mxbiflow 0.3.14

mxbiflow is a toolkit based on pygame and pymxbi

mxbiflow

A framework for building multi-animal, multi-stage behavioral neuroscience experiments with touchscreen interfaces.

Overview

mxbiflow provides the core infrastructure for cognitive and behavioral experiment scheduling. It handles the experiment lifecycle — from configuration wizards and session management to real-time scene rendering and data logging — so you can focus on designing your experiment logic.

Usage

Implement your experiment as a set of scenes, register them, and launch:

from mxbiflow import set_base_path
from mxbiflow.scene import SceneManager
from mxbiflow.wizard import config_wizard, init_gameloop

scene_manager = SceneManager()
scene_manager.register([IDLE, Detect, Discriminate])

config_wizard(scene_manager)
game = init_gameloop(scene_manager, max_fps=120)
game.play()

Each scene implements SceneProtocol:

class MyScene:
    _running: bool
    level_table: dict[str, list[int]] = {"default": [1, 2, 3]}

    def start(self) -> None: ...
    def quit(self) -> None: ...
    @property
    def running(self) -> bool: ...
    def handle_event(self, event: Event) -> None: ...
    def update(self, dt_s: float) -> None: ...
    def draw(self, screen: Surface) -> None: ...
