set_state_machine(new_msg: simulation_evaluation.msg._State.State, state_machine: simulation.src.simulation_evaluation.src.state_machine.state_machines.state_machine.StateMachine)[source]¶

Update state machine manually.

Parameters

new_msg – Message of the state to which the state machine should be set to
state_machine (StateMachine) – State machine to be changed
