Libgdx 混合两个面具？

Question

屏幕被分成两部分，我有两组纹理。

我想裁剪每个纹理组以适合屏幕的每个部分。如何使用混合（蒙版）实现这一点？

这是我用 MSPaint 制作的一张图片来描述情况：

Answer 1

我不知道如何用混合蒙版做，但你可以用剪刀测试做。

private Rectangle leftSide;
private Rectangle rightSide;

public void resize (int width, int height) {
    //...

    leftSide = new Rectangle(0, 0, width/2, height);
    rightSide = new Rectangle(width/2, 0, width/2, height);
}

public void render() {

    //...

    spriteBatch.begin();
    //draw background

    spriteBatch.flush();
    ScissorStack.pushScissors(leftSide);
    //draw left side stuff that is cropped
    spriteBatch.flush();
    ScissorStack.popScissors();
    ScissorStack.pushScissors(rightSide);
    //draw right side stuff that is cropped
    spriteBatch.flush();
    ScissorStack.popScissors();
    //draw any other stuff that is not cropped on top of everything else
    spriteBatch.end();
}
