QUESTION
I am a bit new to pygame, and I don't know if there was a way to simplify this and it would also be nice if you could change colors while drawing. I already tried to implement this but I couldn't find a way to let it work. It's basically a simple pixel-art game:
...ANSWER
Answered 2022-Feb-28 at 12:44EDIT: Maybe this question should go on similar portal Code Review or Game Development
I keep drawing color in variable and use keys to change it.
1 = Red
, 2 = Green
, 3 = Blue
, 0 = Black
But now it needs to keep color
with pos
- and I use dictionary pressed[pos] = color
But maybe instead of pressed
you should create full list 2D for all squares in grid and put White
in all places at start. If you would colors as tuples i.e. (255,0,0)
instead string Red
then you could keep it in numpy.array
and simply save in text file or convert numpy.array
to Pillow.Image
and save as JPG/PNG/TIFF.
Because now it can draw in different colors so I don't check if pos not in pressed
when I press first button because it not allow to replace color in square.
There is not so much to simplify.
In DrawSquare()
you run MousePos()
many times but you could run it once and assign to variable.
You can use x, y = ...
instead of pos = ...
and pos[0]
, pos[1]
.
Or you can use both x, y = pos = ...
.
You can create cursor = Rect(...)
at start and later use cursor.topleft = new_position
to move it.
Maybe in draw.rect(...)
you could use directly tuples (x, y, width, height)
instead of Rect(x, y, width, height)
I used rules from PEP 8 -- Style Guide for Python Code
lower_case_names
for functions namesverbs
for functions names -convert
instead ofMousePos
(andnouns
for variables and classes)

QUESTION
I have this code that essentially translates pixels of an image to a block in minecraft and it gives you a "map" of where to put that block in order to form the image in the game: the code generates a csv file where each cell in the spreadsheet corresponds to a block.
I want to improve this and not only output the csv file, but also output a txt file with the minecraft commands that'll generate the image in game.
Also, those commands have to have a relative position to the player's (x, y, z) which should be informed in the code via a tuple or something.
So, assuming that the player is at 0, 0, 0 in game, and my csv looks like
Here's this same dataframe in dict form for testing
...ANSWER
Answered 2021-Dec-31 at 22:46I tried writing a solution to this based on un-pivoting the matrix of values into a coordinate representation, but the compression code ended up being hideously complicated, so I scrapped that, and wrote a solution based on a nested loop instead, which ended up being much easier to write.
Basically, this loops over rows, and within each row, it groups blocks of the same material, as long as those blocks are contiguous. (That's the purpose of itertools.groupby(), which is different from the Pandas groupby because the Pandas version will group non-contiguous values which are the same.)
QUESTION
I am trying to create a pixel-art making program using pygame (yes, I know there are better packages to use). The way that I am drawing pixels is via surface.set_at(). I need to know how to completely delete a pixel from a pygame surface, so that I can have an eraser tool. I do not want to fill the pixel in with the background color of the window, because that would still render when using pygame.image.save() to get an image file from the drawing. Can someone please help? Here is my code:
...ANSWER
Answered 2022-Jan-02 at 20:28As discussed in the comments, you can make a pixel transparent by setting it to a value whose alpha
value is zero.
QUESTION
I was trying to send a notification with an image after a bit of googling I found this code in stack overflow
even though the code below gives a notification with space for the image, the image doesn't load
What I have tried
I tried adding time.sleep() between few lines to give it some time to load the image
tried changing the interpreter to python 3.9
tried changing image source to another image
executing the code from another computer
none of these worked
...ANSWER
Answered 2021-Jul-05 at 13:12I tried using some local image from my computer as src
and it worked.
If it is not required for the image source to be online, simply download it and use it locally.
QUESTION
I've been trying to follow this tutorial on creating pixel art in Turtle: https://www.101computing.net/pixel-art-in-python/
And I tried to copy over their code, but when I put it into VS Code, I get the following error: AttributeError: 'Turtle' object has no attribute 'tracer'
Running their editor seems to work.
Any ideas on what the issue could be? All I did was copy and paste the code (and fix some issues with indents).
...ANSWER
Answered 2021-May-10 at 09:09From the docs
Changes since Python 2.6 The methods Turtle.tracer(), Turtle.window_width() and Turtle.window_height() have been eliminated. Methods with these names and functionality are now available only as methods of Screen.
The reason it works in their online IDE is that they have an older version of python.
You can use turtle.tracer(0)
.

Quick update I have added a little bit of code to adjust the character's movement, so when the character isn't idle the character faces the last position it was walking towards. But I have any issue with my character always facing left after any movement action. I also updated my character script:

QUESTION
I'm working on a pygame project but I'm having a few complications with the character's movement. The animation is not in sync (in lame terms), when I move right or left there is suppose to be an animation of the character moving left or right smoothly but in my case when the is moving either left or right I can still see the character image for when the character is in an idle position trailing the character when in walking motion. I also have an issue when my character jumps it doesn't come back own. I tweaked the character speed and refresh rate of the screen but nothing seems to help. Here is my code and image below.
File 1. Handles the running of the game

This because the first what you do in Knight.blitme
, is to draw the character in idle position. Then the left or right images is draw on top of it:

Install pixel-art
You can use pixel-art like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
