首先,您必须move在主应用程序循环中调用:
def main():
pygame.init()
display = pygame.display.set_mode((screenWidth, screenHeight))
clock = pygame.time.Clock()
heroOne = Hero([150, 450])
running = True
while running:
clock.tick(300)
display.fill((255, 255, 255))
heroOne.move()
heroOne.draw(display)
pygame.display.update()
您必须在每一帧中通过self.dirX和更改播放器的位置:self.dirY
class Hero:
# [...]
def move(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_RIGHT:
self.dirX = 1
elif event.key == pygame.K_LEFT:
self.dirX = -1
new_x = self.pos[0] + self.dirX
new_y = self.pos[1] + self.dirY
self.pos = [new_x , new_y]
def draw(self, display):
pygame.draw.rect(display, self.color, (*self.pos, self.width, self.height))
如果你想移动矩形,就在按下一个键的时候,那么我建议使用pygame.key.get_pressed而不是KEYDOWN事件:
class Hero:
# [...]
def move(self):
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
self.pos[0] -= 1
if keys[pygame.K_RIGHT]:
self.pos[0] += 1
if keys[pygame.K_UP]:
self.pos[1] -= 1
if keys[pygame.K_DOWN]:
self.pos[1] += 1
完整代码:
import pygame
import random
import math
import sys
screenWidth = 1200
screenHeight = 600
class Hero:
def __init__(self, pos):
self.pos = pos
self.width = 30
self.height = 30
self.color = (0, 0, 0)
self.dirX = 0
self.dirY = 0
def move(self, events):
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
self.pos[0] -= 1
if keys[pygame.K_RIGHT]:
self.pos[0] += 1
if keys[pygame.K_UP]:
self.pos[1] -= 1
if keys[pygame.K_DOWN]:
self.pos[1] += 1
def draw(self, display):
pygame.draw.rect(display, self.color, (*self.pos, self.width, self.height))
def jump(self):
pass
def die(self):
pass
class Enemy:
pass
class Background:
pass
class Obstacles:
pass
class Camera:
pass
def score():
pass
def main():
pygame.init()
display = pygame.display.set_mode((screenWidth, screenHeight))
clock = pygame.time.Clock()
heroOne = Hero([150, 450])
running = True
while running:
clock.tick(300)
events = pygame.event.get()
for event in events:
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
heroOne.move(events)
display.fill((255, 255, 255))
heroOne.draw(display)
pygame.display.update()
main()

在您的create函数中,您正在创建Hero每次调用时的新实例。
相反,在 中初始化 heroOne main,并将其作为参数传递,以便您可以使用它:
def main():
pygame.init()
heroOne = Hero([150, 450])
clock = pygame.time.Clock()
running = True
while running:
clock.tick(30)
create(screenWidth, screenHeight, heroOne)
还要在move方法中添加增量:
self.dirX += 1
和:
self.dirX -= 1
现在对象将by one在每次按键时移动。
如果你想要连续移动,你应该放一些flag,例如,如果它是True +=1和“False” -=1,按键将改变flag状态。
