【问题描述】：
我制作了一个程序，其中一个对象将在屏幕上朝着您的鼠标旋转。现在我需要让它向另一个移动的物体旋转。这是我的代码：
import pygame
import math
import sys
from pygame.locals import *;
from sys import exit
pygame.init()
blk = pygame.Color(0,0,0)
BG = ('BG.png')
pygame.init()
screen = pygame.display.set_mode((800, 600))
B_G = pygame.image.load(BG).convert_alpha()
clock = pygame.time.Clock()
pygame.mouse.set_visible(False)
fpsclock = pygame.time.Clock()
class Shork(pygame.sprite.Sprite):
def __init__(self):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.image.load('SHORK.png')
screen = pygame.display.get_surface()
self.x = 62
self.y = 50
self.direction = "down"
def Moving(self):
if self.direction == "right":
self.x += 2
elif self.direction == "left":
self.x -= 2
elif self.direction == "down":
self.y += 2
elif self.direction == "up":
self.y -= 2
def Path(self):
if self.x == 62 and self.y == 538:
self.direction = "right"
if self.x == 246 and self.y == 538:
self.direction = "up"
if self.x == 246 and self.y == 366:
self.direction = "left"
if self.x == 176 and self.y == 366:
self.direction = "up"
if self.x == 176 and self.y == 114:
self.direction = "right"
if self.x == 530 and self.y == 114:
self.direction = "down"
if self.x == 530 and self.y == 366:
self.direction = "left"
if self.x == 460 and self.y == 366:
self.direction = "down"
if self.x == 460 and self.y == 538:
self.direction = "right"
if self.x == 644 and self.y == 538:
self.direction = "up"
if self.y == 0:
sys.exit()
Shork = Shork()
Run = True
while True:
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
elif event.type == MOUSEBUTTONDOWN and event.button == 1:
print("test1")
elif event.type == MOUSEBUTTONDOWN and event.button == 3:
print("test3")
while Run:
fpsclock.tick(60)
for event in pygame.event.get():
if event.type == pygame.QUIT:
Run = False
pos = pygame.mouse.get_pos()
angle = 360-math.atan2(pos[1]-300,pos[0]-400)*180/math.pi
rotimage = pygame.transform.rotate(B_G,angle)
Shork.Moving()
Shork.Path()
screen.blit(Shork.image, (Shork.x, Shork.y))
pygame.display.update()
rect = rotimage.get_rect(center=(400,300))
screen.blit(rotimage,rect)
pygame.display.update()
screen.fill(blk)
BG 是我需要旋转的对象， SHORK 是 BG 需要旋转的对象。 代码的中间部分只是跟踪一个对象的路径。 我正在努力的代码是这样的：
pos = pygame.mouse.get_pos()
angle = 360-math.atan2(pos[1]-300,pos[0]-400)*180/math.pi
rotimage = pygame.transform.rotate(B_G,angle)
Shork.Moving()
Shork.Path()
screen.blit(Shork.image, (Shork.x, Shork.y))
pygame.display.update()
rect = rotimage.get_rect(center=(400,300))
screen.blit(rotimage,rect)
pygame.display.update()
这目前适用于跟随鼠标，但我一生无法弄清楚如何使 BG 向 SHORK 旋转。 附言我刚开始学习python，所以请耐心等待。 :)
