在检测播放器与许多相同对象（在本例中为墙砖）之间的碰撞时，我遇到了一个问题。问题是我的程序仅在与 最后添加的
墙砖接触时才检测到碰撞。这是用java写的…

我正在使用矩形（它们的相交方法）来检测碰撞。

代码示例：

更新图块：

        for (int i = 0; i < wallTileArr.size(); i++)
    {
        wallTile = wallTileArr.get(i);
        wallTile.update(p);
        if(wallTile.getBounds().intersects(Screen.getBounds()))
        {
            wallTile.draw = true;
        }
        else if(!wallTile.getBounds().intersects(Screen.getBounds()))
        {
            wallTile.draw = false;
        }
    }

这是我的课程，使墙从砖块中脱颖而出：

     public Wall(int x, int y, int length, int dir, WallTile wallTile)
     {
 this.x = x;
 this.y = y;
 this.length = length;
 this.wallTile = wallTile;


    for(int i = 0; i < length; i++)
    {
        if (dir == 0)
        {
            Methods.addWallTile(new WallTile(x+(wallTile.size*i), y));
        }
        else if (dir == 1)
        {
            Methods.addWallTile(new WallTile(x, y+(wallTile.size*i)));
        }

        else if (dir != 0 || dir != 1)
        {
            System.out.println("Error in setting direction: 0 = horizontal, 1 = vertical. Your input is: "+dir );
            //Methods.Exit(1);
        }

    }

}

这是我的班级，使房间或房屋带有墙壁：

     public HouseSmall_1(int x, int y,int size, int rotation, WallTile wallTile)
    {
this.x = x;
this.y = y;
this.wallTile = wallTile;
this.size = size;


if (rotation == 0)
{
    Methods.addWall(new Wall(x, y, size, 1, wallTile));
    Methods.addWall(new Wall(x+(size*wallTile.size), y, size, 1, wallTile));

    Methods.addWall(new Wall(x, y, size, 0, wallTile));
    Methods.addWall(new Wall(x, y+(size*wallTile.size), (size)/2, 0, wallTile));
    Methods.addWall(new Wall(x+wallTile.size+((size*wallTile.size)/2), y+(size*wallTile.size),(size/2), 0, wallTile));
}

}

将图块和墙壁添加到其arrayList中的代码：

public static void addWallTile(WallTile wallTile)
{
    Controller.wallTileArr.add(wallTile);
}

public static void addWall(Wall wall)
{
    Controller.wallArr.add(wall);
}

在wallTile.java文件中更新碰撞的代码：

    public void update(Player p)
{
    x+=Screen.movementX;
    y+=Screen.movementY;

    if(getBounds().intersects(p.upGetBounds()))
    {

        p.walk = false;

    }
    else
    {
        p.walk = true;
    }
}

为什么会这样呢？您如何建议我修复它？
