C# XNA/MonoGame-如何使用矩形作为边界框检查列表中每个对象的碰撞

我正在使用MonoGame框架制作一个平台游戏。该游戏有一些基本的机制，如：重力和碰撞检测，只对列表中的最后一个对象有效

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

以下是游戏区域的代码（主脚本）： `

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

`

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

玩家脚本：

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

`

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

该框仅继承自

Object2D.cs

，未更改任何代码

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

但是在

MainGame.cs

的更新无效中，我们正在检查碰撞：

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

`

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

if（GamePad.GetState（PlayerIndex.One）.Buttons.Back==ButtonState.Pressed | | Keyboard.GetState（）.IsKeyDown（Keys.Escape））
退出（）；
对于（int i=0；ik.Update（））`

代码是有效的，但只适用于列表中的第二个对象，当我移动到添加的第一个框上时，由于重力的作用，我会摔倒

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

我不知道为什么它只检查框列表中的最后一个框。

一旦发现冲突，就不会停止搜索。更改此代码：

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

    for (int i = 0; i < boxes.Count; i++)
    {
        if (player.Colliding(boxes[i]))
        {
            player.falling = false;
        }

        if (!player.Colliding(boxes[i]))
        {
            player.falling = true;
        }
    }

for（int i=0；i

…类似于：

        if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
            Exit();

        for (int i = 0; i < boxes.Count; i++)
        {
            if (player.Colliding(boxes[i]))
            {
                player.falling = false;
            }

            if (!player.Colliding(boxes[i]))
            {
                player.falling = true;
            }
        }

        player.Update();
        boxes.ForEach(k => k.Update());`

var isFalling=true;  // assume the worst

for (int i = 0; i < boxes.Count; i++)
    {
        if (player.Colliding(boxes[i]))
        {
            isFalling = false;
            break;
        }
    }

player.falling = isFalling;

var isFalling=true；//做最坏的打算
对于（int i=0；i

谢谢！我会试试这个。是的，它只是没有检测到添加的第一个框的冲突，我只是做了一个测试，如果删除了第二个框，它会检测到第一个框的冲突，但是当添加第二个框时，它只检测到第一个框的冲突抱歉，它只检测到第二个框的冲突，当添加第二个框时
