Question

我正在尝试绘制图像，但我遇到了问题。这是代码：

@Override
public void render(float delta) {
    Gdx.gl.glClearColor(0,0,0,1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

    batch.begin();
    splash.draw(batch);
    batch.end();
}


@Override
public void show() {
    Texture splashTexture = new Texture("/img/intrologo.png");
    splash = new Sprite(splashTexture);
    splash.setSize(Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
}

我正试图在桌面上运行它。窗户跑了！但是我在控制台中遇到了很多错误。他们在这里：

我在LibGDX的论坛上问了这个问题，但几天后我没有得到任何回复。这就像是故意被忽略了。

文件'intrologo.png'肯定存在，它实际上出现在日食中！

我也无法关闭窗口。我必须强行退出窗口，这让我很紧张:(

谢谢！任何帮助表示赞赏！

Answer 1

此link显示了渲染图形的简单设置。

初始化Texture splashTexture时，通常使用libGDX将资源保存在名为“data”的资源文件夹中。尝试将其初始化为：

纹理splashTexture =新纹理（Gdx.files.internal（“data / intrologo.png”））;
您需要在批处理上调用draw方法，并将纹理与x和y坐标一起传递给它以将纹理绘制到。

batch.begin（）;

batch.draw（splashTexture，50,100）;

batch.end（）;

使用x和y坐标来品尝。

Answer 2

尝试更改此

Texture splashTexture = new Texture("/img/intrologo.png");

到此

Texture splashTexture = new Texture(Gdx.files.internal("img/intrologo.png"));

创建纹理时，需要文件而不是路径名。请参阅：http://libgdx.l33tlabs.org/docs/api/com/badlogic/gdx/graphics/Texture.html

在Assets文件夹中，它应该像

assets
|_img
 |_intrologo.png

LibGDX没有绘制图像？ [OS X]
