[英]Superposed the sprites with libGDX
我想叠加两个精灵,但是,当我调整窗口大小时,精灵会移动...
我的代码:
public void resize(int width, int height) {
// TODO Auto-generated method stub
if ( height < width ){
spriteAbalone.setScale(height/700f);
billeBlanche.setScale(height/700f);
}
else{
spriteAbalone.setScale(width/700f);
billeBlanche.setScale(width/700f);
}
spriteAbalone.setPosition((width-700)/2, (height - 700)/2);
billeBlanche.setPosition((width-400)/2,(height-400)/2);
camera.setToOrtho(false, width, height);
camera.update();
}
@Override
public void show() {
// TODO Auto-generated method stub
float screenW = Gdx.graphics.getWidth();
float screenH = Gdx.graphics.getHeight();
camera = new OrthographicCamera();
camera.setToOrtho(false, screenW, screenH);
batch = new SpriteBatch();
spriteAbalone = new Sprite(new TextureRegion(new Texture(Gdx.files.internal("data/AbaloneCS5.gif")), 0, 0, 704, 704));
spriteAbalone.setSize(700 , 700);
spriteAbalone.setOrigin(704/2,704/2);
billeBlanche = new Sprite(new TextureRegion(new Texture(Gdx.files.internal("data/billeblanche.gif")),0,0,200,200));
billeBlanche.setSize(65, 65);
billeBlanche.setOrigin(704/2,704/2);
}
Sprite#setOrigin设置相对于精灵位置的原点,以进行缩放和旋转。 在此代码中,您为两个精灵设置了相同的原点,尽管其中一个非常小:
spriteAbalone = new Sprite(new TextureRegion(new Texture(Gdx.files.internal("data/AbaloneCS5.gif")), 0, 0, 704, 704));
spriteAbalone.setSize(700 , 700);
spriteAbalone.setOrigin(704/2,704/2);
billeBlanche = new Sprite(new TextureRegion(new Texture(Gdx.files.internal("data/billeblanche.gif")),0,0,200,200));
billeBlanche.setSize(65, 65);
billeBlanche.setOrigin(704/2,704/2);
将billeBlanche来源更改为此:
billeBlanche.setOrigin(200/2,200/2);
同样,在调整大小时 ,您为子画面设置的位置始终是固定的(width-700)/ 2或(width-400)/ 2-,但是您的子画面大小不同。 这就是他们“行动”的原因。
