animation_reset interface

This page explains the animation_reset method interface.

What interface is this?

The animation_reset interface resets all animations and stop.

This interface exists in the instances that have the animation interfaces (such as the animation_x, animation_move).

Basic usage

The following example sets the click event to the rectangle. If you click the rectangle, the x-coordinate animation starts. After 1 second has passed, the animation_reset interface resets the x-coordinate animation:

from typing_extensions import TypedDict

import apysc as ap


class _RectOptions(TypedDict):
    rectangle: ap.Rectangle


def on_click(e: ap.MouseEvent[ap.Rectangle], options: dict) -> None:
    """
    The handler that the rectangle calls when clicked.

    Parameters
    ----------
    e : ap.Rectangle
        Event instance.
    options : dict
        Optional arguments dictionary.
    """
    e.this.animation_x(x=500, duration=3000).start()
    options_: _RectOptions = {"rectangle": e.this}
    timer: ap.Timer = ap.Timer(on_timer, delay=1000, repeat_count=1, options=options_)
    timer.start()


def on_timer(e: ap.TimerEvent, options: _RectOptions) -> None:
    """
    The handler that the timer calls.

    Parameters
    ----------
    e : ap.TimerEvent
        Event instance.
    options : _RectOptions
        Optional arguments dictionary.
    """
    options["rectangle"].animation_reset()


ap.Stage(
    stage_width=600,
    stage_height=150,
    background_color=ap.Color("#333"),
    stage_elem_id="stage",
)
sprite: ap.Sprite = ap.Sprite()
sprite.graphics.begin_fill(color=ap.Color("#00aaff"))
rectangle: ap.Rectangle = sprite.graphics.draw_rect(x=50, y=50, width=50, height=50)
rectangle.click(on_click)

ap.save_overall_html(dest_dir_path="./animation_reset_basic_usage/")

[Interface signature] animation_reset(self) -> None

[Interface summary]
