pygame 事件输入框

Question

我正在开发一款游戏，但我不太了解事件处理的工作原理。我想做到这一点，当玩家输入正确的 6 位数字的第一个数字时，键盘焦点将位于右侧的输入框上，但我对 Pygame 的理解非常有限，我一直挠我的头并寻找了一段时间的解决方案。如果有人能提供帮助，我将不胜感激。

我将 input_box 矩形放入列表中，然后使用 for 循环绘制方框并 blit 数字。您可以只使用一个 text 变量而不是 text1、text2 等，并遍历此变量中的字符以将它们 blit。

内置的zip函数可用于将文本和框压缩在一起，这样您就可以同时获得数字和坐标（或者使用索引）。

input_boxes = [
    pygame.Rect(5,375,140,205),
    pygame.Rect(155,375,140,205),
    pygame.Rect(305,375,140,205),
    pygame.Rect(455,375,140,205),
    pygame.Rect(605,375,140,205),
    pygame.Rect(755,375,140,205),
    ]

在 while 循环中：

# Draw the boxes.
for box in input_boxes:
    pygame.draw.rect(gamedisplay, ran_color1, box)

# Blit one number after the other at the corresponding box.
for number, box in zip(text, input_boxes):
    txt_surface = font.render(number, True, black)
    gamedisplay.blit(txt_surface, (box.x+5, box.y+5))

如果你不熟悉zip函数，你可以使用索引：

for i in range(len(text)):
    txt_surface = font.render(text[i], True, black)
    gamedisplay.blit(txt_surface, (input_boxes[i].x+5, input_boxes[i].y+5))
