So this is my game I've bean working on and so have things are going very well, the player can move around and shoot down the boxes which are ment to be moving but theres these small glitches, but before I go on heres the code:

So glitch number one:
only one of the boxers moves, I cant figure out why it only one of them is moving towards the player, all the boxers are meant to move towards the player as this is hoping to become a zombie shooter.
Glitch two:
At a random point the box that does move does stops moving in all directions but one, so lets say this happens when the box in in the center of the screen, if the player goes to the left of the box, nothing, but when the player moves to thr right of the player it moves right, but only right not up or down, and this seams to happen at soem point everytime.
Well thats it, hope you can help thanks heaps stackoverflow

Changes:
player can move but can leave screen
press space to pause game - but you can still move cursor and fire :)
bullet has max range - than it is removed
i change bullet vetor calculations because value was rounded to integer every frame and bullet trajectory was incorrect
bullet never change trajectory when player is moving
all code is in classes except some constant values. I add class Crosshair and Background
you can see how class (Player) handle events in event_handle
I use pygame.Rect() (screen.get_rect(), image.get_rect()) to get rect.top, rect.left, rect.center, rect.centerx, rect.topleft, etc.
There is still many things to do.
ps. if someone needs images 'ball1.png', 'ball2.png', 'ball3.png' to run this example you can find it in answer to

The instruction self.rect.x(-5, 0) doesn't make any sense. You can move a sorite respectively rectangle with the pygame.Rect.move_ip instruction:
self.rect.x(-5, 0)
self.rect.move_ip(-5, 0)
Change the clouds position to the right as it goes out of the Window:
class Clouds(pygame.sprite.Sprite):
# [...]
def update(self):
self.rect.move_ip(-5, 0)
if self.rect.right <= 0:
self.rect.left = screen.get_width()
When I shoot at my cement block sprites I have it set so that self.score is self.score += 1 in my player collision function, but when I shoot my cement blocks and destroy them, either 1 or 2 points is added at random to my score. Why? How can I fix this? A clear example is, I shoot at and destroy 2 cement blocks in a row and 1 point is added for each one destroyed which means my score is 2, which is what I want cause I want to add 1 point to my score whenever I destroy a cement block, but then when I shoot and destroy the third cement block, 2 points are added instead of 1 bringing my score to 4 instead of being a score of 3 points.

So I was making a pygame platformer and I got stuck on one thing. I coudn't find a way to make the bottom of my platforms solid. The player could land on the top of it but when it tries to go through the bottom it bounces back down. I tried this but it didnt work:
hits = pg.sprite.spritecollide(player, platforms, False)
if hits:
if player.pos.y == hits[0].rect.top:
player.vel.y = 10
else:
player.pos.y = hits[0].rect.top + 1
player.vel.y = 0
Does anyone got a solution for me? Here's the complete program.
Here's a short platformer example. Especially the movement is important. You have to move along the x-axis first, check if the player collides with a wall and move it back if a collision occurred. Afterwards do the same with the y-axis. If you don't split the movement into these two parts, your player will jump to the sides, top or bottom of the wall if you press more than one movement key at the same time.

Here's a working version of the code that you've posted in the comments (only with vertical collisions, you need to add horizontal collisions as well). So when the player is jumping and collides with a platform, you have to set the player.rect.top to the platform.rect.bottom and change the vel.y.

BTW, in the jump method you have to change self.rect.y not self.rect.x.
I am working on a game in pygame, so far the player can walk around, 50 blue blocks spawn randomly on the screen and the player can walk around and shoot them, but there is one problem the player can only shoot up, I want the player to shoot towards the mouse but am having some trouble getting it to do this.
this is my code

so there the code, any help is much appreciated
here is what i came up with, I changed some code from an RPG me and a friend are making
Change your bullet class code to this:
class Bullet(pygame.sprite.Sprite):
def __init__(self, mouse, player):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.Surface([4, 10])
self.image.fill(black)
self.mouse_x, self.mouse_y = mouse[0], mouse[1]
self.player = player
self.rect = self.image.get_rect()
def update(self):
speed = 4.
range = 200
distance = [self.mouse_x - self.player[0], self.mouse_y - self.player[1]]
norm = math.sqrt(distance[0] ** 2 + distance[1] ** 2)
direction = [distance[0] / norm, distance[1 ] / norm]
bullet_vector = [direction[0] * speed, direction[1] * speed]
self.rect.x -= bullet_vector[0]
self.rect.y -= bullet_vector[1]
now it takes the players pos and the mouse click pos as arguments for the class
the math is a bit confusing but it basically take the vector from the two points and gets a direction and sends the bullet that way
when you create a new bullet instance call it like this:
bullet = Bullet(pygame.mouse.get_pos(), [player.rect.x, player.rect.y])
that way the class gets the two points when the mouse button is clicked!
when you run it you may notice that the bullet goes in the opposite direction of the mouse click thought that would add some challenge. You can change it if you need
P.S. the speed variable can be adjusted! Oh, and the math module needs to be imported
I have created code to see whether my aliens are dead however it doesn't work, can anyone see the problem.
