How to resize a sprite in Libgdx?
提问by Wazani
I have a problem with the method sprite.setSize(float x, float y)in Libgdx. It does not affect the size or the dimensions of the sprite. They remains fixed whatever I pass to the setSize() method.
我对sprite.setSize(float x, float y)Libgdx 中的方法有问题。它不会影响精灵的大小或尺寸。无论我传递给 setSize() 方法，它们都保持固定。
here is my code:
这是我的代码：
public class GameScreen implements Screen {
OrthographicCamera camera;
SpriteBatch batch;
Texture carTexture;
Sprite carSprite;
public GameScreen()
{
}
@Override
public void render(float delta) {
// TODO Auto-generated method stub
Gdx.gl.glClearColor(0,0,0,0);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
batch.begin();
carSprite.setSize(16, 32);
batch.draw(carSprite, 0 , 0);
batch.end();
camera.update();
}
@Override
public void resize(int width, int height) {
// TODO Auto-generated method stub
camera.viewportWidth=width;
camera.viewportHeight=height;
camera.update();
}
@Override
public void show() {
// TODO Auto-generated method stub
camera = new OrthographicCamera();
batch = new SpriteBatch();
carTexture = new Texture(Gdx.files.internal("NetRace.png"));
carTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear);
carSprite = new Sprite(carTexture);
}
@Override
public void hide() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
}
could you please find my mistake?
你能找出我的错误吗？

The problem was solved.
问题解决了。
I had to use sprite.draw(batch);instead of using Batch.draw(Sprite sp, float x, float y);since the Batch.draw(...)method takes the texture from the passed sprite and uses the texture in the drawing process which has a fixed width and a fixed height.
我不得不使用sprite.draw(batch);而不是使用，Batch.draw(Sprite sp, float x, float y);因为该Batch.draw(...)方法从传递的精灵中获取纹理，并在绘图过程中使用具有固定宽度和固定高度的纹理。
Another way to solve this problem is to use the batch.draw(Sprite, float x, float y, float width, float height);method in the SpriteBatchclass.
解决这个问题的另一种方法是使用类中的batch.draw(Sprite, float x, float y, float width, float height);方法SpriteBatch。
