屏幕分为两部分,我有两组纹理。
我希望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描述情况的图像:
答案 0 :(得分:2)
我不知道如何使用混合面具来做到这一点,但你可以通过剪刀测试来做到这一点。
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();
}
