在pygame上开发游戏时出现错误

Question

我只是有一个很长一段时间无法解决的问题。一般来说：我想为我的游戏制作一个播放器动画。我已经下载了一些精灵：1：5个精灵用于左手动画2：5个用于右手动画的精灵3：玩家静止不动时1个精灵我的代码中有一个错误：当玩家左右移动时，会显示该玩家静止不动的图片。当玩家跳跃并向右/向左移动时，一切正常这是指向github仓库的链接：github.com/Fierce-Wolf/Game代码：

pygame.init()

Answer 1

[Left = False和Right = False设置在错误的位置：

• 全部设置为False，然后评估移动方向。
• 根据移动方向进行更改
• 如果玩家跳跃则重置

while my_game:

    Left, Right = False, False # <------------ 

    # Move left
    if (keys[pygame.K_LEFT] or keys[pygame.K_a]) and x > 5:
        x -= speed
        Left = True # <------------ 
    # Move right
    if (keys[pygame.K_RIGHT] or keys[pygame.K_d]) and x < (500 - width - 5):
        x += speed
        Right = True # <------------ 

    if not(isJump): # If player didn't jump
        # jump
        if keys[pygame.K_SPACE]:
            isJump = True
        # if player doesn't move
        else:
            animCount = 0

    # If player jump
    else:
        # Create the physics of jump
        if jumpCount >= -10:
            Left, Right = False, False # <------------ 

            # ↓ This operator is necessary for the player to go down
            # after climbing up
            if jumpCount < 0:
                y += (jumpCount ** 2) / 2
            else:
                # Raising the player up
                y -= (jumpCount ** 2) / 2

            # Уменьшаем еденицу прыжка
            jumpCount -= 1

            # This way the player will go up and down 
            # the same number of units
            # => вверх = вниз

        # Jump 'over'
        else:
            # Returning the isjump variable to its original value,
            isJump = False

            # Returning the old value to the jumpcount variable
            jumpCount = 10
