我正在尝试控制Bug
GridWorld 中的 s。我已经尝试了两种方法来做到这一点,但实际上都没有移动或改变错误。他们都编译但没有任何反应。
这是Bug
将被控制的:
package info.gridworld.actor;
import info.gridworld.grid.*;
import info.gridworld.grid.Location;
import java.awt.Color;
public class MazeBug extends Bug {
public MazeBug() {
super(Color.blue);
}
public void forward(){
Grid<Actor> gr = getGrid();
if (gr == null)
return;
Location loc = getLocation();
Location next = loc.getAdjacentLocation(getDirection());
if (gr.isValid(next))
moveTo(next);
else
removeSelfFromGrid();
}
public void turnRight(){
setDirection(getDirection() + Location.RIGHT);
}
public void turnLeft(){
setDirection(getDirection() + Location.LEFT);
}
}
这是我尝试使用 Scanner 使用键 W、A 和 D 控制错误的第一种方法(不确定我是否正确使用了扫描仪)
package info.gridworld.actor;
import java.util.Scanner;
import info.gridworld.grid.*;
public class KeyTests extends Actor
{
public static ActorWorld world = new ActorWorld(new BoundedGrid<Actor>(20, 20));
public static MazeBug currentBug;
public static void main(String[] args) {
world.show();
world.add(new Location(1,11),new MazeBug());
while(true){
Scanner k = new Scanner(System.in);
String buttonpress = k.nextLine();
if (buttonpress.equals("w"))
currentBug.forward();
if (buttonpress.equals("d"))
currentBug.turnRight();
if (buttonpress.equals("a"))
currentBug.turnLeft();
}
}
}
这是我尝试控制错误的第二种方法
package info.gridworld.actor;
import info.gridworld.grid.*;
public class KeyTests extends Actor
{
public static ActorWorld world = new ActorWorld(new BoundedGrid<Actor>(20, 20));
public static MazeBug currentBug;
public static void main(String[] args) {
world.add(new Location(1,11),new MazeBug());
java.awt.KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new java.awt.KeyEventDispatcher() {
public boolean dispatchKeyEvent(java.awt.event.KeyEvent event) {
String key = javax.swing.KeyStroke.getKeyStrokeForEvent(event).toString();
if (key.equals("w"))
currentBug.forward();
if (key.equals("d"))
currentBug.turnRight();
if (key.equals("a"))
currentBug.turnLeft();
world.show();
return true;
}
});
world.show();
}
}
