[split] Accurate Clicks Per Second

[SheeppOSU]

That effect is more that just a circle, there is a drawing effect applied when it is blit, and or the images are translucent. The color stacks up with overlapping circles, and they fade as they expand.

ripple_list = []

class Ripple:
    def __init__(self, pos):
        self.pos = pos
        self.radius = 0
        self.max_radius = 50
        self.surf = pygame.Surface((self.max_radius*2, self.max_radius*2)
        self.rect = self.surf.get_rect()
        self.surf.fill((0,0,0))
        self.surface.set_colorkey((0,0,0))
        self.alpha = 255
        self.surf.set_alpha(self.alpha)
        self.color = (0, 0, 255)
        self.fade = 2
        self.growth_speed = 2
        self.rect.center = self.pos
    def update(self):
        if self.radius < self.max_radius:
            self.surf.fill((0,0,0))
            pg.draw.circle(self.surf, self.color, (self.max_radius, self.max_radius), self.radius) 
            self.alpha -= self.fade
            self.radius += self.growth_rate
        else:
            ripple_list.remove(self)   
   

When you click, spawn a ripple with ripple_list.append(Ripple(Your_mouse_pos)). And each frame:

for r in ripple_list:
    r.update()
for r in ripple_list:
    your_game_window.blit(r.image, r.rect)

That will get you started.

instead of using ripple_list as a global variable I think something like this would be better:

    def update(self):
        if self.radius < self.max_radius:
            self.surf.fill((0,0,0))
            pg.draw.circle(self.surf, self.color, (self.max_radius, self.max_radius), self.radius) 
            self.alpha -= self.fade
            self.radius += self.growth_rate
            return False
        else:
            return True

for r in ripple_list:
    if r.update():
        ripple_list.remove(r)
for r in ripple_list:
    your_game_window.blit(r.image, r.rect)
