如何实现矢量运动？

如何解决如何实现矢量运动？

我一直在尝试对此实施运动，但我不知道该怎么做。如果你们中有人知道怎么做，那将是一个很大的帮助！

顺便说一句，这是代码：

import pygame 
from pygame.math import Vector2


class Player(pygame.sprite.Sprite):

    def __init__(self,pos):
        super().__init__()
        self.image = pygame.Surface((50,30),pygame.SRCALPHA)
        pygame.draw.polygon(self.image,pygame.Color('steelblue2'),[(0,0),(50,15),(0,30)])
        self.orig_image = self.image  # Store a reference to the original.
        self.rect = self.image.get_rect(center=pos)
        self.pos = Vector2(pos)

    def update(self):
        self.rotate()

    def rotate(self):
        direction = pygame.mouse.get_pos() - self.pos                   #positionen av musen
        radius,angle = direction.as_polar()                            #as_polar ger koordinaterna av vectorn från polarna
        self.image = pygame.transform.rotate(self.orig_image,-angle)   #roterar bilden vid den negativa axeln
        self.rect = self.image.get_rect(center=self.rect.center)        #Skapa en ny rect i centern av den gamla

#setup
pygame.init()
clock = pygame.time.Clock()

#Game screen
screen_width = 800  
screen_height = 800
screen = pygame.display.set_mode((screen_width,screen_height))


all_sprites = pygame.sprite.Group(Player((300,220)))


# Game Loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

    all_sprites.update()
    screen.fill((30,30,30)) #bakgrundsfärg på spelet
    all_sprites.draw(screen)

    pygame.display.flip()
    clock.tick(60)
