I've been redoing a lot of my game in order to make it more efficient, before I had functions for each level and it had about 300+ repeated lines of code for each level, I've taken it out however I'm trying to get level one to function properly now. Below is my code, any help as to how to get my code to play level1 when I run the game as right now it only displays the background screen and none of the enemies, platforms or the character.

I Think you should take a look at your "levels" Class.
Give it a proper init method, for example.
I got the game running by modifing the class as follows:
class levels():

self.all_sprites = pygame.sprite.Group()
self.platforms = pygame.sprite.Group()

self.all_sprites.add(bullet)

(seems like the indentation was not copied properly, everything below "class levels()" has to be indented 4 more spaces)
and adding
if __name__ == '__main__':
game = levels()
game.run()
at the bottom of the file.

How to detect collisions between two rectangular objects or images in pygame

How do I detect collision in pygame?
(5 answers)
Closed 2 years ago.
I have been trying to create a 2D platformer in pygame, and I have encountered a problem with the collision of the player sprite with the platform. I hope to implement full collision for the platforms, so that the player sprite will stop when it hits the platform from any direction. Currently, the sprite stops when it hits the top of the platforms, but if it collides with the bottom or sides of a platform it instantly jumps to the top of the platform. I have tried various things to solve this, but to no avail. Any help would be appreciated.
I have seperated my code into 3 files.
This is my main file:
import pygame
from settings import *

This is the code that is responsible for collision:
hits = pygame.sprite.spritecollide(self.player, self.platforms, False)
if hits:
self.player.pos.y = hits[0].rect.top
self.player.spd.y = 0
self.player.rect.midbottom = self.player.pos
I understand that the reason why the sprite jumps to the top of the platform is due to these lines of code:
if hits:
self.player.pos.y = hits[0].rect.top
However, I don't know how to implement full collision.
im trying to create a game for class. and i want to add a start screen to it but it doesnt seem to work.

You haven't defined a text_objects function. It looks like you meant the draw_text function that you declared above, but it doesn't quite do what you want either.
I'm guessing that what you meant to do was something like:
Create a text surface and a rectangle that represents the bounds of that surface
Move the rectangle to the middle of the screen (the width / 2 code)
Draw the text surface using that rectangle
You can modify the draw_text function you already have to return that stuff, since it seems to already calculate a bounding rectangle for the text and make a surface for that text as well.
When I try to load my game everything works except for the fact that it crashes and python doesn't respond. I can't see what I have missed.

Here is the error that happens if I force quit the app:
Traceback (most recent call last):

for event in pygame.event.get():
pygame.error: video system not initialized
pygame.quit doesn't quit the whole program, it just uninitializes the pygame modules. So the while loop in show_go_screen is still running and calls pygame.event.get(), but that doesn't work anymore after you've uninitialized everything and the pygame.error: video system not initialized is raised.
To quit the game call sys.exit() after pygame.quit(). Add import sys at the top of the file.
Also, to run the game I had to modify the event loop in show_go_screen and remove the first while running: loop:
def show_go_screen():
screen.blit(background, background_rect)
draw_text(screen, "SHMUP!", 64, WIDTH / 2, HEIGHT / 4)
draw_text(screen, "Arrow keys move, Space to fire", 22,

I am working on a game and I wanted to add an ammo box that randomly spawns. so far the box spawns as expected and if you move over it, it is removed and gives you 200+ ammo. However, it is only supposed to give 50 ammo. Then later in the game when the player goes back to that spot they continue to get more ammo. If I just sit there I end up getting 1000+ ammo.
Here is my ammo class:

The sprite is indeed removed but self.ammo which is called to check for collision is still working even after the sprite is removed. Here's what I'd do:
if self.ammo and player_rect.colliderect(self.ammo.rect):
self.ammo_amount += 50
self.all_sprites_list.remove(self.ammo)
self.ammo = None

So glitch number one:
only one of the boxers moves, I cant figure out why it only one of them is moving towards the player, all the boxers are meant to move towards the player as this is hoping to become a zombie shooter.
Glitch two:
At a random point the box that does move does stops moving in all directions but one, so lets say this happens when the box in in the center of the screen, if the player goes to the left of the box, nothing, but when the player moves to thr right of the player it moves right, but only right not up or down, and this seams to happen at soem point everytime.
Well thats it, hope you can help thanks heaps stackoverflow

Game().run()
Changes:
player can move but can leave screen
press space to pause game - but you can still move cursor and fire :)
bullet has max range - than it is removed
i change bullet vetor calculations because value was rounded to integer every frame and bullet trajectory was incorrect
bullet never change trajectory when player is moving
all code is in classes except some constant values. I add class Crosshair and Background
you can see how class (Player) handle events in event_handle
I use pygame.Rect() (screen.get_rect(), image.get_rect()) to get rect.top, rect.left, rect.center, rect.centerx, rect.topleft, etc.
There is still many things to do.
ps. if someone needs images 'ball1.png', 'ball2.png', 'ball3.png' to run this example you can find it in answer to
