Response Time Challenge

[Matt 0]

This website clocks response time. I myself average around at about 250ms. But who cares about a human's response time?
I present a challenge to you to make an application that takes the test. You can use any language you want. Post the **average** response times below!

http://www.humanbenchmark.com/tests/reactiontime

**Rankings**

1. Slasheree with 33ms average in VB.net
2. GalacticGlum with 34ms average in C#
3. Marsh with 47ms average in C++
4. Matt with 60ms average in C#
5. Matt with 60ms average in Python

My submission with a C# application.

Ooh sounds fun, I will try to get time to give this a shot soon.

[Growlith1223 0]

i am so bad lol

[Marsh 0]

I think you might have missed the point of it Growlith your supposed to make a computer program to do it. Unless I misunderstood the point.

[Growlith1223 0]

ohhhhh, ok, well i guess that's not too hard to do then xD

@'Marsh':

Yeah, pretty much.

223ms. I really tried, the hand just can't move faster than 150ms and it takes almost 100ms for your brain to process it.

Did anyone read the post?

[GalacticGlum 0]

I did. I'm working on the program right now :)

Yeah, I just tried writing a lil 2 minute app and I got hung up on conditional expressions and operators.. I've forgotten so much.. Lol. Took me at least 5 minutes to write something as simple as

if (bool != true)
bool = !bool;

Absolutely ridiculous. =/

Very nice Slasheree! What language did you use?

[Slasheree 0]

VB.NET

[Marsh 0]

Source if anyone wants it

```
#include int main()
{
COLORREF green = 7002955;
COLORREF lastColor = 0;

while (true)
{
POINT p;
if (GetCursorPos(&p))
{
HDC dc = GetDC(NULL);
COLORREF color = GetPixel(dc, p.x, p.y);

if (color == green && lastColor != color)
{
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
}

lastColor = color;
ReleaseDC(NULL, dc);
}
}

return 0;
}
```

fHow is everyone getting such good times. Tell me your secrets.

[GalacticGlum 0]

Lol. I don't know. I just wrote a program! I thought mine would be behind everyone's.

[Mohenjo Daro 0]

I think the speed really has to do with the monitor
You could probably make it faster if the program looked at the code being sent or something (don't know tons about that sort of thing though)


[Matt 0]

A good part of it is your refresh rate on your monitor. Out of curiosity, what rates do you guys have? I'm at 60hz.

[Mohenjo Daro 0]

I'm at 60hz

[Slasheree 0]

Im at 60 Hz but I set a time delay onClick so it only clicked once per green screen

Python submission

>! 

```
from ctypes import windll
import pyautogui

dc = windll.user32.GetDC(0)

while (True):
   color = windll.gdi32.GetPixel(dc, 400, 200)

   if (color == 7002955):
       pyautogui.click()

```

I had also done that.
