    void move(int dx, int dy) {
        x += dx;
        y += dy;
    }
};

int main() {
    Player player;
    player.x = player.y = 0;
    player.move(5, 3);
    std::cout << "Posição do jogador: " << player.x << ", " << player.y << std::endl;
    return 0;
}

2. Python

Python is a great choice for 2D games and rapid prototyping. Although it's not as fast as C++, Python offers simplicity and readability. With libraries like Pygame, developers can create 2D games in an intuitive and efficient way.

Python is a more beginner-friendly language, widely used for rapid game prototyping. It is highly readable, which makes it ideal for developing simple games or for building the game's logic before implementing it in a higher-performance language. The Pygame library makes it easy to develop 2D games with basic sound and graphics features.

Programming languages for game development: Why use Python?

• Not recommended for large-scale games: For high-end 3D games or graphics-intensive applications, Python is less efficient.

Python code example with Pygame for movement:

import pygame
pygame.init()

win = pygame.display.set_mode((500, 500))
pygame.display.set_caption("Jogo com Pygame")

x, y = 50, 50
velocidade = 5
running = True

while running:
    pygame.time.delay(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        x -= velocidade
    if keys[pygame.K_RIGHT]:
        x += velocidade
    if keys[pygame.K_UP]:
        y -= velocidade
    if keys[pygame.K_DOWN]:
        y += velocidade

    win.fill((0,0,0))
    pygame.draw.rect(win, (255, 0, 0), (x, y, 40, 60))
    pygame.display.update()

pygame.quit()

3. C#
