所以基本上这个程序几乎可以正常工作,它应该显示同心圆的模拟,唯一的大问题是我不知道如何在中心显示圆圈,因为中间只有一个空的空间

我已经尝试使用与其他圆圈相同的概念,并且只更改了范围,使其保持在中间,但它没有达到我想要的效果。所以我只是让程序在中间显示一个圆圈,它的半径应该适合所有频率

我正在寻找一种在中间显示圆圈的算法,或者其他可能的解决方案

最佳答案

圆的最小半径是int(pace * radiusMax)

用这个半径画一个“中心”圆:

例如

centerradius1 = int(pace * radiusMax)    
pygame.draw.circle(screen, black, circle1spot, centerradius1, 1)

如果您将动画的中心点、频率和颜色等参数传递给一个函数 circle,那么您将能够对所有动画使用一个函数 circle:

def circle(radius, center, freq, color):
radius = radius + 1
num_circles = math.ceil(radius / freq)
radiusMax = num_circles * freq
pace = freq / radiusMax

centerradius = int(pace * radiusMax)
pygame.draw.circle(screen, color, center, centerradius, 1 )

for y in range(num_circles, 1, -1):
radiusY = int(((pace * (num_circles - y)) + pace) * radiusMax) + (radius % freq)
pygame.draw.circle(screen, color, center, radiusY, 1)
return radius

像这样调用函数 circle:

while keep_going:

# [...]

radius = circle(radius, circle1spot, freq, black)

if twocircles == True or threecircles == True:
radius2 = circle(radius2, circle2spot, freq2, red)

if threecircles == True:
radius3 = circle(radius3, circle3spot, freq3, green)
