Pygame實現監聽鼠標示例詳解

pygame如何捕捉鼠標的活動

初始化參數

import pygame, sys
from pygame.locals import *


def print_text(font, x, y, text, color=(0, 0, 0)):
    """打印字體函數"""
    img_text = font.render(text, True, color)
    screen.blit(img_text, (x, y))


pygame.init()
screen = pygame.display.set_mode((400, 400))
pygame.display.set_caption("監聽鼠標活動")


while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()

    screen.fill((255, 255, 255))

    pygame.display.update()

鼠標移動

event.type 事件為MOUSEMOTION,則為鼠標移動,event.pos可以獲取當前位置,event.rel鼠標的偏移。

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

我們將位置輸出出來,定義鼠標的位置和鼠標的偏移量

mouse_x = mouse_y = 0
move_x = move_y = 0
	print_text(font1, 0, 0, "鼠標事件")
    print_text(font1, 0, 20, "鼠標的位置:" + str(mouse_x) + "," + str(mouse_y))
    print_text(font1, 0, 40, "鼠標的偏移:" + str(move_x) + "," + str(move_y))

鼠標點擊位置

MOUSEBUTTONDOWN和MOUSEBUTTONUP記錄鼠標的按下和放開動作

mouse_down = mouse_up = 0
mouse_down_x = mouse_down_y = 0
mouse_up_x = mouse_up_y = 0

輸出鼠標位置及其對用的按鈕

pygame.mouse.get_pressed() 可以監聽鼠標的三個按鍵。

    x, y = pygame.mouse.get_pos()
    print_text(font1, 0, 180, "鼠標位置:" + str(x) + "," + str(y))

    b1, b2, b3 = pygame.mouse.get_pressed()
    print_text(font1, 0, 200, "按鈕:" + str(b1) + "," + str(b2) + "," + str(b3))

    """打印字體函數"""
    img_text = font.render(text, True, color)
    screen.blit(img_text, (x, y))


pygame.init()
# 字體
font1 = pygame.font.SysFont("方正粗黑宋簡體", 18)

        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEMOTION:
            mouse_x, mouse_y = event.pos
            move_x, mouse_y = event.rel
        elif event.type == MOUSEBUTTONDOWN:
            mouse_down = event.button
            mouse_down_x, mouse_down_y = event.pos
        elif event.type == MOUSEBUTTONUP:
            mouse_up = event.button
            mouse_up_x, mouse_up_y = event.pos

    screen.fill((255, 255, 255))
    print_text(font1, 0, 0, "鼠標事件")
    print_text(font1, 0, 20, "鼠標的位置:" + str(mouse_x) + "," + str(mouse_y))
    print_text(font1, 0, 40, "鼠標的偏移:" + str(move_x) + "," + str(move_y))
    print_text(font1, 0, 60, "鼠標按下:" + str(mouse_down)
               + "在" + str(mouse_down_x) + "," + str(mouse_down_y))
    print_text(font1, 0, 80, "鼠標松開:" + str(mouse_up)
               + "在" + str(mouse_up_x) + "," + str(mouse_up_y))
    x, y = pygame.mouse.get_pos()
    print_text(font1, 0, 180, "鼠標位置:" + str(x) + "," + str(y))

    b1, b2, b3 = pygame.mouse.get_pressed()
    print_text(font1, 0, 200, "按鈕:" + str(b1) + "," + str(b2) + "," + str(b3))
    pygame.display.update()
