I am still adding stuff to this game to complete it. Now I added some fx, among other stuff.
Fx
These 2 methods of the class Win are responsible of the fx
- explosion_fx (called when the event of winning happens)
- particles_explosion (called every frame, but visible only when it’s triggered (filling the particles list with data for generating them) until the particles are removed (when they are too small)
So, you win, there’s a call to explosion_fx to create 10 particles filling the self.particles list. These list makes the particles appear and transform by the particle_explosion method that is called every frame. When the particles became small the are removed and so the effect is not visible untile next won.
def explosion_fx(self, r1, c1, r2, c2):
for i in range(10):
# self.particles2.append(
# [
# [pygame.mouse.get_pos()[0],pygame.mouse.get_pos()[1]],
# [random.randint(0, 42) / 6 - 3.5, random.randint(0, 42) / 6 - 3.5],
# random.randint(4, 6)])
self.particles2.append(
[
[c1*tile_size + 50, r1*tile_size + 50],
[random.randint(0, 42) / 6 - 3.5, random.randint(0, 42) / 6 - 3.5],
random.randint(4, 6)])
self.particles2.append(
[
[c2*tile_size + 50, r2*tile_size + 50],
[random.randint(0, 42) / 6 - 3.5, random.randint(0, 42) / 6 - 3.5],
random.randint(4, 6)])
def particles_explosion(self, pcolor):
''' call this in a for i in range(10) '''
scale_x = 0
for particle in self.particles2:
particle[0][0] += particle[1][0]
loc_str = str(int(particle[0][0] / tile_size)) + ';' + str(int(particle[0][1] / tile_size))
# if loc_str in tile_map:
# particle[1][0] = -0.7 * particle[1][0]
# particle[1][1] *= 0.95
# particle[0][0] += particle[1][0] * 2
particle[0][1] += particle[1][1]
loc_str = str(int(particle[0][0] / tile_size)) + ';' + str(int(particle[0][1] / tile_size))

# particle[1][0] *= 0.95
# particle[0][1] += particle[1][1] * 2
particle[2] -= 0.035
particle[1][1] += 0.15
# self.surf.set_colorkey(pcolor)
# ======================================= EXPLOSION ================================
scaling = (100-int(particle[1][1]*10))
if scaling > 0:
scale_x = scaling
self.screen.blit(
pygame.transform.scale(surf_star, (scale_x, scale_x)),
(particle[0][0]+25, particle[0][1]+25))
self.screen.blit(
pygame.transform.scale(self.surf, (scale_x, scale_x)),
(particle[0][0], particle[0][1]))
self.screen.blit(
pygame.transform.scale(message("+10"),
(scale_x, scale_x)),
(particle[0][0], particle[0][1]))
pygame.draw.circle(self.screen, pcolor, [int(particle[0][0]), int(particle[0][1])], int(particle[2]))
if particle[2] <= 0:
self.particles2.remove(particle)
# ====================================== End showing particles when win =============
Here it’s the trigger
To make the animation of the particles, you call, instead, self.particles_explosion(self.color) that takes care of moving the particles, making them smaller and deleting them at the end.
if self.matches > 0:
self.particles_explosion(self.pcolor)
