Very simple Processing (Java)program that "simulates" Gravitational Motion, it´s perfect for getting started with OPP programming and learning the basic concepts of it. I just made it for entertaining purposes some days ago :)
EN: It's a very simple program with highly customizable settings and easy-to-read code. It's perfect for those who want to get started with Object-Oriented Programming. The Physics part of the code is also beginner-friendly, it just uses Newton´s gravitation law, nothing too fancy.
PD: I am a Spanish speaker so in the code, many variables, functions etc... are named in my language, be aware of that :)
ES: Es un programa muy simple con configuraciones altamente personalizables y código fácil de leer. Es perfecto para aquellos que quieran comenzar con la programación orientada a objetos. La parte Physycs del código también es amigable para los principiantes, solo usa la ley de gravitación de Newton, nada para imaginar.
