Example Analysis of Monitoring Mouse by Pygame

Pygame implements the example analysis of monitoring mouse. In view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Initialization parameters import pygame, sysfrom pygame.locals import * def print_text (font, x, y, text, color= (0,0,0): "" print font function "" img_text = font.render (text, True, color) screen.blit (img_text, (x, y) pygame.init () screen = pygame.display.set_mode Pygame.display.set_caption ("listen for mouse activity") while True: for event in pygame.event.get (): if event.type = = QUIT: pygame.quit () sys.exit () screen.fill ((255,255,255)) pygame.display.update ()

Mouse movement

The event.type event is MOUSEMOTION, then the mouse is moved, and the event.pos can get the current position, the offset of the event.rel mouse.

Event.type = = MOUSEMOTION: event.pos event.rel

We output the position to define the position of the mouse and the offset of the mouse

Mouse_x = mouse_y = 0move_x = move_y = 0 print_text (font1, 0,0, "mouse event") print_text (font1, 0,20, "mouse position:" + str (mouse_x) + "," + str (mouse_y)) print_text (font1, 0,40, "mouse offset:" + str (move_x) + "," + str (move_y)

Mouse click location

MOUSEBUTTONDOWN and MOUSEBUTTONUP record mouse press and release actions

Mouse_down = mouse_up = 0mouse_down_x = mouse_down_y = 0mouse_up_x = mouse_up_y = 0

Output mouse position and corresponding buttons

Pygame.mouse.get_pressed () can listen for the three mouse buttons.

X, y = pygame.mouse.get_pos () print_text (font1, 0180, "mouse position:" + str (x) + "," + str (y)) b1, b2, b3 = pygame.mouse.get_pressed () print_text (font1, 0200, "button:" + str (b1) + "," + str (b2) + "," + str (b3))
