pygame.surface

[Graham]

The idea is that stars fall from top of screen to bottom.
I have this

1 2 3 4 5 6 7

starPosX = [50,100,200,300,400] starPosY = [-10,-20,-40,-500] imagelist = [filename for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']]   starx = random.choice(starPosX) stary = random.choice(starPosY) star = random.choice(imagelist)

in the loop I have

1	screen.blit(star, (starx, stary))

The error is

1 2 3 4

Traceback (most recent call last):   File "C:\Users\anybl\Python_Progs\shapes\Shapes.py", line 140, in <module>     screen.blit(star, (starx, stary)) TypeError: argument 1 must be pygame.Surface, not WindowsPath

My questions are
1)How can I use range 0,500 step 50 instead of starPosX = [50,100,200,300,400] I have tried various thing but nothing works.
2)How do I strip the path from the star.png so that variable star ends up just being = to red_star.png, or whichever colored star is chosen at random.

1.

1	startPosX = list(range(50, 450, 50))

2.

1 2 3 4 5

import os starpath = 'path/to/star.png' print(os.path.dirname(starpath)) # or print(os.path.split(starpath))

[Graham]

Thanks windspar,
The

1	startPosX = list(range(50, 450, 50))

worked.

But can't get the starpath to work.
This is fine a star falls from top of screen to bottom

1 2	starColor = pygame.image.load('purple_star.png') screen.blit(starColor, (starX, starY))

This works
prints a random star to screen

1 2	imagelist = [filename for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']] print (random.choice(imagelist))

What I want is to get the random star to fall

1 2	starColor = random.choice(imagelist) screen.blit(starColor, (starX, starY))

[Windspar]

Let see if this works. Since I believe you are using pathlib.
Need to load images

1	imagelist = [pygame.image.load(str(filename)) for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']]

or

1	star_images = [pygame.image.load(str(filename)) for filename in cd.iterdir() if filename.name.endswith('star.png')]

You also should convert images. Converting image to match pygame format will make it run faster.
Otherwise pygame will do it on the fly. It will convert it every loop.

1 2 3 4 5 6

star_images = [] for filename in cd.iterdir():     if filename.name.endswith('star.png'):         image = pygame.load(str(filename))         # if is alpha then use convert_alpha()         star_images.append(image.convert())

---

Before converting image. You need main pygame surface first.

[Graham]

Windspar, thanks for the help.
The error code I get now is

1 2 3 4

Traceback (most recent call last):   File "C:\Users\anybl\Python_Progs\shapes\Shapes.py", line 41, in <module>     image = pygame.load(str(filename)) AttributeError: module 'pygame' has no attribute 'load'

Below is the full code that I have, maybe it will help to figure where I'm going wrong.
It is nothing more than me trying various things with python as an introduction to my learning.

Yep I forgot image.

1	pygame.image.load

---

Only grab stars. If you have other images in folder.

1 2 3 4 5 6

star_images = [] for filename in cd.iterdir():     if filename.name.endswith('star.png'):         image = pygame.image.load(str(filename))         # if is alpha then use convert_alpha()         star_images.append(image.convert())

If you just want suffix.

1 2 3 4 5 6

star_images = [] for filename in cd.iterdir():     if filename.suffix == '.png':         image = pygame.image.load(str(filename))         # if is alpha then use convert_alpha()         star_images.append(image.convert())

1 2 3 4 5 6 7 8 9 10 11 12

# Define some colors BLACK = (0, 0, 0) WHITE = (255, 255, 255) BLUE = (0, 0, 255) GREEN = (0, 255, 0) RED = (255, 0, 0) PURPLE = (173,11,144) CYAN    =(0, 255, 255) YELLOW  =(255, 255, 0) ORANGE  =(255, 128, 0) GRAY    =(100, 100, 100) NAVYBLUE=(60, 60, 100)

Can be replace with pygame.Color(color_name)

Output:
>>> pygame.Color('navyblue')
(0, 0, 128, 255)

No need to define PI

1	PI = 3.141592653

just import pi

1	from math import pi

or

1	from math import pi as PI

Since this draw the same every time. Remove it from loop and apply it to another surface.

Still the same problem

Traceback (most recent call last):   File "C:\Users\anybl\Python_Progs\shapes\Shapes.py", line 143, in <module>     screen.blit(star_images, (starX, starY))# Place star on screen TypeError: argument 1 must be pygame.Surface, not list

Tried this in another window,

1 2 3 4 5 6

import random, pygame, sys from pathlib import Path cd = Path('.') pygame.init() imagelist = [filename for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']] print(random.choice(imagelist))

Which results in this.

C:\Users\anybl\Python_Progs\shapes>image.py pygame 1.9.4 Hello from the pygame community. https://www.pygame.org/contribute.html purple_star.png #Random color selected   C:\Users\anybl\Python_Progs\shapes>image.py pygame 1.9.4 Hello from the pygame community. https://www.pygame.org/contribute.html green_star.png # Random color selected

This works if you only want the one image.

1	StarColor = pygame.image.load('green_star.png')

Tried this, thinking th variable starChoice would be passed to the image.load function

1 2 3 4 5 6

imagelist = [filename for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']] starChoice = (random.choice(imagelist))           starX = (random.choice(starPosX)) starY = (random.choice(starPosY)) StarColor = pygame.image.load(starChoice)

Just get this

Traceback (most recent call last):   File "C:\Users\anybl\Python_Progs\shapes\Shapes.py", line 42, in <module>     StarColor = pygame.image.load(starChoice) pygame.error: Can't seek in this data source

The trick seems to be getting the result of the random selection passed in to,

1	screen.blit(starColor, (starX, starY))# Place star on screen

[Windspar]

add function before while loop and this after function.

1	background = create_background(size)

Line 62 replace screen.fill(WHITE).

1	screen.blit(background, (0,0))

---

1 2	imagelist = [filename for filename in cd.iterdir() if filename.suffix in ['.png', '.jpg', '.bmp']] starChoice = (random.choice(imagelist))

imagelist filename is a pathlib class. It is not a string.
try.

1	StarColor = pygame.image.load(str(starChoice))

I read somewhere that programming with Python was easy!
Glad I'm not here on my own or computer would be in canal!

Programming is a tool set. Can you go in your garage and make a couch. You probably could make a simple bookshelf. It takes time and practice. One simple rule. KISS (keep it simple stupid).

Here my example. This is how I would write it.
