Pygame跳转动画不起作用-尽管走路可以

问题描述

好的，因此我可以在主文件的左右添加步行动画，但是当我基本上复制/粘贴/更改了要添加跳转的名称时，这是行不通的。

我继续制作了我的主文件的副本，只是没有行走动画。我继续尝试仅做跳跃动画，即使我复制了与步行相同的教程中的所有内容，仍然无法使用。

从昨天晚上8点左右开始，我一直在努力解决这个问题。跳转动画是否有其他工作方式？有关THE copY的代码，请参见下文，因此没有步行动画。我没有错误，玩家可以左右行走，也可以跳跃。

import pygame
import os
x = 90
y = 60
os.environ['SDL_VIDEO_WINDOW_POS'] = "%d,%d" % (x,y)


def player_jump_animation():
    """Adding collision block to each right jump animation"""
    new_player = player_frames_jump[player_jump_index]
    new_player_rect = new_player.get_rect(
        center=(player_rect.centerx,player_rect.centery))
    return new_player,new_player_rect


pygame.init()
screen = pygame.display.set_mode((1000,1000))
clock = pygame.time.Clock()

player_movement = 720
isJump = False
jumpCount = 10

bg_surface = pygame.image.load('assets/camp_bg.png').convert()

pygame.time.set_timer(PLAYERJUMP,120)

run = True
while run:
    keys = pygame.key.get_pressed()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

        if event.type == PLAYERJUMP:
            if player_jump_index < 6:
                player_jump_index += 1
            else:
                player_jump_index = 0

            # Setting jump animation
            player_jump,player_rect = player_jump_animation()

    if keys[pygame.K_LEFT] and player_rect.centerx > 0 + 35:
        # If I speed up,player looks like sliding
        player_rect.centerx -= 5
    if keys[pygame.K_RIGHT] and player_rect.centerx < 1000 - 35:
        # If I speed up,player looks like sliding
        player_rect.centerx += 5

    if not(isJump):
        if keys[pygame.K_UP]:
            isJump = True
    else:
        if jumpCount >= -10:
            neg = 1
            if jumpCount < 0:
                neg = -1
            player_movement -= (jumpCount ** 2) * 0.1 * neg
            jumpCount -= 0.5
        # This will execute when jump is finished
        else:
            # Resetting Variables
            jumpCount = 10
            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()

解决方法

如果玩家在跳跃，则必须绘制player_jump引用的表面：

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)

    # [...]
