java - ShapeRenderer 没有在图像后面绘制 FilledRectangles

问题描述

我正在尝试使用此代码在两个不同的图像后面绘制 FilledRectangles。但是 ShapeRenderer 没有绘制任何东西。

public void render(float delta) {

    shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
    shapeRenderer.setColor(tankColor);
    shapeRenderer.rect(tankButton.x, tankButton.y,
            tankButton.width+50, tankButton.height+50);
    shapeRenderer.setColor(notesColor);
    shapeRenderer.rect(notesButton.x, notesButton.y,
            notesButton.width+50, notesButton.height+50);
    shapeRenderer.end();

    batch.begin();

    batch.draw(assetsLoader.backTexture, 0, 0, screenWidth, screenHeight);

    assetsLoader.shadow.draw(batch, " Touch for Sound !",
            Gdx.graphics.getWidth() / 2f - 150 + 5,
            200 + assetsLoader.font.getCapHeight() + 5, 400, Align.center, false);
    assetsLoader.font.draw(batch, " Touch for Sound !",
            Gdx.graphics.getWidth() / 2f - 150,
            200 + assetsLoader.font.getCapHeight(), 400, Align.center, false);



    // draw tank and notes image
    batch.draw(assetsLoader.tankTexture, tankButton.x, tankButton.y,
            tankButton.getWidth(), tankButton.getHeight());
    batch.draw(assetsLoader.notesTexture, notesButton.x, notesButton.y,
            notesButton.getWidth(), notesButton.getHeight());


    batch.end();


}

解决方案

我想到了。我所要做的就是在插入填充矩形后开始另一批。这就是我所做的：

public void render(float delta) {

    batch.begin();

    batch.draw(assetsLoader.backTexture, 0, 0, screenWidth, screenHeight);



    assetsLoader.shadow.draw(batch, " Touch for Sound !",
            Gdx.graphics.getWidth() / 2f - 150 + 5,
            200 + assetsLoader.font.getCapHeight() + 5, 400, Align.center, false);
    assetsLoader.font.draw(batch, " Touch for Sound !",
            Gdx.graphics.getWidth() / 2f - 150,
            200 + assetsLoader.font.getCapHeight(), 400, Align.center, false);


    batch.end();

    shapeRenderer.begin(ShapeRenderer.ShapeType.Filled);
    shapeRenderer.setColor(tankColor);
    shapeRenderer.rect(tankButton.x-25, tankButton.y-25,
            tankButton.width+50, tankButton.height+50);


    shapeRenderer.setColor(notesColor);
    shapeRenderer.rect(notesButton.x-25, notesButton.y-25,
            notesButton.width+50, notesButton.height+50);
    shapeRenderer.end();



    batch.begin();

    batch.draw(assetsLoader.tankTexture, tankButton.x, tankButton.y,
            tankButton.getWidth(), tankButton.getHeight());
    batch.draw(assetsLoader.notesTexture, notesButton.x, notesButton.y,
            notesButton.getWidth(), notesButton.getHeight());

    batch.end();
