space memory errors after a few compilations on my PC, so I'm thinking it must be due to a memory issue in my game. Any pointers to help improve the games performance are greatly appreciated! http://www.greenfoot.org/scenarios/12530
