Handling Input

Grafyte exposes input through app.input.

Raw Key States

The input manager provides three accessors:

• app.input.key[Key.X] for keys currently held down

• app.input.key_pressed[Key.X] for the frame a key was pressed

• app.input.key_released[Key.X] for the frame a key was released

Example:

import grafyte
from grafyte import Key

app = grafyte.Application("Input Example", (640, 360))

RED = (255, 0, 0)
GREEN = (0, 255, 0)
GRAY = (127, 127, 127)

app.background_color = GRAY

while not app.should_close():
    if app.input.key_pressed[Key.R]:
        app.background_color = RED
    elif app.input.key_pressed[Key.G]:
        app.background_color = GREEN

    app.render()

app.quit()

Use key_pressed for one-frame actions such as toggles, and key for continuous movement.
