Improve this question
So I have been trying to figure out why I keep getting this error, even though everything is run from my game_view.py module. Everytime I press the 1 key to start a game and test to see if the players health bar and hit points works, I get this error message. TypeError: start_new_game() missing 1 required positional argument: 'max_health'
The sad part is, is that it reffers me to the start_view which doesn't have anything to do with anything else but running the start screen so players can choose to play solo or with another player. Below is the game_view and start_view so you guys can see where I'm going wrong. I wanted to test this out so this way I can add other enemies, bosses and power-ups later, but running into this error for the past several days is hindering progress. Anyway, code for both will be below. Thanks in advance for any and all help.

Sorry in advance if I have tons of code to go through. But like I said I am adding some features that wasn't in the Arcade Repository from github. I even set a separte module for the health bar and hit points so this way I can see what conflicts. But the error above has been a royal pain.Thanks again.
P.S. Remarked out joysticks because it was conflicting with another module I built.

As your title says, your start game function requires 2 arguments: player_count and max_healh. And in your code, when using start_new_game, you aren't supplying the max_health argument, thus raising an error.
(function) start_new_game(self, player_count, max_health)

I'm trying to create a simple shooting-platform game, using pygame module. Everything works fine except the jumping. See in line 88. The player is jumping like an x^2 parabola. I added the *0.5 at the end of the line to make the player jump slower and lower, but when I do it this is what happened.
Before jumping:
After jumping:
Look in the second picture. There's a distance between the floor and the player. When I remove the *0.5 everything works fine. Why?

Trying to delete sprite with kill(), but sprite isn't disappearing

This is my first time asking here, so sorry if I don't ask very well.
Lately I've been trying to make a Terraria-type game where you can break/place blocks in a randomly generated landscape. While trying to implement the breaking-block mechanic (which is triggered by clicking on a block), I ran into an issue. The block no longer became solid (that's a good thing), but the block's image is still there, and I can walk right through it.
A visual example:

If someone could explain what I'm doing wrong, it would be much appreciated.
Update 2: Added player class and settings file to help anyone willing to assist me find the issue.

From just a glance, it looks like you might not be clearing the screen at any point in the update loop, but rather drawing over what was already there. This would result in the block still being visible, but not actually there. Try adding screen.fill(#Color here) before flipping the display. Also try using pygame.display.update() instead of pygame.display.flip()

You can do this:
all_sprites = pg.sprite.Group()
all_sprites.add(your_sprite)
#your event:
all_sprites.remove(your_sprite)

Scrolling camera

I've been tinkering with a scrolling camera that follows the player around and have got it to follow the player. The problem is that it moves slower than the player and because of this the player wont stay in the middle of the screen.
I believe the problem is in the offset (cameraX) and have tried a few different values but haven't found any that work.

pygame.display.update()
mainClock.tick(FPS)

You don't apply the camera-offset to the player itself, only to the wallblocks.
So change
pygame.draw.rect(screen, (0, 0, 0), player)
to
pygame.draw.rect(screen, (0, 0, 0), player.move(-cameraX, 0))
Some more notes:
Using three lists (blockList, blockListDisp, blockTypeList) to keep track of your level is way to complex, use a single list :-)
Change your add_level to:
# use a dict to keep track of possible level blocks, so adding new ones becomes simple
types = {0: "air", 1: "solid"}
def add_level(lvl, bSize): # Creates the level based on a map (lvl) and the size of blocks
for y in range(len(lvl)):
for x in range(len(lvl[0])):
# no more if/elif
yield types[lvl[y][x]], pygame.Rect((bSize * x), (bSize * y), bSize, bSize)
your lists to:
blocks = list(add_level(currLevel, BLOCKSIZE)) # a single list which holds the type and rect for each block of the level
Then your collision detection can look like this:
while True:
"""COLLISION"""
collision = False
for type, rect in blocks: # list contains a tuple of type, rect
if type == "solid":
if player.colliderect(rect):
collision = True
if vx > 0 and not falling:
player.right = rect.left # now you can always use the rect directly instead of accesing other lists
vx = 0
print('Collide Right')
...
Also, the drawing code becomes simpler:
for type, rect in blocks:
if type == "solid":
screen.blit(wallblock, rect.move(-cameraX, 0)) #blit the wall-block graphics
pygame.draw.rect(screen, (0, 0, 0), player.move(-cameraX, 0))
In the long run, you may want to use a class instead of a tuple, but that's another topic.

Trouble using the same image for multiple objects

I'm making a game with Pygame and I'm trying to animate asteroids that get hit with a bullet. The animation works fine if there's just one asteroid type on the screen. I run into trouble when there's two identical asteroids on the screen. It seems that the first one on is the only one that uses my animation.
For example, say the game spawns two small asteroids, these are the exact same and I'm using glob.glob to get the 4 animation images, then I'll just use those images to create a little animation by looping over them. This works with one of the asteroids, the other will not play the animation. I'm thinking it must be because only one object can use specific images at any one time?
I'm sorry for the terrible explaination.
Here's the asteroid class I have and the call to create the animation:
class Asteroid(pygame.sprite.Sprite):
def __init__(self, screen, size):
pygame.sprite.Sprite.__init__(self)

Although I can't be sure because the bit where you call update is not shown, I have a few ideas of why it is doing what it is. It seems that the second asteroid's update is not being called. This could be for several reasons. The first reason is if you do not implement groups to update you asteroid. Basically, if you only call your single instance of the asteroid, the second one will not do anything, even show up on the screen. If this is the case, you will need to make a group, perhaps a render updates group but even a list would be fine. This would mean you could do something like:
asteroids.update()
or
for asteroid in asteroids:
asteroid.update()
the above two codes assume that you have some kind of grouping of asteroids, called asteroids.
Another possible problem, if you are implementing groups, is if the second asteroid is not getting added to this group. If you tell it to add itself to the group in the init function, this problem will not be there, however, if you call it outside of this function, you may not be doing so when you make your second asteroid. To address this problem just move the part where you add the asteroid into a group that will be updated to the init function of asteroids.
