我想做一個擴展Actor類的對象。但每當我調用Stage的draw()方法時,它只會繪製我添加到它的按鈕。這裏是我的代碼,也許有人可以幫助我?如何擴展Actor並在舞臺上繪製它? Libgdx
代碼爲我的Screen類(假設我已經覆蓋所有必要的方法和我進口的所有必要的類): 公共類播放屏幕實現屏幕{
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();
}
這裏是擴展演員我textDisplay形式類(再次假設所有其他方法已被重寫,所有必要的類已導入):
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,好的謝謝。我實現了drawable來查看它是否可以解決問題。我想我可以擺脫這一點。我仍然能夠畫出想要代表我的演員的形象嗎?或者錯過了什麼? –
此外,標籤類不會做我想要的。 –
你可以在'draw'方法中繪製任何你想要的東西。 – Tenfour04
