我在APCS,我必须对生物类进行扩展,使生物随机选择网格中的任何角色,然后移动到其位置;从而“跟随”它。我的老师给了我们开头的课程名称和方法名称,以便不能更改。这是不能改变的跑步者。AnnoyingCritter GridWorld案例研究
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();
}
}
的AnnoyingCritter类必须包含所有找到的“最好的朋友”和“顺藤摸瓜”所需的小动物的方法。
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
}
}
这个恼人的罪犯必须移动到它随机选择的演员的位置,并吃掉那些在路上的花和岩石。它还需要一次移动到一个空间的演员位置。我无法弄清楚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,因为我一直坚持了几个小时。
