python - pygame - 获取文本的当前颜色(pygame.Surface 类型)

Question

我想随机化颜色并每隔几秒更改文本颜色，所以我想确保我不使用相同的颜色。我如何知道当前文本的颜色？

Answer 1

您可以定义 set颜色并使用该集合与当前颜色的差异来获得仅包含不同颜色的集合。然后将其转换为列表并使用 random.choice 选择新颜色。

import random

RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
# Define a set of the colors.
COLORS = {RED, GREEN, BLUE}
color = RED  # Current color.

for _ in range(50):
    # The difference of `COLORS` and the set `{color}` is
    # a set that doesn't contain `color`.
    difference = COLORS - {color}
    # Then you need to convert this set into a list in order
    # to use `random.choice`.
    color = random.choice(list(difference))
    print(color)
