[英]Pygame not drawing rectangle while clicking
我是 pygame 的新手,我正在制作一個簡單的游戲。 在這段代碼中,我試圖在鼠標位於某個 position 時繪制一個矩形,但是當我打印任何內容時它沒有繪制它
import pygame
pygame.init()
res = (600,600)
screen = pygame.display.set_mode(res)
pygame.display.set_caption("Tic Tac Toe")
background = (255,150,150)
color_light = (170,170,170)
color_dark = (100,100,100)
hover_color = (255, 204, 203)
width = screen.get_width()
height = screen.get_height()
def draw_line():
pygame.draw.rect(screen, line_color, (190,10,10,580))
pygame.draw.rect(screen, line_color, (390, 10, 10, 580))
pygame.draw.rect(screen, line_color, (10, 200, 580, 10))
pygame.draw.rect(screen, line_color, (10, 390, 580, 10))
def highlight():
if 10 <= mouse[0] <= 10+180 and 10 <= mouse[1] <= 10+190:
pygame.draw.rect(screen, hover_color, (10, 10, 180, 190)) # X,Y,WIDTH,HEIGHT
if 205 <= mouse[0] <= 205+180 and 10 <= mouse[1] <= 10+190:
pygame.draw.rect(screen, hover_color, (200, 10, 190, 190)) # X,Y,WIDTH,HEIGHT
if 400 <= mouse[0] <= 400+190 and 10 <= mouse[1] <= 10+190:
pygame.draw.rect(screen, hover_color, (400, 10, 190, 190)) # X,Y,WIDTH,HEIGHT
if 10 <= mouse[0] <= 10+180 and 210 <= mouse[1] <= 210+180:
pygame.draw.rect(screen, hover_color, (10, 210, 180, 180)) # X,Y,WIDTH,HEIGHT
if 200 <= mouse[0] <= 200+180 and 210 <= mouse[1] <= 210+180:
pygame.draw.rect(screen, hover_color, (200, 210, 200, 180)) # X,Y,WIDTH,HEIGHT
if 400 <= mouse[0] <= 400+190 and 210 <= mouse[1] <= 210+180:
pygame.draw.rect(screen, hover_color, (400, 210, 190, 180)) # X,Y,WIDTH,HEIGHT
if 10 <= mouse[0] <= 10+180 and 400 <= mouse[1] <= 400+200:
pygame.draw.rect(screen, hover_color, (10, 400, 180, 190)) # X,Y,WIDTH,HEIGHT
if 200 <= mouse[0] <= 200+190 and 400 <= mouse[1] <= 400+200:
pygame.draw.rect(screen, hover_color, (200, 400, 190, 190)) # X,Y,WIDTH,HEIGHT
if 400 <= mouse[0] <= 400+190 and 400 <= mouse[1] <= 400+190:
pygame.draw.rect(screen, hover_color, (400, 400, 190, 190)) # X,Y,WIDTH,HEIGHT
while True:
screen.fill(background)
mouse = pygame.mouse.get_pos()
for ev in pygame.event.get():
if ev.type == pygame.QUIT:
pygame.quit()
if ev.type == pygame.MOUSEBUTTONDOWN:
if 10 <= mouse[0] <= 10 + 180 and 10 <= mouse[1] <= 10 + 190:
pygame.draw.rect(screen,background,(10,10,180,190))
pygame.display.update()
line_color = (212, 212, 255)
draw_line()
highlight()
pygame.display.update()
要使矩形永久化,您需要在應用程序循環中繪制矩形。 該事件在單個幀中僅發生一次。 添加一個變量clicked = False
。 在事件發生時設置變量。 並根據變量的 state 繪制矩形:
clicked = False
while True:
screen.fill(background)
mouse = pygame.mouse.get_pos()
for ev in pygame.event.get():
if ev.type == pygame.QUIT:
pygame.quit()
if ev.type == pygame.MOUSEBUTTONDOWN:
if 10 <= mouse[0] <= 10 + 180 and 10 <= mouse[1] <= 10 + 190:
clicked = True
line_color = (212, 212, 255)
draw_line()
highlight()
if clicked:
pygame.draw.rect(screen,background,(10,10,180,190))
pygame.display.update()
簡化您的代碼:
為矩形創建一個pygame.Rect
對象列表
rect_list = [pygame.Rect(10, 10, 180, 190), ...]
為所述字段創建列表
clicked_list = [0 for _ in rect_list]
使用collideponit
測試鼠標是否在矩形上:
for rect in rect_list: if rect.collidepoint(mouse): pygame.draw.rect(screen, hover_color, rect)
使用collidepoint
判斷一個字段是否被點擊,並改變該字段的state
if ev.type == pygame.MOUSEBUTTONDOWN: for i, rect in enumerate(rect_list): if rect.collidepoint(ev.pos): clicked_list[i] = 1
根據其 state 在循環中繪制該字段:
for i, rect in enumerate(rect_list): if clicked_list[i]: pygame.draw.rect(screen,background,rect)
