run_backend(domain='./examples/pddl/blocks/domain.pddl', problem='./examples/pddl/blocks/problem.pddl')

CLI Mode

• Provide your domain and problem files.

python pdsim_unity.py --domain <domain_path> --problem <problem_path>

You can provide an optional --planner flag, by default it'll use fast-downward, but the user will be prompted which planner is available for a specific problem.

• Embed pdsim server in your up problem definition.

from pdsim_unity import pdsim_upf

< your  problem definition >

pdsim_upf(up_problem, planner_name)

This will create a server to communicate with unity and serve the protobuf representation of the problem and the generated plan.
