在 Pygame 中使用 pygame.Rect.colliderect 添加碰撞

先决条件：在 Pygame 中绘制形状，pygame 简介

在本文中，我们将使用 pygame.Rect.colliderect 在Python使用 Pygame 在形状中添加碰撞。

我们可以使用 colliderect() 轻松地在 Pygame 形状中添加碰撞。为此，我们将绘制两个矩形，然后我们将检查矩形是否发生碰撞。

Syntax: pygame.Rect.colliderect(rect1, rect2)

Parameters: It will take two rects as its parameters.

Returns: Returns true if any portion of either rectangle overlap.

示例 1：以一种方式在形状中添加碰撞的简单示例

Python3

# Importing the pygame module
import pygame
from pygame.locals import *
 
# Initiate pygame and give permission
# to use pygame's functionality
pygame.init()
 
# Create a display surface object
# of specific dimension
window = pygame.display.set_mode((600, 600))
 
# Creating a new clock object to
# track the amount of time
clock = pygame.time.Clock()
 
 
# Creating a new rect for first object
player_rect = Rect(200, 500, 50, 50)
 
# Creating a new rect for second object
player_rect2 = Rect(200, 0, 50, 50)
 
# Creating variable for gravity
gravity = 4
 
# Creating a boolean variable that
# we will use to run the while loop
run = True
 
# Creating an infinite loop
# to run our game
while run:
 
    # Setting the framerate to 60fps
    clock.tick(60)
 
    # Adding gravity in player_rect2
    player_rect2.bottom += gravity
 
    # Checking if player is colliding
    # with platform or not using the
    # colliderect() method.
    # It will return a boolean value
    collide = pygame.Rect.colliderect(player_rect, p
                                      layer_rect2)
 
    # If the objects are colliding
    # then changing the y coordinate
    if collide:
        player_rect2.bottom = player_rect.top
 
    # Drawing player rect
    pygame.draw.rect(window, (0,   255,   0),
                     player_rect)
    # Drawing player rect2
    pygame.draw.rect(window, (0,   0,   255),
                     player_rect2)
 
    # Updating the display surface
    pygame.display.update()
 
    # Filling the window with white color
    window.fill((255, 255, 255))

输出：
