武器绕圈移动而不是旋转 pygame

Question

武器应该像这个视频中那样围绕玩家旋转 https://www.youtube.com/watch?v=xgkPuKbVXl0 但它不会旋转，它只是在一个圆圈内移动，这是我的代码

这就是武器class

#weapon class
import pygame
import math

from pygame import rect
from pygame import image
texture = pygame.image.load("Textures/frames/weapon_knight_sword.png")


class Weapon(pygame.sprite.Sprite):
    def __init__(self, texture=texture, scale=(12, 20), range=10):
        super().__init__()
        self.image = texture
        self.CurrentImage = texture
        self.angle = 0
        self.x = 0
        self.y = 0
        self.rect = self.CurrentImage.get_rect(center=(0, 0))
        self.listOfActions = [self.getRotationAngle, self.rotate]

    def getRotationAngle(self):
        mouse_x, mouse_y = pygame.mouse.get_pos()
        rel_x, rel_y = mouse_x - self.x, mouse_y - self.y
        self.angle = (180 / math.pi) * -math.atan2(rel_y, rel_x)

    def rotate(self):
        print(self.angle)
        image = pygame.transform.rotate(self.image, -self.angle)
        self.rect = image.get_rect(center=(self.x, self.y))

    def applyActions(self):
        for i in range(len(self.listOfActions)):
            self.listOfActions[i]()

玩家将武器对象作为属性，并在每次更新时为其提供凭据玩家继承自 GenericEntity class，它与游戏中的其他生物有一些共同的属性和方法

问题似乎是您没有存储武器的旋转图像，只存储了它占据的矩形：

def rotate(self):
    print(self.angle)
    image = pygame.transform.rotate(self.image, -self.angle)
    self.rect = image.get_rect(center=(self.x, self.y))

您需要在旋转方法中将图像设置为旋转后的图像，只需确保添加一个新字段来存储原始未旋转的图像以供将来旋转：

def rotate(self):
    print(self.angle)
    self.image = pygame.transform.rotate(self.orig_image, -self.angle)
    self.rect = self.image.get_rect(center=(self.x, self.y))

武器绕圈移动而不是旋转 pygame

Weapon moves in a circle rather than rotate in pygame
