Having Problems With The Key Listener

Newbie & Debugging Questions

Man I spent hours scratching my head on this one. I have never had a problem with input before but I am kinda changing things up a little. Man I can’t wait to stop letting myself get these irritating errors.

This is where I added it to the canvas.

public Main()
	{
		initGame();
		
		JFrame frame = new JFrame(gameMain.getName());
		frame.setIconImage(gameMain.setLogo());
		Canvas canvas = new Canvas();
		canvas.setPreferredSize(gameMain.getScreenSize());
		
		InputListener input = new InputListener();
		canvas.addKeyListener(input);
		canvas.addMouseListener(input);
		
		frame.add(canvas);
		frame.pack();
		frame.setVisible(true);
		canvas.setVisible(true);
		canvas.requestFocus();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
		canvas.createBufferStrategy(2);
		buffer = canvas.getBufferStrategy();
	}

This is the simple code to move in my player class and I did import the inputlistener.

	
public void input()
	{
		InputListener input = new InputListener();

		if(input.getKey() == "w")
			dir(0,-1);	
		if(input.getKey() == "a")
			dir(0,1);
		if(input.getKey() == "s")
			dir(-1,0);
		if(input.getKey() == "d")
			dir(1,0);
	}

Here is the InputListener class.

package com.base.engine;

import java.awt.Dimension;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;

public class InputListener implements KeyListener, MouseListener, MouseMotionListener
{
	Dimension mousePos;
	boolean clicked = false;
	boolean keyDown;
	boolean keyUp;
	String key;
	String tempKey;
	

	public Dimension mouseLoc()
	{
		return mousePos;
	}

	public void mouseMoved(MouseEvent e) 
	{
		mousePos = new Dimension(e.getX(), e.getY());
	}

	public void mousePressed(MouseEvent e) 
	{
		clicked = true;
	}

	public void mouseReleased(MouseEvent e) 
	{
		clicked = false;
	}

	public void keyPressed(KeyEvent e) 
	{
		keys(e.getKeyCode());
		keyDown = true;
	}

	public void keyReleased(KeyEvent e) 
	{
		keyDown = false;
	}

	public void keyTyped(KeyEvent e) 
	{

	}
	
	public void keys(int i)
	{
		if(i == KeyEvent.VK_A)
			key = "a";
		if(i == KeyEvent.VK_B)
			key = "b";
		if(i == KeyEvent.VK_C)
			key = "c";
		if(i == KeyEvent.VK_D)
			key = "d";
		if(i == KeyEvent.VK_E)
			key = "e";
		if(i == KeyEvent.VK_F)
			key = "f";
		if(i == KeyEvent.VK_G)
			key = "g";
		if(i == KeyEvent.VK_H)
			key = "h";
		if(i == KeyEvent.VK_I)
			key = "i";
		if(i == KeyEvent.VK_J)
			key = "j";
		if(i == KeyEvent.VK_K)
			key = "k";
		if(i == KeyEvent.VK_L)
			key = "l";
		if(i == KeyEvent.VK_M)
			key = "m";
		if(i == KeyEvent.VK_N)
			key = "n";
		if(i == KeyEvent.VK_O)
			key = "o";
		if(i == KeyEvent.VK_P)
			key = "p";
		if(i == KeyEvent.VK_Q)
			key = "q";
		if(i == KeyEvent.VK_R)
			key = "r";
		if(i == KeyEvent.VK_S)
			key = "s";
		if(i == KeyEvent.VK_T)
			key = "t";
		if(i == KeyEvent.VK_U)
			key = "u";
		if(i == KeyEvent.VK_V)
			key = "v";
		if(i == KeyEvent.VK_W)
			key = "w";
		if(i == KeyEvent.VK_X)
			key = "x";
		if(i == KeyEvent.VK_Y)
			key = "y";
		if(i == KeyEvent.VK_Z)
			key = "z";
	}
	
	
	public String getKey()
	{
		
		return key;
	}
	
	public boolean getKeyPress()
	{
		return keyDown;
	}

	@Override
	public void mouseDragged(MouseEvent e) {}
	@Override
	public void mouseClicked(MouseEvent e) {}
	@Override
	public void mouseEntered(MouseEvent e) {}
	@Override
	public void mouseExited(MouseEvent e) {}
}
