🔒 Pygame Tutorial help

[elder quarry]

I'm watching a pygame tutorial and there's an update function they use. Can someone explain what it does please, when I search online it's talking about dictionaries only

it's a method of whatever is in PhysicsEntity

open scripts.entities

it might be custom and not a native pygame class

[elder quarry]

import pygame

class PhysicsEntity:
    def __init__(self, game, e_type, position, size):
        self.game = game
        self.type = e_type
        self.position = list(position)
        self.size = size
        self.velocity = [0, 0]
   
    def update(self, movement=(0, 0)):
        frame_movement = (movement[0] + self.velocity[0], movement[1] + self.velocity[1])

        self.position[0] += frame_movement[0]
        self.position[1] += frame_movement[1]

    def render(self, surface):
        surface.blit(self.game.assets['player'], self.position)

This is entities file

Is there a specific part you're confused about?

Are you familiar with OOP?

[iron tapir]

now you can see here what update does

[elder quarry]

I'm just wondering what ```py
self.player.update((self.movement[1] - self.movement[0], 0))

does

[elder quarry]

ooooooooooooooooooooooooooooooooooooooooohhhhhhhhhhhhhhhhhhhhhhhh

sorry I made a silly error

I didn't see that

[elder quarry]

a bit

thanks guys

When you do arithmetic operations with a boolean, it parses True as 1 and False as 0

[iron tapir]

def update(self, movement=(0, 0)):
    frame_movement = (movement[0] + self.velocity[0], movement[1] + self.velocity[1])

    self.position[0] += frame_movement[0]
    self.position[1] += frame_movement[1]

this is what self.player.update will call

[elder quarry]

mhm I understood but was wondering what the update() does

[elder quarry]

yea thanks a lot
