在MonoGame中显示实时FPS

帧计数器

public class FrameCounter
{
    public FrameCounter()
    {
    }

    public long TotalFrames { get; private set; }
    public float TotalSeconds { get; private set; }
    public float AverageFramesPerSecond { get; private set; }
    public float CurrentFramesPerSecond { get; private set; }

    public const int MAXIMUM_SAMPLES = 100;

    private Queue<float> _sampleBuffer = new Queue<float>();

    public override bool Update(float deltaTime)
    {
        CurrentFramesPerSecond = 1.0f / deltaTime;

        _sampleBuffer.Enqueue(CurrentFramesPerSecond);

        if (_sampleBuffer.Count > MAXIMUM_SAMPLES)
        {
            _sampleBuffer.Dequeue();
            AverageFramesPerSecond = _sampleBuffer.Average(i => i);
        } 
        else
        {
            AverageFramesPerSecond = CurrentFramesPerSecond;
        }

        TotalFrames++;
        TotalSeconds += deltaTime;
        return true;
    }
}

public class FrameCounter

{

public FrameCounter()

{

}

public long TotalFrames { get; private set; }

public float TotalSeconds { get; private set; }

public float AverageFramesPerSecond { get; private set; }

public float CurrentFramesPerSecond { get; private set; }

public const int MAXIMUM_SAMPLES = 100;

private Queue<float> _sampleBuffer = new Queue<float>();

public override bool Update(float deltaTime)

{

CurrentFramesPerSecond = 1.0f / deltaTime;

_sampleBuffer.Enqueue(CurrentFramesPerSecond);

if (_sampleBuffer.Count > MAXIMUM_SAMPLES)

{

_sampleBuffer.Dequeue();

AverageFramesPerSecond = _sampleBuffer.Average(i => i);

}

else

{

AverageFramesPerSecond = CurrentFramesPerSecond;

}

TotalFrames++;

TotalSeconds += deltaTime;

return true;

}

使用方法：

private FrameCounter _frameCounter = new FrameCounter();

1	private FrameCounter _frameCounter = new FrameCounter();

protected override void Draw(GameTime gameTime)
    {
         var deltaTime = (float)gameTime.ElapsedGameTime.TotalSeconds;

         _frameCounter.Update(deltaTime);

         var fps = string.Format("FPS: {0}", _frameCounter.AverageFramesPerSecond);

         _spriteBatch.DrawString(_spriteFont, fps, new Vector2(1, 1), Color.Black);

        
    }
