Question

我试图移动一个角色，以便在我移动它时它们面向鼠标;我理解这个概念，但我完全不知道如何编码。目前，我了解如何单独旋转角色以及如何分别移动角色。我可以将两者合并，以便我可以用键和鼠标移动和旋转我的角色吗？

这些是我定义的变量：

xPlayer = 25
yPlayer = 25
dxPlayer = 0
dyPlayer = 0
playerPosition = (25,25)

这是允许图像沿鼠标方向旋转的部分：

go = True
while go:
    position = pygame.mouse.get_pos()


    screen.blit(nightBackground, (0,0))

    mousePosition = pygame.mouse.get_pos()

    angle = math.atan2(mousePosition[1]-(playerPosition[1]+32),mousePosition[0]-(playerPosition[0]+26))

    playerRotate = pygame.transform.rotate(peterPlayer, 360-angle*57.29)

    playerpos1 = (playerPosition[0]-playerRotate.get_rect().width/2, playerPosition[1]-playerRotate.get_rect().height/2)

    screen.blit(playerRotate, playerpos1)

    pygame.display.update()

这是用键控制我的角色的部分：

elif event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            dxPlayer = -15
        elif event.key == pygame.K_RIGHT:
            dxPlayer = 15
        elif event.key == pygame.K_UP:
            dyPlayer = -15
        elif event.key == pygame.K_DOWN:
            dyPlayer = 15

    if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
            dxPlayer = 0
        elif event.key == pygame.K_UP or event.key == pygame.K_DOWN:
            dyPlayer = 0

xPlayer = xPlayer + dxPlayer
yPlayer = yPlayer + dyPlayer
pygame.display.update()

非常感谢任何帮助！
