[libGDX] Error with Actor

Newbie & Debugging Questions
#1

Hey,

I’m trying to figure out how to use actors now and due to google not giving me any good tutorials except for this github code ( https://github.com/minimaldevelop/libgdx-scene2d-demo-game/blob/master/Libgdx-Scene2d-Game/src/com/minimaldevelop/libgdxgame/actors/FallingMan.java ) I’ve had to guess most of this.

The error I’m getting is…

Exception in thread "LWJGL Application" java.lang.NullPointerException
	at screens.Screen_Game2.render(Screen_Game2.java:83)
	at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:204)
	at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:112)

…which doesn’t tell me anythingother than that there is something wrong somewhere in the code below.

package actors;

import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.physics.box2d.Body;
import com.badlogic.gdx.scenes.scene2d.Actor;

import core.Core_Resources;

public class Player extends Actor
{
	private Body actorBody;
	private int keyFrameTimer = 0;
	private int keyFrame = 0;
	private int direction = 0; // Down(0), Left(1), Right(2), Up(3), Down-Left(4), Down-Right(5), Up-Left(6), Up-Right(7)
	
	public Player()
	{
		setX(20);
		setY(20);
	}
	
	public void draw(SpriteBatch batch)
	{
		setPosition(actorBody.getPosition().x, actorBody.getPosition().y);
		
		keyFrameTimer++;
		
		if(keyFrameTimer >= 30)
		{
			batch.draw(Core_Resources.entities[0][direction][keyFrame], getX(), getY(), Core_Resources.entities[0][direction][keyFrame].getWidth(), Core_Resources.entities[0][direction][keyFrame].getHeight());
			keyFrameTimer = 0;
		}
	}
}

Can anyone see what I’m doing wrong in this?

Here is the main class in case that somehow has anything to do with it:

package screens;

import actors.Player;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Input.Keys;

import com.badlogic.gdx.maps.tiled.TiledMap;
import com.badlogic.gdx.maps.tiled.TiledMapRenderer;
import com.badlogic.gdx.maps.tiled.TmxMapLoader;
import com.badlogic.gdx.maps.tiled.renderers.OrthogonalTiledMapRenderer;

public class Screen_Game2 implements ApplicationListener
{
	private TiledMap map;
	private TiledMapRenderer renderer;
	private OrthographicCamera camera;
	private BitmapFont font;
	private SpriteBatch batch;
	private Player player;
	
	@Override
	public void create() 
	{		
		float w = Gdx.graphics.getWidth();
		float h = Gdx.graphics.getHeight();

		camera = new OrthographicCamera();
		camera.setToOrtho(false, (w/h) * 10, 10);
		
		//Set the starting view location. (0,0) is in the bottom left corner.
		camera.position.x = 0;
		camera.position.y = 125;
		
		camera.update();

		font = new BitmapFont();
		batch = new SpriteBatch();

		map = new TmxMapLoader().load("assets/Maps/Map_01.tmx");
		renderer = new OrthogonalTiledMapRenderer(map, 1f / 32f);
	}

	@Override
	public void render() 
	{
		//Sets the background color and then clears the screen.
		Gdx.graphics.getGL20().glClearColor(0f, 0f, 0f, 0f);
		Gdx.graphics.getGL20().glClear( GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT );
		
		//This will exit fullscreen mode.
		if(Gdx.input.isKeyPressed(Keys.ESCAPE))
		{
			System.exit(0);
		}
		//Movement Controls
		if(Gdx.input.isKeyPressed(Keys.LEFT) || Gdx.input.isKeyPressed(Keys.A))
		{
			camera.position.x -= 0.05;
		}
		if(Gdx.input.isKeyPressed(Keys.RIGHT) || Gdx.input.isKeyPressed(Keys.D))
		{

		}

		}
		if(Gdx.input.isKeyPressed(Keys.DOWN) || Gdx.input.isKeyPressed(Keys.S))
		{
			camera.position.y -= 0.05;
		}

		camera.update();
		renderer.setView(camera);
		renderer.render();
		batch.begin();
		font.draw(batch, "FPS: " + Gdx.graphics.getFramesPerSecond(), 10, 20); 
		player.draw(batch);
		batch.end();
	}

	@Override
	public void dispose () 
	{
		map.dispose();
		font.dispose();
		batch.dispose();
	}

	@Override
	public void pause() 
	{
		//Called just before dispose() on desktop.
	}

	@Override
	public void resize(int arg0, int arg1) 
	{
		//Called once after the create() method and every time the game screen is resized.
	}

	@Override
	public void resume() 
	{
		//Not used on desktop.
	}
