相机抖动矩阵相机

Question

我使用一个转换矩阵来移动屏幕，但是当玩家与一个物体碰撞时，玩家会抖动，好像它想同时在两个位置。看起来速度要继续下降，而块体却在向上推，我该如何修复它呢？

视频：这里

摄像机类：

class Camera
{
    public Vector2 Position;
    Viewport viewPort;
    public Vector2 cameraBounds;

    public float wasGround;

    public Matrix Transform()
    {
        var translationMatrix = Matrix.CreateTranslation(new Vector3(-Position.X, -Position.Y, 0));

        return translationMatrix;
    }

    public Player thing(Player player)
    {
        cameraBounds.X = player.Position.X - Game1.offset.X;
        if (cameraBounds.X > 0)
            Position.X = player.Position.X - Game1.offset.X;
        else
            Position.X = 0;

        //Problem      
        cameraBounds.Y = player.Position.Y - Game1.offset.Y;
        if (cameraBounds.Y > 0)
        {
            Position.Y = player.Position.Y - Game1.offset.Y;

            if (player.goingUp == false && (wasGround != player.ground))
                Position.Y = player.ground - Game1.offset.Y;

            wasGround = player.ground;
        }
        else
            Position.Y = 0;


        return player;
    }

    public Camera(Viewport viewport)
    {
        viewPort = viewport;
    }
}

我试图通过添加player goingUp和ground语句来解决这个问题，但这并没有帮助。

Answer 1

我解决了。这是关于操作顺序的。只需移动方法camera.thing()，如下所示：

            // TODO: Add your update logic here
        HandleInput(Keyboard.GetState());
        player.Update(gameTime);
        // delete from here
        Time += (float)gameTime.ElapsedGameTime.TotalSeconds;

        foreach (Block b in Blocks)
        {
            player = b.BlockCollision(player);
        }
        // place here
        camera.thing(player);

说明:在所有碰撞结束后，你必须设置摄像机的位置。

Answer 2

当你站在某个物体上的时候，我能看到的是速度的变化。因此，请尝试将摄像机位置转换为整数。或者，如果速度接近于0，则速度精确到0。

 cameraBounds.X = cInt(cameraBounds.X)
 cameraBounds.y = cInt(cameraBounds.y)
