I have created a button and I want to change its appearance on hover and on click. I get no errors, but it isn't working. It doesn't change the image when it is clicked or when it is hovered. The only image that is displayed is the one from playButtonStyle.up
.
Here is my code:
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Screen;
import com.badlogic.gdx.assets.AssetManager;
import com.badlogic.gdx.graphics.GL30;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureAtlas;
import com.badlogic.gdx.graphics.g2d.TextureRegion;
import com.badlogic.gdx.scenes.scene2d.InputEvent;
import com.badlogic.gdx.scenes.scene2d.InputListener;
import com.badlogic.gdx.scenes.scene2d.Stage;
import com.badlogic.gdx.scenes.scene2d.ui.*;
import com.badlogic.gdx.scenes.scene2d.utils.ClickListener;
import com.badlogic.gdx.scenes.scene2d.utils.Drawable;
import com.badlogic.gdx.scenes.scene2d.utils.TextureRegionDrawable;
import com.badlogic.gdx.utils.viewport.ScreenViewport;
import com.starships.MainClass;
import com.sun.prism.paint.Color;
import helpers.Info;
public class MainMenuScreen implements Screen {
MainClass game;
Stage stage;
private Texture background;
private AssetManager assets;
private TextureAtlas atlas;
private Skin skin;
private Table table;
private Button playButton;
public MainMenuScreen(MainClass mainClass) {
game = mainClass;
Gdx.input.setInputProcessor(stage);
stage = new Stage();
background = new Texture(Gdx.files.internal("Background.png"));
assets = new AssetManager();
assets.load("Buttons/PlayButtonAtlas.atlas", TextureAtlas.class);
assets.finishLoading();
atlas = assets.get("Buttons/PlayButtonAtlas.atlas");
skin = new Skin(atlas);
table = new Table(skin);
table.setBounds(0, 0, Info.WIDTH, Info.HEIGHT);
Button.ButtonStyle playButtonStyle = new Button.ButtonStyle();
playButtonStyle.up = skin.getDrawable("PlayButton");
playButtonStyle.over = skin.getDrawable("PlayButtonHover");
playButtonStyle.down = skin.getDrawable("PlayButtonPressed");
playButton = new Button(playButtonStyle);
table.add(playButton);
stage.addActor(table);
}
@Override
public void show() {
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(0, 0.7f, 0.8f, 1);
Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT);
stage.act(delta);
stage.draw();
}
@Override
public void resize(int width, int height) {
}
@Override
public void pause() {
}
@Override
public void resume() {
}
@Override
public void hide() {
}
@Override
public void dispose() {
stage.dispose();
}
}

Set InputProcessor
after initialisation of Stage
like this :
public MainMenuScreen(MainClass mainClass) {
game = mainClass;
stage = new Stage();
Gdx.input.setInputProcessor(stage); // This call should be after initialisation of stage.
background = new Texture(Gdx.files.internal("Background.png"));
...
...
}
