Pygame
------
### Example
### Basic Example
```python
# $ pip3 install pygame
import pygame as pg
pg.init()
screen = pg.display.set_mode((500, 500))
rect = pg.Rect(235, 235, 30, 30)
while all(event.type != pg.QUIT for event in pg.event.get()):
keys = {pg.K_UP: (0, -3), pg.K_RIGHT: (3, 0), pg.K_DOWN: (0, 3), pg.K_LEFT: (-3, 0)}
for delta in {keys.get(i) for i, on in enumerate(pg.key.get_pressed()) if on}:
rect = rect.move(delta) if delta else rect
screen.fill((0, 0, 0))
pg.draw.rect(screen, (255, 255, 255), rect)
pg.display.flip()
```
### Surface
**Object for representing images.**
```python
<Surface> = pg.display.set_mode((width, height)) # Retruns the display surface.
<Surface> = pg.Surface((width, height)) # Creates a new surface.
<Surface> = pg.image.load('<path>').convert() # Loads an image.
```
```python
<Surface>.set_at((x, y), <color>) # Updates pixel.
<Surface>.fill(<color>) # Fills the whole surface.
<Surface>.blit(<Surface>, (x, y)/<Rect>) # Draws passed surface to the surface.
<Surface> = <Surface>.subsurface(<Rect>) # Returns subsurface.
```
```python
<Surface> = pg.transform.flip(<Surface>, xbool, ybool)
<Surface> = pg.transform.rotate(<Surface>, angle)
<Surface> = pg.transform.scale(<Surface>, (width, height))
```
### Rect
**Object for storing rectangular coordinates.**
```python
<Rect> = pg.Rect(topleft_x, topleft_y, width, height) # x, y, w/width, h/height
<int> = <Rect>.x/y/centerx/centery/bottom/left/right/top
<tuple> = <Rect>.topleft/center/topright/bottomright/bottomleft
<tuple> = <Rect>.midtop/midright/midbottom/midleft
<bool> = <Rect>.contains(<Rect>)
```
```python
<Rect> = <Rect>.move(<tuple>/<int>, <int>)
<Rect>.move_ip(<tuple>/<int>, <int>)
<Rect> = <Rect>.inflate(<tuple>/<int>, <int>)
<Rect>.inflate_ip(<tuple>/<int>, <int>)
```
```python
<bool> = <Rect>.collidepoint(<tuple>/<int>, <int>)
<bool> = <Rect>.colliderect(<Rect>)
index = <Rect>.collidelist(<list_of_Rect>) # Returns index of first coliding Rect or -1.
indices = <Rect>.collidelistall(<list_of_Rect>) # Returns indices of all colinding Rects.
(key, value) = <Rect>.collidedict(<dict_of_Rect>)
[(key, value), ...] = <Rect>.collidedictall(<dict_of_Rect>)
```
### Draw
```python
pg.draw.rect(<Surface>, color, <Rect>)
pg.draw.polygon(<Surface>, color, points)
pg.draw.circle(<Surface>, color, center, radius)
pg.draw.ellipse(<Surface>, color, <Rect>)
pg.draw.arc(<Surface>, color, <Rect>, start_angle, stop_angle)
pg.draw.line(<Surface>, color, start_pos, end_pos, width)
pg.draw.lines(<Surface>, color, points)
```
