这里我有一个代码，图片在地图上移动。
如何在与地图图块交互时使这张照片更清晰？我是java的初学者，所以我没有想法。非常欢迎任何帮助或建议。

谢谢你的帮助！

好的方法是分离视觉和现实模型。它意味着在程序的深处，你有“物理规则”和所有对象，并且基于该模型，你可以绘制它。
您可以从创建类
开始public class ObjectInMyGame{
private int posx;
private int posy;
private int width;
private int height;
private Image image;
private int movingX;
private int movingY;
//Note that it is good to use Point or something like that, instead of posx, posy.
}
然后有一种“游戏控制器”是好的，它正在运行你的整个世界。
public class GameController{
List<ObjectInMyGame> objects;
public updateGame(){
for (ObjectInMyGame object : objects){
object.doSomething(); //sometimes it is good idea to let objects itself do something
}
}
}
例如，当您移动对象时，您可以检查是否发生碰撞然后决定要做什么。
