SFML

Drop shadows are created using a Gaussian blur drawn underneath the original element. You can do this using either a fixed texture or a post-processing fragment shader.

SFML is an excellent library that can be used to create 2D games in C++. It’s an abstraction over OpenGL and various system APIs, presenting a consistent and nice interface.

There are many different approaches and use-cases to creating GUIs which a standard approach embedded in SFML would not be able to cover, which is why SFML leaves it to other libraries. Additionally, whilst the S in SFML stands for Simple, GUI code rarely is.

There are many different options to choose from when attempting to implement GUIs, some of these will be detailed below.

Ruben’s Virtual World Project is a game I’ve been working on for almost 4 years now. Recently I rewrote the rendering code to support voxel lighting and multiple z-level - heights of the map.

For the last two years, I have been working on a very ambitious game. The game is a top-down sandbox with multiplayer support. I’m aiming towards a city-based game, where players can wander around a procedurally generated city. One of the main reasons I started creating this game is to learn about multiplayer networking at a low level - client-side prediction, server-side reconcilliation, cheat preventation, and reducing the visual effect of latency.

Usecase: shells dropping in sync with firing, fake bullets, etc

You must use a particle emitter to create particles, however this doesn’t mean it’s impossible to create single particles on command. You can create a particle emitter which simply adds particles from a queue to the system

Simply get the SFGUI window size using GetAllocation, the sfml window size using getSize, then do this arithmetic:

auto window = sfg::Window::Create();
auto win_rect = window->GetAllocation();
sf::Vector2f size(win_rect.width, win_rect.height);
window->SetPosition(((sf::Vector2f)rwindow->getSize() - size) / 2.0f);
