TextureRegion 以错误的方式切割纹理

Question

我想要一个包含 3 个矩形的背景纹理，我想用它们创建动画，- texture

但是第一个矩形切割方式正确，另外两个切割方式笨拙 Proper way, Dumb way #1, Dumb way #2

这是我的代码。

    public class MainMenu implements Screen{

    Texture background_main;
    TextureRegion[] background_textures;
    Animation background_animation;
    SpriteBatch batch;
    TextureRegion current_frame; 
    float stateTime;
    BobDestroyer game;
    OrthographicCamera camera;

    public MainMenu(BobDestroyer game){
       this.game = game;
}

    @Override
    public void show() {
        camera = new OrthographicCamera();
        camera.setToOrtho(true, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
        batch = new SpriteBatch();
        background_main = new Texture(Gdx.files.internal("main_menu_screen/Background.png"));
        background_textures = new TextureRegion[3];

        for(int i = 0; i<3; i++){
            background_textures[i] = new TextureRegion(background_main,0, 0+72*i, 128, 72+72*i);
        }
        background_animation = new Animation(2f,background_textures);
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT | GL20.GL_DEPTH_BUFFER_BIT);
        stateTime += Gdx.graphics.getDeltaTime(); 
        current_frame = background_animation.getKeyFrame(stateTime, true);
        batch.begin(); 
        batch.draw(current_frame,0, 0,Gdx.graphics.getWidth(),Gdx.graphics.getHeight());    
        batch.end();
    }
}

如果我没理解错的话，你是想创建 3 个相同 width/height 的 TextureRegions 吗？如果是，您的问题可能与：

new TextureRegion(background_main,0, 0+72*i, 128, 72+72*i)

我想你会想要：

new TextureRegion(background_main,0, 0+72*i, 128, 72)

因为 128x72 是您下一个 TextureRegions 的 width/height（不是 x/y 位置），您不希望它们都具有相同的高度 (72) 而不是不同的高度 (72+ 72*i)?
