LIBGDX 在一个屏幕上制作 5 个不同的按钮 [英] LIBGDX making 5 different buttons on one screen
问题描述
我有 5 个按钮需要做不同的事情，但它们没有，我需要知道如何让它们做不同的事情.
I have 5 buttons i need to make do different things but they don't and i need to know how to make them do it.
这是我的代码；
public class MainMenu implements Screen {
CrazyZombies game;
Stage stage;
TextureAtlas atlas;
Skin skin;
SpriteBatch batch;
Button play, option, quit, custom, store, menu;
public MainMenu(CrazyZombies game) {
this.game = game;
}
public void create () {
stage = new Stage();
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(0.09f, 0.28f, 0.2f, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
stage.act(delta);
stage.draw();
batch.begin();
batch.end();
}
@Override
public void resize(int width, int height) {
if (stage == null)
stage = new Stage(width, height, true);
stage.clear();
stage.setViewport(854, 480, true);
stage.getCamera().translate(-stage.getGutterWidth(), -stage.getGutterHeight(), 0);
Gdx.input.setInputProcessor(stage);
/**
* quit Button
*/
TextButtonStyle styleQuit = new TextButtonStyle();
styleQuit.up = skin.getDrawable("8layer");
styleQuit.down = skin.getDrawable("8layer");
quit = new Button(styleQuit);
quit.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y,
int pointer, int button) {
return true;
}
public void touchUp(InputEvent event, float x, float y,
int pointer, int button) {
}
});
/**
* End quit Button
*/
/**
* store Button
*/
TextButtonStyle styleStore = new TextButtonStyle();
styleStore.up = skin.getDrawable("9layer");
styleStore.down = skin.getDrawable("9layer");
store = new Button(styleStore);
store.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y,
int pointer, int button) {
return true;
}
public void touchUp(InputEvent event, float x, float y,
int pointer, int button) {
game.setScreen(new StoreScreen(game));
}
});
/**
* End store Button
*/
/**
* customs Button
*/
TextButtonStyle styleCustom = new TextButtonStyle();
styleCustom.up = skin.getDrawable("10layer");
styleCustom.down = skin.getDrawable("10layer");
custom = new Button(styleCustom);
custom.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y,
int pointer, int button) {
return true;
}
public void touchUp(InputEvent event, float x, float y,
int pointer, int button) {
game.setScreen(new CustomScreen(game));
}
});
/**
* End customs Button
*/
/**
* Options Button
*/
TextButtonStyle styleOptions = new TextButtonStyle();
styleOptions.up = skin.getDrawable("11layer");
styleOptions.down = skin.getDrawable("11layer");
option = new Button(styleOptions);
option.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y,
int pointer, int button) {
return true;
}
public void touchUp(InputEvent event, float x, float y,
int pointer, int button) {
game.setScreen(new OptionScreen(game));
}
});
/**
* End Options Button
*/
/**
* Play Button
*/
TextButtonStyle stylePlay = new TextButtonStyle();
stylePlay.up = skin.getDrawable("7layer");
stylePlay.down = skin.getDrawable("7layer");
play = new Button(stylePlay);
play.addListener(new InputListener() {
public boolean touchDown(InputEvent event, float x, float y,
int pointer, int button) {
return true;
}
public void touchUp(InputEvent event, float x, float y,
int pointer, int button) {
Gdx.app.log(CrazyZombies.LOG, "un-touched");
game.setScreen(new GameScreen(game));
}
});
/**
* End Play Button
*/
/**
* start Background
*/
TextButtonStyle styleMenu = new TextButtonStyle();
styleMenu.up = skin.getDrawable("background");
menu = new Button(styleMenu);
/**
* End Background
*/
stage.addActor(menu);
stage.addActor(play);
stage.addActor(option);
stage.addActor(store);
stage.addActor(custom);
stage.addActor(quit);
}
@Override
public void show() {
Audio.playMusic(true);
batch = new SpriteBatch();
atlas = new TextureAtlas("data/mainmenu/mainmenu.pack");
skin = new Skin();
skin.addRegions(atlas);
}
@Override
public void hide() {
dispose();
}
@Override
public void pause() {
}
@Override
public void resume() {
}
@Override
public void dispose() {
batch.dispose();
skin.dispose();
atlas.dispose();
stage.dispose();
Audio.dispose();
}
public void playButton(Button play) {
}
}
所以我的 5 个按钮已经设置好，还有动作和监听器，但现在它们什么都不做，当我单出一个按钮来测试它是否有效但可以从屏幕上的任何位置单击该按钮，所以我认为它是按钮区域的问题，但我不知道如何设置.
So my 5 buttons are set up and there actions and listeners but now they do not do anything and when i single one button out to test it works but the button can be clicked from any where on the screen so i think it is an issue with button areas but i do not know how to set it up.
我尝试过 .getheight()、.getWidth 等，但还是一样.尽管在我的纹理图集中，所有图像的高度和宽度都是相同的，因为它们都构成一张图像，这可能是我的问题吗?
I have tryed .getheight(), .getWidth etc. but it is still the same. Although in my texture atlas the height and width for all the images is the same as it all makes one image could this be my issue ?
推荐答案
实际上比这更简单.您需要设置按钮的边界.使用按钮的 .setBounds(x,y,width,height) 方法，它们还没有大小.设置边界后，点击区域应该是正确的.
Actually it's more simple than that. You need to set the bounds of your buttons. Use the .setBounds(x,y,width,height) method of the button, they do not have a size yet. The click area should be right after setting the bounds.
查看表格布局 libgdx 并使用表格.
