Create a new sub-class of the Animal class, called Hunter. These are the requirements for the hunter: Find a picture online that you would like to use for your hunter. Ensure that you shrink the picture enough that your hunter is appropriately sized. Add controls to the hunter that allow him to move in all four directions. When he turns left or right I want him to turn by 7 degrees, when you press back I want him to walk backwards. Ensure that the hunter doesn't run into any of the trees (if he does, he will turn 180 degrees). Ensure that the hunter doesn't walk off the edge of the world. Create a new sub-class of the Animal class called Predator. These are the requirements for the hunter: Find a picture online that you would like to use for your predator (bear, mountain lion, etc.). Ensure that you shrink the picture enough that your hunter is appropriately sized. Add random movement to your predator. Ensure that the predator doesn't run into any of the trees (if he does, he will turn 17 degrees). Ensure that the predator doesn't walk off the edge of the world. If you predator "sees" your hunter, then he will eat your hunter, play an appropriate sound, and the game is over.

Sorry. We do not do projects or assignments. We mainly help fix pre-existing code. If you have a specific problem while attempting to create code for your project or assignment, we can help. However, you should post the attempted code and explain what it does (in detail) and how that is different from what you want it to do. Use the 'code' link below the reply box to insert any codes into your posts.

import greenfoot.*; /** * Write a description of class Hunter here. * * @author (your name) * @version (a version number or a date) */ public class Hunter extends Actor { /** * Act - do whatever the Hunter wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { move(17); turnAtEdge(); moveWithArrows(); } /** * * */ public void moveWithArrows() { if(Greenfoot.isKeyDown("right")) { turn(7); } if(Greenfoot.isKeyDown("left")) { turn(-7); } if(Greenfoot.isKeyDown("down")) { turn(-7); } } /** * * */ public void turnAtTree() { if(Can.seeTree) turn(180); } /** * turning at worlds edge * */ public void turnAtEdge() { move(180); } } this is what i have so far what am i doing wrong

this code is making my character move irregularly and not smooth and when it hit the world it clings onto the edge as im pushing the arrow for it to move

It sure seems strange that a method that is named 'turnAtEdge' is moving the object instead of turning it. Also '17' is awfully quick for an actor to be moving (see first line in act method). Also seems silly to have two different 'if' conditions do the same action (see "left" and "down" key detection blocks).
