这是我的游戏屏幕的代码，我希望在触摸它时爆破我的气球。 方向是纵向。 但它似乎对我不起作用。

我正在使用 libgdx 的动画类将我的气球图像更改为它爆裂的图像。 我是 libgdx 的新手，无法弄清楚我在这里做错了什么。 作为 Actor ，我应该创建一个表格并布置我的气球元素吗？
最佳答案
尝试这样的事情:
private boolean ballonBursted(Rectangle ballon) {
Vector3 touchPos = new Vector3(Gdx.input.getX(), Gdx.input.getY(), 0);
camera.unproject(touchPos);
if (ballon.contains(touchPos.x, touchPos.y))
return true;
else
return false;
}
关于android - 这是在 LibGdx 中检测矩形触摸的正确方法吗？似乎对我不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25460029/
