camera

Implementation of the game's camera

Camera Objects

class Camera()

Class to draw different camera angles

__init__

 | __init__(cx, cy, mode='default')

Initializes the game camera

The game camera has 3 modes:

• default: Follows the ball while showing surrounding players
• zoomed: Follows the ball closely
• full: Displays the entire field

Attributes:

• cx float - Camera's x coordinate
• cy float - Camera's y coordinate
• mode str - The camera mode

params

 | @property
 | params()

Helper method to reduce code redundancy

set_mode

 | set_mode(mode)

Set the camera's mode. Mode must be one of ['full', 'default', 'zoomed']

move

 | move(bx, by, alpha=P(0.9,0.9))

Move the camera to the given coordinates (Camera can't go over the field boundary)

Uses exponential smoothing to minimize jittering

pt

 | pt(p)

Transform any 2-D point with respect to the camera

rect_in_view

 | rect_in_view(r1)

Check if given rectangle is within the camera's view

circle_in_view

 | circle_in_view(x, y, rad)

Check if given circle is within the camera's view

rect

 | rect(win, col, coords, width=0)

Draw a rectangle according to the cameras mode (attributes are same as pygame.draw.rect)

circle

 | circle(win, col, p, r, width=0)

Draw a circle according to the cameras mode (attributes are same as pygame.draw.cirlce)

polygon

 | polygon(win, col, pts)

Draw a polygon according to the cameras mode (attributes are same as pygame.draw.polygon)

blit

 | blit(win, path, pt, size)

Blit a given sprite to the surface according to the cameras mode

Attributes:

• win pygame.Window - window for drawing
• path pygame.Image - path to the sprite
• pt P - center of the sprite
• size P - size of the sprite
