The Main Loop

Grafyte applications run inside a frame loop:

import grafyte

app = grafyte.Application("My Game", (640, 360))
scene = app.make_new_scene()

while not app.should_close():
    app.render()

app.quit()

app.should_close() returns True when the user requests to close the window. app.render() processes window events and draws the current frame, so it must be called every iteration.

Frame Timing

Grafyte exposes frame timing as properties:

app.dt: elapsed time since the previous frame, in seconds
app.now: current engine time, in seconds

Example:

while not app.should_close():
    elapsed = app.now
    delta = app.dt
    app.render()

Shutdown

Call app.quit() once the loop ends so native resources are released cleanly.
