I didn’t know Roblox could interact with localhost, cool! But I’m curious about something, since the py script is posting something to localhost, wouldn’t this work with NodeJS?

Edit: YEP IT WORKS

HTTP 500 (INTERNAL SERVER ERROR)
Haven’t changed any of the code and I keep getting this error, where did I go wrong.

#27

You may not be hosting the server correctly, that’s probably my only guess. google the error if you need to

#28

Already fixed it, only issue was I forgot the template folder and index.html

I optimized the code to allow me to reuse the last pixels. I started getting about 3-5 fps on 200X100. Using lazy loading and lazy clearing for when I join and leave to prevent crashing.

Trying to learn python so I can compress the data when sending it over and uncompressed it on roblox’s side.

Any idea?

#34

I got the same! But if I go on the website manually it displays the correct thing.

#35

Try creating a folder named “templates” in the place where your python script is located and put a file called “index.html” in there

#36

Im pretty sure roblox doesnt allow this. Might be wrong.

#38

is there way to customize it like if a key pressed ???

#39

didnt work output HTTP 500 (INTERNAL SERVER ERROR)
even tho i added the folder and file what address running on all addresses (0.0.0.0)

PermissionError: [Errno 13] Permission denied: ‘ss.png’

#42

I am getting HTTP 500 (INTERNAL SERVER ERROR)
Is there a way to fix this?

#45

Cool, this looks great! I’ve made stuff like this before that played videos and high res images, but ones that worked in-game using some webserver stuff.

Making a frame for each pixel has some issues performance, though, because of how laggy it is. I think you’d need something like CanvasDraw to render it performantly.

#46

Write ‘sudo’ before the command where you run the program and then enter your password. It will run the code as root and you should not get Access Denied errors.

i dont really understand by sudo with what

#48

My bad, I meant in the terminal run “sudo python3 RblxDesktop.py” or if that doesn’t work try “sudo python RblxDesktop.py” in the terminal. You can do this by right clicking on the folder that the python file is in and clicking Open in command line, or open in terminal, something along those lines and then run the comman from there.

sudo is for macos and Linux

But if you are on windows try:

Right click → Run as administrator

I don’t think you can do 320p because there is a hard limit where the gui would stop rendering(Am I the first to discover this limit of 80k something frames)

No, I tried with frames too at first but it was too good to be true. I have also done the same project and achieved around 40 fps on 256x144 display. You could also take a look at this project. From what I see they have achieved HD resolution but very low fps of course. Screen sharing in Roblox

Edit: I use the CanvasDraw module by @Ethanthegrand14: CanvasDraw - A powerful pixel-based graphics engine (Draw pixels, lines, triangles, read PNG image data, and much more!)

#51

I do have a idea though to actually have a refreshing screen
the parts get premade
then the screen can loop through folders and change the color of the part
to something else

#52

This is not working for me, Roblox & Python are giving me a bunch of errors.
