手势 FreeDrag 性能

我有一个简单的问题，我正在尝试为 Windows Phone 制作一款大型游戏，但我仍然有一个重要的瓶颈/问题/性能不佳。

我使用过 mango profiler，但我没有发现任何问题，事实上它只使用了我手机上 10% 的 cpu。

让我告诉你问题所在。

这是我的更新

protected override void Update(GameTime gameTime)
    {
        if (TouchPanel.IsGestureAvailable)
        {
            var gs = TouchPanel.ReadGesture();
            switch (gs.GestureType)
            {
                case GestureType.FreeDrag:
                    Position += gs.Delta;
                    break;
            }
        }
        base.Update(gameTime);
    }

这是我的绘制，其中地图是 20x15 纹理 2D

protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();          
        spriteBatch.Draw(map, Position, null, Color.Red, 0f, Vector2.Zero, 1f, SpriteEffects.None, 1f);
        spriteBatch.End();

        base.Draw(gameTime);
    }

问题是，绘制对于更新来说似乎太慢了，或者有点慢。

例如：

1）我非常缓慢地拖动右侧的屏幕 ->地图纹理正确地在右侧移动

2) 我将屏幕拖动到右侧，然后拖动到左侧，速度相当快 ->地图纹理正确地在右侧移动，但在向左侧移动时有一点滞后，就像它仍在右侧移动一样。

3）我以圆形方式拖动屏幕，在 1 秒内画一个圆 ->好吧，地图需要 3 秒才能循环移动..

我做错了什么？

我应该给你看一个 youtube 视频吗？

非常感谢你！！卢卡

I have a simple question, I'm trying to make an huge game for Windows Phone, but I still have a important bottleneck/issue/bad performance.

I've used the mango profiler, but I have seen no problem, infact it's using only 10% cpu on my phone.

Let me show you the problem.

This is my Update

protected override void Update(GameTime gameTime)
    {
        if (TouchPanel.IsGestureAvailable)
        {
            var gs = TouchPanel.ReadGesture();
            switch (gs.GestureType)
            {
                case GestureType.FreeDrag:
                    Position += gs.Delta;
                    break;
            }
        }
        base.Update(gameTime);
    }

This is my Draw, where map is a 20x15 Texture2D

protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        spriteBatch.Begin();          
        spriteBatch.Draw(map, Position, null, Color.Red, 0f, Vector2.Zero, 1f, SpriteEffects.None, 1f);
        spriteBatch.End();

        base.Draw(gameTime);
    }

The problem is that seems that the DRAW is TOO slow for the UPDATE, or kinda of.

For Example:

1) I drag the screen on the right, very slowly -> the map texture is correctly moving on the right

2) I drag the screen on the right, then on the left, quite fast -> the map texture is correctly moving on the right, but has a little lag when moving on the left, like it's still moving on the right..

3) I drag the screen circularly making a circle in 1 second -> well, the map needs 3 seconds to make a move circularly..

What I'm doing wrong??

Should I show you a youtube video??

Thanks you very much!!
