how to get acces of the World class with an actor class

By schoki7, with 1 reply.
Replied to by danpost, almost 13 years ago:

To access a variable in your sub-class of World (not the World class, which is the super-class of the world where you placed the variable), You need to cast what is returned with 'getWorld()' to that which you named your sub-class of World. If your sub-class of world was named 'MyWorld', then: <Code Omitted>provided that the variable has public

Does anyone have a snake game?

By behappy2, with 3 replies.
Last reply by danpost, almost 13 years ago:

I have several demos for snakes. Click on my picture icon (the fractal image) and on the lower right you will see my Collections. Go to the 'Demos by danpost' collection and check out the 'Snake Tracks Demo' specifically; as that one eats food to grow. I would also suggest looking at the others for different ways for the body segments to play 'follow the leader'.

Programming error

By drewleighton, with 1 reply.
Replied to by Duta, almost 13 years ago:

If you get that error, then you've attempted to create a method that returns a value ...but you've never returned a value. For example: <Code Omitted> ^This would give an error, as you need to return a value. The method should be this: <Code Omitted> If you are creating a method with "void" return type, then it doesn't return a value, and so you do not need a return statement. You can put return statements in a method with "void" return type - this will

can somone tell me whats wrong with this code please.

Last reply by danpost, almost 13 years ago:

In order to work with List object, the List class must be imported into your class with <Code Omitted>However, this would be more to the point and not require importing java.util.List: <Code Omitted>Knowing where to go to find what methods are available is of the upmost importance. You do not neccessarily have to learn each method inside and out. Just knowing that there is a method that does a specific thing is enough, because then you just go back to the information on it and ut

Turn to Face

By SunnyD212, with no replies.

In my program, I have a frog (the player) that eats flys and a ladybug that patrols the area; if you touch the ladybug you loose. My ladybug moves at random in any direction as the program runs, however I don't know how to have my ladybug turn to face the direction it is moving. If it decides to run to the left, it will continue to face right. It will stay facing right no matter the direction it starts to move in. Can anyone help me turn this ladybug around?

help with creating flowchart for greenfoot robot

By lewis4lfc@gmail.com, with no replies.

Hi Guys I have created a Greenfoot robot for my university assignment as described below using the following code: import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class robot_1 here. * * @author (your name) * @version (a version number or a date) */ public class robot_1 extends Actor { /** * Act - do whatever the robot_1 wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { int x = getX(); int y = getY(); //setlocation(x + 1, y); if (Greenfoot.isKeyDown("f")) { move (4); } if (Greenfoot.isKeyDown("b")) { move (-4); } if (Greenfoot.isKeyDown("l")) { turn(-3); } if (Greenfoot.isKeyDown("r")) { turn (3); } } public boolean foundBomb() { Actor bomb = getOneObjectAtOffset(0, 0, bomb_1.class); if(bomb != null) { return true; } else { return false; } } } keys to control robot movement F=Foward, B=Backward, L=left & R=right & here is a video of my robot:http://www.youtube.com/watch?v=IuixdHDPD24 For this Assignment my task is to use Greenfoot, I have been provided with a scenario, as part of this scenario I will have to produce a routine which will control a robot, this robot will be able to navigate across the table & push the bomb by pushing it into the red brick square, The robot will carry the bomb and will be controlled via the keyboard using keys for different directions The bomb and robot is allowed to go through and out of the square in the basic solution only. Must use the scenario provided For the basic solution this must be done within the act() method within the robot class. This report will cover: • What I did throughout the whole assignment • Flow charts • Test plans Does anyone know how I am supposed to create a Flowchart for this Greenfoot robot Using flowchart software QSEE Superlite?, as I do not get how to create a flowchart following this document: http://www.sendspace.com/file/xk8iid thanks

I am getting lost in your code. You are using more fields than are neccessary; you have multiple places where the actor gets re-located; your variable naming is cryptic; and you have nothing really working in your code (animation does not seem to work; I could not say what half the 'if's are checking or what their block do; you have some code that could be simplified and some variables that are useless -- count and conti). You may want to start fresh. Maybe create another sub-class of Actor called 'Mario' (with a capital M) and built it up; each time you add something, make sure it works be
