Configuration¶

The custom_grid_env can be customized via various parameters, primarily through the AgentInterface.

AgentInterface Parameters¶

When initializing the AgentInterface, the following parameters can be passed:

Parameter	Type	Default	Description
`render`	bool	`True`	Enables graphical display via Pygame.
`render_mode`	str	`None`	The mode to render with ("human" or "rgb_array"). Defaults to "rgb_array" if `render=True`.
`step_delay`	int	`100`	Delay in milliseconds between steps when rendering.
`slip_probability`	float	`0.2`	Probability (0.0 to 1.0) of the agent slipping.
`slip_type`	str	`"longitudinal"`	Type of slipping ("longitudinal" or "perpendicular").
`ghost_agent_class`	Type	`ChaseGhostAgent`	Class that controls the ghost's behavior.
`use_particle_filter`	bool	`True`	Whether to use the particle filter for state estimation.
`pf_num_particles`	int	`200`	Number of particles in the filter.
`pf_sensor_mode`	str	`"both"`	Sensor mode for the PF ("color", "cnn", or "both").
`show_particles`	bool	`True`	Whether to show particles in the renderer.

Example Configuration¶

from custom_grid_env.interface import AgentInterface
from custom_grid_env.agents.random_ghost_agent import RandomGhostAgent

interface = AgentInterface(
    render=True,
    slip_probability=0.1,
    slip_type="perpendicular",
    ghost_agent_class=RandomGhostAgent,
    pf_num_particles=500
)
