How to rotate mask of image pygame

Closed 10 months ago.
Hi im tryin to make simulator for parking with use of genetic alghorythm, and from the begining im having trouble with colliding with mask i dont what im doing wrong but my track mask and car mask are colliding very wierdly.
Below is how im drawing and rotating my car
def draw(self, screen): # 3
self.car_rect.topleft = (int(self.x), int(self.y))
rotated_image = pygame.transform.rotate(self.car_img, self.angle)
new_rect = rotated_image.get_rect(center=self.car_img.get_rect(topleft=self.car_rect.topleft).center)
self.car_mask = pygame.mask.from_surface(rotated_image)
screen.blit(rotated_image, new_rect.topleft)
Theres how im using collision
def collide(self ,mask):
self.car_mask = pygame.mask.from_surface(self.car_img)
offset = (int(self.x),int(self.y))
poi = mask.overlap(self.car_mask,offset)
return poi
Below is my game loop where im moving with car and drawing it
screen.screen.fill((175, 174, 174)) # 9
screen.screen.blit(track.track_img, (0, 0))
car1.draw(screen.screen)
pygame.display.flip()
pygame.display.update()
clock.tick(60)
events = pygame.event.get()
pressed = pygame.key.get_pressed()
car1.speed *= 0.9
if pressed[pygame.K_UP]: car1.speed += 0.5 # 6
if pressed[pygame.K_DOWN]: car1.speed -= 0.5 # 6
if pressed[pygame.K_LEFT]: car1.angle += car1.speed / 4 # 7
if pressed[pygame.K_RIGHT]: car1.angle -= car1.speed / 4 # 7
car1.x += car1.speed * math.cos(math.radians(+car1.angle)) # 8
car1.y -= car1.speed * math.sin(math.radians(car1.angle)) # 8
offset = (int(car1.x), int(car1.y))
if car1.collide(track.track_mask) != None:
print("collide")
i dont know where problem is because mask i moving with car but on corners it stuck even if its now on the border. For offset im using just position of car bcs map is drawing at 0,0.

Pygame Drawing a Rectangle

I try to print a square for use as a hitbox because the collision detection doesn't work on images. But when I try to draw a test square in setup it doesn't appear. I have tried moving the command, and changing it but nothing worked. And that is only for the square. The images appear and move perfectly. I am pretty sure it has something to do with the sprites because without them everything works perfectly.
import pygame

BulletX = x + 10
BulletY = y - 15
color = (250,210,240)
ship_img = pygame.image.load('spaceship.png')
ship = pygame.transform.scale(ship_img,(32,32))
bullet_img = pygame.image.load('bullet (2).png')

window.blit(ship,(x,y))
pygame.draw.rect(window,color,pygame.rect(200,200,30,30))

if(BulletY <= -10):
BulletY = y - 10
BulletX = x + 10

The only problem with your code is a lowercase 'r' instead of of uppercase one. Change the appropriate line to:
pygame.draw.rect(window, color, pygame.Rect(200,200,30,30) )
and have fun implementing the collision.

Hi there and thank you for your time reading this.
This is related to the project I'm making. It's a reaction test game. Basically, Arcade buttons with LEDs light up, and players need to press them to score points. Whack-a-Mole style.
The game is timed, 30 seconds. But instead of using a numerical timer, I'm using a progress bar moving across the screen to indicate the remaining time instead.
image below:
game screenshot
I added this as an image blit in the code, but it doesn't refresh correctly. You can see it only at the start of the game, and when players press a button.
It needs to be constantly blitting across the screen.
Maybe I'm just missing something or my indentation is wrong?
Would really appreciate any inputs on this.
Main game loop code is below:
# MAIN GAME SEQUENCE CODE ---------------------------------------------------------------------------------------------
# Setup Pygame refresh rate to 120 fps
clock.tick(60)
while game_running:
# Idle Screen
idle_scrn()
# Instructions
inst_seq()
# GAME PLAY SECTION --------
score = 0
time_Out = 0
leds.off()
start_Time = pygame.time.Clock()
start = int(time.time())
time_move = -500
random_num = random.randint(0, 11)
leds.on(random_num)
print(random_num)
while time_Out != 30:
screen.blit(Timebar, (time_move,1000))
time_move += 50
pygame.display.update()
for event in pygame.event.get():
print("For Event started, Game screen started")
screen.fill((255,255,255))
screen.blit(Game_screen[6], (0,0))
score_textback = score_fontback.render("00", 3, (199,199,199))
score_text = score_font.render(str(score), 3, (255,37,24))
ctr = 1110
if score >= 10:
ctr -= 155
center_pos = (ctr, 580)
score_rect = score_text.get_rect(center = center_pos)
screen.blit(score_textback, (645, 390))
screen.blit(score_text, score_rect)
if event.type == pygame.JOYBUTTONDOWN:
print("If for event JOYBUTTONDOWN")
if event.button == random_num:
B = event.button
print(B, " button pressed, CORRECT")
leds.off()
butt_Sound.play()
random_num = random.randint(0, 11)
leds.on(random_num)
score += 1
pygame.display.update()
current_Time = int(time.time())
time_Out = current_Time - start
#pygame.display.update()
#print("TIMER: ", time_Out)
#print(type(start_Time))
#print(current_Time)
#print(type(current_Time))
#pygame.display.update()
# FINAL SCORE ------------------------
final_Score()
exit()
The image is Timebar. in the code, we move it 50 pixels across the screen in every refresh.
Thank you in advance.
Here's a minimal example, perhaps you'll find it useful:
import pygame
pygame.init()
width, height = 640, 480
screen = pygame.display.set_mode((width, height))
fps = 60
clock = pygame.time.Clock()
progress_width = 0 # initialse progress tracker
total_time = 0
target_time = 10_000 # ten seconds in milliseconds
finished = False
while not finished:
# Handle Events
for event in pygame.event.get():
if event.type == pygame.QUIT:
finished = True
elif event.type == pygame.KEYDOWN:
progress_width = 0 # reset progress
total_time = 0
# Update Game State
dt = clock.tick(fps) # limit FPS and return time since last call
total_time += dt
progress_width += width * dt / target_time # scale bar width
progress_rect = pygame.Rect(0, height-20, int(progress_width), 20)
# Draw Background
screen.fill(pygame.Color("black"))
# Draw Sprites
pygame.draw.rect(screen, pygame.Color("red"), progress_rect)
# Update Display
pygame.display.flip()
# Display the elapsed time in the title bar
pygame.display.set_caption(f"Simple Progress {total_time:,d} ms")
pygame.quit()
It calculates the time elapsed and updates the progress bar width. It takes ten seconds to fill the screen width and pressing a key resets the progress.
Your main loop should look something like:
Handle Events
Update Game State
Draw sprites
Update Screen
If you're trying to update the screen or handle events in multiple places, things get confusing pretty quickly.

Im trying to move a sprite in the direction of an angle in pygame, using the left & right arrow keys to change the direction of the sprite but when I press the up key, the sprite just moves right.

It just isnt working & I dont know why.
You have to calculate the vel_x and vel_y in the while loop.
while not closed_flag:
closed_flag = game_loop_inputs()
keybd_tupl = pygame.key.get_pressed()
if keybd_tupl[K_UP]:
circle_hitbox["pos"] = (circle_hitbox["pos"][0] + vel_x, circle_hitbox["pos"][1] + vel_y)
print(vel_y)
if keybd_tupl[K_LEFT]:
circle_hitbox["angle"] -= 1.0
if keybd_tupl[K_RIGHT]:
circle_hitbox["angle"] += 1.0
# `math.radians` can be used instead of `* (math.pi / 180)`
vel_x = speed * math.cos(math.radians(circle_hitbox["angle"]))
vel_y = speed * math.sin(math.radians(circle_hitbox["angle"]))
Also, pass the negative angle to pygame.transform.rotate in the game_loop_render function:
rotated_damage = pygame.transform.rotate(circle_hitbox["damage"], -circle_hitbox["angle"])
The rotation probably still doesn't look right (I'm using some replacement images and they don't rotate correctly). Take a look at this answer if you want to know how to rotate pygame sprites and images around their center in pygame.

This is my first time using pygame and I apologize for possible misunderstandings and 'silly' questions. I am developing a breaking game, consisting of a ball ,a paddle and a wall of bricks. So far I ve the ball, and that s fine. I am trying to implement my code in order to get the wall, but I am missing something and it doesn t show up on the screen when I run it. Could anyone help me? The bricks are 50x60, 3 rows. Thank you in advance. (If anyone would also recommend something about creating the paddle and making the ball stick to it, that would be highly appreciated.)
