I am using the Android Studio IDE, with the libGDX framework to develop a game. It is a clone of the Pac-Man game with a similar gameplay to flappy bird. The concept is that the pac man moves through the planks while avoiding the ghosts coming from the right direction, that are moving off straight into the left direction (not chasing the position of the player). I am not sure how I create a 'for loop' for the ghost animations, I want the ghosts to consistently reposition and re-appear from the right side after a few seconds, with the exception that they completely gone off the screen initially.
The class for one of the Ghosts.
public class Blinky {
private Vector3 position; //x y and z axis
private Rectangle bounds;
private Texture texture1;
private Animation blinkyAnimLeft;
public Blinky(int x, int y) {
position = new Vector3(x, y, 0);
Texture texture1 = new Texture("blinkyLeft.png");
blinkyAnimLeft = new Animation(new TextureRegion(texture1), 2, 0.5f);
//bounds = new Rectangle(x,y,texture1.getWidth() / 2, texture1.getHeight());
}
public void update(float dt) {
blinkyAnimLeft.update(dt);
//bounds.setPosition(position.x, position.y);
}
public Vector3 getPosition() {
return position;
}
public TextureRegion getTexture() {
return blinkyAnimLeft.getFrame();
}
//public Rectangle getBounds() {
return bounds;
}
public void dispose() {
texture1.dispose();
}
}
Ghosts and Player initialised in the GamePlayState Class
public class GamePlayState extends State {
//Variables
private float timePassed = 0;
private Texture background;
public static final int WALK = 1;
public static final double GHOST_WALK = 0.5;
private static final int PLANKS_SPACING = 125; //gap betwen the planks
private static final int PLANK_COUNT = 4;
private Array<Obstacle> planks;
private Player player;
private Blinky blinky;
private Inky inky;
private Texture missile;
public GamePlayState(GameStateManager gsm) {
super(gsm);
player = new Player(50, 100);
blinky = new Blinky(400, 220);
inky = new Inky(400, 240);
// missile = new Texture("missile.png");
background = new Texture("black.jpg");
cam.setToOrtho(false, PacMan.WIDTH/2, PacMan.HEIGHT/2);
planks = new Array<Obstacle>();
for (int i = 1; i<= PLANK_COUNT; i++) {
planks.add(new Obstacle(i * (PLANKS_SPACING + Obstacle.PLANK_WIDTH)));
}
}
#Override
public void handleInput() {
}
#Override
public void update(float dt) {
handleInput();
player.update(dt);
blinky.update(dt);
inky.update(dt);
cam.position.x = player.getPosition().x + 80; //update the position of the camera with the bird
//update when pacman cam viewport has passed plank
//make cam follow the player
for (Obstacle plank: planks) {
if (cam.position.x - (cam.viewportWidth/1) > plank.getPosTopPlank().x + plank.getTopPlank().getWidth()) {
plank.respositionPlanks(plank.getPosTopPlank().x + ((Obstacle.PLANK_WIDTH + PLANKS_SPACING * PLANK_COUNT )));
}
if (plank.collision (player.getBounds()))
gsm.set(new GamePlayState(gsm));
}
cam.update();
}
#Override
public void render(SpriteBatch sb) {
sb.setProjectionMatrix(cam.combined);
sb.begin();
sb.draw(background, cam.position.x - (cam.viewportWidth/2), 0);
timePassed += Gdx.graphics.getDeltaTime();
//Moving Inky
sb.draw(inky.getTexture(), inky.getPosition().x, inky.getPosition().y);
inky.getPosition().x -= GHOST_WALK;
//Moving Blinky
sb.draw(blinky.getTexture(), blinky.getPosition().x, blinky.getPosition().y);
blinky.getPosition().x -= GHOST_WALK;
You should get x, y( and z) position from Vector3.
Then check for borders
if (inky.getPosition().x < 0){
Thread.sleep(/*a few sdeconds*/2000);/*Android studio would ask you about wrapping it with try - catch*/
inky.setPostion( x + /*screen x size*/,
inky.getPosition().y,inky.getPosition().z)/*add setter in ghost class*/
}
In fact, this is not the best way to do it, but the simplest one

I'm new to android development and I'm having a problem regarding the memory used by my game. It constantly rises until it crashes. I would appreciate if you could help me. Thank you.
Also, regarding the Spritebatch do i need to call this.dispose in the java class where i extend to game for it to be disposed? If so where can i call it? Thank you

I'm reading between the lines, but it looks like you must be loading a Texture in the constructor of Bullet/Target/Explosion, since I don't see you passing a Texture or TextureRegion reference to their constructors or render methods.
You should be loading all your Textures in a single class and passing references to your game objects for them to "borrow" and draw with. Otherwise, you are loading many copies of the same images for no reason.
Also, a Texture is a Disposable, which means it uses native memory and must have dispose() called on it before you let the garbage collector take it. Otherwise, the native memory is leaked.
In your case, all these Bullets, Targets, and Explosions are loading many Textures over and over and never disposing them when you remove them.
Regarding your question about the SpriteBatch. Yes, you should dispose of it in the same class you instantiate it, and dispose() is the right place to do it.
Edit, barebones example:
public class Assets implements Disposable {
public final Texture horse;
public final Texture bullet;
// etc.
public Assets (){
horse = new Texture("horse.png");
//...
}
public void dispose(){
horse.dispose();
//...
}
}
public class Zero implements Screen, InputProcessor {
private final Assets assets;
//...
public Zero (){
assets = new Assets();
//...
}
//...
public void dispose(){
assets.dispose();
//...
}
}
public class Bullet {
//...
public void render(SpriteBatch batch, Assets assets){
batch.render(assets.bullet, /*...*/);
}
}
My sprite moves too slowly. Basically I want to apply less force to move my player. Current this:
getBody().applyForceToCenter(new Vector2(-10000000f,0f), true);
is the force needed to make it move a tiny bit.
I know the reason why I am not able to move it is since I haven't scaled the sprite (64x64) it weights more than 400kg. What should be the correct scale?

Could you please give me a fix?
I already tried to divide body and gamecam position still no effect
What should be the correct scale?
The right scale would be the scale in real life where 1 unit in LibGDX (Box2D) represents 1 meter in real life. I always advice people to use this scale and zoom the camera properly.
Mind though, if you are using very large objects and zoom the camera all the way back objects appear to be falling slowly. This is obviously because your camera contains a much larger space. Not only would it fall slowly but it won't interact properly with the world if the item is supposed to be smaller.
Adept the camera to your world, not your world to your camera.
More detailed answer I gave
I'm a beginner android game programmer, I use LIBgdx
I have a playState class
public PlayState(GameStateManager gsm) {
super(gsm);
obj = new Objects();
cam.setToOrtho(false, Game.WIDTH , Game.HEIGHT);
}
#Override
public void update(float dt) {
obj.update(dt);
}
I have an Objects class
public class Objects {
private Vector2 posObj;
private static final int MOVEMENT = 2;
private Vector2 velo;
private Texture objTx;
private Random rand;
private static final int FLUCTUATION = 400;
public Objects(){
objTX = new Texture("objies.png");
rand = new Random();
posObj = new Vector2(rand.nextInt(FLUCTUATION),rand.nextInt(FLUCTUATION));
velo = new Vector2(0, 0);
}
public void update(float dt){
}
Now, What I'm tring to do is:
Move this randomly generated object to the center of the screen and then dispose.
Serious Help required! Thank-you
Well, you know where your object is and you know where the middle is (Game.WIDTH/2 , Game.HEIGHT/2)
If the center is to the left of the object move it to the left, if center is above move object up etc.
So a very simple solution:
public void update(float delta){
if(posObj.x < Game.WIDTH/2){
velocity.x = MOVEMENT;
}
else {
velocity.x = -MOVEMENT;
}
if(posObj.y < Game.HEIGHT/2){
velocity.y = MOVEMENT;
}
else {
velocity.y = -MOVEMENT;
}
posObj.y += velocity.y * delta;
posObj.x += velocity.x * delta;
}
This might cause your object to jump around the middle without ever really hitting the exact coordinates. So you can check the distance from the object to the middle by adding this method to your object:
public Vector2d getPosition(){
return posObj;
}
And then check for the distance:
if( obj.dst(Game.WIDTH , Game.HEIGHT) <= closeEnough ){
obj = new Objects();
}
closeEnough is a distance you set.
I'm learning libgdx and currently doing a flappy bird demo. For fun I tried to implement when the score reached a certain number the bird sprite texture will update and change to another color. Instead of using the spritebatch and changing the color through tinting I wanted to create a new texture(png file).
The problem is since it is a sprite it needs to be animated so the wings will flap. When I try and update the texture at runtime it will only work but the animation wont play.
Here is my bird class:
public class Bird {
private static final int GRAVITY = -15;
private static final int MOVEMENT = 100;
private Vector3 position;
private Vector3 velocity;
private Rectangle bounds;
private Animation birdAnimation;
private Texture birdTexture;
private TextureRegion textureRegion;
private Sound flap;
public Bird(int x, int y){
position = new Vector3(x, y, 0);
velocity = new Vector3(0, 0, 0);
textureRegion = new TextureRegion(returnTexture());
birdAnimation = new Animation(textureRegion, 3, 0.5f);
bounds = new Rectangle(x, y, returnTexture().getWidth() / 3, returnTexture().getHeight());
flap = Gdx.audio.newSound(Gdx.files.internal("sfx_wing.ogg"));
}
public void update(float dt){
textureRegion = new TextureRegion(returnTexture());
birdAnimation = new Animation(textureRegion, 3, 0.5f);
birdAnimation.update(dt);
if(position.y > 0){
velocity.add(0, GRAVITY, 0);
}
velocity.scl(dt);
position.add(MOVEMENT * dt, velocity.y, 0);
if(position.y < 0){
position.y = 0;
}
velocity.scl(1/dt);
bounds.setPosition(position.x, position.y);
}
public TextureRegion getTexture() {
return birdAnimation.getFrame();
}
public Texture returnTexture(){
if(PlayState.score > 1){
return birdTexture = new Texture("birdanimation1.png");
}else{
return birdTexture = new Texture("birdanimation.png");
}
}
public Vector3 getPosition() {
return position;
}
public void jump(){
velocity.y = 250;
flap.play(0.15f);
}
public Rectangle getBounds(){
return bounds;
}
public void dispose(){
returnTexture().dispose();
flap.dispose();
}
}
Here is my animation class:
public class Animation {
private Array<TextureRegion> frames;
private float maxFrameTime;
private float currentFrameTime;
private int frameCount;
private int frame;
public Animation(TextureRegion region, int frameCount, float cycleTime){
frames = new Array<TextureRegion>();
int frameWidth = region.getRegionWidth() / frameCount;
for(int i = 0; i < frameCount; i++){
frames.add(new TextureRegion(region, i * frameWidth, 0, frameWidth, region.getRegionHeight()));
}
this.frameCount = frameCount;
maxFrameTime = cycleTime / frameCount;
frame = 0;
}
public void update(float dt){
currentFrameTime += dt;
if(currentFrameTime > maxFrameTime){
frame++;
currentFrameTime = 0;
}
if(frame >= frameCount){
frame = 0;
}
}
public TextureRegion getFrame(){
return frames.get(frame);
}
}
Here's my render code in my play state:
#Override
public void render(SpriteBatch sb) {
sb.setProjectionMatrix(cam.combined);
sb.begin();
sb.draw(bg, cam.position.x - (cam.viewportWidth /2), 0);
sb.draw(bird.getTexture(), bird.getPosition().x, bird.getPosition().y);
for(Tube tube : tubes){
sb.draw(tube.getTopTube(), tube.getPosTopTube().x, tube.getPosTopTube().y);
sb.draw(tube.getBottomTube(), tube.getPosBotTube().x, tube.getPosBotTube().y);
}
sb.draw(ground, groundPos1.x, groundPos1.y);
sb.draw(ground, groundPos2.x, groundPos2.y);
font.draw(sb, text, cam.position.x - gl.width / 2, cam.position.y + 200);
sb.end();
}
If you need any other classes just ask. I'm probably making a stupid mistake or just coding it entirely wrong for what I'm trying to achieve.
Thanks, Jackson
You need to NOT load your textures every single frame.
libgdx has its own Animation class so you don't need to make your own.
Here is an example on animation from libgdx's github:
2D Animation
To make it simple, just have 2 animaitons on Bird and switch between them when you need to.
Player Class
public class Player extends Sprite implements InputProcessor {
public Vector2 velocity = new Vector2();
private float speed = 500;
public Rectangle rectangle;
public Player(Sprite sprite){
super(sprite);
this.rectangle = sprite.getBoundingRectangle();
}
public void draw(SpriteBatch spriteBatch){
update(Gdx.graphics.getDeltaTime());
super.draw(spriteBatch);
}
public void update(float delta) {
rectangle = new Rectangle(getX() + velocity.x * delta,0,rectangle.getWidth(),rectangle.getWidth());
setX(getX() + velocity.x * delta);
}
}
PlayScreen Class
public class PlayScreen implements Screen {
private Player player;
private OrthographicCamera camera;
private OrthogonalTiledMapRenderer renderer;
private TiledMap map;
private Rectangle rightRectangle, leftRectangle, playerRectangle;
//private ShapeRenderer shapeRenderer;
#Override
public void render(float delta) {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
renderer.render();
renderer.getSpriteBatch().begin();
player.draw(renderer.getSpriteBatch());
renderer.getSpriteBatch().end();
//shapeRenderer.begin(ShapeType.Filled);
//shapeRenderer.setColor(0, 1, 0, 1);
//shapeRenderer.rect(
// player.getX() + player.velocity.x * delta, 0,
// player.rectangle.getWidth(), player.rectangle.getHeight());
//shapeRenderer.end();
}
#Override
public void resize(int width, int height) {
camera.viewportWidth = width;
camera.viewportHeight = height;
camera.update();
}
#Override
public void show() {
camera = new OrthographicCamera();
map = new TiledMap();
renderer = new OrthogonalTiledMapRenderer(map);
//shapeRenderer = new ShapeRenderer();
player = new Player(new Sprite(new Texture("img/player.png")));
rightRectangle = new Rectangle(1280,0,0,720);
leftRectangle = new Rectangle(0,0,0,720);
boolean wallLeft = leftRectangle.overlaps(player.rectangle);
boolean wallRight = rightRectangle.overlaps(player.rectangle);
if(wallLeft){
System.out.println("wallLeft Overlap");
player.velocity.x = 0;
}
else if(wallRight){
System.out.println("wallRight Overlap");
player.velocity.x = 0;
}
player.setPosition(
Gdx.graphics.getWidth()/2f - player.getWidth()/2f,
Gdx.graphics.getHeight()/2f - player.getHeight()/2f
- Gdx.graphics.getHeight()/5f);
}
}
Doesn't seem to be colliding correctly. The rightRectangle and leftRectangle are my screen side bounds. When I use the shapeRenderer, it produces the ShapeRendered rectangle and it will follow my player around. However, I believe that my player.rectangle is not moving at all for some reason, resulting in it not colliding with my side bounds. Any help would be greatly appreciated!
rightRectangle = new Rectangle(1280,0,0,720);
leftRectangle = new Rectangle(0,0,0,720);
A Rectangle is defined as Rectangle(x, y, width, height). It looks like you are trying to define it incorrectly as Rectangle(x1, y1, x2, y2). In the above, you have created two rectangles of 0 width.
