This is the most advanced way to use Python for your gameplay logic, developing plugins or automating tasks.

It resembles the native way you would work with unreal and c++ but in a (more or less ;) pythonic way.

The system is still under heavy development and new ideas are popping up constantly (the main objective is to simplify and speed up end-users development)

You can define new classes using standard python subclassing:

import unreal_engine as ue
from unreal_engine.classes import Character, PawnSensingComponent, Pawn

class Monster(Character):

    def __init__(self):
        sensor = self.add_actor_component(PawnSensingComponent, 'Sensor')
        sensor.SightRadius = 17000
        
    def OnSeePawn(self, pawn : Pawn):
        ue.print_string('seen {}'.format(pawn))
