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

Closed 2 years ago.
I am trying to write a pygame program where the user dodges objects falling from the top of the screen. However, when I run, collideRect activates too early. Any suggestions?

I made a surface for the player health and drew it on the screen. Then I made an if statement checking to see if the player X position was == to the enemy X position and if it was the player health would continuously decrease. I know it was decreasing because I was having it print out the player health afterwards in the console and everything was good but the health on the screen would not change. What am I doing wrong?
I am a newbie at pygame and a beginner in python therefore my code is not written in the best way...
Sorry the code is very long but the # should show everything...
import pygame
from sys import exit
from time import sleep
pygame.init()
clock = pygame.time.Clock()
screen = pygame.display.set_mode((1200, 535))
background = pygame.image.load("background1.jpg")
background = pygame.transform.rotozoom(background, 0, 2)
# Player
player_surf = pygame.image.load("player_sprites/player_right.png").convert_alpha()
player_rect = player_surf.get_rect(bottomright = (575, 470))
player_surf = pygame.transform.rotozoom(player_surf, 0, 2.5).convert_alpha()
# Health...
health = 50
health_font = pygame.font.Font('Pixeltype.ttf', 50)
health_display = health_font.render(f"Health {health}", True, (0, 0, 0))
# Enemy #1
enemy1_surf = pygame.image.load("enemy1sprites/enemy1_right.png").convert_alpha()
enemy1_rect = enemy1_surf.get_rect(bottomleft = (1100, 462))
enemy1_surf = pygame.transform.rotozoom(enemy1_surf, 0, 2.5).convert_alpha()
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
screen.blit(background, (0, 0))
screen.blit(player_surf, player_rect)
screen.blit(enemy1_surf, enemy1_rect)
screen.blit(health_display, (550, 75))
# Player Movement
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
player_surf = pygame.image.load("player_sprites/player_left.png")
player_surf = pygame.transform.rotozoom(player_surf, 0, 2.5)
player_rect.x -= 4
if event.key == pygame.K_RIGHT:
player_surf = pygame.image.load("player_sprites/player_right.png")
player_surf = pygame.transform.rotozoom(player_surf, 0, 2.5)
player_rect.x += 4
if player_rect.x >= 1075:
player_rect.x = 1075
elif player_rect.x <= 0:
player_rect.x = 0
wave_one = True
# Enemy 1 AI
if player_rect.x != enemy1_rect.x:
if player_rect.x > enemy1_rect.x:
enemy1_surf = pygame.image.load("enemy1sprites/enemy1_right.png")
enemy1_surf = pygame.transform.rotozoom(enemy1_surf, 0, 2.5)
enemy1_rect.x += 1
elif player_rect.x < enemy1_rect.x:
enemy1_surf = pygame.image.load("enemy1sprites/enemy1_left.png")
enemy1_surf = pygame.transform.rotozoom(enemy1_surf, 0, 2.5)
enemy1_rect.x -= 1
# Collision with enemy
if player_rect.x == enemy1_rect.x:
health -= 0.005
print(health)
pygame.display.update()
clock.tick(60)
I expected it to continuously update the health_display but It did not.
Have you tried updating / re-rendering the text on screen? From your code, it appears that the health is only printed when updated, not shown in the game.

Hello i need to programm a Game with pygame for school. I nearly finish the Game but when i want to Press the "C" button in the Gameover loop then nothing happends and the game will not restart.
unti i spam the "C" Button. I dont think that there is a problem with the detection of pressing the button because i made a print command thatalways prints something when i press the "C" Button and it always print something out.
I hope you can help me with the Problem :)

Played your game got highscore of 22 oh I mean I read the code and and I debugged it
Well actually playing was the debugging haha. The problem is that after you press C game restarts as it should but the enemy which hit you is not removed and it instantly kills you again and moves tiny bit lower. By spamming C you move it out of screen and game continues
Simple fix to reset enemy pose when C is pressed
if event.key == ord("c"):
enemie_pos_y = 30 # Reset enemy pose
Keep up the good work!
I've got a variable that increases when the user presses a button.
When the user presses another button, I'd like to set that variable to 0,
but not instantly-- I'd like it to tick down over the course of a few seconds.
During this time I'd like the user to be able to perform other actions-- hence why I'm not using sleep.
I've looked at using pygame's events, time.clock, etc., but I can't seem to get this to work. Here is what I've tried so far:
import pygame, sys, math
from pygame.locals import *
pygame.init()
pygame.font.init()
scrw = 640
scrh = 480
screen = pygame.display.set_mode((scrw, scrh))
ttwist = 0
recentering = False
fps = 15
clock = pygame.time.Clock()
my_font = pygame.font.SysFont("arial", 12)
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
pressed = pygame.key.get_pressed()
if not recentering:
if pressed[pygame.K_d]:
ttwist +=1
if pressed[pygame.K_a]:
ttwist -=1
RECENTERTORSOEVENT = USEREVENT
if event.type == pygame.KEYDOWN and event.key == pygame.K_BACKSLASH:
recentering = True
pygame.time.set_timer(RECENTERTORSOEVENT, 1000*abs(ttwist))
if ttwist == 0:
recentering = False
if event.type == USEREVENT:
if ttwist < 0:
ttwist += 1
elif ttwist > 0:
ttwist -= 1
drawtext = my_font.render("TTWIST:"+str(ttwist), True, (255,255,255),(0,0,0))
screen.blit(drawtext,(10,130))
pygame.display.update()
clock.tick(fps)
What am i doing wrong?
You are on the right track, but some parts of the code need to be changed:
All the if event.type == ... blocks should be inside of the event loop.
RECENTERTORSOEVENT = USEREVENT should be defined above the while loop (but that doesn't cause problems).
You're setting the time interval for the RECENTERTORSOEVENT way too high: 1000*abs(ttwist). That means, if the ttwist is 10, you're setting it to 10.000 ms (10 seconds). Just set it to a constant value like 100 ms.
When the ttwist is recentered, call pygame.time.set_timer(RECENTERTORSOEVENT, 0) to stop the timer.
Fill the screen each frame screen.fill((30, 30, 30)), otherwise you see artifacts because the font surface keeps changing its size.
import sys
import pygame
pygame.init()
screen = pygame.display.set_mode((640, 480))
my_font = pygame.font.SysFont('arial', 22)
clock = pygame.time.Clock()
ttwist = 0
RECENTERTORSOEVENT = pygame.USEREVENT
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_r:
print('recentering')
# Start to add the USEREVENT every 100 ms.
pygame.time.set_timer(RECENTERTORSOEVENT, 100)
elif event.type == RECENTERTORSOEVENT:
ttwist += 1 if ttwist < 0 else -1
if ttwist == 0:
print('done')
# Stop to add the USEREVENT to the queue.
pygame.time.set_timer(RECENTERTORSOEVENT, 0)
pressed = pygame.key.get_pressed()
if pressed[pygame.K_d]:
ttwist += 1
if pressed[pygame.K_a]:
ttwist -= 1
screen.fill((30, 30, 30))
drawtext = my_font.render(
'TTWIST: {}'.format(ttwist), True, (255, 255, 255))
screen.blit(drawtext, (10, 130))
pygame.display.update()
clock.tick(30)
ttwist += 1 if ttwist < 0 else -1 is a conditional expression and does basically the same as:
if ttwist < 0:
ttwist += 1
elif ttwist > 0:
ttwist -= 1
