class bruhanimate.bruhrenderer.base_renderer.BaseRenderer(screen: Screen, frames: int = 100, frame_time: float = 0.1, effect_type: Literal['static', 'offset', 'noise', 'stars', 'plasma', 'gol', 'rain', 'matrix', 'drawlines', 'snow', 'twinkle', 'audio', 'chat', 'firework', 'fire', 'julia'] = 'static', background: str = ' ', transparent: bool = False, collision: bool = False)

Bases: object

Base class for rendering effects on the screen.

__init__(screen: Screen, frames: int = 100, frame_time: float = 0.1, effect_type: Literal['static', 'offset', 'noise', 'stars', 'plasma', 'gol', 'rain', 'matrix', 'drawlines', 'snow', 'twinkle', 'audio', 'chat', 'firework', 'fire', 'julia'] = 'static', background: str = ' ', transparent: bool = False, collision: bool = False)

validate_effect_type(effect_type: Literal['static', 'offset', 'noise', 'stars', 'plasma', 'gol', 'rain', 'matrix', 'drawlines', 'snow', 'twinkle', 'audio', 'chat', 'firework', 'fire', 'julia']) → None

Validates the provided effect type against a list of valid effect types.

Parameters:

effect_type (EffectType) – The effect type to be validated.

Raises:

InvalidEffectTypeError – If the provided effect type is not valid.

create_effect(effect_type: Literal['static', 'offset', 'noise', 'stars', 'plasma', 'gol', 'rain', 'matrix', 'drawlines', 'snow', 'twinkle', 'audio', 'chat', 'firework', 'fire', 'julia']) → object

Creates an instance of the specified effect type.

Parameters:

effect_type (EffectType) – The type of effect to be created.

Returns:

An instance of the specified effect type.

Raises:

ValueError – If the provided effect type is not recognized.

create_buffer() → Buffer

Creates a new buffer with the specified height and width.

Args:

Returns:

A newly created buffer object.

update_collision(collision: bool)

Updates the effect’s collision state.

Parameters:

collision (bool) – The new collision state.

Returns:

None

update_smart_transparent(smart_transparent: bool)

Updates the effect’s smart transparent state.

Parameters:

smart_transparent (bool) – The new smart transparent state.

Returns:

None

push_front_to_screen()

Pushes the front buffer to the screen.

Returns:

None

render_exit()

Renders an exit message on the screen.

Returns:

None

run(end_message=True)

Runs the renderer for a specified number of frames or indefinitely.

Parameters:

end_message (bool) – Whether to render an exit message after finishing. Defaults to True.

Returns:

None

update_exit_stats(msg1=None, msg2=None, wipe=None, x_loc=None, y_loc=None, centered=False)

Updates the exit message statistics. :param msg1: The first line of the exit message. Defaults to None. :type msg1: str :param msg2: The second line of the exit message. Defaults to None. :type msg2: str :param wipe: Whether to clear the screen before rendering the exit message. Defaults to False. :type wipe: bool :param x_loc: The x-coordinate of the exit message. Defaults to 0. :type x_loc: int :param y_loc: The y-coordinate of the exit message. Defaults to 1. :type y_loc: int :param centered: Whether to center the exit message horizontally. Defaults to True. :type centered: bool

Returns:

None

abstract render_frame()

Renders a single frame of the effect.

Returns:

None
