AngelScript

AngelScript is an open-source game-oriented compiled scripting language developed by Andreas Jönsson at AngelCode.

AngelScript features static typing, object handles (similar to C++ pointers but garbage collected via reference counting), object-orientation, single inheritance, multiple inheritance with interfaces. Allows operators to be registered and overloaded. AngelScript can be used with any C++ IDE, such as NetBeans, Geany, and Eclipse.

C and C++ functions can be called within an AngelScript environment.[1][2] AngelScript's class syntax closely follows C++ classes by design: no proxy functions are required to embed AngelScript in C++ applications easing the two languages integration.[3] There are several differences of AngelScript and C++:

• AngelScript does not support multiple inheritance. Multiple-inheritance functionality may be achieved with Interfaces.
• It is impossible to declare methods or properties outside of the class body.
• All methods (including constructors and destructors) are virtual.

AngelScript is used in video game development,[4] including Amnesia: The Dark Descent,[5] Amy,[5] Dustforce,[5] Gekkeiju Online,[5] King Arthur's Gold,[5] Legend of the Guardians: The Owls of Ga'Hoole,[5] Overgrowth,[6] Penumbra: Overture,[5] Penumbra: Requiem,[5] Puddle,[5] Rigs of Rods,[5] Sine Mora,[5] Star Ruler,[5] SuperTuxKart,[5] Warhammer: Mark of Chaos,[5] Warsow,[5] Sven Co-op[5] and Jazz Jackrabbit 2 Plus,[5] in addition to being supported as a scripting language in Urho3D. Hazelight Studios maintains a plugin that integrates AngelScript into the Unreal Engine; this plugin was used to write their newest game, It Takes Two, in AngelScript.[7] It is also used at the University of Ulm in its interactive 3D-Animation program,[8] as well as in robotics; for example, to program behavioral rules of robotic agents.[9]
