Java 总是发生碰撞

我创建了一个tilemap和一个播放器（现在只是一个曲线）。我将瓷砖贴图和播放器放在屏幕上，但播放器位于左上角，并且总是卡在瓷砖中。我不知道如何：

把它从角落里拿出来

阻止碰撞的发生，因为它是非阻塞块

在编写代码之前，您需要了解以下几点：

tilesheet是一张有不同瓷砖的纸，它会

[未阻止，未阻止]
[封锁，封锁]

这是我的对象超类的碰撞部分（我知道它看起来很像，但在开始之后，你可以得到漂移）：

如果您还需要什么，请告诉我，我会给您。

在

calculateCorners

中发生的事情（以及该方法操作的变量）也可能与此相关。@MickMemonic好的，添加了它。您可能需要调用重新绘制或在某处验证，手动调整窗口大小以强制重新绘制，并查看播放器是否移动。
