I have created an image's rectangle of a sprite using the command, pygame.image.get_rect(). When locating coordinates of key points on the rectangle such as bottomleft by drawing dots, I see that the rectangle's dimensions are completely different to the image's dimensions. In this case, the image is just the arrow head. The top right coordinate of the rectangle is correct, however the bottom left coordinate isn't.
Test to see rectangle
code to draw dots:
pygame.draw.circle(simulation_screen, red, velocity_arrow.rect.topright, 2)
pygame.draw.circle(simulation_screen,red,velocity_arrow.rect.bottomleft,2)
How can I resize the rectangle so that it fits the image?
pygame.Surface.get_rect.get_rect() returns a rectangle with the size of the Surface object. This function does not consider the drawing area in the image. You can find the bounding rectangle of the painted area in the surface, with pygame.Surface.get_bounding_rect:
bounding_rect = image.get_bounding_rect()
bounding_rect.move_ip(target_rect.topleft)
See the example. The black rectangle is the Surface rectangle and the red rectangle is the union of the mask component rectangles:
repl.it/#Rabbid76/ImageHitbox
import pygame
pygame.init()
window = pygame.display.set_mode((400, 400))
clock = pygame.time.Clock()
try:
my_image = pygame.image.load('icon/Bomb-256.png')
except:
my_image = pygame.Surface((200, 200), pygame.SRCALPHA)
pygame.draw.circle(my_image, (0, 128, 0), (60, 60), 40)
pygame.draw.circle(my_image, (0, 0, 128), (100, 150), 40)
run = True
while run:
clock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
pos = window.get_rect().center
my_image_rect = my_image.get_rect(center = pos)
bounding_rect = my_image.get_bounding_rect()
bounding_rect.move_ip(my_image_rect.topleft)
window.fill((255, 255, 255))
window.blit(my_image, my_image_rect)
pygame.draw.rect(window, (0, 0, 0), my_image_rect, 3)
pygame.draw.rect(window, (255, 0, 0), bounding_rect, 3)
pygame.display.flip()
pygame.quit()
exit()
I have the same problem, and I think because of this line:
image = pygame.transform.scale(image, (x, y))
After scaling the image in gimp, everything is working as intended.

I'm trying to make a game using pygame but I came up with an issue of people getting annoyed of the resolution they're working with, and can't resize window without stretching it.
Here is an example picture of what I'm trying to achieve.
here's what I tried.
window.blit(pg.transform.scale(screen, (window.get_size())), (0, 0)) # The game screen stretching
PS: It's hard to explain so I had to show an image
Use the following algortihm:
Get the bounding rectangle of the image and set the center of the rectangle to the center of the destination rectangle.
Use pygame.Rect.fit() to resize and move the aspect ratio rectangle into the destination rectangle.
Use the size of the new rectangle to scale the image.
blit the image at the position of the rectangle.
def blit_fit(dest_surf, image, dest_rect):
image_rect = image.get_rect(center = dest_rect.center)
fit_rect = image_rect.fit(dest_rect)
scaled_image = pygame.transform.scale(image, fit_rect.size)
dest_surf.blit(scaled_image, fit_rect)
Minimal example:
import pygame
pygame.init()
window = pygame.display.set_mode((300, 300))
clock = pygame.time.Clock()
font = pygame.font.SysFont(None, 100)
image = font.render("Screen", True, (255, 255, 0))
pygame.draw.rect(image, (255, 255, 255), image.get_rect(), 1)
def blit_fit(dest_surf, image, dest_rect):
image_rect = image.get_rect(center = dest_rect.center)
fit_rect = image_rect.fit(dest_rect)
scaled_image = pygame.transform.scale(image, fit_rect.size)
dest_surf.blit(scaled_image, fit_rect)
run = True
while run:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
window.fill(0)
blit_fit(window, image, window.get_rect())
pygame.display.flip()

i wanted to draw a circle in pygame that is empty, i mean you should see behind surface through it.
i wrote a code that find all the colored pixels in a surface and empty their coordinates in the other surface.
def draw_empty(surf1, surf2, pos):
"""makes surf2 pixels empty on surf1"""
pixobj2 = pygame.PixelArray(surf2)
empty = []
for x in range(len(pixobj2)):
for y in range(len(pixobj2[x])):
if pixobj2[x][y]!=0:
empty.append((x,y))
del pixobj2
pixobj1 = pygame.PixelArray(surf1)
for pix in empty:
pixobj1[pix[0]+pos[0]][pix[1]+pos[1]] = 0
del pixobj1
window = pygame.display.set_mode((600, 600))
white_surf = pygame.surface.Surface((600, 600))
white_surf.fill((255, 255, 255))
circle_surf = pygame.surface.Surface((50, 50))
pygame.draw.circle(circle_surf, (1, 1, 1), circle_surf.get_rect().center, 25)
pic = pygame.image.load('pic.png')
pic = pygame.transform.scale(pic, (600, 600))
done = False
while not done:
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
sys.exit()
draw_empty(white_surf, circle_surf, (200, 200))
window.blit(pic, (0, 0))
window.blit(white_surf, (0, 0))
pygame.display.update()
pygame.time.Clock().tick(60)
i expected to see background picture through that circle but the circle i just black, is this even possible to do that? can somebody help me with this?
P.S.
by empty, i mean like a hole in my front surface
Just use the draw() function:
pygame.draw.circle(Surface, color, pos, radius, width=0)
width represents the size of the circumference curve. When it is 0, the circle is solid. If you set it to 1, the edge will be only one pixel wide (an empty circle).
edit: to draw a circle with a sprite, you can use this code†:
import pygame
import pygame.gfxdraw
IMG = pygame.Surface((30, 30), pygame.SRCALPHA)
pygame.gfxdraw.aacircle(IMG, 15, 15, 14, (0, 255, 0))
pygame.gfxdraw.filled_circle(IMG, 15, 15, 14, (0, 255, 0))
class img(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.image = IMG
self.rect = self.image.get_rect(center=(150, 200))

You can draw the shape the same way you would if it had a color or surface image, and then just set the fill to a transparent color using:
empty = (255,255,255,0)
surface.fill(empty)
You will have to figure out how to add this to your code without breaking it, or rewrite it but, first you will need to make a set with three numbers
white = (255, 255, 255)
next use the function
pygame.draw.rect(canvas_name, set_name, (100, 100, 100, 100))
last use
pygame.display.flip()
#Initializes pygame import pygame, random, sys, time, math pygame.init()
#Creates screen screen = pygame.display.set_mode((400, 350)) pygame.display.set_caption("Game")
#Initializes screen running = True while running: pass
#Colors screen white = (255, 255, 255) screen.fill(white)
#Draws rectangle num1 = random.randrange(0, 255) num2 = random.randrange(0, 255) num3 = random.randrange(0, 255)
color = (num1, num2, num3) pygame.draw.rect(screen, color, pygame.Rect(100, 100, 60, 60), )
pygame.display.flip()
