Pygame 跳跃动画不工作 - 虽然步行是

Question

好的，所以我能够在我的主文件中向右和向左添加行走动画，但是当我基本上 copy/pasted/changed 添加跳跃的名称时，它不起作用。

我继续制作了我的主文件的副本，只是没有行走动画。我继续尝试只做跳跃动画，即使我复制了我用于行走的同一教程中的所有内容，它仍然不起作用。

从昨晚大约晚上 8 点开始，我一直在努力解决这个问题。跳跃动画有不同的工作方式吗？请参阅下面的 THE COPY 代码，因此没有行走动画。我没有出错，玩家可以左右行走，也可以跳跃。

import pygame

x = 90
y = 60

        center=(player_rect.centerx, player_rect.centery))
    return new_player, new_player_rect

        # This will execute when jump is finished
        else:

            isJump = False

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

    screen.blit(bg_surface, (0, 0))
    player_rect.centery = player_movement
    screen.blit(player_idle, player_rect)


pygame.quit()

Answer 1

你必须绘制 player_jump 引用的 Surface，如果玩家在跳跃：

while run:
    # [...]

    screen.blit(bg_surface, (0, 0))
    player_rect.centery = player_movement
    if isJump:
        screen.blit(player_jump, player_rect)
    else:
        screen.blit(player_idle, player_rect)

    # [...]
