pygame.mouse動作測試

網路資源很多,很快就搜尋到別人寫的pygame.mouse的code.
https://sivasantosh.wordpress.com/2012/07/18/mouse-handling-in-pygame/
但看來得需要視窗化的環境才能運作,且運作範圍在開啟的視窗內.難怪我上一篇blog是失敗的…

下圖是執行畫面.右邊的視窗是screen= pygame.display.set_mode(size) 開啟的視窗
滑鼠的按鍵動作 以及 指標位置 需在視窗內才會有反應.
 
原始碼如下

import pygame, sys

white= (255, 255, 255)
black= (0, 0, 0)

pygame.init()
pygame.display.set_caption('Mouse Example')
size= [640, 480]
screen= pygame.display.set_mode(size)
clock= pygame.time.Clock()

# make os mouse pointer icon invisible
pygame.mouse.set_visible(False)

while True:
   for event in pygame.event.get():
       if event.type== pygame.QUIT:
            pygame.quit()
            sys.exit()
       # print if mouse is pressed.
       # get_pressed() tells you which mouse button is pressed
       if event.type== pygame.MOUSEBUTTONDOWN:
           print ('mouse pressed',pygame.mouse.get_pressed())
       # print if mouse is released.
       elif event.type== pygame.MOUSEBUTTONUP:
           print ('mouse released', pygame.mouse.get_pressed())
       # print if mouse is in motion.
       # get_rel() - Returns the amount of movement in X and Y since the previous call to this function.
       if event.type== pygame.MOUSEMOTION:
           print ('mouse is moving', pygame.mouse.get_rel())
    screen.fill(white)

   # draw a circle around the mouse pointer
    pos= (pygame.mouse.get_pos()[0], pygame.mouse.get_pos()[1])
    pygame.draw.circle(screen, black, pos, 10, 0)

    pygame.display.update()

    clock.tick(20)
