Define a pygame.Rect object for the player: player_rect = pygame.Rect(w, y, width, height) or get a rectangle from the player image (player_image): player_rect = player_image.get_Rect(topleft = (x, y)) Get the rectangle of the display Surface (screen) screen_rect = screen.get_rect() Evaluate if the player is out of the screen: if player_rect.left < screen_rect.left or player_rect.right < … Read more
The issue is not the pygame.sprite.Group.add operation, but the obejct you want to add is not a pygame.sprite.Sprite object, because the object is not constructed at all. You missed to the super call in the constructor of Projectile. Furthermore the name of the constructor has to be __init__ rather _init_: class Projectile(pygame.sprite.Sprite): #Initialize values def … Read more
See pygame.transform.flip(): flip(Surface, xbool, ybool) -> Surface This can flip a Surface either vertically, horizontally, or both. pygame.transform.flip() flips creates a new Surface from the source Surface which is flipped. e.g: my_flipped_image = pygame.transform.flip(my_image, True, False);
EDIT: I realized that these steps were originally intended for python3. It should still work for python2, but I can’t confirm, it’s just the best answer I have. Assuming you are using the newest macOS, here are the steps I used to install pygame. Try and uninstall what you installed for pygame previously, I’m not … Read more
When you press UP you don’t have to change the speed, but you have to set the acceleration: self.vel = vec(PLAYER_SPEED, 0).rotate(-self.rot) self.acc += vec(PLAYER_ACC, 0).rotate(-self.rot) Add the acceleration to the velocity: self.vel += self.acc I recommend limiting the maximum. However, I recommend doing this separately for each direction: max_vel = 2 self.vel[0] = max(-max_vel, … Read more
pygame.sprite.LayeredUpdates is a Group object that manages pygame.sprite.Sprite objects. pygame.sprite.LayeredUpdates.move_to_front is a Method Objects. The argument of pygame.sprite.LayeredUpdates.move_to_front must be a pygame.sprite.Sprite objects contained in the Group: Brings the sprite to front, changing sprite layer to topmost layer Therefore you must create a Group layered_group = pygame.sprite.LayeredUpdates() That contains pygame.sprite.Sprite objects. In the following my_sprite … Read more
The white artifacts you can see in the picture are caused because the JPG format is a compressed format. The compression is not lossless. This means the colors around the weapon are not exactly white (255, 255, 255). The color appear to be white for the human eye, but actually the color channels have a … Read more
I recommend to move the scorpion along a list of points (spider_move). Use a variable that states the index of the next point (spider_move_to) and move the scorpion to this point (next_p). Every time when a point is reached, then increment the index (spider_move_to += 1). If no more point is in the list, then … Read more
Create a list of circles Each circle is a tuple with 3 components, the x and y coordinate and the radius. Append new circles as long the length of the list is less than n: circle_list = [] while len(circle_list) < n: # […] Create a random position and radius: r = random.randint(10, 20) x … Read more
You have to align the position to the grids size. Use the floor division operator (//) to divide the coordinates by the size of a cell and compute the integral index in the grid: x, y = pygame.mouse.get_pos() ix = x // sizebtwn iy = y // sizebtwn Multiply the result by the size of … Read more
