How to show shields level by changing color of the progress bar

问题

I have a progress bar in the code which only shows a GREEN color but i want to modify it with the percentage of a player, if player is between 50 to 100% then its color is GREEN, if it is less than 50 and equal to 25 its color is ORANGE and under 25% is RED color. I have attached a python code

I would be very thankful if anybody help

def draw_shield_bar(surf, x, y, pct):

def draw_shield_bar(surf, x, y, pct):
    if pct < 0:
       pct = 0
    BAR_LENGTH = 100
    BAR_HEIGHT = 10
    fill = (pct / 100) * BAR_LENGTH
    outline_rect = pygame.Rect(x, y, BAR_LENGTH, BAR_HEIGHT)
    fill_rect = pygame.Rect(x, y, fill, BAR_HEIGHT)
    pygame.draw.rect(surf, GREEN, fill_rect)
    pygame.draw.rect(surf, WHITE, outline_rect, 2)

回答1:

Just set the color dependent on the percentage:

color = GREEN if pct >= 50 else ORANGE if pct >= 25 else RED
pygame.draw.rect(surf, color, fill_rect)

By the way, the parameters to pygame.Rect() have to be integral, so when you calculate fill, then you've to use the integral division operator (//), rathet then the floating point division (/):

fill = BAR_LENGTH * pct // 100
