パイゲームでスプライトが別のスプライトに触れているかどうかを調べるには

Question

私は既にこの質問をしていますが、私のコードは非常に異なり、解決方法は私の問題には当てはまりません。

私は果物を「つかまえる」目的があるゲームを作ろうとしています。しかし、私のバスケットが果物に触れるたびに、フルーツはバスケットを通り過ぎて行きます。ここに私のコードは次のとおりです。

import pygame 
import time 
import random 
pygame.init() 
display_width = 800 
display_height = 600 
black = (0,0,0) 
white = (255,255,255) 
red = (255,0,0) 
car_width = 64 
gameDisplay = pygame.display.set_mode((display_width,display_height)) 
pygame.display.set_caption('Avoid The Falling Objects') 
clock = pygame.time.Clock() 
carImg = pygame.image.load('basket.png') 
appleImg = pygame.image.load('apple.png') 
score = 0 
def things(thingx, thingy): 
    #pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])\ 
    gameDisplay.blit(appleImg, (thingx,thingy)) 
def car(x,y): 
    gameDisplay.blit(carImg, (x,y)) 
def text_objects(text, font): 
    textSurface = font.render(text, True, black) 
    return textSurface, textSurface.get_rect() 
def message_display(text): 
    largeText = pygame.font.Font('freesansbold.ttf',40) 
    TextSurf, TextRect = text_objects(text, largeText) 
    TextRect.center = ((display_width/2),(display_height/2)) 
    gameDisplay.blit(TextSurf, TextRect) 
    pygame.display.update() 
    time.sleep(2) 
    game_loop() 
def crash(): 
    message_display(('You dropped a fruit! Your score was: {}').format(score)) 
def game_loop(): 
    score = 0 
    x = (display_width * 0.45) 
    y = (display_height * 0.8) 
    x_change = 0 
    thing_startx = random.randrange(0, display_width) 
    thing_starty = -600 
    thing_speed = 7 
    thing_width = 100 
    thing_height = 100 
    gameExit = False 
    while not gameExit: 
     for event in pygame.event.get(): 
      if event.type == pygame.QUIT: 
       pygame.quit() 
       quit() 
      if event.type == pygame.KEYDOWN: 
       if event.key == pygame.K_LEFT: 
        x_change = -5 
       elif event.key == pygame.K_RIGHT: 
        x_change = 5 
      if event.type == pygame.KEYUP: 
       if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT: 
        x_change = 0 
     x += x_change 
     gameDisplay.fill(white) 
     things(thing_startx, thing_starty) 
     thing_starty += thing_speed 
     car(x,y) 
     if x > display_width - car_width or x < 0 - car_width: 
      crash() 
     if thing_starty > display_height: 
      crash() 
     if y < thing_starty+thing_height: 
      print('y crossover') 
      if x > thing_startx and x < thing_startx + thing_width or x + car_width > thing_startx and x + car_width < thing_startx: 
       score += 1 
       thing_starty = -100 
       thing_startx = random.randrange(0, display_width) 
     pygame.display.update() 
     clock.tick(60) 
game_loop() 
pygame.quit() 
quit()

あなたが衝突をチェックするpygame.Rect()とcolliderect()を使用することができます。

DISPLAY_WIDTH = 800 
DISPLAY_HEIGHT = 600 

BLACK = (0, 0, 0) 
WHITE = (255, 255, 255) 
RED = (255, 0, 0) 

CAR_WITDH = 64 

# --- functions --- (lower_case names) 

def text_objects(text, font): 
    text_image = font.render(text, True, BLACK) 
    return text_image, text_image.get_rect() 

def message_display(text): 

    large_font = pygame.font.Font('freesansbold.ttf',40) 
    text_image, text_rect = text_objects(text, large_font) 
    text_rect.center = screen_rect.center 

    screen.blit(text_image, text_rect) 
    pygame.display.update() 

    pygame.time.delay(2000) 

def crash(score): 
    message_display(('You dropped a fruit! Your score was: {}').format(score)) 

def reset_positions(): 

    car_rect.x = DISPLAY_WIDTH * 0.45 
    car_rect.y = DISPLAY_HEIGHT * 0.8 

    apple_rect.x = random.randrange(0, DISPLAY_WIDTH) 
    apple_rect.y = -600 

def game_loop(): 
    score = 0 

    x_change = 0 

    apple_speed = 7 

    reset_positions()

        x_change = 5

     car_rect.x += x_change 
     apple_rect.y += apple_speed 

     if car_rect.right > DISPLAY_WIDTH or car_rect.left < 0: 
      crash(score) 
      reset_positions() 
      score = 0 

     if apple_rect.bottom > DISPLAY_HEIGHT: 
      crash(score) 
      reset_positions() 
      score = 0 

     if car_rect.colliderect(apple_rect): 
      score += 1 
      car_rect.y -= 10 
      apple_rect.x = random.randrange(0, DISPLAY_WIDTH-apple_rect.width) 
      apple_rect.y = -600 

     # --- draws (without updates) --- 

     screen.fill(WHITE) 
     screen.blit(apple_image, apple_rect) 
     screen.blit(car_image, car_rect) 
     pygame.display.update() 

     # --- FPS --- 

     clock.tick(60)

pygame.init() 

screen = pygame.display.set_mode((DISPLAY_WIDTH, DISPLAY_HEIGHT)) 
screen_rect = screen.get_rect() 

pygame.display.set_caption('Avoid The Falling Objects') 

# - objects - 

car_image = pygame.image.load('basket.png')

apple_image = pygame.image.load('apple.png')
