我在 APCS 中,我必须扩展 critter 类,这将使 critter 随机选择网格中的任何演员,然后移动到它的位置;从而“跟随”它。我的老师给了我们开始的类和方法名,不能改变。这是无法更改的跑步者。

import java.awt.Color;

import info.gridworld.actor.Rock;
import info.gridworld.actor.Actor;
import info.gridworld.actor.Flower;
import info.gridworld.actor.Bug;
import info.gridworld.grid.Location;
import info.gridworld.grid.BoundedGrid;
import info.gridworld.actor.ActorWorld;

public class AnnoyingCritterRunner
{
 public static void main(String[] args)
 {
  ActorWorld world = new ActorWorld(new BoundedGrid<Actor>(8,8));
  world.add(new Location(1, 1), new AnnoyingCritter());
  world.add(new Location(3, 1), new Rock());
  world.add(new Location(5, 2), new Actor());
  world.add(new Location(7, 6), new Flower());
  world.add(new Location(6, 6), new Actor());
  world.add(new Location(0, 5), new Actor());
  world.add(new Location(2, 6), new Bug(Color.GREEN));
  world.add(new Location(3, 5), new Actor());
  world.show();
 }
}

AnnoyingCritter 类必须包含小动物找到其“最好的朋友”和“关注它”所需的所有方法。

import info.gridworld.actor.Actor;
import info.gridworld.actor.Critter;
import info.gridworld.grid.Location;
import java.awt.Color;

import java.util.ArrayList;

public class AnnoyingCritter extends Critter
{
 /* instance variables will be needed
  * one for the bFF and one to set whether this Critter has a bFF (a boolean)
  */

  public AnnoyingCritter()
  {
    /* make an AnnoyingCritter constructor that sets a color and starts with the 
  * boolean variable above being "false"
  */
    Critter AnnoyingCritter = new Critter();
    AnnoyingCritter.setColor(Color.green);

  }

  private void pickBFF()
 {
    /* you'll need the grid, occupied locations, and some randomness to pick a friend
    */

 }

 public void processActors( ArrayList<Actor> actors)
 {
   /* this can be simple or complicated.  the idea is to pick a BFF if 
    * one is needed
    */
  if( !hasFriend )
  {

  }
//and it eats flowers and rocks
  for( Actor dude : actors )
  {

  }
 }

 public Location selectMoveLocation( ArrayList<Location> locs )
 {
  //you need a Grid

   //you need a location

  //you need to know where to go and if it's clear to move and then go there

 }
}

AnnoyingCritter 必须移动到它随机选择的演员的位置并吃掉挡路的鲜花和岩石。它还需要一次一个空间地移动到演员的位置。我不知道如何让烦人的小动物找到演员的位置,然后随机找到一个。进口也不能改变。

请帮忙,因为我已经坚持了几个小时。

Location 类有一些强大的方法。尝试这个:

int direction=getLocation().getDirectionToward(BFF.getLocation);
moveTo(getLocation().getAdjacentLocation(direction));

这应该一次将您移向 BFF 一个空间。

要找到 BFF:

Grid<Actor> grid=getGrid();
ArrayList<Location> locList=grid.getOccupiedLocations();
BFF=grid.get(locList.get(0));

只要确保 locList(0) 不是你自己的生物。

尝试阅读快速参考指南。

我很确定您必须使用 getLocation() 来查找演员的位置。或者...您可以使用循环并为列和行选择随机数,直到找到演员。开枪,这听起来是个好主意。我要试试。
