【问题描述】:
我是 LibGdx 新手,并试图让我的冰淇淋图像可触摸。 我想知道如何设置输入过程(通过触摸屏幕)。 我需要再上一堂课吗?当我尝试实现输入过程时 我的 Prac1 类,JAVA 不允许我在不更改类抽象的情况下实现。具体来说,我喜欢在用户触摸图像时制作它 ,它计算触摸的次数。这是我的代码,感谢您的帮助。
import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
public class Prac1 extends ApplicationAdapter {
int w,h,tw,th =0;
OrthographicCamera camera;
SpriteBatch batch;
Texture img;
@Override
public void create () {
w = Gdx.graphics.getWidth();
h = Gdx.graphics.getHeight();
camera = new OrthographicCamera(w, h);
camera.position.set(w/2, h/2, 0);
camera.update();
batch = new SpriteBatch();
img = new Texture(Gdx.files.internal("iceCream.png"));
tw = img.getWidth();
th = img.getHeight();
}
@Override
public void render () {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
batch.draw(img, camera.position.x - (tw/2), camera.position.y - (th/2));
batch.end();
}
}
