            }
        }
    }
}

}

是我的代码，但它只适用于数组中等于 [0] 的矩形，这是为什么呢？

我知道数组中有对象，因为我可以从其他对象中获取所有信息

            for(int i = 0; i < rect.length; i++) {
            if (playerRect.getBounds().intersects(rect[i].getBounds())) {
                System.out.println("You are inside the object: "+i);
                setXY(getX(), getY());//Stop moving    
            } else {
                setXY(getX() + dx, getY() + dy);//move
            }
        }

是我想要发生的事情，但基本上它会说我在所有对象中，但它只会在我与 rect[0] 相交时阻止我移动，而不是阻止我在所有索引中移动数组。

您正在使用object.objectMap.get(i).rect.y而不是object.objectMap.get(i).rect.x在 x 参数位置。

 rect[i] = new Rectangle(object.objectMap.get(i).rect.y, object.objectMap.get(i).rect.y, object.objectMap.get(i).rect.width, object.objectMap.get(i).rect.height);

更正的代码

rect[i] = new Rectangle(object.objectMap.get(i).rect.x, object.objectMap.get(i).rect.y, object.objectMap.get(i).rect.width, object.objectMap.get(i).rect.height);
