GameMaker (originally Animo, Game Maker (until 2011) and GameMaker Studio) is a series of cross-platform game engines created by Mark Overmars in 1999 and developed by YoYo Games since 2007. The latest iteration of GameMaker was released in 2022.
Allegro is a software library for video game development. [3] [4] [5] The functionality of the library includes support for basic 2D graphics, image manipulation, text output, audio output, MIDI music, input and timers, as well as additional routines for fixed-point and floating-point matrix arithmetic, Unicode strings, file system access, file manipulation, data files, and 3D graphics.
In electromagnetism, the Lorenz gauge condition or Lorenz gauge (after Ludvig Lorenz) is a partial gauge fixing of the electromagnetic vector potential by requiring = The name is frequently confused with Hendrik Lorentz , who has given his name to many concepts in this field. [ 1 ] (
Havok Script (discontinued): Havok Script is a Lua-compatible virtual machine designed for video game development. It is shipped as part of the Havok Script Studio. Havok Vision Engine (discontinued): In 2011, Havok acquired German game engine development company Trinigy and their Vision Engine and toolset. [10]
A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. [citation needed] The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ...
If ϕ is a velocity potential, then ϕ + f(t) is also a velocity potential for u, where f(t) is a scalar function of time and can be constant. Velocity potentials are unique up to a constant, or a function solely of the temporal variable. The Laplacian of a velocity potential is equal to the divergence of the corresponding flow.
Game-Maker 3.0, CD-ROM: this package includes the contents of the floppy package, plus first-party games Pipemare, Penguin Pete, Houses, and Terrain; A-J Games productions Glubada Pond, Crullo: Adventures of a Donut, Cireneg's Rings, and Linear Volume; two games by Sheldon Chase of KD Software, Woman Warrior and the Outer Limits and Woman ...
The ability to vary the gauge potential at different points in space and time (by changing (,)) without changing the physics is called a local invariance. Electromagnetic theory possess the simplest kind of local gauge symmetry called () (see unitary group). A theory that displays local gauge invariance is called a gauge theory.
