相機抖動矩陣相機

Question

我使用的是平移矩陣來移動屏幕，但是當播放器與某個對象碰撞時，播放器會抖動，好像它想同時位於2個位置一樣。 似乎在塊將其推上時速度要繼續下降，我該如何解決呢？

相機類別：

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;
    }
}

我試圖通過添加玩家goingUp和ground if語句來解決該問題，但這沒有幫助。

Answer 1

我解決了 它與操作順序有關。 只需移動方法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);

說明：完成所有碰撞后，您必須設置攝像機位置。

當您靜止不動時我看到的是速度變化。 因此請嘗試將相機位置轉換為整數。 或如果速度接近0，則使速度精確為0。

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