How do I delete rect object from screen once player collides with it?
(1 answer)
Closed 23 days ago.
I am new at using objects in python and brand new at Pygame. I am trying to make a game where a player moves around the screen eating objects. However, I am unable to get the consumed objects to disappear, the moving object is smudging and not transparent. The Downward and Rightward movement keys also produce no result.
This is the code for the movement:
def move(self):
if self.dir != '':
if self.dir == 'd' and self.rect.bottom < self.height:
self.rect.top += self.speed
if self.dir == 'u' and self.rect.top > 0:
self.rect.top -= self.speed
if self.dir == 'l' and self.rect.left > 0:
self.rect.left -= self.speed
if self.dir == 'r' and self.rect.right < self.width:
self.rect.right += self.speed
the code for image transparency:
self.surface = pygame.image.load("images/player.png").convert_alpha()
This is how I am drawing the player and the consumable:
def draw(self):
self.screen.blit(self.surface, self.rect)
and the main update code that is inside the game loop:
def update(self):
for f in self.foods[:]:
if self.player.rect.colliderect(f.rect):
self.foods.remove(f)
self.foods.append(Consumable(
self.screen, WIDTH*random.randint(1, 9)//10, HEIGHT*random.randint(1, 9)//10))
self.eaten += 1
for f in self.foods:
f.draw()
if self.eaten == 10:
self.won = True
self.player.move()
self.player.draw()
pygame.display.update()
pygame.display.flip()
This is the full game code:

How to adjust the direction of movement of bullet sprites?

In my program, when the keys are pressed, the image of the ship is flipped. I decided to bind the direction of the bullets to the flags of the ship's position. But I ran into the problem that all bullets take the direction of the ship when they are already fired. I need to keep the coordinate of the sprite when it is drawn.

The problem here is that in Bullet.update, you use the current image of the rocket to determine in which direction the bullet is going. This means that any change of this image results in a change of direction. Instead of doing this, you should save the current direction upon creating a new Bullet instance and then use this saved direction to determine the direction of the rocket.
A possible implementation:
class Bullet(Sprite):

def __init__(self, screen, settings, rocket):
super().__init__()
self.screen = screen
self.settings = settings
self.rocket = rocket

I need to be able to pause the whole game, but only my car sprite pauses when I press the p key on my keyboard

I implemented a pause feature in my game in the while loop at the end of my code, but the problem is that only my car sprite pauses. I have tried a bunch of different ways setting up my pause code but none of the ways I arrange it seems to pause the whole game.
I want to be able to pause my whole game when I press the p key on my keyboard, not just my car sprite. Can someone please tell me how I can fix this code? The code that will pause the whole game will be nice. Please, the rearranged code that will pause the whole game will help. Also I don't just want the answer, I want a quick explanation of why only my car sprite would pause instead of the whole game.

Move your

below the for loop, like so:

all_sprites.draw(screen)
#update the display
pygame.display.update()
pygame.display.flip()
clock.tick(FPS)
pygame.quit()
The reason only your car sprite paused when you pressed the q key is because, as you can see in your original code here:
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
#pause game
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_p:
paused = not paused
if paused == True:
continue
you put the
if paused == True:
continue
inside the for loop, not the while loop, so the lines that move the car would be blocked, but the rest of the code within the while loop will still get executed.

How do you move a sprite up and down?

I've been at it for a while, and I cannot seem to figure out why my sprite is not moving up or down when the program is run.

I have tried different types of commands trying to figure out whether it's a variable or function problem. Also is there a way I can make it move without having to tap the key.

In the event loop you're checking if the event.type is pygame.K_w or pygame.K_s, but you have to check if the event.key is equal to these constants. Change
elif event.type == pygame.K_w:
starboy.move_up()
elif event.type == pygame.K_s:
starboy.move_down()
to:
elif event.key == pygame.K_w:
starboy.move_up()
elif event.key == pygame.K_s:
starboy.move_down()
You also forgot the parentheses behind starboy.update.

Closed 2 years ago.
so my issue is with my player class, I'm still trying to understand classes.
So, basically, I'm using this player movement code from one of Pyganim's examples but I can't seem to implement it into this player class of mine, probably because I don't really understand classes.
For starters. My player never gets displayed now, every thing worked before I tried to add classes. I've probably just over complicated things trying to use this movement. My code is:
import pygame, sys, random, pyganim
from pygame.locals import *
class Scene(object):
screen = pygame.display.set_mode((800, 600))
class Intro(Scene):
def __init__(self):
self.c = (32, 32, 100)
def draw(self):
Scene.screen.fill(self.c)
def update(self):
# since scenes are classes, they have a state that we can modify
r,g,b = self.c
r += 1
g += 1
b += 2
if r > 255: r = 0
if g > 255: g = 0
if b > 255: b = 0
self.c = r, g, b

# move to Menu-scene when space is pressed
if event.type == pygame.KEYDOWN:

class Menu(Scene):

Increasing Pygame Image size after collision?

So I'm just learning how to work with classes and getting them to work between each different class. I'm trying to design a game where the user moves around and picks up food and each time the user picks up a piece of food the size of the character increases. I've done something similar before but now that there are classes involved I seem to have a hard time finding which class this should be part of. I added within the sprite update method that if it collides with a cherry then the size of the player should increase by 5 pixels each time. using the code :
self.Player.surface = pygame.transform.scale(self.Player.surface, (pwidth+5, pheight+5))
self.rect = self.Player.surface.get_rect()
Each time the game runs the player size doesn't change and for some reason the game no longer ends after the player has eaten a certain amount of cherries so I was just wondering if I was using a wrong method of changing the size of the player perhaps there may be an easier way to do so? Heres the rest of the code incase it helps at all.

Surface.get_rect() will always return a rect starting at (0,0), and you also are modifying SpritesGame.rect. I think you should change
self.rect = self.Player.surface.get_rect()
to
self.Player.rect.inflate_ip(5, 5)
