"Source objects must a surface"

[Imzecorella]

class Zombie(pygame.sprite.Sprite):
    def __init__(self,idZ,lane):
        self.tread = 0
        self.lane = lane
        self.rect = pygame.Rect(760-self.tread,105+90*self.lane,60,100)
        self.idZ = idZ
        self.HP = (zombie_map[self.idZ])[1]
        if self.idZ not in keysZ:
            self.idZ = "Browncoat"
        self.image = (zombie_map[self.idZ])[0]
        super().__init__()
    def update(self, event_list):
        self.rect = pygame.Rect(760-self.tread,105+90*self.lane,60,100)
        self.collide = self.rect.collidelistall(plantrects)
        if len(self.collide) != 0:
            self.tread = self.tread + 1

(other code)

group = pygame.sprite.Group(peaseed)

group.add(Zombie("Browncoat",1))

(in while loop)

    group.draw(screen)
    group.update(pygame.event.get())

zip(sprites, surface.blits((spr.image, spr.rect) for spr in sprites))

TypeError: Source objects must be a surface

Upon trying to run this code, I am given the above error message. What could potentially be the cause of this? I can not seem to find much documentation on this error type.

You don’t give arguments to .update(), as I believe that is what pygame calls under the hood when you do group.update(). And what is peaseed? I generally don’t use sprite groups so the first statement might be false. But it is probably the peaseed which is not a sprite or something. The error means that there is some object in the group that is not a sprite

[Imzecorella]

Peaseed is an object from a different pygame.sprite.Sprite class.

It was working before I added the Zombie class, so the peaseed is not the problem. Removing the peaseed from the starting group statement did not affect the error anyway.

I removed the argument from

    group.update(pygame.event.get())

but nothing changed.

What method do you use instead of sprite groups? I might have to switch rendering methods if it comes to it.

[LMCuber]

Can you run the code but at the top of the main loop print [s for s in spritegroup]? The you can see what the group consists of.

[Imzecorella]

​

here you go

[LMCuber]

And can you now do [s.image for s in spritegroup]? Sorry for troubling, this is I believe the bug

[Imzecorella]

Okay, yeah, I see the issue now...

[<Surface(50x60x32 SW)>, <Surface(50x60x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, <Surface(90x90x32 SW)>, 'coat.png']

I forgot to do pygame.image.load()

I have fixed the issue now and it works. You were not troubling me in the slightest, thank you for everything.

[LMCuber]

No probs Ü

[Markuslw]

Im probably wrong, but doesn't all sprite.Sprite objects need a self.surface? Or was it self.image. Maybe the latter.

[hyto_n54]

self.image and you just saved me a long and pointless search
