我正在嘗試讓我的繪圖游戲在拖動鼠標的位置繪制一個圓圈，但這些圓圈的更新頻率不足以創(chuàng)建平滑的線條。我該如何解決這個問題？import pygamefrom random import randintwidth=800height=600pygame.init() #As necessary as import, initalizes pygameglobal gameDisplay gameDisplay = pygame.display.set_mode((width,height))#Makes windowpygame.display.set_caption('Demo')#Titles windowclock = pygame.time.Clock()#Keeps time for pygamegameDisplay.fill((0,0,255))class Draw: def __init__(self): self.color = (255, 0, 0) def update(self, x, y): self.x = x self.y = y pygame.draw.circle(gameDisplay, self.color, (self.x, self.y), (5))end = Falsedown = FalseLine = Draw()while not end: x, y = pygame.mouse.get_pos() #drawShape() #pygame.draw.rect(gameDisplay, (0,255,0), (10, 10, 4, 4)) for event in pygame.event.get(): if event.type == pygame.MOUSEBUTTONDOWN: down = True if event.type == pygame.MOUSEBUTTONUP: down = False if down: Line.update(x, y) if event.type == pygame.QUIT: end = True lastx, lasty = pygame.mouse.get_pos() pygame.display.update() clock.tick(60)pygame.quit()這就是我的問題

我建議從上一個鼠標位置到當前鼠標位置繪制一條線。另外，在線的起點和終點畫一個點。這會導致一個回合的開始和結束。
跟蹤鼠標 （， ） 的上一個位置，并在主應用程序循環(huán)（而不是事件循環(huán)）中繪制線條：lastxlasty
例如：

import pygame
width, height = 800, 600
pygame.init() #As necessary as import, initalizes pygame
gameDisplay = pygame.display.set_mode((width,height)) #Makes window
pygame.display.set_caption('Demo') #Titles window
clock = pygame.time.Clock() #Keeps time for pygame
gameDisplay.fill((0,0,255))
class Draw:
def __init__(self):
self.color = (255, 0, 0)
def update(self, from_x, from_y, to_x, to_y):
pygame.draw.circle(gameDisplay, self.color, (from_x, from_y), 5)
pygame.draw.line(gameDisplay, self.color, (from_x, from_y), (to_x, to_y), 10)
pygame.draw.circle(gameDisplay, self.color, (to_x, to_y), 5)
end = False
down = False
line = Draw()
while not end:
for event in pygame.event.get():
if event.type == pygame.MOUSEBUTTONDOWN:
lastx, lasty = event.pos
down = True
if event.type == pygame.MOUSEBUTTONUP:
down = False
if event.type == pygame.QUIT:
end = True
x, y = pygame.mouse.get_pos()
if down:
line.update(lastx, lasty, x, y)
lastx, lasty = x, y
pygame.display.update()
clock.tick(60)
pygame.quit()
