Common methods of Pygame

''' 
import pygame 

# Initialize the pygame library and prepare the computer hardware for 
pygame.init() 


# ---------- Window related operations ----------- 
# Create a window 
window = pygame .display.set_mode([window width, window height]) 

# set the window title 
pygame.display.set_caption("window title") 

# load the resource image and return the image object 
image = pygame.image.load("res/game.ico ") 
# Set the window icon 
pygame.display.set_icon(image) 


# Specify the coordinates and draw the picture to the window 
window.blit(image, (0, 0)) 


# ----------Image related operations- ---------- 
# Load the image file and return the image object 
image = pygame.image.load("image path") 

# Get the image rectangle object -> Rect(x, y, width, height) 
# Default In this case, the coordinates of the upper left corner are (0, 0) 
rect = image.get_rect(centerx=x, centery=y) 


# On the basis of the original position, move the specified offset (x, y increase) 
rect.move_ip(num1, num2)


# Determine whether the two rectangles intersect, and the intersection returns True, otherwise returns False 
flag = pygame.Rect.colliderect(rect1, rect2) 

# Scale the image object according to the specified width and height, and return a new image object 
trans_image = pygame.transform.scale( image, (WINDOWWIDTH, WINDOWHEIGHT)) 


# ----------Event related operations----------- 
# Common event types: 
# QUIT closes the window 
# KEYDOWN keyboard key 
# Get all the current Keep pressing bools_tuple 


# Get a list of all events 
event_list = pygame.event.get() 

for event in event_list: 
    # 1. Mouse click to close the window event 
    if event.type == pygame.QUIT: 
        print("Close the window") 
        sys .exit() 

    # 2. Keyboard press event 
    if event.type == pygame.KEYDOWN: 

        # Determine whether the key pressed by the user is the a key 
        if event.key == pygame.K_a: 
            print("Pressed a ")

        if event.key == pygame.k_UP: 
            print("Press the up arrow key") 


# 3. Get the status of all keys on the current keyboard (pressed, not pressed), return a bool tuple 
pressed_keys = pygame.key.get_pressed () 
(0, 0, 0, 0, 1, 0, 0, 0, 0) 

if pressed_keys[pygame.K_w] or pressed_keys[pygame.K_UP]: 
    print("W key is pressed, or the arrow key is up") 


# ----------Sound related operations ----------- 
# Load background music 
pygame.mixer.music.load("./res/bg2.ogg") 
# Loop playback Background music 
pygame.mixer.music.play(-1) 
# Stop background music 
pygame.mixer.music.stop() 

# Load sound effects 
boom_sound = pygame.mixer.Sound("./res/baozha.ogg") 
# Play sound effects 
boom_sound.play() 

boom_sound.stop() 


Three primary colors: Red Green Blue 

0 ~ 255 

# -------- Text display operation 

# Set font and size
font = pygame.font.SysFont('SimHei', 42) 

# render(text(text content), antialias(antialiasing), color(RGB)), return text object 
textobj = font.render("Airplane Wars", 1 , (255, 255, 255)) 

# Set the text rectangle object position 
textrect = textobj.get_rect(centerx=300, centery=300) 

# Draw the specified text object at the specified position 
window.blit(textobj, textrect)
