我想做一个扩展Actor类的对象。但每当我调用Stage的draw()方法时,它只会绘制我添加到它的按钮。这里是我的代码,也许有人可以帮助我?如何扩展Actor并在舞台上绘制它? Libgdx
代码为我的Screen类(假设我已经覆盖所有必要的方法和我进口的所有必要的类): 公共类播放屏幕实现屏幕{
SpriteBatch batch;
Game game;
Table table;
Skin skin;
Stage stage;
BitmapFont font;
TextButton button;
TextDisplay display;
public PlayScreen(MyGdxGame game, SpriteBatch batch){
this.game = game;
this.batch = batch;
//instantiating Stage, Table, BitmapFont, and Skin objects.
font = new BitmapFont(Gdx.files.internal("MyTruefont.fnt"));
table = new Table();
stage = new Stage();
skin = new Skin(Gdx.files.internal("Test.json"));
button = new TextButton("Start!", skin, "default");
display = new TextDisplay(font, this);
//Setting table properties
table.setWidth(stage.getWidth());
table.align(Align.center|Align.top);
table.setPosition(0, Gdx.graphics.getHeight());
table.padTop(30);
//Adding actors to table
table.add(button).padBottom(50);
table.add(display);
//Adding table to stage and setting stage as the input processor
stage.addActor(table);
Gdx.input.setInputProcessor(stage);
}
@Override
public void show() {
}
@Override
public void render(float delta) {
Gdx.gl.glClearColor(1, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
stage.draw();
batch.end();
}
这里是扩展演员我textDisplay形式类(再次假设所有其他方法已被重写,所有必要的类已导入):
public class TextDisplay extends Actor implements Drawable {
Texture texture;
BitmapFont font;
String str;
public TextDisplay(BitmapFont font, Screen screen){
this.font = font;
texture = new Texture(Gdx.files.internal("TextArea.png"));
str = "";
setLeftWidth(texture.getWidth());
setRightWidth(texture.getWidth());
setBottomHeight(texture.getHeight());
setTopHeight(texture.getHeight());
}
@Override
public void draw(Batch batch, float x, float y, float width, float height) {
batch.draw(texture, x, y);
}
哦,好的谢谢。我实现了drawable来查看它是否可以解决问题。我想我可以摆脱这一点。我仍然能够画出想要代表我的演员的形象吗?或者错过了什么? –
此外,标签类不会做我想要的。 –
你可以在'draw'方法中绘制任何你想要的东西。 – Tenfour04
