pygame - 文本框呈现在pygame的主代码之上？

问题描述

我已经在我的模拟中实现了文本框代码，但现在它没有渲染主代码，或者在我的主代码之上渲染，所以除了框之外什么都没有显示:(

这是我的文本框代码：

def textbox(font20):
    input_box = pygame.Rect(300,225,400,100)
    color_inactive =(TURQUOISE)
    color_active = (0,255,249)
    color = color_inactive
    active = False
    text = ""
    done = False
    font = font20
    while not done:
        for event in pygame.event.get():
            
            if event.type == pygame.MOUSEBUTTONDOWN:
                if input_box.collidepoint(event.pos):
                    active = not active
                else:
                    active = False
                color = color_active if active else color_inactive
            if event.type == pygame.KEYDOWN:
                if active:
                    if event.key == pygame.K_RETURN:
                        print(text)
                        text = ""
                        done = True
                    elif event.key == pygame.K_BACKSPACE:
                        text = text[:-1]
                    else:
                        text += event.unicode
                # Render the current text.
        text_surface = font.render(text, True, color)
        # Resize the box if the text is too long.
        width = max(200, text_surface.get_width()+10)
        input_box.w = width
        # Blit the text.
        screen.blit(text_surface, (input_box.x+5, input_box.y+5))
        # Blit the input_box rect.
        pygame.draw.rect(screen, color, input_box, 2)

        pygame.display.flip()

我还在screen.blit我绘制屏幕并翻转它的底部添加了绿松石色。

解决方案

你记得点击框吗？;)

还有一堆小问题：

  • 该代码没有TURQUOISE.
  • 循环没有处理该pygame.QUIT事件。
    • 它还需要将此事件传播到外循环
  • 随着盒子的增长，它变得一团糟，我添加了一个黑色矩形来擦除旧的。
  • 它没有返回text值。

修复了所有这些非常轻微的错误，它工作得很好。但是请记住先单击该框！

                    print( "DEBUG: text is now [%s]" % ( text ) )
                # Render the current text.
        text_surface = font.render(text, True, color)

        input_box.w = width
        # Blit the input_box rect.
        pygame.draw.rect(screen, color_background, input_box) # filled box to clear the old one
        pygame.draw.rect(screen, color, input_box, 2)
        # Blit the text.
        screen.blit(text_surface, (input_box.x+5, input_box.y+5))

        pygame.display.flip()

    return text


font = pygame.font.SysFont('', 24)
textbox( font )

pygame.quit()
