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.
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 ...
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.
In electromagnetism, the Lorenz condition is generally used in calculations of time-dependent electromagnetic fields through retarded potentials. [2] The condition is , =, where is the four-potential, the comma denotes a partial differentiation and the repeated index indicates that the Einstein summation convention is being used.
Game-Maker (aka RSD Game-Maker) is an MS-DOS-based suite of game design tools, accompanied by demonstration games, produced between 1991 and 1995 by the Amherst, New Hampshire based Recreational Software Designs and sold through direct mail in the US by KD Software. [1] Game-Maker also was sold under various names by licensed distributors in ...
If it is possible to find from the constraints as many independent variables as there are degrees of freedom, these can be used as generalized coordinates. [5] The position vector r k of particle k is a function of all the n generalized coordinates (and, through them, of time), [6] [7] [8] [5] [nb 1]
ϕ is known as a velocity potential for u. A velocity potential is not unique. 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.
GDevelop is a 2D and 3D cross-platform, free and open-source game engine, which mainly focuses on creating PC and mobile games, as well as HTML5 games playable in the browser. [ 4 ] [ 5 ] [ 6 ] Created by Florian Rival, a software engineer at Google , [ 7 ] GDevelop is mainly aimed at non-programmers and game developers of all skillsets ...
