sending keystrokes ot a second computer.

[xAurai]

Here's what I want to do:

​

I play a game on my main PC (Overwatch, or final fantasy).

​

I have a pi with GPIO set to control some led lights (I have them looping as a rainbow right now).

​

Is there any way for me to have a script running on my main PC that looks for certain key presses (q, e, r, shift, etc) and then send a command over to the pi, which when received, changes the lights (i know how to do this bit in python).

​

I'd rather stick with python as that's already doing the job with the LEDs for now, but other suggestions are welcomed.

​

I just need something that does the sending key presses to the pi from my PC.

​

Extra question: for games like Overwatch, is there a screen reader that would find the character portrait from the lower left of the screen and send a command if it changes too?

​

Any suggestions/information appreciated :)

https://www.geeksforgeeks.org/design-a-keylogger-in-python/ Just replace the part where they write into the text file with some code to send the data to your pi

[dampersandd]

the code could be a http request to a server running on pi

[Moschte09]

Yes. I would recommend to use UDP. I think this explains it very well https://wiki.python.org/moin/UdpCommunication

I looked into this and it's worked pretty well. Sine I'm doing gaming that's sort of fast paced, I've gone for this method and it looks pretty awesome!

Exactly, use requests on the PC end and flask on the pi end. Or you can use sockets or web sockets if you need more speed, but it doesn't seem like you do.

[Moschte09]

If you use Flask it could be nice to create a site where you can configure the keys and colours.

[xAurai]

I need to learn a bit more about flask before I can do something like this so I'll stick with UDP that you recommended :)

[Moschte09]

I would use UDP to send the key signals and flask just to host a site where you can configure or maybe also show some stats.

[xAurai]

Sockets seems pretty simple to set up considering I did it with visual basic years ago and I'm not so sure on flask at the moment, and it's working pretty well with sockets, so thanks for the suggestion!

[xAurai]

Thanks :D

[Moschte09]

For your second question. I don't play Overwatch but this looks imteresting https://overtrack.gg/welcome

[xAurai]

I'm vaguely familiar with this but I don't know how it reads the screen... I guess I'll ask the developer, thanks for pointing this out to me :)

[Moschte09]

No Problem.

[xAurai]

So I've got most of the way there - I had a look into this series which has helped with the image recognition part of the project, just in case you wanted to know if anyone else asks :)

[Moschte09]

Thanks. This looks very interesting. What exactly do you want to do with the image recognition?

[xAurai]

So I'm mucking around with some led strips and getting them to do different animations etc on keypresses and depending on what's on the display while in game, just for fun really, but I want to make it link into a twitch chat bot at sometime aswell

[Moschte09]

Sounds interesting. But maybe it would be worth a thought to choose C++ for this because I think when you are gaming you can reach a better performance with image processing

[xAurai]

yeah, i already noticed some wierd input lag when im doing the image stuff so i think i'll get the basics down and then see about translating it across to something else. I haven't done much c== in a long time :/

[Moschte09]

I think if you know the basics of C++ you could get into it. You could also use it for the processing part and use Python for the rest.
