我想在GridWorld中控制Bug
。我已經嘗試了兩種方法來做到這一點,這兩種方法都沒有實際移動或轉換錯誤。他們都編譯但沒有任何反應。Gridworld中的事件監聽器/掃描器
這裏是一個將被控制在Bug
:
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);
}
}
這裏是我嘗試使用掃描儀控制與鍵W,A,和d的bug(不知道我是否正確使用掃描儀的第一種方式)
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();
}
}
}
這裏是第二個辦法,我試圖控制錯誤
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();
}
}
感謝您的任何幫助先進的
