单机游戏，为什么即使有功能，方块也不会移动

Question

我需要一些帮助，我有一个迷宫游戏，我需要推一个方块。如果我与块相交，第一个应该向右移动，第二个应该向左移动。问题是，当我相交时，我不能让它们中的任何一个移动。我们将不胜感激。

return block;
}
internal static Block CreatePushBlock(int x, int y, int w, int h)
{
return new Block(x, y, w, h, Color.Orange);
}
}

这段代码没有显示任何错误，但当我相交并按空格键时，不会发生任何事情。

Answer 1

Move()正在更改position变量，但块是从Rectangle字段绘制的，该字段不会更改以反映移动。

我建议采用以下相关性：public Rectangle Rectangle { get{return rectangle; } set {rectangle = value;} })

public void Move(float dx, float dy)
{
position.X += dx;
position.Y += dy;
Rectangle =  new Rectangle((int)position.X, (int)position.Y, Rectangle.Width, Rectangle.Height);
// you cannot set the X and Y of field structures directly.
}
