The Blender Game Engine was a free and open-source 3D production suite used for making real-time interactive content. It was previously embedded within Blender, but support for it was dropped in 2019, with the release of Blender 2.8. The game engine was written from scratch in C++ as a mostly independent component, and includes support for features such as Python scripting and OpenAL 3D sound.

History

Blender Game Engine was developed in 2000 with the goal of creating a marketable commercial product to create games and other interactive content, in an artist-friendly way.

Key code in the physics library (SUMO) did not become open-source when the rest of Blender did, which prevented the game engine from functioning until version 2.37a.

Blender 2.41 showcased a version that was almost entirely devoted to the game engine; audio was supported.

Version 2.42 showed several significant new features, including integration of the Bullet rigid-body dynamics library.

Version 2.5 alpha0 was the first version of Blender to have the Logic Editor workspace for coding, which came along with the UI redesign.

A new system for integration of GLSL shaders and soft-body physics was added in the 2.48 release to help bring the game engine back in line with modern game engines. Like Blender, it uses OpenGL, a cross-platform graphics layer, to communicate with graphics hardware.

During the 2010 Google Summer of Code, the open-source navigation mesh construction and pathfinding libraries Recast and Detour were integrated; the work was merged to trunk in 2011. Audaspace was coded as well to provide a Python handle for sound control. This library uses OpenAL or SDL as a backend.

In 2019, with the release of Blender 2.8, the Blender Game Engine was entirely removed from Blender itself. [2] The engine's capabilities and appeal had largely fallen behind other rising game engines of the time, and it was difficult to update both Blender itself alongside the game engine. Users were instead recommended to use other, more powerful open source alternatives, like Godot. [3]

Following its removal from the official version of Blender, an unofficial fork of the game engine source code was created, named UPBGE (Uchronia Project Blender Game Engine). [4] This was done with the aim of maintaining and modernizing the engine. Since then, UPBGE has been updated with support for Blender's new realtime renderer, EEVEE, and runs on top of Blender 3.0 source code. [5]

Features

The Blender Game Engine uses a system of graphical "logic bricks" (a combination of "sensors", "controllers" and "actuators") to control the movement and display of objects. The game engine can also be extended via a set of Python bindings.

Crystal Space is an unmaintained framework for developing 3D applications written in C++ by Jorrit Tyberghein and others. The first public release was on August 26, 1997. It is typically used as a game engine but the framework is more general and can be used for any kind of 3D visualization. It is very portable and runs on Microsoft Windows, Linux, UNIX, and Mac OS X. It is also free and open-source software, licensed under the GNU LGPL-2.0-or-later, and was SourceForge.net's Project of the Month for February 2003. In 2019, one of the project's main developers described it as "effectively dead and has been for a good number of years".

It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox, PlayStation Portable, Symbian, iPhone, AmigaOS 4, Sailfish OS via a QT/Qml wrapper, and Google Native Client.

<span class="mw-page-title-main">Visual programming language</span> Programming language written graphically by a user

In computing, a visual programming language, also known as diagrammatic programming, graphical programming or block coding, is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations. VPLs are generally the basis of Low-code development platforms.

A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics, soft body dynamics, and fluid dynamics, of use in the domains of computer graphics, video games and film (CGI). Their main uses are in video games, in which case the simulations are in real-time. The term is sometimes used more generally to describe any software system for simulating physical phenomena, such as high-performance scientific simulation.
