Pygame - particle effects
I am making a 2D game using Pygame.
I want to add particle effects to a game I am working on. I want to do things like smoke from smoke, fire, blood, etc. I'm curious if there is an easy way to do this? I don't even know where to start. I just need a basic one that I could expand on.
Pls help.

You might just want to create a class made up of rectangles that go up and randomly move to the right or left each time it is updated for smoke. Then make a ton of them whenever you want. I will try to make the example code below, but I cannot guarantee that it will work. You can create similar classes for other particle effects.
class classsmoke(pygame.Rect):
'classsmoke(location)'
def __init__(self, location):
self.width=1
self.height=1
self.center=location
def update(self):
self.centery-=3#You might want to increase or decrease this
self.centerx+=random.randint(-2, 2)#You might want to raise or lower this as well
#use this to create smoke
smoke=[]
for i in range(20):
smoke.append(classsmoke(insert location here))
#put this somewhere within your game loop
for i in smoke:
i.update()
if i.centery<0:
smoke.remove(i)
else:
pygame.draw.rect(screen, GREY, i)
Another option is to make the class just a tuple, for example:
class classsmoke():
'classsmoke(location)'
def __init__(self, location):
self.center=location
def update(self):
self.center[1]-=3
self.center[0]+=random.randint(-2, 2)
#to create smoke
smoke=[]
for i in range(20):
smoke.append(classsmoke(insert location here))
#put inside game loop
for i in smoke:
i.update()
if i.centery<0:
smoke.remove(i)
else:
pygame.draw.rect(screen, GREY, (i.center[0], i.center[1], 1, 1))
Or, to avoid classes entirely:
#to create smoke:
smoke=[]
for i in range(20):
smoke.append(insert location here)
#put within your game loop
for i in smoke:
i[1]-=3
i[0]+=random.randint(-2, 2)
if i[1]<0:
smoke.remove(i)
else:
pygame.draw.rect(screen, GREY, (i[0], i[1], 1, 1))
Pick your preference and do something similar for other particle effects.
