Functions and Events

By default any methods having the same signature of an internal virtual one (like ReceiveBeginPlay in the previous examples) will became

automagically an override. Pay attention to the function annotation style for helping the blueprint system discovering the type of arguments. Except from self, any argument (or return value) without proper type will result in ignoring the argument:

import unreal_engine as ue

from unreal_engine.classes import Character, PawnSensingComponent, Pawn, FloatProperty

class Hero(Character):

# you can set it from the editor as array

UpSpeed = [FloatProperty]

# automatic override

def ReceiveTick(self, DeltaSeconds: float):

location = self.get_actor_location()

location.z += self.UpSpeed[0] * DeltaSeconds

self.set_actor_location(location)

# this new method will be available to blueprints

def FunnyNewMethod(self, a_word: str):

ue.print_string('This is a word from blueprint: ' + a_word)

you can do manual override too:

import unreal_engine as ue

from unreal_engine.classes import Character, PawnSensingComponent, Pawn, FloatProperty

class Hero(Character):

# you can set it from the editor as array

UpSpeed = [FloatProperty]

# manual override

def funny_receive_tick(self, DeltaSeconds: float):

location = self.get_actor_location()

location.z += self.UpSpeed[0] * DeltaSeconds

self.set_actor_location(location)

funny_receive_tick.override = 'ReceiveTick'

To mark a method as 'pure' (in the Blueprint sense):

import unreal_engine as ue

from unreal_engine.classes import Character

class Hero(Character):

# this new method will be available to blueprints

def FunnyNewMethod(self, a_word: str):

ue.print_string('This is a word from blueprint: ' + a_word)

FunnyNewMethod.is_pure = True

or static:

import unreal_engine as ue

from unreal_engine.classes import Character

class Hero(Character):

# this new static method will be available to blueprints

def FunnyStaticMethod():

ue.print_string('I am a static method')

FunnyNewMethod.is_static = True
